Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is a continuation of U.S. patent application Ser. No. 15/844,409, filed Dec. 15, 2017 (now U.S. Pat. No. 10,839,002), which claims the benefit of prior filed U.S. Provisional Patent Application No. 62/514,910, filed Jun. 4, 2017, each of which is hereby incorporated by reference herein in its entirety. 
    
    
     TECHNICAL FIELD 
     This disclosure relates to defining a collection of media content items for a relevant interest with an electronic device. 
     BACKGROUND OF THE DISCLOSURE 
     A system may be provided for managing a library of media items. Often, however, management of such a library may fail to identify certain media items as being indicative of a relevant interest of a user. 
     SUMMARY OF THE DISCLOSURE 
     This document describes systems, methods, and computer-readable media for defining a collection of media content items of a media library for a relevant interest with an electronic device. 
     For example, a non-transitory machine readable medium storing a program for execution by at least one processing unit of a device may be provided, the program for managing a media library, the program including sets of instructions for accessing a plurality of media content items (MCIs) of the media library and metadata associated with the media library, wherein the metadata defines a plurality of moments, each moment of the plurality of moments is associated with a subset of MCIs of the plurality of MCIs, and each MCI of the subset of MCIs that is associated with a particular moment is associated with geographical metadata indicative of a geographic location within a particular geographic range associated with the particular moment and temporal metadata indicative of a time within a particular time range associated with the particular moment, analyzing the plurality of MCIs and the metadata, wherein the analyzing includes identifying a plurality of first person-residence moments from the plurality of moments, wherein each first person-residence moment of the plurality of first person-residence moments is a moment of the plurality of moments that is associated with both a first person and a residence of the first person, and identifying an interest that is associated with each one of a first number of first person-residence moments of the plurality of first person-residence moments, wherein the first number is greater than a threshold value, and defining a collection of MCIs of the plurality of MCIs, wherein each MCI of the collection of MCIs is associated with a moment of the plurality of moments that is associated with both the first person and the interest. 
     As another example, a method of managing a media library with a computing system may include accessing, with the computing system, a plurality of media content items (MCIs) of the media library and metadata associated with the media library, wherein the metadata defines a plurality of moments, each moment of the plurality of moments is associated with a subset of MCIs of the plurality of MCIs, and each MCI of the subset of MCIs that is associated with a particular moment is associated with temporal metadata indicative of a time within a particular time range associated with the particular moment, analyzing, with the computing system, the plurality of MCIs and the metadata, wherein the analyzing includes identifying at least one person-residence moment from the plurality of moments, wherein each person-residence moment of the at least one person-residence moment is a moment of the plurality of moments that is associated with a location intimately associated with a person identity, and identifying an interest that is associated with at least one of the at least one person-residence moment, and defining, with the computing system, a collection of MCIs of the plurality of MCIs, wherein each MCI of the collection of MCIs is associated with the identified interest. 
     As yet another example, a method of managing a media library with a computing system may include accessing, with the computing system, a plurality of media content items (MCIs) of the media library, identifying, with the computing system, at least a threshold number of MCIs of the plurality of MCIs that are associated with both a particular person entity and a particular interest, and defining, with the computing system, a collection of MCIs of the plurality of MCIs, wherein each MCI of the collection of MCIs is associated with the particular interest.

     DETAILED DESCRIPTION OF THE DISCLOSURE 
     Systems, methods, and computer-readable media may be provided to define a collection of media content items of a media library for a relevant interest. For example, a combination of a particular interest and a particular person identity may be identified based on analysis of a media library of media content items (“MCIs”) in order to determine whether the particular interest is relevant to the person identity. For example, a location may be determined to be intimately associated with the person identity (e.g., a home or place of business of the person identity), and then it may be determined whether the particular interest may be associated with a particular threshold amount of MCIs (or moments of MCIs) also associated with any such intimate location. Some or all MCIs determined to be associated with a relevant interest of a person identity may be used to define an MCI collection for any suitable purpose (e.g., for defining an easily accessible album of such MCIs or for generating a composite presentation of the MCIs for user enjoyment). 
       FIG.  1    is a schematic view of an illustrative system  1  that may include at least one of electronic device  100  and remote server  50  for defining a collection of media content items for a relevant interest in accordance with some embodiments. Electronic device  100  can include, but is not limited to, a media player (e.g., an iPod™ available by Apple Inc. of Cupertino, Calif.), video player, still image player, game player, other media player, music recorder, movie or video camera or recorder, still camera, other media recorder, radio, medical equipment, domestic appliance, transportation vehicle instrument, musical instrument, calculator, cellular telephone (e.g., an iPhone™ available by Apple Inc.), other wireless communication device, personal digital assistant, remote control, pager, computer (e.g., a desktop, laptop, tablet (e.g., an iPad™ available by Apple Inc.), server, etc.), monitor, television, stereo equipment, set up box, set-top box, boom box, modem, router, printer, watch, biometric monitor, or any combination thereof. In some embodiments, electronic device  100  may perform a single function (e.g., a device dedicated to defining a collection of media content items for a relevant interest) and, in other embodiments, electronic device  100  may perform multiple functions (e.g., a device that manages a media library, plays music, and receives and transmits telephone calls). Electronic device  100  may be any portable, mobile, hand-held, or miniature electronic device that may be configured to define a collection of media content items for a relevant interest wherever a user travels. Some miniature electronic devices may have a form factor that is smaller than that of hand-held electronic devices, such as an iPod™. Illustrative miniature electronic devices can be integrated into various objects that may include, but are not limited to, watches (e.g., an Apple Watch™ available by Apple Inc.), rings, necklaces, belts, accessories for belts, headsets, accessories for shoes, virtual reality devices, glasses, other wearable electronics, accessories for sporting equipment, accessories for fitness equipment, key chains, or any combination thereof. Alternatively, electronic device  100  may not be portable at all, but may instead be generally stationary. 
     As shown in  FIG.  1   , for example, electronic device  100  may include processing circuitry  102 , memory  104 , power supply circuitry  106 , input component circuitry  108 , output component circuitry  110 , sensor circuitry  112 , and communications circuitry  114 . Electronic device  100  may also include a bus  115  that may provide one or more wired or wireless communication links or paths for transferring data and/or power to, from, or between various other components of device  100 . In some embodiments, one or more components of electronic device  100  may be combined or omitted. Moreover, electronic device  100  may include any other suitable components not combined or included in  FIG.  1    and/or several instances of the components shown in  FIG.  1   . For the sake of simplicity, only one of each of the components is shown in  FIG.  1   . 
     Memory  104  may include one or more storage mediums, including, for example, a hard-drive, flash memory, permanent memory such as read-only memory (“ROM”), semi-permanent memory such as random access memory (“RAM”), any other suitable type of storage component, or any combination thereof. Memory  104  may include cache memory, which may be one or more different types of memory used for temporarily storing data for electronic device applications. Memory  104  may be fixedly embedded within electronic device  100  or may be incorporated onto one or more suitable types of cards that may be repeatedly inserted into and removed from electronic device  100  (e.g., a subscriber identity module (“SIM”) card or secure digital (“SD”) memory card). Memory  104  may store media data (e.g., music and image files), software (e.g., for implementing functions on device  100 ), firmware, media information (e.g., media content and/or associated metadata), preference information (e.g., media playback preferences), lifestyle information (e.g., food preferences), exercise information (e.g., information obtained by exercise monitoring equipment or any suitable sensor circuitry), transaction information (e.g., information such as credit card information), wireless connection information (e.g., information that may enable device  100  to establish a wireless connection), subscription information (e.g., information that keeps track of podcasts or television shows or other media a user subscribes to), contact information (e.g., telephone numbers and e-mail addresses), calendar information, pass information (e.g., transportation boarding passes, event tickets, coupons, store cards, financial payment cards, etc.), any other suitable data, or any combination thereof. 
     Power supply circuitry  106  can include any suitable circuitry for receiving and/or generating power, and for providing such power to one or more of the other components of electronic device  100 . For example, power supply circuitry  106  can be coupled to a power grid (e.g., when device  100  is not acting as a portable device or when a battery of the device is being charged at an electrical outlet with power generated by an electrical power plant). As another example, power supply circuitry  106  can be configured to generate power from a natural source (e.g., solar power using solar cells). As another example, power supply circuitry  106  can include one or more batteries for providing power (e.g., when device  100  is acting as a portable device). For example, power supply circuitry  106  can include one or more of a battery (e.g., a gel, nickel metal hydride, nickel cadmium, nickel hydrogen, lead acid, or lithium-ion battery), an uninterruptible or continuous power supply (“UPS” or “CPS”), and circuitry for processing power received from a power generation source (e.g., power generated by an electrical power plant and delivered to the user via an electrical socket or otherwise). The power can be provided by power supply circuitry  106  as alternating current or direct current, and may be processed to transform power or limit received power to particular characteristics. For example, the power can be transformed to or from direct current, and constrained to one or more values of average power, effective power, peak power, energy per pulse, voltage, current (e.g., measured in amperes), or any other characteristic of received power. Power supply circuitry  106  can be operative to request or provide particular amounts of power at different times, for example, based on the needs or requirements of electronic device  100  or periphery devices that may be coupled to electronic device  100  (e.g., to request more power when charging a battery than when the battery is already charged). 
     One or more input components  108  may be provided to permit a user to interact or interface with device  100 . For example, input component circuitry  108  can take a variety of forms, including, but not limited to, a touch pad, dial, click wheel, scroll wheel, touch screen, one or more buttons (e.g., a keyboard), mouse, joy stick, track ball, microphone, still image camera, video camera, scanner (e.g., a bar code scanner or any other suitable scanner that may obtain product identifying information from a code, such as a bar code, or the like), proximity sensor, light detector, biometric sensor (e.g., a fingerprint reader or other feature recognition sensor, which may operate in conjunction with a feature-processing application that may be accessible to electronic device  100  for authenticating a user), line-in connector for data and/or power, and combinations thereof. Each input component  108  can be configured to provide one or more dedicated control functions for making selections or issuing commands associated with operating device  100 . 
     Electronic device  100  may also include one or more output components  110  that may present information (e.g., graphical, audible, and/or tactile information) to a user of device  100 . For example, output component circuitry  110  of electronic device  100  may take various forms, including, but not limited to, audio speakers, headphones, line-out connectors for data and/or power, visual displays, infrared ports, tactile/haptic outputs (e.g., rumblers, vibrators, etc.), and combinations thereof. As a particular example, electronic device  100  may include a display output component as output component  110 , where such a display output component may include any suitable type of display or interface for presenting visual data to a user. A display output component may include a display embedded in device  100  or coupled to device  100  (e.g., a removable display). A display output component may include, for example, a liquid crystal display (“LCD”), a light emitting diode (“LED”) display, an organic light-emitting diode (“OLED”) display, a surface-conduction electron-emitter display (“SED”), a carbon nanotube display, a nanocrystal display, any other suitable type of display, or combination thereof. Alternatively, a display output component can include a movable display or a projecting system for providing a display of content on a surface remote from electronic device  100 , such as, for example, a video projector, a head-up display, or a three-dimensional (e.g., holographic) display. As another example, a display output component may include a digital or mechanical viewfinder, such as a viewfinder of the type found in compact digital cameras, reflex cameras, or any other suitable still or video camera. A display output component may include display driver circuitry, circuitry for driving display drivers, or both, and such a display output component can be operative to display content (e.g., media playback information, application screens for applications implemented on electronic device  100 , information regarding ongoing communications operations, information regarding incoming communications requests, device operation screens, etc.) that may be under the direction of processor  102 . 
     It should be noted that one or more input components and one or more output components may sometimes be referred to collectively herein as an input/output (“I/O”) component or I/O circuitry or I/O interface (e.g., input component  108  and output component  110  as I/O component or I/O interface  109 ). For example, input component  108  and output component  110  may sometimes be a single I/O component  109 , such as a touch screen, that may receive input information through a user&#39;s touch (e.g., multi-touch) of a display screen and that may also provide visual information to a user via that same display screen. 
     Sensor circuitry  112  may include any suitable sensor or any suitable combination of sensors operative to detect movements of electronic device  100  and/or any other characteristics of device  100  or its environment (e.g., physical activity or other characteristics of a user of device  100 ). For example, sensor circuitry  112  may include one or more three-axis acceleration motion sensors (e.g., an accelerometer) that may be operative to detect linear acceleration in three directions (i.e., the x- or left/right direction, the y- or up/down direction, and the z- or forward/backward direction). As another example, sensor circuitry  112  may include one or more single-axis or two-axis acceleration motion sensors that may be operative to detect linear acceleration only along each of the x- or left/right direction and the y- or up/down direction, or along any other pair of directions. In some embodiments, sensor circuitry  112  may include an electrostatic capacitance (e.g., capacitance-coupling) accelerometer that may be based on silicon micro-machined micro electro-mechanical systems (“MEMS”) technology, including a heat-based MEMS type accelerometer, a piezoelectric type accelerometer, a piezo-resistance type accelerometer, and/or any other suitable accelerometer (e.g., which may provide a pedometer or other suitable function). In some embodiments, sensor circuitry  112  may be operative to directly or indirectly detect rotation, rotational movement, angular displacement, tilt, position, orientation, motion along a non-linear (e.g., arcuate) path, or any other non-linear motions. Additionally or alternatively, sensor circuitry  112  may include one or more angular rate, inertial, and/or gyro-motion sensors or gyroscopes for detecting rotational movement. For example, sensor circuitry  112  may include one or more rotating or vibrating elements, optical gyroscopes, vibrating gyroscopes, gas rate gyroscopes, ring gyroscopes, magnetometers (e.g., scalar or vector magnetometers), compasses, and/or the like. Any other suitable sensors may also or alternatively be provided by sensor circuitry  112  for detecting motion on device  100 , such as any suitable pressure sensors, altimeters, or the like. Using sensor circuitry  112 , electronic device  100  may be configured to determine a velocity, acceleration, orientation, and/or any other suitable motion attribute of electronic device  100 . 
     Sensor circuitry  112  may include any suitable sensor(s), including, but not limited to, one or more of a GPS sensor, accelerometer, directional sensor (e.g., compass), gyroscope, motion sensor, pedometer, passive infrared sensor, ultrasonic sensor, microwave sensor, a tomographic motion detector, a camera, a biometric sensor, a light sensor, a timer, or the like. In some examples, a biometric sensor may include, but is not limited to, one or more health-related optical sensors, capacitive sensors, thermal sensors, electric field (“eField”) sensors, and/or ultrasound sensors, such as photoplethysmogram (“PPG”) sensors, electrocardiography (“ECG”) sensors, galvanic skin response (“GSR”) sensors, posture sensors, stress sensors, photoplethysmogram sensors, and/or the like. These sensors can generate data providing health-related information associated with the user. For example, PPG sensors can provide information regarding a user&#39;s respiratory rate, blood pressure, and/or oxygen saturation. ECG sensors can provide information regarding a user&#39;s heartbeats. GSR sensors can provide information regarding a user&#39;s skin moisture, which may be indicative of sweating and can prioritize a thermostat application to determine a user&#39;s body temperature. In some examples, each sensor can be a separate device, while, in other examples, any combination of two or more of the sensors can be included within a single device. For example, a gyroscope, accelerometer, photoplethysmogram, galvanic skin response sensor, and temperature sensor can be included within a wearable electronic device, such as a smart watch, while a scale, blood pressure cuff, blood glucose monitor, SpO2 sensor, respiration sensor, posture sensor, stress sensor, and asthma inhaler can each be separate devices. While specific examples are provided, it should be appreciated that other sensors can be used and other combinations of sensors can be combined into a single device. Using one or more of these sensors, device  100  can determine physiological characteristics of the user while performing a detected activity, such as a heart rate of a user associated with the detected activity, average body temperature of a user detected during the detected activity, any normal or abnormal physical conditions associated with the detected activity, or the like. In some examples, a GPS sensor or any other suitable location detection component(s) of device  100  can be used to determine a user&#39;s location and movement, as well as a displacement of the user&#39;s motion. An accelerometer, directional sensor, and/or gyroscope can further generate activity data that can be used to determine whether a user of device  100  is engaging in an activity, is inactive, or is performing a gesture. Device  100  can further include a timer that can be used, for example, to add time dimensions to various attributes of the detected physical activity, such as a duration of a user&#39;s physical activity or inactivity, time(s) of a day when the activity is detected or not detected, and/or the like. One or more sensors of sensor circuitry or component  112  may be embedded in a body (e.g., housing  101 ) of device  100 , such as a long a bottom surface that may be operative to contact a user, or can be positioned at any other desirable location. In some examples, different sensors can be placed in different locations inside or on the surfaces of device  100  (e.g., some located inside housing  101 ) and some attached to an attachment mechanism (e.g., a wrist band coupled to a housing of a wearable device), or the like. In other examples, one or more sensors can be worn by a user separately from device  100 . In such cases, the sensors can be configured to communicate with device  100  using a wired and/or wireless technology (e.g., via communications circuitry  114 ). In some examples, sensors can be configured to communicate with each other and/or share data collected from one or more sensors. In some other examples, device  100  can be waterproof such that the sensors can detect a user&#39;s activity in water. 
     Communications circuitry  114  may be provided to allow device  100  to communicate with one or more other electronic devices or servers using any suitable communications protocol. For example, communications circuitry  114  may support Wi-Fi™ (e.g., an 802.11 protocol), ZigBee™ (e.g., an 802.15.4 protocol), WiDi™, Ethernet, Bluetooth™, Bluetooth™ Low Energy (“BLE”), high frequency systems (e.g., 900 MHz, 2.4 GHz, and 5.6 GHz communication systems), infrared, transmission control protocol/internet protocol (“TCP/IP”) (e.g., any of the protocols used in each of the TCP/IP layers), Stream Control Transmission Protocol (“SCTP”), Dynamic Host Configuration Protocol (“DHCP”), hypertext transfer protocol (“HTTP”), BitTorrent™, file transfer protocol (“FTP”), real-time transport protocol (“RTP”), real-time streaming protocol (“RTSP”), real-time control protocol (“RTCP”), Remote Audio Output Protocol (“RAOP”), Real Data Transport Protocol™ (“RDTP”), User Datagram Protocol (“UDP”), secure shell protocol (“SSH”), wireless distribution system (“WDS”) bridging, any comniunications protocol that may be used by wireless and cellular telephones and personal e-mail devices (e.g., Global System for Mobile Communications (“GSM”), GSM plus Enhanced Data rates for GSM Evolution (“EDGE”), Code Division Multiple Access (“CDMA”), Orthogonal Frequency-Division Multiple Access (“OFDMA”), high speed packet access (“HSPA”), multi-band, etc.), any communications protocol that may be used by a low power Wireless Personal Area Network (“6LoWPAN”) module, Near Field Communication (“NFC”), any other communications protocol, or any combination thereof. Communications circuitry  114  may also include or be electrically coupled to any suitable transceiver circuitry that can enable device  100  to be communicatively coupled to another device (e.g., a host computer or an accessory device) and communicate with that other device wirelessly, or via a wired connection (e.g., using a connector port). Communications circuitry  114  may be configured to determine a geographical position of electronic device  100 . For example, communications circuitry  114  may utilize the global positioning system (“GPS”) or a regional or site-wide positioning system that may use cell tower positioning technology or Wi-Fi™ technology. 
     Processing circuitry  102  of electronic device  100  may include any processing circuitry that may be operative to control the operations and performance of one or more components of electronic device  100 . For example, processor  102  may receive input signals from any input component  108  and/or sensor circuitry  112  and/or communications circuitry  114  and/or drive output signals through any output component  110  and/or communications circuitry  114 . As shown in  FIG.  1   , processor  102  may be used to run at least one application  103 . Application  103  may include, but is not limited to, one or more operating system applications, firmware applications, software applications, algorithmic modules, media analysis applications, media playback applications, media editing applications, communications applications, pass applications, calendar applications, social media applications, state determination applications, biometric feature-processing applications, activity monitoring applications, activity motivating applications, and/or any other suitable applications. For example, processor  102  may load application  103  as a user interface program to determine how instructions or data received via an input component  108  and/or any other component of device  100  may manipulate the one or more ways in which information may be stored and/or provided to the user via an output component  110  and/or any other component of device  100 . Any application  103  may be accessed by any processing circuitry  102  from any suitable source, such as from memory  104  (e.g., via bus  115 ) and/or from another device or server (e.g., remote server  50 ) (e.g., via communications circuitry  114 ). Processor  102  may include a single processor or multiple processors. For example, processor  102  may include at least one “general purpose” microprocessor, a combination of general and special purpose microprocessors, instruction set processors, graphics processors, video processors, communications processors, motion processors, biometric processors, application processors, and/or related chips sets, and/or special purpose microprocessors. Processor  102  also may include on board memory for caching purposes. 
     Processor  102  may be configured to capture (e.g., with an input component  108 ) or otherwise access (e.g., from memory  104  and/or communications circuitry  114 ) and process any suitable library  105  of any suitable amount of media content pieces (e.g., any media content and/or associated metadata) for managing the media content pieces in an effective and user-friendly manner. Media content pieces (“MCPs”) may include any suitable type of asset or item of media content, such as image content (e.g., pixel values for one or more photographs or video frames) and/or audio content (e.g., one or more audio tracks that may or may not be associated with video frames as audio/visual video content) and/or text content (e.g., an E-book, etc.) and/or haptic content (e.g., vibrations or motions that may be provided in connection with other media, such as a video), where examples of different types of visual media content of an MCP may include, but are not limited to, a still photo, a video clip, a burst-mode photo sequence, a panoramic photo, a time lapse video, a slow motion video, a short video that may be captured alongside a photograph (e.g., a Live Photo™ available by Apple Inc.), and/or the like. An MCP may also include any suitable amount of any suitable type(s) of metadata assets or metadata content (metadata) that may describe one or more characteristics of and be associated with the media content (e.g., an image, a video, etc.) of the MCP, including, but not limited to, captured metadata, post-capture metadata, derived metadata, explicit user-assigned metadata, and/or the like. Additionally, processor  102  may be configured to generate or otherwise access (e.g., from memory  104  and/or communications circuitry  114 ) an MCP management system  107  (e.g., a database (e.g., a relational database (e.g., a tabular database, etc.), a distributed database that can be dispersed or replicated among different points in a network, an object-oriented programming database that can be congruent with the data defined in object classes and subclasses, etc.) and/or a knowledge graph metadata network) that may be operative to be used by processor  102  (e.g., along with or as a portion of any suitable application  103 ) to manage, store, ingest, organize, and/or retrieve the various MCPs of library  105 . In some examples where device  100  may collect and/or process a relatively large MCP library  105  and/or use relatively large MCP management systems  107 , device  100  may not have enough memory capacity to collect and process and store all of the data for such a library and/or management system and can instead be configured to offload some or all of the data on an external device that may be remote from device  100  (e.g., server  50 , which, although not shown, may be configured to include, one, some, each, and/or multiple ones of the components of device  100 ). The external device can be configured to communicate with a plurality of devices  100 , and store data collected from these devices. The external device can be further configured to execute computer instructions on the data and communicate the result with one or more of these devices  100 . 
     Electronic device  100  may also be provided with a housing  101  that may at least partially enclose one or more of the components of device  100  for protection from debris and other degrading forces external to device  100 . In some embodiments, one or more of the components may be provided within its own housing (e.g., input component  108  may be an independent keyboard or mouse within its own housing that may wirelessly or through a wire communicate with processor  102 , which may be provided within its own housing). 
     As shown in  FIG.  2   , one specific example of electronic device  100  may be an electronic device, such as an iPhone™, where housing  101  may allow access to various input components  108   a - 108   i , various output components  110   a - 110   c , and various I/O components  109   a - 109   c  through which device  100  and a user and/or an ambient environment may interface with each other. Input component  108   a  may include a button that, when pressed, may cause a “home” screen or menu of a currently running application to be displayed by device  100 . Input component  108   b  may be a button for toggling electronic device  100  between a sleep mode and a wake mode or between any other suitable modes. Input component  108   c  may include a two-position slider that may disable one or more output components  112  in certain modes of electronic device  100 . Input components  108   d  and  108   e  may include buttons for increasing and decreasing the volume output or any other characteristic output of an output component  110  of electronic device  100 . Each one of input components  108   a - 108   e  may be a mechanical input component, such as a button supported by a dome switch, a sliding switch, a control pad, a key, a knob, a scroll wheel, or any other suitable form. 
     An output component  110   a  may be a display that can be used to display a visual or graphic user interface (“GUI”)  180 , which may allow a user to interact with electronic device  100 . GUI  180  may include various layers, windows, screens, templates, elements, menus, and/or other components of a currently running application (e.g., application  103 ) that may be displayed in all or some of the areas of display output component  110   a . One or more of user input components  108   a - 108   i  may be used to navigate through GUI  180 . For example, one user input component  108  may include a scroll wheel that may allow a user to select one or more graphical elements or icons  182  of GUI  180 . Icons  182  may also be selected via a touch screen I/O component  109   a  that may include display output component  110   a  and an associated touch input component  108   f . Such a touch screen I/O component  109   a  may employ any suitable type of touch screen input technology, such as, but not limited to, resistive, capacitive, infrared, surface acoustic wave, electromagnetic, or near field imaging. Furthermore, touch screen I/O component  109   a  may employ single point or multi-point (e.g., multi-touch) input sensing. 
     Icons  182  may represent various applications, layers, windows, screens, templates, elements, and/or other components that may be displayed in some or all of the areas of display component  110   a  upon selection by the user. Furthermore, selection of a specific icon  182  may lead to a hierarchical navigation process. For example, selection of a specific icon  182  may lead from screen  190  of  FIG.  2    to a new screen of GUI  180  that may include one or more additional icons or other GUI elements of the same application or of a new application associated with that icon  182 . Textual indicators  181  may be displayed on or near each icon  182  to facilitate user interpretation of each graphical element icon  182 . It is to be appreciated that GUI  180  may include various components arranged in hierarchical and/or non-hierarchical structures. When a specific icon  182  is selected, device  100  may be configured to open a new application associated with that icon  182  and display a corresponding screen of GUI  180  associated with that application. For example, when the specific icon labeled with a “Photos” textual indicator is selected, device  100  may launch or otherwise access a media management and editing application (e.g., Photos™ available by Apple Inc.) that may provide user access to one or more collections of MCPs (e.g., photos and/or videos) and may display screens of a specific user interface that may include one or more tools or features for interacting with media content. As another example, when the specific icon labeled with a “Calendar” textual indicator is selected, device  100  may launch or otherwise access a specific calendar or reminder application and may display screens of a specific user interface that may include one or more tools or features for interacting with one or more events or other reminders that may be time-sensitive in a specific manner. As another example, when the specific icon labeled with a “Wallet” textual indicator is selected, device  100  may launch or otherwise access a specific pass or wallet application and may display screens of a specific user interface that may include one or more tools or features for interacting with one or more passes or other credentials (e.g., payment credentials of an NFC component) in a specific manner. As another example, when the specific icon labeled with a “Contacts” textual indicator is selected, device  100  may launch or otherwise access a specific contacts or address book application and may display screens of a specific user interface that may include one or more tools or features for interacting with one or more contacts of one or more persons or businesses or other entities in a specific manner. As another example, when the specific icon labeled with a “Social Media” textual indicator is selected, device  100  may launch or otherwise access a specific social media application or site and may display screens of a specific user interface that may include one or more tools or features for interacting with one or more social media networks with which a user may or may not have an account in a specific manner. As another example, when the specific icon labeled with a “Weather” textual indicator is selected, device  100  may launch or otherwise access a specific weather application or site and may display screens of a specific user interface that may include one or more tools or features for determining or presenting the current and/or past and/or future weather and/or other environmental conditions local to and/or distant from device  100  in a specific manner (e.g., as may be detected by any suitable sensors of device  100  and/or of remote server  50 ). As another example, when the specific icon labeled with a “Health” textual indicator is selected, device  100  may launch or otherwise access a specific health application or site and may display screens of a specific user interface that may include one or more tools or features for determining or presenting the current and/or past health activities and/or biometric characteristics of a user (e.g., as may be detected by any suitable sensors of device  100  and/or of remote server  50 ) in a specific manner. For each application, screens may be displayed on display output component  110   a  and may include various user interface elements. Additionally or alternatively, for each application, various other types of non-visual information may be provided to a user via various other output components  110  of device  100 . 
     Electronic device  100  also may include various other I/O components  109  that may allow for communication between device  100  and other devices, such as a connection port  109   b  that may be configured for transmitting and receiving data files, such as media files or customer order files, and/or any suitable information (e.g., audio signals) from a remote data source and/or power from an external power source. For example, I/O component  109   b  may be any suitable port (e.g., a Lightning™ connector or a 30-pin dock connector available by Apple Inc.). I/O component  109   c  may be a connection slot for receiving a SIM card or any other type of removable component. Electronic device  100  may also include at least one audio input component  110   g , such as a microphone, and at least one audio output component  110   b , such as an audio speaker. Electronic device  100  may also include at least one tactile output component  110   c  (e.g., a rumbler, vibrator, haptic and/or taptic component, etc.), a camera and/or scanner input component  108   h  (e.g., a video or still camera, and/or a bar code scanner or any other suitable scanner that may obtain product identifying information from a code, such as a bar code, or the like), and a biometric input component  108   i  (e.g., a fingerprint reader or other feature recognition sensor, which may operate in conjunction with a feature-processing application that may be accessible to electronic device  100  for authenticating a user). 
       FIG.  3    is an illustrative schematic of MCP library  105 , which may include any suitable number of MCPs  305  of any suitable type. Library  105  may at least partially reside on device  100  (e.g., in memory  104 ) and/or may at least partially reside on a remote server (e.g., server  50 ) that may be accessible to device  100 . As shown in  FIG.  3   , for example, at least one, some, or each MCP  305  may include an asset or item of MCP media content or an MCP media content item (“MCI”)  310  (e.g., an image, a video, etc.) and associated MCP metadata content  311 . MCP metadata content  311  may include any suitable number of metadata assets of any suitable type(s) of metadata, including, but not limited to, captured metadata  315  and post-capture metadata  320 . Captured metadata  315  may include any suitable metadata that may be generated by or associated with characteristics of the capture device that captured the associated media content  310  (e.g., by camera input component  108   h  and/or any other suitable component(s) of device  100  or by any suitable component(s) of any other suitable media capture device (e.g., server  50 )) at the time that such media content is captured. Examples of capture metadata  315  may include, but are not limited to, date and time of media content capture (e.g., based on a clock of device  100 ), location of media content capture (e.g., based on GPS or any other location service of device  100 ), one or media capture device settings of media content capture (e.g., any suitable settings of camera input component  108   h , such as exposure, flash, white point, etc.), and/or the like. 
     Post-capture metadata  320  may include any suitable type(s) of metadata that may be defined for the media content after the media content has been capture. As shown, for example, two exemplary types of post-capture metadata  320  may include derived metadata  325  and explicit user-assigned metadata  330 . Explicit user-assigned metadata  330  may include any suitable keywords (e.g., birthday, vacation, anniversary, etc.) or other suitable tags (e.g., like, dislike, favorite, verification of identity of one or more content indicators (e.g., faces or locations or scenes or clusters of features or indicators or otherwise) in the media content, etc.) that a user may assign to or otherwise associate with the media content and/or one or more user-specified associations for the MCP with respect to other MCPs (e.g., inclusion of the MCP in a user-specified album (e.g., photo album) or other collection type of MCPs). Such user-assignment of any suitable user-assigned metadata  330  may be accomplished via any suitable user interface application that may be presented by device  100  and/or server  50  to a user of system  1 . 
     Derived metadata  325  of an MCP  305  may include any suitable types of metadata assets that may be derived or inferred by processor analysis (e.g., by an application  103  of processor  102 ) of media content  310 , captured metadata  315 , user-assigned metadata  330 , and/or any user actions that may be associated with that MCP  305 . One or more framework services (e.g., service(s) of device  100  and/or of server  50 ) may analyze one or more MCPs  305 , their media content, their metadata, and/or any associated user actions to produce derived metadata  325  for one or more of the MCPs. Examples of such derived metadata  325  may include, but are not limited to, derived domain metadata  332 , media content-analysis metadata  335  (e.g., image-analysis metadata for an image MCI  310 ), and/or implicit user metadata  340 . Implicit user metadata  340  may be any suitable metadata that may be generated by monitoring any user actions with respect to the MCP (e.g., sharing the MCP with others, repeatedly viewing the MCP, etc.). 
     Media content-analysis metadata  335  may include any suitable type(s) of metadata attributes that may be determined by analyzing MCP media content  310 . In some embodiments, such media content-analysis metadata  335  may include any suitable media attribute score metadata  345  and/or any suitable media content indicator metadata  350 . Examples of media attribute score metadata  345  may include, but are not limited to, any suitable media attribute scores for quantifying focus, exposure, blur, sharpness, color attributes, pixel characteristics, pixel intensity values, luminance values, brightness values, and/or the like for any image MCI and/or for any frame(s) of any video MCI, and/or for quantifying volume, pitch, timbre, voice, source (e.g., detected sound is human voice, detected sound is fire truck, etc.) and/or the like for any audio MCI and/or the like for any other type of MCI. Media attribute score metadata  345  may be generated and/or otherwise obtained by one or more suitable services (e.g., framework services) of system  1  (e.g., of device  100  and/or of server  50 ). Examples of media content indicator metadata  350  may include, but are not limited to, any suitable media content indicators that may be indicative of the type of its associated MCI  310  and/or that may characterize its associated MCI  310  in any suitable manner. In an example when an MCI  310  is an image, one or more media content indicators of associated media content indicator metadata  350  may reference one or more types of particular content indicators that may be valid for that image. Additionally or alternatively, when an MCI  310  may be a video clip with multiple frames or images, one or more media content indicators of associated media content indicator metadata  350  may be expressed in terms of ranges that may define the range of images or frames over which a particular content indicator may be valid. Examples of particular types of content indicators of media content indicator metadata  350  may include, but are not limited to, face indicators (e.g., unique face vectors (or any other suitable statistical representations)), smile indicators, voice indicators, camera motion indicators, junk content indicators, scene indicators, image quality indicators, and/or the like. Any such content indicators  350  may be generated or obtained (e.g., as one or more feature vectors or feature indicators) by one or more suitable services (e.g., framework services) of system  1  (e.g., of device  100  and/or of server  50 ). 
     Derived domain metadata  332  may include any suitable data associated with any suitable domain type(s) that may be associated with the MCP by analyzing the metadata already associated with the MCP. For example, in some embodiments, a domain type may be a location domain and any captured location metadata of captured metadata  315 , explicit user metadata  330 , media content-analysis metadata  335  (e.g., media attribute score(s)  345  and/or content indicator(s)  350 ), and/or implicit user metadata  340  and/or other derived metadata  325  for any MCP or collection of MCPs may be analyzed with or without any contextual data in order to associate an MCP with any suitable derived location metadata  332  that may be indicative of one or more location regions and/or one or more location areas (e.g., areas of interest) and/or one or more location designations (e.g., home, residence, office, etc.) and/or the like that may enable the MCP to be grouped with other MCPs. As another example, a domain type may be a time domain and any captured time metadata of captured metadata  315 , explicit user metadata  330 , media content-analysis metadata  335  (e.g., media attribute score(s)  345  and/or content indicator(s)  350 ), and/or implicit user metadata  340  and/or other derived metadata  325  for any MCP or collection of MCPs may be analyzed with or without any contextual data in order to associate an MCP with any suitable derived time metadata  332  that may be indicative of one or more time quantifications (e.g., weekday, season, etc.) and/or one or more time event designations (e.g., holiday, Halloween, etc.) and/or the like that may enable the MCP to be grouped with other MCPs. As another example, a domain type may be a person domain and any captured person metadata of captured metadata  315 , explicit user metadata  330 , media content-analysis metadata  335  (e.g., media attribute score(s)  345  and/or content indicator(s)  350 ), and/or implicit user metadata  340  and/or other derived metadata  325  for any MCP or collection of MCPs may be analyzed with or without any contextual data in order to associate an MCP with any suitable derived person metadata  332  that may be indicative of one or more person quantifications (e.g., person names and/or person relationships, such as John Doe (“user”), Jane Doe (“user&#39;s wife”), Jenn Doe (“user&#39;s daughter”), unverified person (unknown relationship), Jim James (“user&#39;s co-worker”), etc.) and/or one or more person event designations (e.g., anniversary, birthday, etc.) and/or one or more person social group designations (e.g., co-worker social group of John Doe and Jim James, any social group collection of identities that may be identified to appear together often (e.g., in different moments, at different events, etc.), etc.) and/or the like that may enable the MCP to be grouped with other MCPs. As another example, a domain type may be a place domain and any captured place metadata of captured metadata  315 , explicit user metadata  330 , media content-analysis metadata  335  (e.g., media attribute score(s)  345  and/or content indicator(s)  350 ), and/or implicit user metadata  340  and/or other derived metadata  325  for any MCP or collection of MCPs may be analyzed with or without any contextual data in order to associate an MCP with any suitable derived place metadata  332  that may be indicative of one or more points of interest (“POIs”) and/or regions of interest (“ROIs”) (e.g., nature, water, mountain, urban, beach, nightlife, restaurant, entertainment, park, culture, travel, shopping, etc.) and/or the like that may enable the MCP to be grouped with other MCPs. As another example, a domain type may be a scene domain and any captured scene metadata of captured metadata  315 , explicit user metadata  330 , media content-analysis metadata  335  (e.g., media attribute score(s)  345  and/or content indicator(s)  350 ), and/or implicit user metadata  340  and/or other derived metadata  325  for any MCP or collection of MCPs may be analyzed with or without any contextual data in order to associate an MCP with any suitable derived scene metadata  332  that may be indicative of one or more scenes (e.g., animal (e.g., bird, reptile, dog, fish, etc.), outdoor (e.g., sky, sand, playground, etc.), celebration (e.g., wedding, birthday cake, jack-o-lantern, etc.), structure (e.g., fireplace, aquarium, etc.), vehicle (e.g., helicopter, bicycle, limousine, etc.), recreation (e.g., performance (e.g., orchestra, karaoke, rodeo, etc.), sport (e.g., rafting, surfing, scuba, etc.), etc.), plant (e.g., flower, tree, etc.), game (e.g., poker, foosball, etc.), fire, liquid (e.g., jacuzzi, river, etc.), art (e.g., origami, balloon, etc.), light (e.g., chandelier, candle, etc.), room (e.g., bar, museum, restaurant, etc.), people, etc.) and/or the like that may enable the MCP to be grouped with other MCPs. As another example, a domain type may be a moment domain and any captured moment metadata of captured metadata  315 , explicit user metadata  330 , media content-analysis metadata  335  (e.g., media attribute score(s)  345  and/or content indicator(s)  350 ), and/or implicit user metadata  340  and/or other derived metadata  325  for any MCP or collection of MCPs may be analyzed with or without any contextual data in order to associate an MCP with any suitable derived moment metadata  332  that may be indicative of a moment (e.g., a distinct range of times and a distinct location or distinct range of locations) and/or the like that may enable the MCP to be grouped with other MCPs. As described in more detail with respect to  FIG.  4   , for example, one or more applications or services (e.g., a framework services) of system  1  (e.g., of processor  102  and/or server  50 ) may be operative to generate and/or use an MCP management system  107  (e.g., a database and/or a knowledge graph metadata network (e.g., a hierarchical directed acyclic graph (“DAG”) structure that may include nodes corresponding to different domain types and different specific sub-domains of each domain type of metadata  311 , for example, where derived domain metadata  332  may be defined in terms of node identifiers in the graph structure, and all nodes of the structure may be correlated (e.g., by correlation weights (e.g., confidence weights and/or relevance weights))) to manage, store, ingest, organize, and/or retrieve the various MCPs  305  (e.g., metadata  311  and/or content  310 ) of library  105 . Additional disclosure regarding suitable graph metadata networks can be found in co-pending, commonly-assigned U.S. Patent Application Publication No. 2017/0091154 (published on Mar. 30, 2017) and in co-pending, commonly-assigned U.S. patent application Ser. No. 15/391,269 (filed on Dec. 27, 2016), each of which is hereby incorporated by reference herein in its entirety. 
     Therefore, there may be various types of metadata assets  311  that may be associated with an MCI  310  of an MCP  305 . A particular type of metadata asset may be a first metadata asset  311  of a first MCP  305  associated with a first MCI  310  and may also be a second metadata asset  311  of a second MCP  305  associated with a second MCI  310 . In some embodiments, a type of metadata may be categorized as primitive metadata or inferred metadata, which may be determined based at least on primitive metadata. For example, as may be used herein, “primary primitive metadata” may refer to metadata that may describe one or more characteristics or attributes associated with one or more MCIs  310 . Some types of primary primitive metadata include, but are not limited to, one or more of time metadata, geo-position metadata, geolocation metadata, people metadata, scene metadata, content metadata, object metadata, and/or sound metadata. Time metadata may refer to a time that may be associated with one or more media content items (e.g., a timestamp associated with a media content item, a time at which the media content item was captured or otherwise generated, a time at which the media content item was modified, a time at which the media content item was stored, a time at which the media content item was transmitted, a time at which the media content item was received, etc.), which may be captured metadata  315 . Geo-position metadata may refer to geographic and/or spatial attributes that may be associated with one or more media content items using any suitable location sensing and/or geographic coordinate system (e.g., latitude, longitude, and/or altitude, etc.), which may be captured metadata  315 . Geolocation metadata may refer to one or more meaningful locations rather than geographic coordinates that may be associated with one or more media content items, such as a beach (and its name), a street address, a country name, a region, a building, a landmark, and/or the like, which, for example, may be determined by processing geo-position metadata together with data from a map application and/or any other suitable data available to device  100  to determine that the geolocation for a scene in a group of images. People metadata may refer to at least one face that may be detected in at least one media content item (e.g., through any suitable facial recognition technique(s)), where the people metadata may be indicative of a particular identity (e.g., a tagged or otherwise known (e.g., verified) person) or an unknown identity (e.g., an unverified or unknown person), which may be metadata  330  and/or metadata  335 . Scene metadata and/or object metadata may refer to an overall description of an activity or situation associated with one or more media content items based on any objects that may be detected therein (e.g., if a media content item includes a group of images, then scene metadata for the group of images may be determined using detected objects in one or more of the images (e.g., the detection of a large cake with candles and/or balloons in at least two images in the group can be used to associate “birthday” scene metadata with each of the images)), where such objects or scene indicators or content indicators may be any suitable objects (e.g., a detected animal, a detected company logo, a detected piece of furniture, a detected instrument, etc.) that may be able to be detected in a media content item using any suitable techniques (e.g., any suitable image processing techniques), which may be metadata  350 . Content metadata may refer to any features of a media content item (e.g., pixel characteristics, pixel intensity values, luminance values, brightness values, loudness levels, etc., etc.), which may be metadata  345 . Sound metadata may refer to one or more detected sounds associated with one or more media content items a detected sound as a human&#39;s voice, a detected sound as a fire truck&#39;s siren, etc.), which may be metadata  335 . 
     As used herein, “inferred metadata” may refer to metadata that may describe one or more characteristics or attributes associated with one or more MCIs  310  that is beyond the information that may be provided by primitive metadata. One difference between primitive metadata and inferred metadata may be that primitive metadata may represent an initial set of descriptions of one or more media content items while inferred metadata may provide one or more additional descriptions or characteristics of the one or more media content items based on processing one or more of the primitive metadata assets (e.g., in combination with any suitable contextual data that may be available to device  100 ). For example, primitive metadata may identify two detected persons in one or a group of images as John Doe and Jane Doe, while inferred metadata may identify John Doe and Jane Doe as a married couple based on processing at least a portion of the primitive metadata (e.g., in combination with any suitable contextual data). Inferred metadata may be determined from at least one of (i) processing of a combination of different types of primary primitive metadata, (ii) processing of a combination of different types of contextual information, and (iii) processing of a combination of primary primitive metadata and contextual information. As used herein, “context” and/or its variations may refer to any or all data that may be accessible to device  100 , such as physical, logical, social, and/or other contextual information. As used herein, “contextual information” and/or contextual data and/or contextual metadata and/or its variations may refer to metadata or any other suitable information that may describe or define a user&#39;s context or a context of a user&#39;s device (e.g., device  100  with access to library  105  (e.g., as may be associated with a user)). Exemplary contextual information may include, but is not limited to, a predetermined time interval, a time event scheduled to occur in a predetermined time interval, a geolocation to be visited in a predetermined time interval, one or more identified persons associated with a predetermined time, an event scheduled for a predetermined time, a geolocation to be visited at predetermined time, weather metadata describing weather associated with a particular period in time (e.g., rain, snow, sun, temperature, etc.), season metadata describing a season associated with capture of a media content item, and/or the like. For example, such contextual information can be obtained from any suitable application data local to device  100  and/or any suitable application data that may be provided by external sources (e.g., a remote server (e.g., server  50  (e.g., via the internet))) from any suitable application or data source, such as a social networking application (e.g., information indicative of relationships between people, planned events with or without known attendees, birthdays, favorite interests (e.g., hobbies, activities, etc.) and/or restaurants and/or media, etc.), a weather application (e.g., information indicative of weather or other environmental conditions at a certain place at a certain time), a calendar application (e.g., information indicative of a scheduled event, scheduled participants, etc.), a contact application (e.g., information indicative of a person&#39;s home address, etc.), a health application (e.g., information indicative of a user&#39;s heart rate, steps taken, speed, calories burned, food ingested, particular sport, or hobby performed, etc.), a wallet application (e.g., information indicative of a scheduled or attended event, passes for an event, receipts for services and/or goods purchased, etc.), a messaging application or an e-mail application (e.g., information indicative of discussed events, communicating persons, etc.), a map application (e.g., information indicative of places visited, etc.), a photos application itself (e.g., information indicative of any tags or verified face identifications, likes, shares, groupings, albums, and/or the like based on a user&#39;s interaction (e.g., input data) with library  105 ), and/or any other type of application or data source that may be operative to provide information that may be processed (e.g., based on and/or in combination with any known metadata of library  105 ) to reveal additional characteristics to be associated with one or more media content items (e.g., as new metadata and/or correlations between known metadata (e.g., to define a new node and/or correlation between nodes of a metadata network (e.g., a knowledge graph)), as described in more detail with respect to  FIG.  4   ). Therefore, one or metadata assets of library  105  may be indicative of a person&#39;s name, birthplace, birthday, gender, relationship status, identification of related persons, social groups and identities of members of social groups of any type (e.g., family, friends, co-workers, etc.), current and/or prior address(es) of residence and/or vacation and/or work, interests (e.g., hobbies (e.g., pets owned, instruments played, activities enjoyed, restaurants enjoyed, etc.)), places of interest (e.g., visited and/or interested in), etc.), religion, trips taken and associated travelers, events attended and associated attendees, physical activity (e.g., workouts or sports or hobbies or activities performed or enjoyed), and/or the like. The preceding examples are illustrative and not restrictive. 
     Two categories of inferred metadata may be referred to herein as primary inferred metadata and auxiliary inferred metadata. Primary inferred metadata may include time event metadata that may describe one or more time events associated with one or more media content items. For example, if a media content item or a collection of media content items is associated with primary primitive metadata indicative of a particular time or a particular range of times and/or a particular location, then associated primary inferred metadata may be determined to include time event metadata that may describe one or more time events or people events associated with such time and/or location information (e.g., a vacation, a birthday, a sporting event, a concert, a graduation ceremony, a dinner, a project, a work-out session, a traditional holiday, etc.), where such primary inferred metadata may, in some embodiments, be determined by analyzing such primary primitive metadata alone or in combination with any suitable contextual metadata (e.g., calendar data and/or social media data, etc.). Auxiliary inferred metadata may be any suitable metadata including, but not limited to, geolocation relationship metadata, person relationship metadata, object relationship metadata, and sound relationship metadata. Geolocation relationship metadata may refer to a relationship between one or more known persons associated with one or more media content items and one or more locations associated with the one or more media content items. For example, an analytics engine or data mining technique can be used to determine that a scene associated with one or more media content items of John Doe represents John Doe&#39;s home. Person relationship metadata may refer to a relationship between one or more known persons associated with one or more media content items and one or more other known persons associated with the one or more media content items. For example, an analytics engine or data mining technique can be used to determine that Jane Doe (who appears in one or more images with John Doe) is John Doe&#39;s wife. Object relationship metadata may refer to a relationship between one or more known persons associated with one or more media content items and one or more known objects associated with the one or more media content items. For example, an analytics engine or data mining technique can be used to determine that a boat appearing in one or more images with John Doe is owned by John Doe. Sound relationship metadata may refer to a relationship between one or more known sounds associated with one or more media content items and one or more known persons associated with the one or more media content items. For example, an analytics engine or data mining technique can be used to determine that a voice that appears in one or more videos with John Doe is John Doe&#39;s voice. 
     Inferred metadata may be determined or inferred from primitive metadata and/or contextual information by performing any suitable type(s) of processing, including, but not limited to, data mining primitive metadata and/or contextual information; analyzing primitive metadata and/or contextual information, applying logical rules to primitive metadata and/or to contextual information, and/or any other known methods that may be used to infer new information from provided or acquired information. In some embodiments, primitive metadata can be extracted from inferred metadata. For example, primary primitive metadata (e.g., time metadata, geolocation metadata, scene metadata, etc.) can be extracted from primary inferred metadata (e.g., time event metadata, etc.). Techniques for determining inferred metadata and/or extracting primitive metadata from inferred metadata can be iterative. For example, inferring metadata can trigger the inference of other metadata and so on. As another example, extracting primitive metadata from inferred metadata can trigger inference of additional inferred metadata or extraction of additional primitive metadata. 
       FIG.  4    shows, in block diagram form, an exemplary portion  107   n  of a type of MCP management system  107 , which may be provided by any suitable graph structure, such as a DAG structure or otherwise, and may also be referred to herein as a knowledge graph metadata network or knowledge graph or metadata network  107   n . While an MCP management system may, alternatively, be provided by any suitable database (e.g., a relational database, a distributed database, an object-oriented programming database, etc.), using such a database for management of a library of MCPs may be too resource-intensive (e.g., substantial computational resources may be needed to manage the MCPs (e.g., substantial processing power may be needed for performing queries or transactions, storage memory space for storing the necessary databases, etc.)) and/or may not be as easily implemented on a computing system with limited storage capacity (e.g., device  100 ), thereby requiring certain functionality of a remote subsystem (e.g., remote server  50 ). Instead, in some embodiments, MCP management system  107  may be at least partially provided as a metadata network  107   n , at least an exemplary portion of which may be shown in  FIG.  4   , that may include correlated metadata assets that may describe characteristics associated with various MCIs  310  of MCPs  305  of library  105 , where such a metadata network may be operative to manage library  105  locally on device  100  (e.g., with processing circuitry  102 ) without the need for any external data sources (e.g., remote server  50 ). Each metadata asset may be a type of metadata  311  that may be associated with and that may describe or otherwise be indicative of at least characteristic of one or more MCIs  310  of one or more MCPs  305  of library  105 . As a non-limiting example, a metadata asset can describe a characteristic associated with multiple MCIs  310  (e.g., a metadata asset may be metadata  311  of two or more different MCPs  305 ) in library  105 . Each metadata asset can be represented as a node in metadata network  107   n . A metadata asset can be correlated with at least one other metadata asset. Each correlation between metadata assets can be represented as an edge in the metadata network that is between the nodes representing the correlated metadata assets. 
     Device  100  (e.g., processing circuitry  102 ) may include any suitable processing unit(s), such as one or more central processing units (“CPUs”), one or more graphics processing units (“GPUs”), other integrated circuits (“ICs”), memory, and/or other electronic circuitry. Such processing unit(s) may include any suitable MCP management logic/modules, which may be implemented as hardware (e.g., electronic circuitry associated with processing circuitry  102 , dedicated logic, etc.), software (e.g., one or more instructions associated with a computer program (e.g., application  103 ) that may be executed by processing circuitry  102 , software run on a general-purpose computer system or a dedicated machine, etc.), or a combination thereof, for generating and/or maintaining and/or otherwise operating MCP management system  107  by manipulating and/or otherwise processing any suitable data of library  105  and any other suitable data (e.g., contextual data) available to device  100  (e.g., social media application data, contact application data, weather application data, health application data, calendar application data, messaging application data, e-mail application data, and/or the like). Therefore, device  100  and/or any other portion(s) of system  1  (e.g., server  50 ) may be operative to generate and use a knowledge graph metadata network  107   n  as a multi-dimensional network, which may be a dynamically organized collection of metadata assets of metadata  311  of MCPs  305  of library  105  but which may not include any media content items  310  of such MCPs  305 , and/or which may be used for deductive reasoning. For example, device  100  may be operative to (i) generate metadata network  107   n , (ii) relate and/or present at least two MCIs  310  based on metadata network  107   n , (iii) determine and/or present interesting MCIs  310  of library  105  based on metadata network  107   n  and predetermined criterion, (iv) select and/or present representative MCIs  310  to summarize a collection (e.g., a moment) of media content items based on input specifying the representative group&#39;s size, (v) use metadata network  107   n  to reduce a number of unverified persons detected in media content  310 , (vi) use metadata network  107   n  to determine a mood of a collection (e.g., a moment) of media content items, and/or (vii) use metadata network  107   n  to define a collection of media content items for a relevant interest. 
     Metadata network  107   n  may enable deep connections between metadata using multiple dimensions in the metadata network, which can be traversed for additionally deduced correlations. Each dimension in the metadata network may be viewed as a grouping of metadata based on metadata type. For example, a grouping of metadata may be all time metadata assets in a metadata collection (e.g., all metadata  311  of library  105 ) and another grouping could be all geo-position metadata assets in the same metadata collection. Thus, in such an example, a time dimension may refer to all time metadata assets in the metadata collection and a geo-position dimension may refer to all geo-position metadata assets in the same metadata collection. Furthermore, the number of dimensions can vary based on constraints. Constraints may include, but are not limited to, a desired use for the metadata network, a desired level of detail, and/or the available metadata or computational resources that may be used to implement the metadata network. For example, the metadata network can include only a time dimension, the metadata network can include all types of primitive metadata dimensions, and/or the like. With regard to the desired level of detail, each dimension can be further refined based on specificity of the metadata. That is, each dimension in the metadata network may be a grouping of metadata based on metadata type and the granularity of information may be described by the metadata. For a first example, there may be two time dimensions in the metadata network, where a first time dimension may include all time metadata assets classified by week and a second time dimension may include all time metadata assets classified by month. For a second example, there may be two geolocation dimensions in the metadata network, where a first geolocation dimension may include all geolocation metadata assets classified by type of establishment (e.g., home, business, etc.) and a second geolocation dimension that may include all geolocation metadata assets classified by country. The preceding examples are merely illustrative and not restrictive. It is to be appreciated that the level of detail for dimensions can vary depending on designer choice, application, available metadata, and/or available computational resources. 
     Metadata network  107   n  may be a multi-dimensional network of MCP metadata  311 . As used herein, a “multi-dimensional network” and its variations may refer to a graph (e.g., a complex graph) having multiple kinds of relationships. A multi-dimensional network generally may include multiple nodes and edges, where, in some embodiments, the nodes may represent metadata and the edges may represent relationships or correlations between the metadata. Exemplary multi-dimensional networks include, but are not limited to, edge-labeled multigraphs, multipartite edge-labeled multigraphs, DAGs, and multilayer networks. In some embodiments, the nodes in metadata network  107   n  may represent metadata assets of MCP metadata  311 , for example, where each node may represent a particular metadata asset that may be associated with one or more MCIs  310  and MCPs  305  of library  105  (e.g., a first node may be a first metadata asset that may not only be a part of first metadata  311  associated with a first MCI  310  of a first MCP  305  of library  105  but that may also be a part of second metadata  311  associated with a second MCI  310  of a second MCP  305  of library  105 . As another example, each node may represent a metadata asset that may be associated with a group of MCIs in a collection. As used herein, a “metadata asset” and its variations may refer to metadata (e.g., a single instance of metadata, a group of multiple instances of metadata, etc.) that may describe one or more characteristics of one or more MCIs in a library. As such, there may be a primitive metadata asset, an inferred metadata asset, and/or the like. For a first example, a primary primitive metadata asset may refer to a time metadata asset describing a time interval between Jun. 1, 2016 and Jun. 3, 2016 when one or more MCIs may have been captured. For a second example, a primary primitive metadata asset may refer to a geo-position metadata asset that may describe one or more latitudes and/or longitudes where one or more MCIs may have been captured. For a third example, an inferred metadata asset may refer to a time event metadata asset that may describe a holiday of Halloween. 
     Metadata network  107   n  may be configured to include two types of nodes, such as moment nodes and non-moments nodes. As used herein, a “moment” may refer to a single event (e.g., as may be described by an event or moment metadata asset) that may be associated with one or more MCIs. For example, a moment may refer to a vacation in Paris, France that lasted between Jun. 1, 2016 and Jun. 9, 2016 or to a Halloween party on Halloween afternoon at a person&#39;s home. For this example, the moment can be used to identify one or more MCIs  310  (e.g., one image, a group of images, a video, a group of videos, a song, a group of songs, etc.) that may be associated with the vacation in Paris, France that lasted between Jun. 1, 2016 and Jun. 9, 2016 or that may be associated with the afternoon Halloween party at a person&#39;s home. As used herein, a “moment node” may refer to a node in a multi-dimensional network, such as metadata network  107   n , that may represent a moment. Thus, a moment node may refer to a metadata asset (e.g., a primary inferred metadata asset) that may represent a single event or moment that may be associated with one or more MCIs. As used herein, a “non-moment node” may refer to a node in a multi-dimensional, such as metadata network  107   n , that may not represent a moment. Thus, a non-moment node may refer to at least one of a primary primitive metadata asset associated with one or more MCIs or an inferred metadata asset associated with one or more MCIs that is not a moment (i.e., not a moment metadata asset). As used herein, an “event” and its variations may refer to a situation or an activity that may be occurring at one or more locations during a specific time interval. An event may include, but is not limited to, one or more of a gathering of one or more persons to perform an activity (e.g., a holiday, a vacation, a birthday, a dinner, a project, a work-out session, etc.), a sporting event (e.g., an athletic competition, etc.), a ceremony (e.g., a ritual of cultural significance that is performed on a special occasion, etc.), a meeting (e.g., a gathering of individuals engaged in some common interest, etc.), a festival (e.g., a gathering to celebrate some aspect in a community, etc.), a concert (e.g., an artistic performance, etc.), a media event (e.g., an event created for publicity, etc.), a party (e.g., a large social or recreational gathering, etc.), and/or the like. While network  107   n  may be described with respect to moment nodes and non-moment nodes such that all nodes may be related via a moment dimension (e.g., a time dimension, as each moment node may be associated with a discrete duration/range of time), network  107   n  may alternatively be described with respect to “visit” nodes and non-visit nodes such that all nodes may be related via a visit dimension (e.g., a location dimension, where each visit node may be associated with a discrete geographic location/range of locations, not beholden to any particular time frame), or with respect to any other type of nod/dimension(s) delineation. 
     Edges in metadata network  107   n  between nodes may represent relationships or correlations between the nodes. For example, system  1  may update metadata network  107   n  as new metadata  311  is obtained. System  1  may be configured to manage MCIs  310  of library  105  using metadata network  107   n , such as to relate multiple MCIs based on the correlations (e.g., the edges in metadata network  107   n ) between metadata assets associated with the MCIs (e.g., the nodes of metadata network  107   n ). For example, a first group of one or more MCIs  310  may be related to a second group of one or more MCIs based on the metadata assets that may be represented as moment nodes in metadata network  107   n . As another example, metadata network  107   n  may be used to identify and present or otherwise utilize interesting groups of one or more MCIs  310  in library  105  based on certain correlations (e.g., certain edges in metadata network  105 ) between metadata assets associated with the MCIs (e.g., the nodes in metadata network  107   n ) and any suitable predetermined criterion, where the interesting groups of MCIs may be selected based on moment nodes in metadata network  107   n  and such predetermined criterion may refer to any suitable contextual information. It is to be appreciated that metadata network  107   n  of  FIG.  4    is exemplary and that every node that can be generated by system  1  is not shown. For example, even though every possible node is not illustrated in  FIG.  4   , system  1  may be operative to generate a node to represent each metadata asset of library  105 . 
     In metadata network  107   n  of  FIG.  4   , nodes representing metadata may be illustrated as boxes while edges representing correlations between metadata may be illustrated as labeled connections between boxes. Furthermore, moment nodes (e.g., a first moment node  402 , a second moment node  404 , and a third moment node  470 ) may be represented as boxes with thickened boundaries while other non-moment nodes (e.g., nodes  406 - 468 ) may lack such thickened boundaries. System  1  (e.g., processing circuitry  102 ) may be operative to define nodes based on metadata  311  associated with MCIs  310  of MCPs  305  of library  105 , and, as additional metadata  311  is determined (e.g., as new metadata is captured, assigned, inferred, derived, and/or the like (e.g., as additional MCIs  310  are captured or added to library  105  and/or as additional explicit user actions are taken and/or as additional contextual data is made available to system  1 ), additional nodes and/or edges may be generated and added to metadata network  107   n.    
     As shown, metadata network  107   n  may include a first moment metadata asset node  402  and a second moment metadata asset node  404 . Any moment node may be generated for a particular moment that may be identified by system  1  based on library  105  in any suitable manner. For example, when at least a threshold amount of MCIs  310  are identified to be associated with time metadata within a particular time range and with location metadata within a particular location range, then those identified MCIs  310  may be associated with a moment metadata asset that is descriptive of that time range and location range (e.g., a moment that may be indicative of an interesting event that took place during that time range at that location(s) due to at least a threshold amount of MCIs being captured). Alternatively, a particular subset of MCIs  310  of library  105  may be associated with a particular moment metadata asset in any other suitable manner. As just one particular example, which may be referred to herein with respect to metadata network  107   n  of  FIG.  4   , first moment metadata asset node  402  may be defined to represent first moment metadata indicative of a first moment that may be based on a particular time range of 2:00 PM to 4:00 PM on Oct. 31, 2009 and for a particular location range (e.g., within 100 feet) of a particular geographic coordinate (e.g., a particular address), such as a user&#39;s home at 22 Skyline Drive in Wellesley, Mass.,  02482 , U.S.A., where such a first moment may be defined as a result of at least a certain number of MCIs  310  being identified in library  105  that are associated with time metadata  311  indicative of any time within that time range and with location metadata  311  indicative of any location within that location range (e.g., when many MCIs are captured at a Halloween party at a person&#39;s home), while second moment metadata asset node  404  may be defined to represent second moment metadata indicative of a second moment that may be based on a particular time range of Jun. 30, 2016 through Jul. 1, 2016 and for a particular location range (e.g., within the city limits of a particular city), such as within New York City, N.Y., U.S.A., where such a second moment may be defined as a result of at least a certain number of MCIs  310  being identified in library  105  that are associated with time metadata  311  indicative of any time within that time range and with location metadata  311  indicative of any location within that location range (e.g., when many MCIs are captured during a vacation to New York City), where each one of such MCIs associated with second moment  404  may be different than each one of such MCIs associated with first moment  402 . Although only two moment nodes may be shown in  FIG.  4   , network  107   n  may include more than two moment nodes, each associated with a particular moment of a particular time range and a particular geographic range. Two moment nodes may be correlated by advancement of time (e.g., second moment metadata asset node  404  associated with the year 2016 may be after first moment metadata asset node  402  associated with the year 2009, as may be shown by the edge labelled “Next” between nodes  402  and  404 ). 
     Any suitable nodes may be associated with any suitable metadata assets and may be defined within network  107   n  and correlated with one or more moment nodes and/or one or more non-moment nodes. As shown, first moment metadata asset node  402  may be correlated (e.g., by date) with at least one time date metadata asset node  406  that may be defined to represent time date metadata indicative of a first date (e.g., Oct. 31, 2009) and/or may be correlated (e.g., by address) with at least one location address metadata asset node  408  that may be defined to represent location address metadata indicative of a first address (e.g., 22 Skyline Drive, Wellesley, Mass.,  02482 , U.S.A. or an associated geographic coordinate system (e.g., latitude, longitude, and/or altitude)). At least one MCI  310  of library  105  may be associated with first moment metadata represented by moment node  402  and time metadata represented by time node  406  and location metadata represented by location node  408 . As shown, time date metadata asset node  406  (e.g., indicative of Oct. 31, 2009) may be correlated (e.g., by season) with a time season metadata asset node  410  that may be defined to represent time season metadata indicative of a first season (e.g., Fall) and/or may be correlated (e.g., by year) with a time year metadata asset node  412  that may be defined to represent time year metadata indicative of a first year (e.g.,  2009 ) and/or may be correlated (e.g., by month) with a time month metadata asset node  414  that may be defined to represent time month metadata indicative of a first month (e.g., October) and/or may be correlated (e.g., by day) with a time day metadata asset node  416  that may be defined to represent time day metadata indicative of a first day (e.g.,  31 ) and/or may be correlated (e.g., by holiday) with a time holiday metadata asset node  418  that may be defined to represent time holiday metadata indicative of a first holiday (e.g., Halloween), and, although not shown, it is to be understood that time date metadata asset node  406  may be correlated with any other suitable types of metadata asset nodes within network  107   n , including, but not limited to, a time day of week metadata asset node that may be defined to represent time day of week metadata indicative of a day of week (e.g., Saturday) and/or the like. Additionally or alternatively, as shown, location address metadata asset node  408  (e.g., indicative of 22 Skyline Drive, Wellesley, Mass.,  02482 , U.S.A.) may be correlated (e.g., by city) with a location city metadata asset node  420  that may be defined to represent location city metadata indicative of a first city (e.g., Wellesley), which may be correlated (e.g., by state) with a location state metadata asset node  422  that may be defined to represent location state metadata indicative of a first state (e.g., Massachusetts), which may be correlated (e.g., by country) with a location country metadata asset node  424  that may be defined to represent location country metadata indicative of a first country (e.g., United States of America), and, although not shown, it is to be understood that location address metadata asset node  408  may be correlated (e.g., directly or via another node) with any other suitable types of metadata asset nodes within network  107   n , including, but not limited to, a location ZIP code metadata asset node that may be defined to represent location ZIP code metadata indicative of a ZIP code and/or the like. 
     Additionally or alternatively, as shown, first moment metadata asset node  402  may be correlated (e.g., by presence) with at least one person identity metadata asset node, such as a person identity metadata asset node  426  that may be defined to represent person identity metadata indicative of a first identity (e.g., John Doe) and/or a person identity metadata asset node  428  that may be defined to represent person identity metadata indicative of a second identity (e.g., Jane Doe) and/or a person identity metadata asset node  430  that may be defined to represent person identity metadata indicative of a third identity (e.g., a first unknown person), while person identity metadata asset node  428  may be correlated (e.g., by spouse) with person identity metadata asset node  426  (e.g., when the first identity (e.g., John Doe) and the second identity (e.g., Jane Doe) are determined to be each other&#39;s spouse). At least one MCI  310  of library  105  may be associated with first moment metadata represented by moment node  402  and person metadata represented by person node  426 , at least one MCI  310  of library  105  may be associated with first moment metadata represented by moment node  402  and person metadata represented by person node  428 , and at least one MCI  310  of library  105  may be associated with first moment metadata represented by moment node  402  and person metadata represented by person node  430 . Network  107   n  may also include a person social group metadata asset node  432  that may be defined to represent person social group metadata indicative of a first social group and that may be correlated (e.g., by social group) with moment node  402 , and each one of person identity metadata asset node  426  and person identity metadata asset node  428  and person identity metadata asset node  430  may be correlated (e.g., by belonging) with person social group metadata asset node  432  (e.g., when the first identity (e.g., John Doe) and the second identity (e.g., Jane Doe) and the third identity (e.g., the first unknown person) are determined to be of a particular social group). Network  107   n  may also include a location home metadata asset node  434  that may be defined to represent location home metadata indicative of a first home or residence, and location address metadata asset node  408  may be correlated (e.g., by home) with location home metadata asset node  434  (e.g., when the first address (e.g., 22 Skyline Drive, Wellesley, Mass.,  02482 , U.S.A.) is determined to be a home or residence), while each one of person identity metadata asset node  426  and person identity metadata asset node  428  may be correlated (e.g., by residence) with location home metadata asset node  434  (e.g., when each one of the first identity (e.g., John Doe) and the second identity (e.g., Jane Doe) is determined to reside at the first home). Additionally or alternatively, as shown, first moment metadata asset node  402  may be correlated (e.g., by presence) with at least one scene metadata asset node, such as a scene metadata asset node  436  that may be defined to represent scene metadata indicative of a first scene (e.g., a dog). At least one MCI  310  of library  105  may be associated with first moment metadata represented by moment node  402  and scene metadata represented by scene node  436 . 
     Second moment metadata asset node  404  may be correlated (e.g., by date) with at least one time date metadata asset node  438  that may be defined to represent time date metadata indicative of a second date (e.g., Jun. 30, 2016) and/or may be correlated (e.g., by date) with at least one other time date metadata asset node  440  that may be defined to represent time date metadata indicative of a third date (e.g., Jul. 1, 2016) and/or may be correlated (e.g., by address) with at least one location address metadata asset node  442  that may be defined to represent at least one location address metadata indicative of a second address (e.g., 350 5 th  Avenue, New York, N.Y. 10118, U.S.A. or an associated geographic coordinate system (e.g., latitude, longitude, and/or altitude)). At least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and location metadata represented by location node  408  and at least one of time metadata represented by time node  438  and time metadata represented by time node  440 . As shown, time date metadata asset node  438  (e.g., indicative of Jun. 30, 2016) may be correlated (e.g., by season) with a time season metadata asset node  444  that may be defined to represent time season metadata indicative of a second season (e.g., Summer) and/or may be correlated (e.g., by year) with a time year metadata asset node  446  that may be defined to represent time year metadata indicative of a second year (e.g., 2016) and/or may be correlated (e.g., by month) with a time month metadata asset node  448  that may be defined to represent time month metadata indicative of a second month (e.g., June) and/or may be correlated (e.g., by day) with a time day metadata asset node  450  that may be defined to represent time day metadata indicative of a second day (e.g.,  30 ), and, although not shown, it is to be understood that time date metadata asset node  438  may be correlated with any other suitable types of metadata asset nodes within network  107   n , including, but not limited to, a time day of week metadata asset node that may be defined to represent time day of week metadata indicative of a day of week (e.g., Thursday) and/or the like. Additionally or alternatively, as shown, time date metadata asset node  440  (e.g., indicative of Jul. 1, 2016) may be correlated (e.g., by season) with time season metadata asset node  444  that may be defined to represent time season metadata indicative of the second season (e.g., Summer) and/or may be correlated (e.g., by year) with a time year metadata asset node  446  that may be defined to represent time year metadata indicative of the second year (e.g.,  2016 ) and/or may be correlated (e.g., by month) with a time month metadata asset node (not shown) that may be defined to represent time month metadata indicative of a third month (e.g., July) and/or may be correlated (e.g., by day) with a time day metadata asset node (not shown) that may be defined to represent time day metadata indicative of a third day (e.g.,  1 ), and, although not shown, it is to be understood that time date metadata asset node  440  may be correlated with any other suitable types of metadata asset nodes within network  107   n , including, but not limited to, a time day of week metadata asset node that may be defined to represent time day of week metadata indicative of a day of week (e.g., Friday) and/or the like. Additionally or alternatively, as shown, location address metadata asset node  442  (e.g., indicative of 350 5 th  Avenue, New York, N.Y. 10118, U.S.A.) may be correlated (e.g., by city) with a location city metadata asset node  452  that may be defined to represent location city metadata indicative of a second city (e.g., New York City), which may be correlated (e.g., by state) with a location state metadata asset node  454  that may be defined to represent location state metadata indicative of a second state (e.g., New York), which may be correlated (e.g., by country) with location country metadata asset node  424  that may be defined to represent location country metadata indicative of the first country (e.g., United States of America), and, although not shown, it is to be understood that location address metadata asset node  442  may be correlated (e.g., directly or via another node) with any other suitable types of metadata asset nodes within network  107   n , including, but not limited to, a location ZIP code metadata asset node that may be defined to represent location ZIP code metadata indicative of a ZIP code and/or the like. 
     Additionally or alternatively, as shown, second moment metadata asset node  404  may be correlated (e.g., by presence) with at least one person identity metadata asset node, such as person identity metadata asset node  426  that may be defined to represent person identity metadata indicative of the first identity (e.g., John Doe) and/or person identity metadata asset node  428  that may be defined to represent person identity metadata indicative of the second identity (e.g., Jane Doe) and/or a person identity metadata asset node  456  that may be defined to represent person identity metadata indicative of a fourth identity (e.g., Jenn Doe) and/or a person identity metadata asset node  466  that may be defined to represent person identity metadata indicative of a fifth identity (e.g., a second unknown person). Although not shown, person identity metadata asset node  456  may be correlated (e.g., by offspring) with person identity metadata asset node  426  and with person identity metadata asset node  428  (e.g., when the fourth identity (e.g., Jenn Doe) is determined to be the offspring of the first identity (e.g., John Doe) and of the second identity (e.g., Jane Doe)). At least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and person metadata represented by person node  426 , at least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and person metadata represented by person node  428 , at least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and person metadata represented by person node  456 , and at least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and person metadata represented by person node  466 . Network  107   n  may also include a person social group metadata asset node  458  that may be defined to represent person social group metadata indicative of a second social group and that may be correlated (e.g., by social group) with moment node  404 , and each one of person identity metadata asset node  426  and person identity metadata asset node  428  and person identity metadata asset node  456  may be correlated (e.g., by belonging) with person social group metadata asset node  458  (e.g., when the first identity (e.g., John Doe) and the second identity (e.g., Jane Doe) and the fourth identity (e.g., Jenn Doe) are determined to be of a particular social group (e.g., a family)), while it is to be noted that person identity metadata asset node  466  may not be correlated with person social group metadata asset node  458  (e.g., when the fifth identity (e.g., second unknown person) is determined not to be of a particular social group (e.g., a family)). However, network  107   n  may also include a person social group metadata asset node  468  that may be defined to represent person social group metadata indicative of a third social group and that may be correlated (e.g., by social group (not shown)) with moment node  402 , and each one of person identity metadata asset node  456  and person identity metadata asset node  466  may be correlated (e.g., by belonging) with person social group metadata asset node  468  (e.g., when the fourth identity (e.g., Jenn Doe) and the fifth identity (e.g., second unknown person) are determined to be of a particular social group). Network  107   n  may also include a location area metadata asset node  460  that may be defined to represent location area metadata indicative of a first area (e.g., an area of interest), such as the Empire State Building, and location address metadata asset node  442  may be correlated (e.g., by area) with location area metadata asset node  460  (e.g., when the second address (e.g., 350 5 th  Avenue, New York, N.Y. 10118, U.S.A.) is determined to be a particular area (e.g., an area of interest)). Additionally or alternatively, as shown, second moment metadata asset node  404  may be correlated (e.g., by point of interest (“POI”)) with at least one place POI metadata asset node, such as a place POI metadata asset node  462  that may be defined to represent place POI metadata indicative of a first POI (e.g., culture). At least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and place POI metadata represented by place POI node  462 . Additionally or alternatively, as shown, second moment metadata asset node  404  may be correlated (e.g., by region of interest (“ROI”)) with at least one place ROI metadata asset node, such as a place ROI metadata asset node  464  that may be defined to represent place ROI metadata indicative of a first ROI (e.g., urban). At least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and place ROI metadata represented by place ROI node  464 . Additionally or alternatively, as shown, second moment metadata asset node  404  may be correlated (e.g., by presence) with at least one scene metadata asset node, such as scene metadata asset node  436  that may be defined to represent scene metadata indicative of the first scene (e.g., a dog). At least one MCI  310  of library  105  may be associated with second moment metadata represented by moment node  404  and scene metadata represented by scene node  436 . 
     It is to be understood that  FIG.  4    is just exemplary of what may only be a portion of one illustrative metadata network  107   n  of system  1 . For example, any node of  FIG.  4    may be correlated with one or more other nodes of network  107   n  not shown in  FIG.  4   . For example, person identity metadata node  426  may be correlated (not shown) with one or more additional moment metadata nodes of network  107   n  in addition to moment nodes  402  and  404  (e.g., a third moment node  470  that may be representative of third moment metadata indicative of a third moment after the second moment represented by moment node  404 ). Additionally or alternatively, location country metadata node  424  may be correlated with one or more additional location nodes of network  107   n  in addition to location nodes  422  and  454 . Additionally or alternatively, moment node  404  may be correlated with one or more additional location nodes of network  107   n  in addition to location node  442  (e.g., one or more MCIs  310  of library  105  may be associated with second moment metadata represented by moment node  404  and location address metadata other than the location address represented by location address node  442  (e.g., another MCI  310  associated with moment node  404  may be associated with third location address metadata indicative of a third location address other than 350 5 th  Avenue, New York, N.Y. 10118, (e.g., an address associated with another area of interest other than the Empire State Building))). Network  107   n  may be further populated with one or more additional nodes and/or one or more additional edges between nodes when one or more new metadata assets may be determined and associated with one or more MCIs already associated with moment metadata represented by one of moment node  402  and moment  404  and/or when one or more new MCIs may be associated with moment metadata represented by one of moment node  402  and moment node  404  and/or when further processing is carried out by system  1  on any existing metadata and/or contextual data available to system  1 . It is to be appreciated that certain metadata assets and their respective nodes may be associated with individual MCIs and/or with other nodes (e.g., moment nodes) that may be associated with individual MCIs or groups of MCIs. For example, a moment node may be associated with each MCI in a group of MCIs, where each MCI in the group of MCIs may be associated with time metadata indicative of a time within the time range of the moment and/or may be associated with location metadata indicative of a location within the location range of the moment. As another example, a scene node (e.g., scene metadata asset node  436  that may be defined to represent scene metadata indicative of a first scene (e.g., a dog)) may be correlated with moment node  402 , which may be associated with each MCI that has time and/or location metadata related to the time and location constraints of the moment, while only one or some but not all of those MCIs may be associated with scene metadata indicative of the scene represented by the scene node. Therefore, a scene node may be correlated to a moment node that is associated with a group of MCIs, while the scene node may also be directly associated with only one or some (or maybe all) of the MCIs of that group. 
     System  1  may be configured to generate additional nodes based on moment nodes in any suitable manner, including, but not limited to, determining (e.g., detecting, receiving, inferring, deriving, or otherwise obtaining a new metadata asset associated with a moment node by cross-referencing the new metadata asset with other assets in network  107   n  and/or generating a node for each metadata asset of library  105 . System  1  may be configured to refine one, some, or each metadata asset associated with a moment nodes in any suitable manner, such as based on a probability distribution (e.g., a discrete probability distribution, a continuous probability distribution, etc.). For example, a Gaussian distribution may be used to determine a distribution of at least some metadata assets, such as the primary primitive metadata assets. For this example, the distribution may be used to ascertain a mean, a median, a mode, a standard deviation, a variance, and/or any other suitable characteristic associated with the distribution of the primary primitive metadata assets. System  1  may be configured to use the Gaussian distribution to select or filter out a subset of the primary primitive metadata assets that may be within any suitable predetermined criterion (e.g., 1 standard deviation (e.g., 68%), 2 standard deviations (e.g., 95%), 3 standard deviations (e.g., 99.7%), etc.). Hence, such selection/filtering operation(s) may be operative to assist with identifying relevant primary primitive metadata assets for MCP management and/or with filtering out noise and/or unreliable primary primitive metadata assets. Consequently, other types of metadata (e.g., inferred metadata assets, etc.) that may be associated with, determined from, or inferred from the primary primitive metadata assets may also be relevant and relatively noise-free. As another example, a Gaussian distribution may be used to determine a distribution of one, some, or each moment nodes. For this example, the distribution may be used to ascertain a mean, a median, a mode, a standard deviation, a variance, and/or any other suitable characteristic associated with the distribution of the moments. System  1  may be operative to use the Gaussian distribution to select or filter out a subset of the moment nodes that may be within any suitable predetermined criterion (e.g., 1 standard deviation (e.g., 68%), 2 standard deviations (e.g., 95%), 3 standard deviations (e.g., 99.7%), etc.). Hence, such selection/filtering operation(s) may be operative to assist with identifying relevant moment nodes for MCP management and/or with filtering out noise and/or unreliable primary inferred metadata assets or otherwise. Consequently, other types of metadata (e.g., primary primitive metadata assets, auxiliary inferred metadata assets, etc.) that may be associated with, determined from, or extracted from the moment metadata assets may also be relevant and relatively noise-free. Noise may occur due to primary primitive metadata assets that may be associated with one or more irrelevant MCIs, where such MCIs may be determined based on the number of MCIs associated with a primary primitive metadata asset. For example, a primary primitive metadata asset associated with two or less MCIs may be designated as noise. This may be because such metadata assets (and their associated MCIs) may be irrelevant given the little information they provide. For example, the more important or significant an event is to a user, the higher the likelihood that the event is captured using a large number of MCIs (e.g., three or more, etc.). For this example, the probability distribution described above may enable selecting the primary primitive metadata asset associated with these MCIs. This may be because the number of MCIs associated with the event may suggest an importance or relevance of the primary primitive metadata asset. In contrast, insignificant events may have only one or two MCIs captured, and the corresponding primary primitive metadata asset may not add much to MCP management based on the use of a metadata network, for example. The immediately preceding examples may also be applicable to any types of metadata. 
     System  1  may be configured to determine a correlation weight (e.g., confidence weight and/or a relevance weight) for one, some, or each metadata asset and/or one, some, or each correlation between any two metadata nodes representative of any two metadata assets. As used herein, a “confidence weight” and its variations may refer to a value (e.g., an integer, etc.) that may be used to describe a certainty that a metadata asset correctly identifies a feature or characteristic of one or more MCIs (e.g., one or more MCIs associated with a moment). For example, a confidence weight of 0.6 (e.g., out of a maximum of 1.0) can be used to indicate a 60% confidence level that a feature (e.g., a scene) in one or more MCIs associated with a moment is a dog. As used herein, a “relevance weight” and its variations may refer to a value (e.g., an integer, etc.) that may be used to describe an importance assigned to a feature or characteristic of one or more MCIs (e.g., one or more MCIs associated with a moment) as identified by a metadata asset. For example, a first relevance weight of 0.85 (e.g., out of a maximum of 1.0) can be used to indicate that a first identified feature in an MCI (e.g., a person) is very important while a second relevance weight of 0.50 (e.g., out of a maximum of 1.0) can be used to indicate that a second identified feature in an MCI (e.g., a dog) is not as important. 
     As shown in  FIG.  4   , for example, system  1  may be operative to estimate that one or more metadata assets associated with one or more MCIs associated with moment node  402  describe a dog. For this example, a correlation weight of a correlation  435  between node  402  and node  436  may be assigned a value 0.8, which may be any suitable confidence weight, any suitable relevance weight, or any suitable combination of any suitable confidence weight and any suitable relevance weight (e.g., a confidence weight (“C-weight”) may be determined to be a value of 0.9 to indicate a 90% confidence level that a scene dog metadata asset of scene dog metadata asset node  436  is or ought to be associated with moment node  402  (e.g., with one or more MCIs associated with the first moment represented by moment node  402 ) and a relevance weight (“R-weight”) may be determined to be a value of 0.7 to indicate that a scene dog metadata asset of scene dog metadata asset node  436  is a relatively important feature of moment node  402  (e.g., of one or more MCIs associated with the first moment represented by moment node  402 ), such that a correlation weight (“weight”) may be an average value of 0.8 (alternatively, a correlation weight may be based on a difference between a confidence weight and a relevance weight for a particular edge)). With specific regard to scene metadata assets and/or person identity metadata assets associated with any suitable image MCIs, correlation weights and/or confidence weights and/or relevance weights may be detected via any suitable feature detection techniques that may include analyzing such metadata associated with one or more MCIs. For example, system  1  may be configured to determine any suitable weight(s) using metadata associated with one or more MCIs by applying known feature detection techniques. Relevance can be statically defined in a metadata network from external constraints. For example, relevance can be based on information (e.g., contextual information) that may be acquired from any suitable sources, such as social network data, calendar data, and/or the like. Additionally or alternatively, relevance may be based on any suitable internal constraints, where, for example, as more detections of a metadata asset are made, its relevance can be increased. Relevance may also retard as fewer detections are made. For example, as more detections of the second identified person metadata associated with person metadata node  428  (e.g., Jane Doe) are made over a predetermined period of time (e.g., an hour, a day, a week, a year, etc.), that person&#39;s relevance may be increased to indicate that person&#39;s importance (e.g., to a user of system  1  (e.g., to John Doe)). Confidence can be dynamically generated based on the ingest of any suitable metadata in a metadata network. For instance, a detected person in an MCI may be linked with information (e.g., contextual information) about that person as may be obtained from a contacts application, a calendar application, a social networking application, and/or any other suitable source to determine a level of confidence that the detected person is correctly identified. For a further example, an overall description of a scene in an MCI may be linked with geo-position information that may be acquired from metadata associated with the MCI to determine the level of confidence. Many other examples are possible. In addition, confidence can be based on any suitable internal constraints, where, for example, as more detections of a metadata asset are made, its identification confidence may be increased. Confidence can also retard as fewer detections are made. 
       FIG.  6    is a flowchart of an illustrative process  600  for operating system  1  (e.g., a process that may be performed by media management system  500  of  FIG.  5   ) for defining a collection of media content items of a media library for a relevant interest (e.g., for identifying a subset of MCIs of a media library, where each MCI of the subset is associated with an interest (e.g., hobby or avocation or concernment) that has been determined to be of some relevance). Process  600  may use any suitable metadata (e.g., any suitable metadata network and/or any suitable contextual data) that may be associated with the media library in any suitable manner in order to define a collection of media content items for any suitable interest. Process  600  may include (i) identifying a person identity associated with the media library (e.g., using any suitable identity metadata for a particular identity (e.g., a verified or unverified identity) or the like), (ii) identifying a location intimately associated with the person identity (e.g., a home or office or any other suitable type of location frequently associated with the person identity (e.g., using any suitable location metadata and/or correlation information for a particular location with respect to the person identity or the like)), (iii) identifying an interest that is associated in a particular manner with the identified location (e.g., an interest that is associated with at least 3 moments that are associated with the identified location (e.g., using any suitable interest metadata (e.g., scene data) and/or correlation information for a particular interest (e.g., an activity, an animal, an instrument, a baby, etc.) with respect to the identified location or the like)), and (iv) identifying each MCI of the media library that is associated with the person identity and with the interest (e.g., identifying each moment that may be associated with both the person identity and the interest, and then identifying from the MCIs associated with such moments, each MCI associated with the hobby). Then a collection may be defined to include those identified MCIs, and the collection may be used in any suitable manner, such as to provide an album or a composite presentation based on at least some of the MCIs of the defined collection. A majority or the entirety of process  600  may be carried out without any user interaction (e.g., transparent to a user of system  1 ), which, for example, may reduce the cognitive burden on a user and/or avoid any tedious classification of media by a user, thereby creating a more efficient human-machine interface. 
     At operation  602  of process  600 , one or more processors of the system may select a person identity associated with a media library. For example, any suitable person identity associated with media library  105  may be selected, such as the first verified identity John Doe that may be indicated by person identity metadata that may be represented by person identity metadata asset node  426  of metadata network  107   n  or the first unverified unknown identity that may be indicated by person identity metadata that may be represented by person identity metadata asset node  430  of metadata network  107   n , where the person identity may be selected in any suitable manner, such as automatically by system  1  based on any suitable information (e.g., based on the prominence of the identity with respect to media library  105  (e.g., by analyzing the metadata associated with media library  105 )) or through user-selection (e.g., a user may select (e.g., via any suitable system user interface (“UI”) (e.g., I/O component  109   a )) any suitable person identity associated with media library  105 ). 
     At operation  604  of process  600 , one or more processors of the system may determine if there is at least one location intimately associated with the selected person identity and, if so, process  600  may advance to operation  606  of process  600 , otherwise, process  600  may return to operation  602  where a different person identity may be selected. A determination of operation  604  as to whether one or more locations may be intimately associated with the person identity selected at operation  602  may be made in any suitable manner, such as through processing any suitable metadata associated with media library  105  (e.g., any explicit and/or inferred metadata and/or contextual data). For example, as shown in  FIG.  4   , analysis of metadata network  107   n  may be operative to determine at operation  604  that, when the first person identity represented by person identity metadata asset node  426  of metadata network  107   n  is selected at operation  602 , person identity metadata asset node  426  may be intimately associated with location home metadata asset node  434  that may be defined to represent location home metadata indicative of a first home or residence, and location address metadata asset node  408  may be correlated (e.g., by home) with location home metadata asset node  434 . An intimate association between a location and a person identity may be indicative of the person identity living at the location (e.g., place of residence (e.g., primary residence or secondary residence (e.g., summer home)) and/or may be indicative of the person identity working at the location (e.g., place of business) and/or may be indicative of the person identity having any other suitable strong relationship to the location (e.g., the location may be the home of the person identity&#39;s parent or child). Two or more intimate locations may be identified at operation  604  with respect to a selected person identity (e.g., a primary residence and a summer residence). Alternatively, in some embodiments, only determination of a primary residence of the selected person identity may be operative to satisfy operation  604 . 
     At operation  606  of process  600 , one or more processors of the system may determine if there is at least a threshold number of moments associated with both an interest and any location intimately associated with the selected person identity and, if so, process  600  may advance to operation  608  of process  600 , otherwise, process  600  may return to operation  602  where a different person identity may be selected. A determination of operation  606  as to whether at least a threshold number of moments may be associated with not only a particular interest but also any location identified at operation  604  may be made in any suitable manner, such as through processing any suitable metadata associated with media library  105 . For example, as shown in  FIG.  4   , analysis of metadata network  107   n  may be operative to determine at operation  606  that, when the first person identity represented by person identity metadata asset node  426  of metadata network  107   n  is selected at operation  602  and at least the location address represented by location address metadata asset node  408  is determined at operation  604  to be intimately associated with that selected person identity (e.g., via location home metadata asset node  434 ), at least the first moment represented by first moment metadata asset node  402  may be not only correlated (e.g., by location) with location address metadata asset node  408  but also correlated (e.g., by presence) with scene metadata asset node  436  that may be representative of a first interest (e.g., first scene (e.g., a dog)). If the threshold number of moments of operation  606  is defined to be the number 1, then this correlation of moment node  402  with both location address node  408  and interest scene dog node  436  may be enough to satisfy operation  606 . However, if the threshold number of moments of operation  606  is defined to be the number 2, then at least one other moment (i.e., a moment different than the first moment of moment node  402 ) would have to be identified at operation  606  as being associated with not only interest scene dog node  436  but also with any location identified at operation  604  (e.g., the same location of address node  408  associated with interest scene dog node  436  and the first moment, or any other location identified at operation  604  (e.g., if operation  604  identified two or more locations intimately associated with the selected person identity (e.g., a primary residence and a summer home))) in order to satisfy operation  606 . That is, in order to satisfy the condition of operation  606 , at least a threshold number of moments of media library  105  must be identified, where each of those moment must be associated with the same particular interest, and where each of those moment must be associated with any location identified at operation  604  (e.g., a first of the identified moments may be associated with interest I and location X, while a second of the identified moments may be associated with interest I and location Y, and while a third of the identified moments may be associated with interest I and location Z, as long as each one of locations X, Y, and Z were identified at operation  604  as being intimately associated with the person identity selected at operation  602 ). 
     The threshold number of moments of operation  606  may be defined as any suitable number in any suitable manner. For example, the threshold number of moments of operation  606  may be the number 1, the number 2, the number 3, the number 4, or the number 5. Alternatively, the threshold number of moments of operation  606  may be a percentage of the total number of moments of the media library that may be associated with the particular interest (e.g., the first scene (e.g., a dog) of scene node  436 ), a percentage of the total number of moments of the media library that may be associated with any location identified at operation  604 , a percentage of the total number of moments of the media library, and/or the like, where the percentage may be any suitable number, such as 5%, 10%, 20%, 30%, 40%, 50%, or the like. Alternatively or additionally, the threshold number may be determined using any suitable calculation based on the distribution of the MCIs (e.g., using standard deviation). Therefore, operation  606  may be satisfied if a particular interest is determined to be associated with at least a particular number of moments also associated with a location that is intimately associated with a particular person identity, such that operation  606  may only be satisfied for an interest that is associated with three different time ranges at a particular person identity&#39;s intimate location(s), thereby providing process  600  with enough confidence to handle the interest as a relevant interest for that person identity. 
     The particular interest of operation  606  may be any suitable type of interest, including one or more particular types of entities that may be represented by any suitable scene metadata assets and, thus any suitable scene metadata asset nodes (e.g., node  436  of network  107   n ), or by any other suitable type of metadata of media library  105 , where the type of interest may include, but is not limited to, any suitable hobby, pet (e.g., dog (generally or a specific breed (e.g., German Shepherd, Retriever, Spaniel, etc.)), cat, bird, etc.), instrument (e.g., generally or piano, guitar, violin, etc.), activity (e.g., generally or cooking, painting, video games, jacuzzi, basketball, boxing, juggling, magic, dancing, billiards, etc.), baby (e.g., a person object that may typically not be associated with a particular identity (e.g., verified or unverified)), and/or the like, where, as mentioned, scene metadata may be indicative of an overall description of an activity or situation associated with one or more MCIs based on any objects that may be detected therein (e.g., if a MCI includes a group of images, then scene metadata for the group of images may be determined using detected objects in one or more of the images (e.g., the detection of a large cake with candles and/or balloons in at least two images in the group can be used to associate “birthday” scene metadata with each of the images)), where such objects or scene indicators or content indicators may be any suitable objects (e.g., a detected animal, a detected company logo, a detected piece of furniture, a detected instrument, etc.) that may be able to be detected in a media content item using any suitable techniques (e.g., any suitable image processing techniques), which may be metadata  350  of media library  105  and/or any suitable node(s) of network  107   n . The particular interest of operation  606  may be of any suitable granularity, such as an “animal” or an “animal mammal” or an “animal mammal canine” or an “animal mammal canine dog” or an “animal mammal canine dog shepherd” or an “animal mammal canine dog shepherd german” or the like, but the same level of granularity may be used for each one of the threshold number moments to satisfy operation  606 . Operation  606  may be configured to satisfy the condition of operation  606  by first analyzing a first particular interest with respect to the location(s) of operation  604 , where the first particular interest may be the most prevalent interest of media library  105 , and if that analysis does not satisfy operation  606 , then the next most prevalent interest may be analyzed, and so on until an interest is identified that satisfies operation  606  for the location(s) of operation  604  such that process  600  may advance to operation  608 , otherwise process  600  may return to operation  602  and select a different person identity. In some embodiments, a particular interest to be used at operation  606  may be selected in any suitable manner (e.g., via any suitable UI) by a user or in response to any suitable action (e.g., a user tagging a “dog” in one or more MCIs (e.g., any suitable explicit user metadata  330 )) or in any other suitable manner. 
     At operation  608  of process  600 , one or more processors of the system may identify each moment of library  105  that may be associated with not only a particular person identity (e.g., the person identity selected at operation  602 ) but also a particular interest (e.g., the particular interest satisfying operation  606  (e.g., with respect to any location(s) intimately associated with the person identity)). Therefore, in some embodiments, operation  608  may identify not only each one of the moments used to satisfy operation  606  (e.g., at least a threshold number of moments associated not only with the particular interest but also any location intimately associated with the selected person identity) but also any other moments that may be associated with the particular interest and with the selected person identity but that may not necessarily be associated with a location intimately associated with the selected person identity. The identification of moments of operation  608  may be made in any suitable manner, such as through processing any suitable metadata associated with media library  105 . For example, as shown in  FIG.  4   , analysis of metadata network  107   n  may be operative to identify at operation  608  that, when the first person identity represented by person identity metadata asset node  426  of metadata network  107   n  is selected at operation  602  and when the particular interest satisfying operation  606  is the first scene (e.g., a dog) represented by scene metadata asset node  436  of metadata network  107   n , at least each one of the first moment represented by first moment metadata asset node  402  and the second moment represented by second moment metadata asset node  404  may be associated (e.g., by presence) not only with person identity metadata asset node  426  of the selected person identity but also with scene metadata asset node  436  of the particular interest. 
     At operation  610  of process  600 , one or more processors of the system may determine whether any identified moment (e.g., any moment identified at operation  608 ) is a valuable interest moment, where an identified moment is a valuable interest moment when each MCI of at least a threshold percentage of the MCIs associated with the identified moment is associated with the particular interest, and, if so, process  600  may advance to operation  612  of process  600 , otherwise, process  600  may return to operation  606  where a different particular interest may be identified to attempt to satisfy the condition of operation  606  (or may return from operation  606  to operation  602  if such a different particular interest is not available). A determination of operation  610  as to whether a moment identified at operation  608  is a valuable interest moment may be made in any suitable manner, such as through processing any suitable metadata associated with media library  105 . For example, operation  610  may be operative to analyze metadata associated with particular MCIs of an identified moment to determine how many MCIs of the identified moment are directly associated (e.g., not only via the identified moment) with metadata indicative of the particular interest and then determine whether that number of MCIs is at least a threshold percentage of the total number of MCIs of the identified moment. As mentioned, each MCI of a moment may be directly associated with time metadata indicative of a time within a time range of the moment and directly associated with location metadata indicative of a location within a location range of the moment, such that the MCI may be associated with the moment. Moreover, when a non-moment node may be associated with a moment node, the non-moment node may be representative of metadata that may be directly associated with only one or some (and, in some situations, all) of the MCIs associated with the moment. For example, in some embodiments, while scene metadata asset node  436  representative of scene metadata indicative of the particular interest (e.g., the first scene (e.g., a dog)) may be correlated with moment node  402 , which may be associated with each MCI that has time and location metadata related to the time and location constraints of the moment, only one or some but not all of those MCIs may be associated with scene metadata indicative of the particular interest (e.g., the first scene (e.g., a dog)) represented by scene metadata asset node  436  (e.g., only 6 MCIs out of the 10 total MCIs that may be associated with moment node  402  may be associated with scene metadata indicative of the particular interest (e.g., only 60% of the MCIs associated with the first moment may also be associated with the particular interest (e.g., each MCI  310  of only 60% of the MCIs  310  associated with the first moment may be of an MCP  305  with metadata  311  indicative of the particular interest (e.g., each MCI  310  of only 60% of the MCIs  310  associated with the first moment may be detected to include pixel data indicative of a dog)))). None, one, some, or each of the moments identified at operation  608  may be determined to be a valuable interest moment at operation  610 . 
     The threshold percentage of operation  610  may be defined as any suitable number in any suitable manner. For example, the threshold percentage of MCIs of operation  610  may be 30%, 40%, 50%, 60%, 70%, 80%, or the like. Alternatively, the threshold percentage of operation  610  may vary based on the number of moments identified at operation  608  (e.g., the threshold percentage may be greater when more moments are identified, and may be smaller when less moments are identified, or vice versa). Alternatively, the threshold percentage may not be a percentage but may instead be a number, such as 5, or 10, or 20, or the like. In one particular embodiment, the threshold percentage of operation  610  may be 60%, while the threshold number of operation  606  may or may not be 3. Alternatively or additionally, rather than a threshold percentage, any suitable threshold number may be used at operation  610  as may be determined using any suitable calculation based on the distribution of the MCIs (e.g., using standard deviation). Therefore, operation  610  may be satisfied if at least one moment identified at operation  608  is associated with a number of MCIs of which at least a particular threshold percentage are associated with the particular interest (e.g., each MCI of at least 60% of the MCIs of an identified moment must be associated with the particular interest in order for that identified moment to be considered a valuable interest moment), thereby providing process  600  with enough confidence in the relevancy of that moment with respect to the particular interest. In some embodiments, operation  610  may also provide one or more additional conditions on whether an identified moment may be determined to be a valuable interest moment. For example, in addition to determining that an identified moment may be a valuable interest moment when each MCI of at least a threshold percentage of the MCIs associated with the identified moment is associated with the particular interest, operation  610  may also be configured to determine whether each MCI of at least another threshold percentage of the MCIs associated with the identified moment is associated with the selected person identity. As just one example, an identified moment may only be determined by operation  610  to be a valuable interest moment if not only at least X % of the moment&#39;s MCIs are associated with the particular interest but also at least Y % of the moment&#39;s MCIs are associated with the selected person identity (e.g., where Y % may be any suitable percentage greater than or less than X % (e.g., 60%)). As just one other example, an identified moment may only be determined by operation  610  to be a valuable interest moment if not only at least X % of the moment&#39;s MCIs are associated with the particular interest but also at least Y % of those MCIs of the X % are associated with the selected person identity (e.g., where Y % of X % of the MCIs of the identified moment must be associated with not only the particular interest but also the selected person identity). 
     At operation  612  of process  600 , one or more processors of the system may identify, from each valuable interest moment, each MCI that is associated with the particular interest (e.g., each MCI of at least the threshold percentage of the total number of MCIs of each valuable interest moment as associated with the particular interest). Therefore, operation  612  may be operative to identify all MCIs associated with the particular interest that may also be MCIs associated with a valuable interest moment that has been determined to be a relevant moment with respect to the particular interest. 
     At operation  614  of process  600 , one or more processors of the system may determine if there is at least a threshold number of identified MCIs (e.g., if the number of MCIs identified at operation  612  is at least a threshold number) and, if so, process  600  may advance to operation  616  of process  600 , otherwise, process  600  may return to operation  606  where a different particular interest may be identified to attempt to satisfy the condition of operation  606  (or may return from operation  606  to operation  602  if such a different particular interest is not available). The threshold number of identified MCIs of operation  614  may be defined as any suitable number in any suitable manner. For example, the threshold number of identified MCIs of operation  616  may be 5, 10, 20, 30, or the like. In some embodiments, the determination of operation  616  may be done for multiple ranges of time, such as is there at least a threshold number of identified MCIs for a first period of time (e.g., the year 2015 (e.g., is there at least a threshold number of the identified MCIs associated with metadata indicative of the year 2015)) and is there a threshold number of identified MCIs for a second period of time (e.g., the year 2016), and if not, then a determination may be made to determine if there is at least a threshold number of identified MCIs for a different period of time (e.g., the years 2015 and 2016 combined). Therefore, operation  616  may be satisfied if at least a particular number of identified MCIs are determined for at least one suitable period of time (e.g., a month, a year, two years, or the entire time span of library  105 , etc.), such that operation  616  may only be satisfied for a particular interest that is associated with at least a particular number of MCIs, where each MCI is also associated with a moment with at least a particular amount of relevancy with respect to the particular interest. 
     At operation  616  of process  600 , one or more processors of the system may define a collection of MCIs using at least a portion of the identified MCIs (e.g., a collection of MCIs that may include at least some of the MCIs identified at operation  612 ). In some embodiments, a single collection may be defined at operation  616  that may include some or most or all of the MCIs identified at operation  612 . Alternatively, if operation  614  may determine that a first set of at least the threshold number of identified MCIs are associated with a first time frame and that a second set of at least the threshold number of identified MCIs are associated with a second time frame, then operation  616  may define a first MCI collection that includes at least a portion or most or all of the first set of identified MCIs and may also define a second MCI collection that includes at least a portion or most or all of the second set of identified MCIs. Any MCI collection of MCIs defined at operation  616  may then be used in any suitable manner (e.g., for presentation to a user as an album of MCIs or as a composite presentation based on the MCIs of the collection), where the collection of MCIs may be indicative of MCIs associated with an interest of some relevancy. In some embodiments, the collection may be named or otherwise associated with textual information indicative of the selected person identity and the particular interest that resulted in the collection being defined, such as “John Doe&#39;s Dog” when the selected person identity was the first person identity of node  426  and the particular interest was the scene dog of node  436 . 
     It is understood that the operations shown in process  600  of  FIG.  6    are only illustrative and that existing operations may be modified or omitted, additional operations may be added, and the order of certain operations may be altered. In some embodiments, a particular interest may be associated with one or more elements that may be considered too similar to the particular interest in one or more ways such that each element may be considered a blacklist element for the particular interest, wherein a moment and/or MCI associated with both the particular interest and a blacklist element for the particular interest may be ignored with respect to one or more operations of process  600 . For example, continuing with the example of a particular interest being a “dog” (e.g., the scene dog of node  436 ), a blacklist element for a dog may be a “baby,” as a baby may be often falsely detected as a dog and/or a dog may be often falsely detected as a baby (e.g., due to one or more shortcomings in image processing and/or object recognition technology). In such an embodiment, operation  606  may be operative to determine whether or not there is at least a threshold number of moments that is not only (i) associated with the particular interest but also (ii) associated with any location intimately associated with the selected person identity and also (iii) not associated with any blacklist element of the particular interest. Additionally or alternatively, in such an embodiment, operation  608  may be operative to identify each moment that is not only (i) associated with the particular interest but also (ii) associated with the selected person identity and also (iii) not associated with any blacklist element of the particular interest. Additionally or alternatively, in such an embodiment, operation  610  may be operative to determine that an identified moment is a valuable interest moment when each MCI of at least a threshold percentage of the total number of MCIs associated with the identified moment is not only (i) associated with the particular interest but also (ii) not associated with any blacklist element of the particular interest. Additionally or alternatively, in such an embodiment, operation  612  may be operative to identify, from each valuable interest moment, each MCI that is not only (i) associated with the particular interest but also (ii) not associated with any blacklist element of the particular interest. Such handling of one, some, each, or any blacklist elements of a particular interest may be operative to increase confidence in the MCIs that may be identified for defining a collection of MCIs for the particular interest. 
     Operation  604  may be omitted in some embodiments of process  600 , whereby process  600  may advance from operation  602  to operation  606  when operation  602  is satisfied. In such embodiments, operation  606  may be operative to determine whether or not there is at least a threshold number of moments that is not only (i) associated with the particular interest but also (ii) associated with the selected person identity (e.g., generally associated with the selected person identity without any condition with respect to any location (e.g., a location that may be intimately associated with the selected person identity)) and, in some embodiments, also (iii) not associated with any blacklist element of the particular interest. 
     Operations  604  and  606  may be omitted in some embodiments of process  600 , whereby process  600  may advance from operation  602  to operation  608  when operation  602  is satisfied. In such embodiments, operation  608  may be operative to identify each moment that is not only (i) associated with the particular interest but also (ii) associated with the selected person identity (e.g., generally associated with the selected person identity without any condition with respect to any location (e.g., a location that may be intimately associated with the selected person identity) or with respect to any threshold number of such moments) and, in some embodiments, also (iii) not associated with any blacklist element of the particular interest. 
     Operation  608  may be omitted in some embodiments of process  600 , whereby process  600  may advance from operation  606  to operation  610  when operation  606  is satisfied. Additionally, in some embodiments, operations  606  and  608  may be omitted in some embodiments of process  600 , whereby process  600  may advance from operation  604  to operation  610  when operation  604  is satisfied. In either of such embodiments, operation  610  may be operative to determine whether a moment that may be associated with the particular interest and any location intimately associated with the selected person identity is a valuable interest moment when each MCI of at least a threshold percentage of the total number of MCIs associated with the moment is (i) associated with the particular interest and, in some embodiments, also (iii) not associated with any blacklist element of the particular interest. In such embodiments, operation  610  may be operative to use each moment that may be associated with the particular interest and any location intimately associated with the selected person identity as an identified moment for the purposes of defining a valuable interest moment at operation  610 , such that any valuable interest moment identified at operation  610  would be associated with the particular interest and any location intimately associated with the selected person identity (e.g., as opposed to a moment that might not be associated with such a location intimately associated with the selected person identity). Alternatively, in some embodiments, operation  608  may be included in process  600  but operation  610  may be operative to also define each moment that may be associated with the particular interest and any location intimately associated with the selected person identity as a valuable interest moment, such that operation  612  may be operative to identify each MCI associated with the particular interest from each moment that is associated with the particular interest and with any location intimately associated with the selected person identity. 
     In some embodiments, any suitable operation(s) of process  600  may be operative to define any suitable “person identity interest” metadata that may be associated with one or more MCIs and/or one or more moments and/or one or more nodes of network  107   n . For example, each MCI identified at operation  612  or each MCI used to define a collection at operation  616  may be associated with “person identity interest” metadata that may be indicative of the particular interest determined to be relevant to the selected person identity may be associated with that MCI. A “person identity interest” node associated with such “person identity interest” metadata may be added to metadata network  107   n  and may be correlated to the person identity node for the selected person identity (e.g., to person identity node  426 ) and/or may be correlated to the particular interest node for the particular interest (e.g., to scene dog node  436 ) and/or may be correlated to each moment node associated with each one of the person identity and particular interest (e.g., moment nodes  402  and  404 ) and/or associated with each MCI identified at operation  612  and/or operation  616 , and/or the like. Such “person identity interest” metadata and/or node may be used to enable faster MCI collection definition of a large media library and/or may be operative to enable presentation of such identified person identity interests (e.g., in any suitable UI to a user, which may enable the user to request a collection of MCIs associated with a selected person identity interest). 
     System  1  may be operative to manage a media library in order to define a collection of media content items of a media library for a relevant interest, where such a collection of MCIs may be presented to a user in any suitable manner. For example, as shown in  FIG.  5   , system  1  may include a media management system  500  that may be provided to manage media of media library  105  of system  1 , such as, for example, to (i) generate metadata network  107   n , (ii) relate and/or present at least two MCIs  310  based on metadata network  107   n , (iii) determine and/or present interesting MCIs  310  of library  105  based on metadata network  107   n  and predetermined criterion, (iv) select and/or present representative MCIs  310  to summarize a collection (e.g., a moment) of media content items based on input specifying the representative group&#39;s size, and/or (v) use metadata network  107   n  and/or any other data associated with library  105  to define a collection of media content items of a media library for a relevant interest. Media management system  500  may include any suitable modules, including, but not limited to, MCP management system  107 , which may include metadata network  107   n , a collection generator  505 , a layout generator  510 , a context identifier  515 , a scoring engine  520 , a media compositor or collection enhancer  575 , which may include a video compositor  525  and/or an audio compositor  530 , and a rendering engine  535 . As shown, media management system  500  may have access to media library  105  of MCPs  305 , metadata network  107   n  of MCP management system  107 , media grouping templates  545 , media collections  550 , an audio library  555 , a video presentation storage  560 , and/or an audio presentation storage  565 . 
     Media management system  500  may be operative to provide a media-compositing application (e.g., an application  103 ) that may automatically organize MCIs  310  of library  105  into different MCI collections and/or may enable a user to define MCI collections in any suitable manner, and that may then produce any suitable user interface (“UI”) layout that may identify the defined MCI collections as collections that may be viewed by a user (e.g., as individual MCIs of a selected collection) or for which the application may display composite presentations (e.g., video (e.g., audio/visual) presentations for a selected collection). Media management system  500  may enable such a media-compositing application that may be executed by system  1 . Collection generator  505  and layout generator  510  may be operative to perform an automated process that may (i) analyze the MCIs (e.g., analyzes the MCIs and any associated metadata of library  105 , including metadata network  107   n  and/or any suitable contextual data) to define one or more MCI collections and (ii) produce a UI layout that may identify the defined MCI collections as collections for which the application can display composite presentations. In performing such operations, these modules may use scoring engine  520  and/or context identifier  515 . For example, to define the MCI collections, collection generator  505  may use one or more media grouping templates (“templates”) of template storage  545  to try to associate each MCI of library  105  with one or more template instances. In some embodiments, a template in template storage  545  may be defined by reference to a set of media matching attributes and collection generator  505  may compare a template&#39;s attribute set with the content and/or metadata of the MCIs in order to identify MCIs that may match the template attributes, such that, when a sufficient number of MCIs match the attribute set of a template, the application may define a template instance by reference to the matching MCIs and may store such a template instance in media collection storage  550 . In some embodiments, a template instance may include a list of MCI identifiers that identify the MCI&#39;s that matched the instance&#39;s template attribute set. Collection generator  505  may be operative to define multiple template instances for a template, such as where the templates may include (i) location-bounded templates (e.g., MCIs captured within a region with a particular radius), (ii) time-bounded templates (e.g., MCIs captured within a particular time range and/or date range), (iii) time-bounded and location-bounded templates (e.g., mornings at a beach), (iv) content-defined templates (e.g., MCIs containing a relevant interest (e.g., a dog as described above) or MCIs containing smiles, etc.), and (v) user-metadata based templates (e.g., MCIs from albums created by a user, MCIs shared by a user with others, MCIs having particular user-defined metadata tags, etc.). 
     Based on template definition, layout generator  510  may generate any suitable UI layouts that may identify one or more defined template instances as MCI collections for which the application can display composite presentations. Layout generator  510  may generate a UI layout that identifies a subset of defined template instances that may be contextually relevant to a user of the device at a particular time (e.g., as based on any suitable contextual attributes that may be provided by context identifier  515  and any template instance scores that may be computed by scoring engine  520  (e.g., to assess whether one template instance is contextually more relevant than, and/or better than, another template instance at a particular time, scoring engine  520  may generate a score for each template instance, rank the template instances based on the generated scores, and then generate a UI layout based on the rankings so that a user may choose a template instance (e.g., MCI collection) for use in presenting a related composite presentation), where a template instance&#39;s score may be based on any suitable contextual information, such as (i) contextual attributes that may relate to the time at which the UI layout is being generated and/or displayed, and (ii) quality and/or quantity attributes that may relate to quality and/or quantity of the MCIs of the template instance, where examples of contextual attributes may include (i) time, (ii) location of device  100 , (iii) location of future calendared events stored on, or accessible by, device  100 , (iv) locations derived from electronic tickets stored on device  100 , and/or the like). 
     When a user selects a particular template instance via any suitable UI, or when system  1  may automatically select a particular template instance in any suitable manner, layout generator  510  may direct collection enhancer  575  to generate media collection enhancement definitions that may be rendered by engine  535  to produce an enhancement (e.g., a composite presentation) for consumption by the user (e.g., via any suitable UI (e.g., I/O component  109   a )) For example, layout generator  510  may be operative to direct video compositor  525  and/or audio compositor  530  to generate, for the selected template instance, the definitions of video and audio presentation components (e.g., for storage in storage  560  and/or  565 ), which rendering engine  535  may then render to produce a composite presentation for display. Collection enhancer  575  may generate the definition of the composite media presentation from the MCIs of the selected template instance. In some embodiments, a composition presentation may be generated for each template instance prior to selection of a particular template instance. 
     In some embodiments, the definition of a composite media presentation may include the identity of the MCIs of the collection that are to be included in the presentation, the presentation order for the included MCIs, and/or a list of any suitable edit operations (e.g., transition operations, special effects, etc.) that may be performed to generate the composite presentations from the MCIs. In some embodiments, the MCIs of the composite media presentation can be identical to the MCIs of the template instance, or they can be MCIs that the media compositor may derive from the instance&#39;s MCIs. For example, multiple MCIs of a template instance can be still photos, where, for some or all of these still photos, collection enhancer  575  (e.g., video compositor  525 ) may generate a video clip in the composite generation by specifying a particular type of effect (e.g., a “Ken Burns” effect) for each of these photos. Also, from a video clip MCI of a template instance, the application can extract one or more video clips to include in the composite presentation. Similarly, from an MCI that is a burst-mode sequence, collection enhancer  575  may be operative to extract one or more still photos of the sequence and/or one or more types of video clips for one or more of the still photos of the sequence. Many other examples of deriving the composite-presentation with MCIs from a template instance&#39;s MCIs exist. 
     Collection enhancer  575  may be operative to generate composite media definitions by selecting a blueprint from a number of possible blueprints for the composite presentation. A blueprint may describe the desired transitions, effects, edit styles (e.g., including pace of the edits), and/or the like for a composite presentation. A blueprint can also specify the desired type of presentation, which can then influence the type of MCIs included or emphasized in the composite presentation. For example, one blueprint might specify highlights as the desired type of presentation, while another blueprint might specify retrospective as the desired type. For highlights, collection generator  505  or collection enhancer  575  may select the best MCIs that are representative of the MCIs of the template instance. For retrospectives, collection generator  505  or collection enhancer  575  may select the MCIs that are not necessarily of the whole set of MCIs of the template instance. In some embodiments, a blueprint may determine the duration of the composite presentation that collection enhancer  575  may generate. System  500  may be operative to specify the duration based on the amount of high-quality, unique content in the MCI collection of the template instance. For instance, in some embodiments, a blueprint&#39;s specified parameters (e.g., parameters specifying ideal duration for the MCIs) along with the MCIs that are selected may determine the desired duration of the composite presentation. In some embodiments, the blueprint might also specify other suitable parameters. 
     A type of a relevant particular interest (e.g., a particular interest that may result in a collection of MCIs being defined by process  600 ) for an MCI collection of the template instance may be used by collection enhancer  575  to determine which blueprint of the available blueprints is to be used for defining the composite presentation. For example, continuing with an example referred to above where a “dog” may be a particular interest that may be identified as relevant so as to be used to define an MCI collection, that particular interest of “dog” may be utilized by system  500  (e.g., by collection enhancer  575 ) to determine automatically the generation of the composite generation in any suitable way(s) (e.g., to choose a particular type of blueprint (e.g., a blueprint associated with a happy mood or a sentimental mood) for a “dog” particular interest and to choose a different type of blueprint (e.g., a blueprint associated with an extreme mood) for a “skydiving” particular interest. 
     In some embodiments, collection enhancer  575  may be operative to provide the particular duration of time for the composite presentation to audio compositor  530 , after such a duration may have been selected by a user and/or mood and/or keyword and/or blueprint. Based on the received duration, audio compositor  530  may dynamically define a composite audio presentation to accompany the composite media presentation of video compositor  525 . Audio compositor  530  may dynamically define an audio presentation to include several audio segments (e.g., of one or more of the MCIs and/or from audio library  555 ) in a particular sequence, and a set of edits and transitions between the audio segments in the sequence. In some embodiments, the audio segments are part of one song, while in other embodiments, they can be part of two or more songs. These audio segments may be referred to as body segments to signify that they are parts of another song. In some embodiments, audio compositor  530  may also select an ending segment from several candidate ending segments for the composite audio presentation. Audio compositor  530  may select a starting segment from several starting segments for the composite audio presentation. An editor may define a body, starting and ending segments from one or more songs by using any suitable audio authoring tools. 
     When an MCI collection is associated with a particular relevant interest, that interest may be used by audio compositor  530  to determine an appropriate song or collection of songs to be used to generate at least a portion of an audio portion of composite presentation. In some particular embodiments, a particular blueprint may be selected based on a particular interest associated with the MCI collection, where the particular blueprint may be associated with a number of different possible songs, and a particular one or more of the different possible songs may be selected for the particular blueprint based on the particular interest associated with the MCI collection. Alternatively, no matter how a blueprint may be selected, one or more songs to be used for defining a composite presentation with the selected blueprint may be selected based on one or more valid keywords associated with the MCI collection. The group of available songs from which collection enhancer  575  (e.g., audio compositor  530 ) may select one or more songs (e.g., from audio library  555 ) may be any suitable collection of songs, which may be a particular curated list of music for collection enhancer  575  or may be any suitable song from a library of songs available to system  1  (e.g., a user&#39;s personal music collection available to system  1 ). Each song may be associated with any suitable metadata that may be used by collection enhancer  575  in order to select an appropriate one or more songs based on any valid relevant interest associated with the MCI collection. For example, lyric metadata and/or song title metadata and/or artist metadata and/or tempo metadata and/or song style metadata and/or the like may be compared with the interest type to identify one or more songs to use for generating one or more composite presentations for the MCI collection. For example, a relevant interest of “dog” may be operative to enable collection enhancer  575  to identify and select a dog-themed song for use with the composite presentation. 
     After collection enhancer  575  may generate a definition of the composite presentation (e.g., after video compositor  525  may generate a definition for a video/media presentation, and after audio compositor  530  may generate a definition for an audio (e.g., song) presentation), the generated presentation definition(s) may be stored in storage (e.g., video/media presentation definition(s) in storage  560  and audio (e.g., song) presentation definition(s) in storage  565 , although in some embodiments one storage (e.g., one file) may be used for both video and audio definitions). Rendering engine  535  may then retrieve the definition(s) and generate a rendered composite presentation from the definition(s), which may then be output to a frame buffer of the system for presentation. One of ordinary skill will realize that system  500  may operate in any other suitable manner, such as, instead of defining a composite presentation for a template instance after a user selects a particular instance and/or mood and/or duration, system  500  may defines the composite presentation for some or all appropriate MCI collections in advance of receive any user selection. For instance, in some embodiments, the system may identify a subset of composite presentations that should initially be concurrently represented on a UI layout, and to identify an order of summary panes for those composite presentations on the UI layout. Alternatively, some embodiments may render the composite presentations before generating the UI layout, while still other embodiments may define a portion of a composite presentation before the UI layout is generated, and then may generate the rest of the definition of the composite presentation after the UI layout is generated. 
     In some embodiments, after a user selects a particular MCI collection of a particular template instance, system  500  may direct collection enhancer  575  to generate, for the selected template instance, the definition of the composite presentation. To generate the definition of the media composite presentation, collection enhancer  575  may automatically pick a mood for the composite presentation based on any suitable available data, including one or more identified relevant interests associated with the MCI collection. After picking the mood, collection enhancer  575  may select from a number of different blueprints a particular blueprint for the composite presentation based on the picked mood. The blueprint may describe any suitable characteristics of the presentation to be generated based on the blueprint, including, but not limited to, the desired transitions, effects, edit styles (e.g., including pace of the edits), the desired type of presentation, and/or the like, where one or more of such characteristics may vary between different blueprints. Collection enhancer  575  may select a subset or all of the MCIs of the MCI collection based on the picked mood and/or the selected blueprint for use in generating the composite presentation. Collection enhancer  575  may select a particular duration of time for the composite presentation based on the picked mood and/or the selected blueprint and/or the selected MCIs for use in generating the composite presentation. In conjunction with the selected blueprint, which may specify the type of desired edits (e.g., fast transition edits, or slow transition edits), the selection of the subset of MCIs may allow collection enhancer  575  to automatically define the duration of the composite presentation without any user input. After computing the desired duration of the composite presentation, collection enhancer  575  may provide this duration to audio compositor  530  in order for audio compositor  530  to dynamically generate the definition of a song presentation that has this duration. As mentioned above, audio compositor  530  may be operative to generate this definition by exploring different combinations of body segments from one or more songs available songs, along with different possible starting and ending segments, where one or more songs may be selected from a collection of available songs based on one or more of any relevant particular interest associated with the MCI collection, the mood chosen for the presentation, the blueprint chosen for the presentation, and/or the duration of time chosen for the presentation. Then the video/media/audio presentation definitions may be synched and provided to rendering engine  535  that may generate a rendered composite presentation from these definitions. 
       FIG.  7    is a flowchart of an illustrative process  700  for analyzing media content of a media library (e.g., with a computing system). At operation  702  of process  700 , the computing system may access a plurality of media content items (MCIs) of a media library and metadata associated with the media library, wherein the metadata defines a plurality of moments, each moment of the plurality of moments is associated with a subset of MCIs of the plurality of MCIs, and each MCI of the subset of MCIs that is associated with a particular moment is associated with geographical metadata indicative of a geographic location within a particular geographic range associated with the particular moment and temporal metadata indicative of a time within a particular time range associated with the particular moment. At operation  704  of process  700 , the computing system may analyze the plurality of MCIs and the metadata by identifying a plurality of first person residence moments from the plurality of moments, wherein each first person residence moment of the plurality of first person residence moments is a moment of the plurality of moments that is associated with both a first person and a residence of the first person, and by identifying an interest that is associated with each one of a first number of first person residence moments of the plurality of first person residence moments, wherein the first number is greater than a threshold value. At operation  706  of process  700 , the computing system may define a collection of MCIs of the plurality of MCIs, wherein each MCI of the collection of MCIs is associated with a moment of the plurality of moments that is associated with both the first person and the interest. 
     It is understood that the operations shown in process  700  of  FIG.  7    are only illustrative and that existing operations may be modified or omitted, additional operations may be added, and the order of certain operations may be altered. 
       FIG.  8    is a flowchart of an illustrative process  800  for managing a media library with a computing system. At operation  802  of process  800 , the computing system may access a plurality of media content items (MCIs) of the media library and metadata associated with the media library, wherein the metadata defines a plurality of moments, each moment of the plurality of moments is associated with a subset of MCIs of the plurality of MCIs, and each MCI of the subset of MCIs that is associated with a particular moment is associated with temporal metadata indicative of a time within a particular time range associated with the particular moment. At operation  804  of process  800 , the computing system may analyze the plurality of MCIs and the metadata by identifying at least one person residence moment from the plurality of moments, wherein each person residence moment of the at least one person residence moment is a moment of the plurality of moments that is associated with a location intimately associated with a person identity, and by identifying an interest that is associated with at least one of the at least one person residence moment. At operation  806  of process  800 , the computing system may define a collection of MCIs of the plurality of MCIs, wherein each MCI of the collection of MCIs is associated with the identified interest. 
     It is understood that the operations shown in process  800  of  FIG.  8    are only illustrative and that existing operations may be modified or omitted, additional operations may be added, and the order of certain operations may be altered. 
       FIG.  9    is a flowchart of an illustrative process  900  for managing a media library with a computing system. At operation  902  of process  900 , the computing system may access a plurality of media content items (MCIs) of the media library. At operation  904  of process  900 , the computing system may identify, with the computing system, at least a threshold number of MCIs of the plurality of MCIs that are associated with both a particular person entity and a particular interest. At operation  906  of process  900 , the computing system may define a collection of MCIs of the plurality of MCIs, wherein each MCI of the collection of MCIs is associated with the particular interest. 
     It is understood that the operations shown in process  900  of  FIG.  9    are only illustrative and that existing operations may be modified or omitted, additional operations may be added, and the order of certain operations may be altered. 
     Moreover, one, some, or all of the processes described with respect to  FIGS.  1 - 9    may each be implemented by software, but may also be implemented in hardware, firmware, or any combination of software, hardware, and firmware. They each may also be embodied as machine- or computer-readable code recorded on a machine- or computer-readable medium. The computer-readable medium may be any data storage device that can store data or instructions which can thereafter be read by a computer system. Examples of such a non-transitory computer-readable medium (e.g., memory  104  of  FIG.  1   ) may include, but are not limited to, read-only memory, random-access memory, flash memory, CD-ROMs, DVDs, magnetic tape, removable memory cards, optical data storage devices, and the like. The computer-readable medium can also be distributed over network-coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. For example, the computer-readable medium may be communicated from one electronic device to another electronic device using any suitable communications protocol (e.g., the computer-readable medium may be communicated to electronic device  100  via any suitable communications circuitry  114  (e.g., as at least a portion of application  103 )). Such a transitory computer-readable medium may embody computer-readable code, instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave or other transport mechanism, and may include any information delivery media. A modulated data signal may be a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. 
     It is to be understood that any or each module of media management system  500  may be provided as a software construct, firmware construct, one or more hardware components, or a combination thereof. For example, any or each module of media management system  500  may be described in the general context of computer-executable instructions, such as program modules, that may be executed by one or more computers or other devices. Generally, a program module may include one or more routines, programs, objects, components, and/or data structures that may perform one or more particular tasks or that may implement one or more particular abstract data types. It is also to be understood that the number, configuration, functionality, and interconnection of the modules of media management system  500  are only illustrative, and that the number, configuration, functionality, and interconnection of existing modules may be modified or omitted, additional modules may be added, and the interconnection of certain modules may be altered. 
     At least a portion of one or more of the modules of media management system  500  may be stored in or otherwise accessible to device  100  in any suitable manner (e.g., in memory  104  of device  100  (e.g., as at least a portion of application  103 )) and/or to server  50 . Any or each module of media management system  500  may be implemented using any suitable technologies (e.g., as one or more integrated circuit devices), and different modules may or may not be identical in structure, capabilities, and operation. Any or all of the modules or other components of media management system  500  may be mounted on an expansion card, mounted directly on a system motherboard, or integrated into a system chipset component (e.g., into a “north bridge” chip). 
     Any or each module of media management system  500  may be a dedicated system implemented using one or more expansion cards adapted for various bus standards. For example, all of the modules may be mounted on different interconnected expansion cards or all of the modules may be mounted on one expansion card. With respect to media management system  500 , by way of example only, the modules of media management system  500  may interface with a motherboard or processor  102  of device  100  through an expansion slot (e.g., a peripheral component interconnect (“PCI”) slot or a PCI express slot). Alternatively, media management system  500  need not be removable but may include one or more dedicated modules that may include memory (e.g., RAM) dedicated to the utilization of the module. In other embodiments, media management system  500  may be at least partially integrated into device  100 . For example, a module of media management system  500  may utilize a portion of device memory  104  of device  100 . Any or each module of media management system  500  may include its own processing circuitry and/or memory. Alternatively, any or each module of media management system  500  may share processing circuitry and/or memory with any other module of media management system  500  and/or processor  102  and/or memory  104  of device  100 . Alternatively, any or each module of media management system  500  may share processing circuitry and/or memory of server  50  remote from device  100 . 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources to define a collection of media content items of a media library for a relevant interest. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, social network identifiers, home addresses, office addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information, etc.), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to improve the definition of a collection of media content items of a media library for a relevant interest with the electronic device. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the United States, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (“HIPAA”); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of location detection services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In addition to providing “opt in” or “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, the definition of a collection of media content items of a media library for a relevant interest can be made based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the device, or publicly available information. 
     While there have been described systems, methods, and computer-readable media for defining a collection of media content items of a media library for a relevant interest, it is to be understood that many changes may be made therein without departing from the spirit and scope of the subject matter described herein in any way. Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. 
     Therefore, those skilled in the art will appreciate that the invention can be practiced by other than the described embodiments, which are presented for purposes of illustration rather than of limitation.
