## Title
Recommending content based on intersecting user interest profiles

## Abstract

This technology may generate recommendations of relevant content, based on determining intersections among one or more user interest profiles of users, who interact either synchronously or asynchronously. This technology may retrieve interest profiles for particular users, determine intersections among all user interest profiles (or among individual content recommendations), and create a group interest profile, update the particular users' interest profiles based on the group interest profile created, and generate recommendations of content that is determined to be relevant based on the group interest profile. A user may select items from these recommendations of content, add the user-selected content recommendations to a common group pool, generate a group interest profile based on the common group pool, and generate recommendations of content based on the group interest profile. Scores for the recommendations of content may be calculated and the top scoring ones may be displayed to the users in the group.

## Background
BACKGROUND
The present disclosure relates to technology for recommending content based on user interest profiles. In particular, the present disclosure relates to technology for recommending content to users of an online community, based on determining one or more intersections (e.g., similarities in interest) among user interest profiles.
Online communities, for example, social networks, are becoming increasingly popular, providing users of the online communities with a virtual forum where they may interact and share space and content or otherwise communicate as desired. Users may share their views, interests, and activities via these online communities. They may participate in a virtual forum, either synchronously, in groups, to communicate in real-time (for example, to “video chat”) or to share activities (for example, to view video content), or otherwise interact with one another asynchronously in “chat” forums.
SUMMARY
In one innovative aspect, the present disclosure of the technology includes systems including a processor and a memory storing instructions that, when executed, cause the system to retrieve one or more user interest profiles, determine an intersection between the one or more user interest profiles, generate a group interest profile; and generate the content recommendations based on the group interest profile that is generated.
In general, another innovative aspect of the present disclosure includes a method, using one or more computing devices, for retrieving one or more user interest profiles; determining at least one intersection between the one or more user interest profiles; generating, a group interest profile; and generating recommendations of content based on the group interest profile.
Other implementations of one or more of these aspects include corresponding systems, apparatus, and computer programs, configured to perform the action of the methods, encoded on computer storage devices.
These and other implementations may each optionally include one or more of the following features.
i. For instance, the operations further include one or more of: 1) updating users' interest profiles based on the group interest profile; 2) generating content recommendations based on the group interest profile; 3) providing for display a prompt for users to select items from their content recommendations; 4) adding the user-selected content recommendations to a common group pool; 5) providing for display the content recommendations to the users of the group; 6) calculating scores for content recommendations; and 7) providing for display the top scoring content recommendations to the users in the group.
ii. For instance, the features include: a) each user interest profile corresponding to a user; 2) the group interest profile is based on the intersection between the one or more user interest profiles; 3) a user interface configured to provide for display a prompt for a user to select one or more user-selected content recommendations; 4) a selection prompt module for adding the one or more user-selected content recommendations to a common group pool; 5) a user interface configured to provide for display the one or more user-selected content recommendations to one or more users; 6) a scoring module for calculating scores for the content recommendations based on whether the content recommendations are relevant; and 7) a user interface configured to provide for display top scoring content recommendations to one or more users.
The systems and methods disclosed below are advantageous in a number of respects. With the ongoing trends and growth in social network communication, it may be beneficial to generate “common” user interest profiles from a group activity (users interacting either synchronously or asynchronously) and recommend content based on determining one or more intersecting user interest profiles. The systems and methods provide ways for suggesting content to a group interacting either synchronously or asynchronously as a whole. They provide ways to generate group interest profiles that define common interests for the group. They also provide ways by which the group interest profiles are compared to a universe of content to search for content that is suitable for a particular group, based on which recommendations of content are generated. They provide a user interface to allow individual users to indicate selections of particular content recommendations.

DETAILED DESCRIPTION
In some implementations, this technology includes systems and methods for generating recommendations of content for users, by determining intersecting user interest profiles. Specifically, this technology receives one or more user interest profiles from one or more users communicating synchronously or asynchronously (e.g., audio chat, video chat, instant messaging, etc.), and generates a group interest profile, based on determining one or more “intersecting” (e.g., with similarities) user interest profiles. In some instances, each user interest profile corresponds to a particular user and his or her individual or personal interests. The systems and methods of this technology determine the intersections between the one or more user interest profiles, and generate recommendations of appropriate or relevant content based on the intersecting user interest profiles. In some implementations, the systems and methods require users to manually select recommendations and generate recommendations of content based on user-selected recommendations. In some instances, the systems and methods generate one or more recommendations of content for one or more users, calculate scores for the one or more recommendations of content based on whether they are relevant to particular user interest profiles, and provide for display the top scoring recommendations of content to one or more members of a group of users.
In the following description, for purposes of explanation, numerous specific details are indicated in order to provide a thorough understanding of the technology described. This technology may be practiced without these specific details. In the instances illustrated, structures and devices are shown in block diagram form in order to avoid obscuring the technology. For example, the present technology is described with some implementations illustrated below with reference to user interfaces and particular hardware. However, the present technology applies to any type of computing device that can receive data and commands, and any devices providing services. Moreover, the present technology is described below primarily in the context of generating and providing recommendations of content, by determining intersecting user interest profiles; however, the present technology applies to any type of situation and may be used for other applications beyond generating and providing content. In particular, this technology may be used in other contexts besides providing recommendations of content.
Reference in the specification to “one implementation,” “an implementation,” or “some implementations” means simply that one or more particular features, structures, or characteristics described in connection with the one or more implementations is included in at least one or more implementations that are described. The appearances of the phrase “in one implementation or instance” in various places in the specification are not necessarily all referring to the same implementation or instance.
Some portions of the detailed descriptions that follow are presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory of either one or more computing devices. These algorithmic descriptions and representations are the means used to most effectively convey the substance of the technology. An algorithm as indicated here, and generally, is conceived to be a self-consistent sequence of steps leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.
It should be understood, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise, as apparent from the following discussion, it should be appreciated that throughout the description, discussions utilizing terms, for example, “processing,” “computing,” “calculating,” “determining,” “displaying,” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission, or display devices.
The present technology also relates to an apparatus for performing the operations described here. This apparatus may be specially constructed for the required purposes, or it may include a general-purpose computer selectively activated or reconfigured by a computer program stored in the computer. For example, a computer program may be stored in a computer-readable storage medium, for example, but not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, magnetic disks, read-only memories (ROMs), random access memories (RAMs), EPROMs, EEPROMs, magnetic or optical cards, flash memories including USB keys with non-volatile memory, or any type of media suitable for storing electronic instructions, each coupled to a computer system bus.
This technology may take the form of an entirely hardware implementation, an entirely software implementation, or an implementation including both hardware and software components. In some instances, this technology is implemented in software, which includes but is not limited to firmware, resident software, microcode, etc.
Furthermore, this technology may take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. For the purposes of this description, a computer-usable or computer-readable medium may be any apparatus that can include, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device.
A data processing system suitable for storing and/or executing program code includes at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements may include local memory employed during actual execution of the program code, bulk storage, and cache memories, which provide temporary storage of at least some program code in order to reduce the number of times code may be retrieved from bulk storage during execution.
Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) may be coupled to the system either directly or through intervening I/O controllers.
Communication units including network adapters may also be coupled to the systems to enable them to couple to other data processing systems, remote printers, or storage devices, through either intervening private or public networks. Modems, cable modems, and Ethernet cards are just a few examples of the currently available types of network adapters.
Finally, the algorithms and displays presented in this application are not inherently related to any particular computer or other apparatus. Various general-purpose systems may be used with programs in accordance with the teachings here, or it may prove convenient to construct more specialized apparatus to perform the required method steps. The required structure for a variety of these systems is outlined in the description below. In addition, the present technology is not described with reference to any particular programming language. It should be understood that a variety of programming languages may be used to implement the technology as described here.
FIG. 1 is a high-level block diagram illustrating some implementations of systems for generating recommendations of content based on generating a group interest profile. The system 100 illustrated in FIG. 1 includes system architecture (distributed or other) for generating recommendations of content based on a group interest profile. The system 100 includes one or more social network servers 102a, 102b, through 102n, that may be accessed via user devices 115a through 115n, which are used by users 125a through 125n, to connect to any one of the social network servers 102a, 102b, through 102n. These entities are communicatively coupled via a network 105. Although only two user devices 115a through 115n are illustrated, any numbers of user devices 115n may be used by any number of users 125n. 
Moreover, while the present disclosure is described below primarily in the context of providing a framework for providing recommendations of content by generating a group interest profile, the present disclosure may be applicable to other situations where generating recommendations of content for any purpose that is not related to a group interest profile, may be desired. For ease of understanding and brevity, the present disclosure is described in reference to generating recommendations of content based on creating a group interest profile.
The user devices 115a through 115n in FIG. 1 are illustrated simply as one example. Although FIG. 1 illustrates only two devices, the present disclosure applies to any system architecture having one or more user devices 115, therefore, any number of user devices 115n may be used. Furthermore, while only one network 105 is illustrated as coupled to the user devices 115a through 115n, the social network servers, 102a-102n, the profile server 130, the web server 132, third party servers 134a through 134n, and the content-item server 136, in practice, any number of networks 105 may be connected to these entities. In addition, although only two third party servers 134a through 134n are shown, the system 100 may include any number of third party servers 134n. 
In some implementations, the social network server 102a is coupled to the network 105 via a signal line 110. The social network server 102a includes a social network application 104, which includes the software routines and instructions to operate the social network server 102a and its functions and operations. Although only one social network server 102a is described here, multiple servers may be present, as illustrated by social network servers 102b through 102n, each with functionality similar to social network server 102a or different.
The term “social network” as used here includes, but is not limited to, any type of social structure where the users are connected by a common feature or link. The common feature includes relationships/connections, e.g., friendship, family, work, a similar interest, etc. The common features are provided by one or more social networking systems, such as those included in the system 100, including explicitly-defined relationships and relationships implied by social connections with other online users, where the relationships form the social graph 108.
The term “social graph” as used here includes, but is not limited to, a set of online relationships between users, such as provided by one or more social networking systems, such as the social network system 100, including explicitly-defined relationships and relationships implied by social connections with other online users, where the relationships form a social graph 108. In some examples, the social graph 108 may reflect a mapping of these users and how they are related to one another.
The social network server 102a and the social network software/application 104 as illustrated are representative of a single social network. Each of the plurality of social network servers 102a, 102b through 102n, may be coupled to the network 105, each having its own server, application, and social graph. For example, a first social network hosted on a social network server 102a may be directed to business networking, a second on a social network server 102b directed to or centered on academics, a third on a social network server 102c (not separately shown) directed to local business, a fourth on a social network server 102d (not separately shown) directed to dating, and yet others on social network server (102n) directed to other general interests or perhaps a specific focus.
A profile server 130 is illustrated as a stand-alone server in FIG. 1. In other implementations of the system 100, all or part of the profile server 130 may be part of the social network server 102a. The profile server 130 is connected to the network 105 via a line 131. The profile server 130 has profiles for all the users that belong to a particular social network 102a-102n. One or more third party servers 134a through 134n are connected to the network 105, via signal line 135. A web server 132 is connected, via line 133, to the network 105.
The content-item server 136 is illustrated as a stand-alone server in FIG. 1. In some implementations, the content-item server 136 delivers items that are recommended as well as metadata relating to those items. The content-item server 136 provides the items recommended for display to users.
The social network server 102a includes a group interest profile application 106a, to which user devices 115a through 115n are coupled via the network 105. In particular, user device 115a is coupled, via line 114a, to the network 105. For example, the user 125a may use the user device 115a to access the group interest profile application 106a to view recommendations of content for personal or group use. The group interest profile application 106 or certain components of it may be stored in a distributed architecture in any of the social network server 102, the third party server 134, and the user device 115. In some implementations, the group interest profile application 106 may be included, either partially or entirely, in any one or more of the social network server 102, the third party server 134, and the user device 115.
The user devices 115a through 115n may be a computing device, for example, a laptop computer, a desktop computer, a tablet computer, a mobile telephone, a personal digital assistant (PDA), a mobile email device, a portable game player, a portable music player, a television with one or more processors embedded in the television or coupled to it, or any other electronic device capable of accessing a network.
The network 105 may be of conventional type, wired or wireless, and may have any number of configurations such as a star configuration, token ring configuration, or other configurations known to those skilled in the art. Furthermore, the network 105 may comprise a local area network (LAN), a wide area network (WAN, e.g., the Internet), and/or any other interconnected data path across which one or more devices may communicate.
In some implementations, the network 105 may be a peer-to-peer network. The network 105 may also be coupled to or include portions of one or more telecommunications networks for sending data in a variety of different communication protocols.
In some instances, the network 105 includes Bluetooth communication networks or a cellular communications network for sending and receiving data such as via short messaging service (SMS), multimedia messaging service (MMS), hypertext transfer protocol (HTTP), direct data connection, WAP, email, etc.
In some implementations, the social network servers, 102a-102n, the profile server 130, the web server 132, and the third party servers 134a through 134n are hardware servers including a processor, memory, and network communication capabilities. One or more of the users 125a through 125n access any of the social network servers 102a through 102n, via browsers in their user devices and via the web server 132.
As one example, in some implementations of the system, the interest profiles of particular users (125a through 125n) of a social network 102a through 102n may be retrieved from the social graph 108. In addition, information to generate one or more of the users' individual recommendations of content is retrieved. It should be noted that any information that is retrieved for particular users is only upon obtaining the necessary permissions from the users, in order to protect user privacy and any sensitive information of the users. The group interest profile application 106a generates recommendations of content for group members.
FIG. 2 is a block diagram illustrating some implementations of a social network server 102a through 102n and third party server 134a through 134n, system 200 including a group interest profile application 106a/106c. In FIG. 2, like reference numerals have been used to reference like components with the same or similar functionality that has been described above with reference to FIG. 1. Since those components have been described above that description is not repeated here. The system 200 generally includes one or more processors, although only one processor 235 is illustrated in FIG. 2. The processor is coupled, via a bus 220, to memory 237 and data storage 239, which stores any information related to content recommendations and/or interest profiles, received from any of the other sources identified above. In some instances, the data storage 239 is a database organized by a user or a group of users. In some instances, the group interest profile application is stored in the memory 237.
A user 125a, via a user device 115a, may view the recommendations of content and/or may add recommendations of content to an “interest” profile, via the communication unit 241. The group interest profile applications 106a and 106c may reside, in their entirety or parts of them, in the user's device (115a through 115n), in the social network server 102a (through 102n), or, in a separate server, for example, in the third party server 134 (FIG. 1). The user device 115a communicates with the social network server 102a using the communication unit 241, via signal line 110.
Referring now to FIG. 3, like reference numerals have been used to reference like components with the same or similar functionality that has been described above with reference to FIGS. 1 and 2. Since those components have been described above that description is not repeated here. An implementation of the group interest profile application 106, indicated in FIG. 3 by reference numeral 300, includes various applications or engines that are programmed to perform the functionalities described here. The profile management module 301 manages a user's (one or more users) individual profile information including the user's “interest” profile. The permission module 303 obtains permission to obtain user information on users and other information relevant to user interest profiles and/or content recommendations. The profile retrieving module 305 retrieves user profile information including the user interest profiles. The intersection determination module 307 determines the intersections (one or more) between one or more user interest profiles. The group interest profile module 309 generates a group interest profile based in part on the one or more user interest profiles. The content recommendation module 311 generates content recommendations based on the group interest profile. The selection prompt module 313 generates a user prompt for receiving content recommendations from one or more users. The scoring module 315 calculates a specific score for a recommendation of content based in part on determining a relevancy factor (for example, how relevant particular content may be to a particular user) of the one or more user interest profiles. The user interface module 317 generates a user interface for providing displays of user interest profiles or recommendations of content or both.
The group interest profile applications 106a and 106c include applications or engines that communicate over the software communication mechanism 320. Software communication mechanism 320 may be an object bus (such as CORBA), direct socket communication (such as TCP/IP sockets) among software modules, remote procedure calls, UDP broadcasts and receipts, HTTP connections, function or procedure calls, etc. Further, any or all of the communication could be secure (SSH, HTTPS, etc.). The software communication may be implemented on any underlying hardware, such as a network, the Internet, a bus 220 (FIG. 2), a combination thereof, etc.
The profile management module 301 manages a user's individual profile information including the user's interest profile. In some implementations, the profile management module 301 may either add, delete, or modify (or perform more than one or all of these tasks) information relating to a user profile (e.g., name, birthdate, occupation, employer, education, gender, email, phone number, street address, posts, photos, videos, etc.).
The permission module 303 obtains permission for obtaining user information on users and other information relevant to user interest profiles and/or recommendations of content. The permission module 303 makes certain that the user device is compliant with protocols and any privacy concerns and that any information that is obtained from a user is only after the user is provided notice and/or user consent is obtained.
The profile retrieving module 305 retrieves user profile information. The profile retrieving module 305 retrieves information from one or more users interacting synchronously or asynchronously (e.g., audio chat, video chat, instant messaging, etc.) including the user's interest profile.
The intersection determination module 307 determines the intersection between one or more user interest profiles. The intersection determination module 307 retrieves one or more user's interest profiles and determines the intersections between them. In some implementations, the intersection determination module 307 determines one or more intersections based in part on similar elements in the user interest profiles. For example, one or more users may indicate that they attended the “Good Old School” and therefore, the intersection determination module 307 determines the “Good Old School” is an intersection (similar interest) among the one or more users that are illustrated. In some instances, the intersection determination module 307 determines intersections between one or more recommendations of content.
The group interest profile module 309 generates a group interest profile, based in part on, considering the one or more user interest profiles. In some implementations, the group interest profile module 309 retrieves one or more user interest profiles from the profile retrieving module 305 and the intersection information between the one or more user interest profiles from the intersection determination module 307. The group interest profile module 309 then creates a group interest profile including the intersecting information between the one or more user interest profiles.
The content recommendation module 311 generates recommendations of content based on the group interest profile. The content recommendation module 311 retrieves one or more user interest profiles from the profile retrieving module 305 and the intersection information between the one or more user interest profiles from the intersection determination module 307 and generates one or more recommendations of content based on the group interest profile and intersection information. In some implementations, the recommendations of content include any type of content that a user may be interested in or may wish to become aware of (e.g., advertisements, webpages, music, video, books, products, etc.).
The selection prompt module 313 generates a user prompt for requesting and receiving recommendations of content from one or more users. The selection prompt module 313 generates a user interface for display and one or more users may decide to share their “personal” content with a group, by an indication of either acknowledging, approving, and/or consuming content. For example, a user may indicate that he/she has attended (or will be attending) the “Good Old School” class reunion (e.g., by clicking an “Add” button—as indicated by the two “Add” buttons that are illustrated for user 125 in FIG. 10). This indication may then be shared with the group interest profile module 309 (along with any number of other indications of consumption from other users), which generates a group interest profile based on indications of the content consumed by the users. Then, the content recommendation module 311 may generate one or more content recommendations based on the group interest profile generated, to recommend content consumed by some users to other users.
The scoring module 315 calculates a score (from a range of scores) for a particular recommendation of content based in part on determining if the recommendations of content are relevant to the one or more user interest profiles by calculating a combination of scores from each of the interest profiles. The scoring module 315 receives one or more recommendations of content from the content recommendation module 311 and the scoring module 315 generates a score for the one or more recommendations of content. For example, consider a set of N users 125a, 125b, . . . 125N interacting synchronously or asynchronously (e.g., video, audio, text, etc.). Each user has a corresponding interest profile 810a, 810b, . . . 810N. Each interest profile may be independently used to generate sets of recommendations of content for each user R1, R2, . . . Rn. Each set R1 through Rn (n being the number of sets of recommendations) may then be ranked by each model 810a through 810N. This results in a matrix of scores S of size N|R|×N (N being the total number of users/models). The score for a particular item may be some function (e.g., average, max, median, etc.) of the scores assigned to it by each of the N models. In some implementations, an item may appear in multiple users' recommendation lists and in these instances, its score would increase appropriately. In some implementations, the score is based in part on determining how relevant the recommendations of content may be to the one or more users. For example, a recommendation of content may be for the “Good Old School” class reunion, which is attended by one or more users in the group designated as the “Good Old School.” Therefore the “Good Old School” class reunion recommendations of content receive a higher score. Inversely, in some instances, one recommendation of content may be for deep sea fishing and it may be determined that none (or very few) of the users live close to the ocean. Therefore, a recommendation of content relating to deep sea fishing content may receive a lower score.
The user interface module 317 may generate a user interface for display of user interest profiles and/or content recommendations. For example, the user interface module 317 may generate the user interface for display of recommendations of content and user profiles including one or more of a user name, photos, videos, posts, personal information, etc. In some implementations, the user interface module 317 displays the user prompt for a user to select one or more recommendations of content. In some instances, the user interface module 317 displays the one or more user-selected recommendations of content to one or more users. In some implementations, the user interface module 317 displays the “top” scoring recommendations of content (from the scoring module 315) to one or more users.
FIG. 4 is a flow chart illustrating an example method indicated by reference numeral 400 for generating recommendations of content for a group. In the example method illustrated, one or more operations may include retrieving a group of users interacting synchronously or asynchronously (e.g., video, audio, text, etc.), as illustrated by block 402. The method 400 then proceeds to the next block 404 and may include one or more operations to obtain permission from one or more users to use their profile information. The method 400 then proceeds to the next block 406 and may include one or more operations to retrieve corresponding user interest profiles for the one or more users. The method 400 then proceeds to the next block 408 and may include one or more operations to determine intersections between user interest profiles. The method 400 then proceeds to the next block 410 and may include one or more operations to generate a group interest profile based on the intersections that are determined between the user interest profiles. From there, the method 400 then proceeds to the next block 412 and may include one or more operations to update user interest profiles based on creating the group interest profile. The method 400 then proceeds to the next block 414 and may include one or more operations to generate content recommendations based on the group interest profile.
FIG. 5 is a flow chart illustrating an example method indicated by reference numeral 500, for generating recommendations of content for a group based on generating a group profile. In the method illustrated, operations may include retrieving a group of users who interact either synchronously or asynchronously (e.g. video, audio, text, etc.) as indicated by block 502. The method 500 then proceeds to the next block 504 and may include one or more operations to obtain permission for users to use their profile information. The method proceeds to the next block 506, at which stage, one or more operations may retrieve users' corresponding interest profiles. From that point, the method proceeds along one path, to the next block 508, at which stage, one or more operations include determining the intersections (e.g., similarities) between one or more interest profiles. The method proceeds to the next block 510, at which stage, one or more operations include generating a group interest profile, by determining an intersection between one or more interest profiles. The method proceeds to the next block 512, at which point, one or more operations of the method that are optional (as shown by broken lines around block 512) include updating one or more users' interest profiles based on the group interest profile. The method proceeds to the next block 512, at which point, one or more operations of the method include updating one or more users' interest profiles based on the group interest profile.

The example method 700 then proceeds to the next block 714, at which stage, it may include one or more operations that are optional (as shown by broken lines around block 714) to update a user's interest profile, based on the “top” scoring recommendations of content. The example method 700 then proceeds to the next block 716 and may include one or more operations to provide displays of “top” scoring content recommendations to all users in the group.
FIG. 8 illustrates some instances of intersecting user interest profiles. In FIG. 8, there are three particular examples of intersecting user interest profiles. As one example, an interest profile for a particular user, “User 1” (indicated by reference numeral 810a), includes a plurality of interests, for example, a gaming interest (indicated by reference numeral 820a), an interest in the state of Utah (indicated by reference numeral 820b), an interest in a “Good Old School,” indicated by reference numeral 820e, an interest in climbing, indicated by reference numeral 820f, and an interest in hiking, indicated by reference numeral 820g. As another example, an interest profile for another particular user, “User 2” (indicated by reference numeral 810b), includes a plurality of diverse interests, for example, an interest in the state of Utah indicated by reference numeral 820b, an interest in a “Good Old School,” indicated by reference numeral 820e, an interest in biking, indicated by reference numeral 820c, an interest in running, as indicated by reference numeral 820d, and an interest in martial arts, as indicated by reference numeral 820h. As yet another example, an interest profile for another particular user, “User 3” (indicated by reference numeral 710c), may include an interest in a “Good Old School” indicated by reference numeral 820e, an interest in martial arts, indicated by reference numeral 820h, an interest in climbing, as indicated by reference numeral 820f, an interest in hiking, as indicated by reference numeral 820g, an interest in movies, as indicated by reference numeral 820j, and an interest in the state of Colorado, as indicated by the reference numeral 820h. 
There is an intersection of interests between users “User 1” and “User 2.” Both users share an interest in the state of “Utah.” The shared interest in “Utah,” indicated by reference numeral 820b, lies in the intersection between the interest profile for “User 1” (810a) and the interest profile (810b) for “User 2.” The interest in martial arts indicated by reference numeral 820h falls within an intersection between the interest profile (810b) for “User 2” and the interest profile (810c) for “User 3.” The interest in climbing (8200 and the interest in hiking (820g) lie within the intersection between the interest profiles of “User 1” (810a) and “User 3” (810c.) The interest in “Good Old School” (820e) falls within an intersection between the interest profiles of “User 1” (810a) and “User 2” (810b) and the interest profile of “User 3” (810c).
FIG. 9 illustrates some instances of user interest profiles and some examples of their corresponding scores. FIG. 9, illustrates the interest profile for “User 1,” indicated by reference numeral 810a, the interest profile for “User 2,” indicated by reference numeral 810b, and the interest profile for “User 3,” indicated by reference numeral 810b. Each of the user interest profiles in FIG. 9 may be similar to those illustrated in FIG. 8. As the user interest profiles and intersections have been described above, that description is not repeated here. FIG. 9 also illustrates an example scoring table 920. The scoring table 920 illustrates one example of scoring of interests of users. For example, one or more interests that are determined to be within a user's interest profile may be assigned a higher score than interests that are not within a user's profile (e.g., running is designated a higher score for “User 2” than for “User 1” or for “User 3”). In another example, the “Good Old School” recommendation is assigned higher scores for each of the users “User 1,” “User 2,” and “User 3,” in the scoring table 920 because the interest profile for “User 1” (810a), the profile interest for “User 2” (810b), the interest profile for “User 3” (810c) all include the “Good Old School” interest 820e. FIG. 9 also illustrates one example of a scoring guide 930. In this example, the scoring guide 930 illustrates a scale of scores ranging from 0 to 9—where scores of 9-7 indicate recommendations of content that are determined to be “relevant” to a particular user, scores of 6-3 for recommendations of content that are determined to be “somewhat relevant” to a particular user, and scores of 2-0 for recommendations of content that are determined to be “not relevant” to a particular user.
FIG. 10 illustrates some implementations of a graphical user interface for sharing personal recommendations with a group shared content list. FIG. 10 illustrates user personal content 1010, a group shared content list 1020, and a group interest profile 1030. The user personal content 1010 includes one or more recommendations of content that is personalized for one or more users. Each individual user (e.g., user 125a, user 125b, and user 125c) may select an “add” button, and add that particular recommendation to the group shared content list 1020. The group shared content list 1020 includes the one or more recommendations of content shared by one or more users and are sent to the group interest profile module 309 to determine a group interest profile 1030 based on the group shared content list 1020.
