Title: Displaying content items related to a social network group on a map

Description:
FIELD 
     The subject technology generally relates to social networking software and, in particular, relates to a system and method for displaying content items related to a social network group. 
     BACKGROUND 
     Social networking services are designed, in part, to store and provide information about the social contacts of a user. Oftentimes, social network groups are provided within social networking services to provide information about a defined group of people, such as a family, members of a club, alumni of a university, etc. One purpose of social network groups is to store interesting content items about the interactions between members in the groups. For example, a family group might find the fact that two adult brothers had dinner together interesting. When displaying a webpage of a social network group, a web browser may display a plurality of content items associated with the social network group, such as photographs, videos, business reviews or articles. The plurality of content items may be arranged in an arbitrary order or a ranked order, where the ranking is based on chronology or interest level. One drawback of this scheme is that the arrangement of content items is not presented in a manner designed to optimize the interaction of the user with the content items. As the foregoing illustrates, a technique to display content about a social network group in a meaningful format may be desirable. 
     SUMMARY 
     The disclosed subject matter relates to a computer-implemented method for presenting social content on a map. The method includes receiving a new content item. The new content item is not associated with a social network group including a set of subject members and a set of viewing members. The method also includes determining that the new content item is related to the social network group. The method also includes storing the new content item in association with the social network group. The method also includes associating the new content item with a geographic location. The method also includes providing for display a map and an indication of the social network group. The map includes a representation of the new content item.

     DETAILED DESCRIPTION 
     The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be clear and apparent to those skilled in the art that the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. 
     The subject technology is related to approaches for presenting social content on a map. One technique involves receiving a new content item, such as an image, a video, an article, a text, audio or video chat room interface, contents of a chat or messaging session, a status update, a geographic check-in or a calendar event. The new content item is not associated with a social network group that includes a set of subject members and a set of viewing members. The technique also involves determining that the new content item is related to the social network group. The new content item may be related to the social network group if the new content item is associated with at least two subject members of the social network group, for example, if two subject members are mentioned in the new content item or indicated a preference for the new content item. The technique also involves storing the new content item in association with the social network group. The technique also involves associating the new content item with a geographic location. The geographic location may be included in the new content item. For example, some photographs and videos include geographic codes indicating a geographic location. Alternatively, the geographic location may be derived based on a point of interest name included in the new content item. For example, the new content item may include a review of a business, and the geographic location may correspond to the physical address of the business. The technique also involves generating a map including the geographic location. The map includes a representation of the new content item. The representation of the new content item is positioned on the map proximate to the geographic location on the map. For example, the representation of the new content item may overlay the map at the geographic location. The technique also involves providing for display a representation of the map and an indication of the social network group. For example, the map may be displayed on a webpage of the social network group. 
       FIG. 1  illustrates an example of a computer system  100  configured to implement displaying content items related to a social network group. 
     As shown, the computer system  100  includes a database  110 , a content presentation server  120 , and a client computing device  130 . The database  110 , content presentation server  120 , and client computing device  130  may be configured to communicate with one another via a network, such as the Internet, an intranet or a cellular network or via a wired or wireless connection. 
     The database  110  is configured to store content or data to be presented by the content presentation server  120 . The database  110  is described in more detail in conjunction with  FIGS. 2-3 , below. While one database  110  is illustrated here, persons skilled in the art will recognize that the techniques disclosed herein may be implemented with multiple databases  110 . 
     The content presentation server  120  is configured to receive content from the database  110  and to provide or transmit for display the content that is received from the database  110  to the client computing device  130 . The content presentation server  120  is described in more detail in conjunction with  FIG. 4 , below. While one content presentation server  120  is illustrated here, persons skilled in the art will recognize that the techniques disclosed herein may be implemented with multiple content presentation servers  120 . Furthermore, the content presentation server  120  and the database  110  may be implemented in the same machine or in different machines. 
     The client computing device  130  may be any computing device capable of displaying content, such as photographs, videos, articles or comments, to a user. The client computing device  130  may be a laptop computer, a desktop computer, a mobile phone, a personal digital assistant (PDA), a tablet computer, a netbook, a physical machine or a virtual machine. Persons skilled in the art will recognize other devices that could implement the functionalities of the client computing device  130 . The client computing device  130  may include one or more of a keyboard, a mouse, a touch screen, and a display to allow the user to interact with the content. Furthermore, while only one client computing device  130  is illustrated here, persons skilled in the art will recognize that the techniques disclosed herein may be implemented with multiple client computing devices  130 . 
       FIG. 2  illustrates an example of the database  110  of  FIG. 1  in more detail. 
     As shown, the database  110  includes a processor  202 , a network interface  204 , and a memory  206 . The processor  202  is configured to execute computer instructions that are stored in a computer-readable medium, such as the memory  206 . For example, the processor  202  may be a central processing unit (CPU). The network interface  204  is configured to allow the database  110  to transmit and receive data in the network. The network interface  204  may include one or more network interface cards (NICs). The memory  206  stores data and instructions. As illustrated, the memory  206  stores information associated with one or more social network groups  208  and a plurality of content items  220 ,  222 ,  224 , and  226  external to the social network group. 
     The information associated with the social network group  208  may include an identification of one or more viewing members  210  and an identification of one or more subject members  212 . The information associated with the social network group  208  may be, for example, a symmetric social network group, an asymmetric social network group, an individual profile or a combination of two or more individual profiles. The viewing members  210  may be identical to the subject members  212 . Alternatively, the set of viewing members  210  may include the set of subject members  212 , meaning that all subject members  212  are also viewing members  210  but some viewing members  210  may not be subject members  212 . In one example, the set of viewing members  210  may be different from the set of subject members  212  to the degree that at least one subject member  212  is not a viewing member  210 . For example, a social circle may have multiple subject members  212  and single viewing member  210  who created the social circle. An individual profile may have a single subject member  212  who created the individual profile and multiple viewing members  210  who are acquaintances of the subject member  212 . Symmetric social network groups, for example a family group or a university alumni group, may have identical viewing members  210  and subject members  212 . 
     Social circles are one example of asymmetric social network groups. As used herein, “social circles” are categories to which a user can assign his/her social networking contacts and better control the distribution and visibility of social networking messages. A social circle is a social network group that may have a set of subject members  212  that includes these contacts. In accordance with the subject disclosure, a social circle is provided as a data set defining, in the set of subject members  212 , a collection of contacts that are associated with one another. A social circle can be described from the perspective of an individual viewing member  212  that is the center of a particular collection of socially interconnected people, or from the aggregate perspective of a collection of socially interconnected people. A social circle can have narrowly defined boundaries, all of the members of the social circle may be familiar with one another, and permission may be required for a member to join asocial circle. A user of an electronic device may define a social circle, and the social circle, as a data set defining a collection of contacts, may reflect a real-life social circle of the user. A social circle may have a single viewing member  210  and multiple subject members  212 . 
     For example, a user of an electronic device may have different groups of friends, coworkers and family, and there may be some overlap among those groups (e.g., a coworker who is also considered to be a friend, a family member who is also a coworker). Through the creation and use of social circles, the user can organize and categorize social networking contacts into various different groupings. Other examples of social network groups may include a group of users in a computer or mobile phone-based chat session, for example, a short message service (SMS) chat session or an instant messaging (IM) chat session, an individual profile in a social networking service, or a combination of two or more individual profiles in the social networking service. 
     The information associated with social network group  208  may also include content items  214 ,  216 , and  218  that are associated with the social network group and stored within the information associated with the social network group  208 . Each content item  212 ,  216  or  218  may include one or more photographs, videos, articles, text, audio or video chat room interfaces, status updates, geographic check-ins, current locations of mobile devices or reviews of points of interest, such as businesses. Content items may be added to the information associated with the social network group  208  by one or more of the subject members  212 . 
     Additional content items  220 ,  222 ,  224 , and  226  may be stored outside the information associated with the social network group  208 . The additional content items  220 ,  222 ,  224 , and  226  may not be associated with the social network group. 
     Some content items may be associated with a geographic location that may be presented on a map. The geographic location may correspond to a geographic point of interest, such as a business or a park, situated at the geographic location. The point of interest may be derived from the geographic location or vice versa. For example, a business may correspond to a geographic location or a geographic location may correspond to a business. The geographic location may be included in the content item. For example, photographic and video content items taken by some cameras may include a geographic code that corresponds to a location. 
     Alternatively, the geographic location may be derived based on the content item or based on a point of interest name included in the content item. For example, if the content item is a review of a restaurant that includes the name of the restaurant, the corresponding geographic location may be the address of the restaurant, which may be stored in database  110  or another database. Some content items, for example chat rooms or photographs lacking any geographic indication, may lack a location. The content items may be provided to database  110  by users of the social networking service. Alternatively, the content items may be gathered from sources external to the database  110  using, for example, a web crawler. However, users of the social networking service may opt out of having data about the user gathered from sources external to the social networking service being brought into the social networking service. In one implementation, the user may indicate that he/she wishes to opt out of having such data brought into the social networking service by modifying his/her account settings with the social networking service. 
       FIG. 3  illustrates an example of data that may be stored in the database memo  206  of  FIG. 2  in more detail. 
     As shown, the database memory  206  includes an “individual profile of Alice Bitdiddle”  310 , an “individual profile of Ben Bitdiddle”  320 , and a “social network group of the Bitdiddle family”  330 , all of which are associated with a social networking service. Alice Bitdiddle and Ben Bitdiddle are the only subject members  212  and the only viewing members  210  of the Bitdiddle family social network group  330 . In addition, the user Alice Bitdiddle has permission to view one or more content items  325  in the individual profile of Ben Bitdiddle  320 , and the user Ben Bitdiddle has permission to view one or more content items  315  in the individual profile of Alice Bitdiddle  310 . The individual profiles of Alice Bitdiddle  310  and Ben Bitdiddle  320 , as well as the social network group of the Bitdiddle family  330  include content items, for example content items  315 ,  325 , and  335 . Some contents items  315  within Alice Bitdiddle&#39;s profile  310  are associated with the individual profile of Alice Bitdiddle  310  only. Some content items  325  within Ben Bitdiddle&#39;s profile  320  are associated with the individual profile of Ben Bitdiddle  320  only. Some content items  335  within the Bitdiddle family social network group  330  are associated with the social network group of the Bitdiddle family  330  only. 
     Content items  345  within region  340  are associated with the individual profiles of both Alice Bitdiddle  310  and Ben Bitdiddle  320 . As region  340  includes information about both Alice Bitdiddle and Ben Bitdiddle, content items  345  in region  340  are interesting for the Bitdiddle family social network group  330 . Thus, content items  345  in region  340  might be automatically brought into the Bitdiddle family social network group  330 . However, it should be noted that either Alice Bitdiddle or Ben Bitdiddle may opt out of having their content items  345  automatically brought into the Bitdiddle family social network group  330 . The content presentation server  120  may ensure that any other user associated with a content item  345  approves the content item being added to the social network group  330 . If a user other than Alice Bitdiddle or Ben Bitdiddle is associated with one or more content item  365  items that are to be automatically brought into the Bitdiddle family social network group, the other user may also opt out of having the content items automatically brought into the Bitdiddle family social network group  330 . 
     Content items  365  in region  360  are associated with all of Alice Bitdiddle&#39;s profile  310 , Ben Bitdiddle&#39;s profile  320 , and the Bitdiddle family group  330 . Content items  355  in region  350  are associated with Alice&#39;s profile  310  and the Bitdiddle family profile  330 . Content items  375  in region  370  are associated with Ben&#39;s profile  320  and the Bitdiddle family profile  330 . Content items  385  in region  380  are associated with neither Alice&#39;s profile  310 , nor Ben&#39;s profile  320 , nor the Bitdiddle family profile  330 . 
       FIG. 4  illustrates an example of the content presentation server  120  of  FIG. 1  in more detail. 
     As shown, the content presentation server  120  includes a processor  402 , a network interface  404 , and a memory  406 . The processor  402  is configured to execute computer instructions that are stored in a computer-readable medium, such as the memory  406 . For example, the processor  402  may be a central processing unit (CPU). The network interface  404  is configured to allow the content presentation server  120  to transmit and receive data in the network. The network interface  404  may include one or more network interface cards (NICs). The memory  406  stores data and instructions. As illustrated, the memory  406  stores a “social network group-content item relation module”  408 , a “content item combination module”  410 , a “permission verification module”  412 , a “display social network group module”  414 , a “generate social network group map module”  416 , and a map  418 . 
     The “social network group-content item relation module”  408  is configured to determine that a new content item that, initially, is not associated with a social network group could be associated with the social network group and to associate the new content item with the social network group. The social network group-content item relation module  408  may operate by receiving the new content item not associated with the social network group and determining that the new content item is related to the social network group. The new content item may be related to the social network group if the new content item is associated with at least two subject members of the social network group or at least a certain proportion of the subject members of the social network group. The new content item may be associated with one or more subject members, for example, the one or more subject members may have the content item on their individual profiles or the one or more subject members may comment, prefer or otherwise indicate an interest in the new content item, or the one or more subject members may be named in the new content item. 
     The “content item combination module”  410  is configured to combine two or more related content items, e.g., the two content items  222  and  224 , into a single content item, e.g., content item  220 . The content item combination module  410  may determine, for example, that a first content item is related to a second content item, and that the combination of the first content item and the second content item is related to asocial network group. Content items may be related to one another if the posters of the content items, or others associated with the content items, are both subject member of the social network group and the content items are associated with the same geographic point of interest and are proximate in time, thereby indicating that the some of the subject members may have interacted with the same geographic point of interest at the same time. For example, if two subject members of the social network group indicate that they are at the same restaurant at approximately the same time, the content item combination module  410  may conclude that the two members were at the restaurant together and create a new content item indicating this information. The new content item created by the content item combination module  410  may include an indication of each content item from which the new content item was generated. When the content item combination module  410  combines a first content item and a second content item into a new content item, the set of users who have permission to view the new content item may include the intersection of the set of users who have permission to view the first content item and the set of users who have permission to view the second content item. A user of the social networking service may opt out from having new content items generated based on the content items associated with the user. 
     The “permission verification module”  412  is configured to determine if a requesting user who requests to view a content item has permission to view the content item. The permission verification module  412  may ensure that a set of users who have permission to view a content item that is added to a social network group by either the social network group-content item relation module  408  or the content item combination module  410  includes the viewing members of the social network group. A user posting a new content item may set the permission for other users to view the new content item. The user may allow all users to view the new content item or only members of certain social network groups or social circles to view the new content item. 
     The “display social network group module”  414  is configured to cause information associated with a social network group  208  to be provided or transmitted for display. The information may be provided or transmitted in response to a request from a requester to view the information associated with the social network group. Alternatively, the information may be stored in a feed associated with the social network group, which my be accessible to a viewing member of the social network group. The display social network group module  414  may provide or transmit map  418  for display on the client computing device  130  of the requestor. In responding to a request from the requestor to view the information associated with social network group  208 , the display social network group module  414  may determine that the requestor is a viewing member of the social network group and, if so, store or transmit for display a representation of a map  418  including one or more of the content items  214 ,  216  or  218  associated with the social network group and an indication of the social network group, such as a name, a title, or an image associated with the social network group. If at least one of the content items  214 ,  216  or  218  lacks a geographic location or has a geographic location that is not within the displayed geographic region of the representation of the map  418  on the client computing device  130 , then the at least one of the content items  214 ,  216  or  218  may be displayed externally to the map  418 . The display social network group module  414  may further determine that the requestor has permission to view the content items  214 ,  216  or  218  that are provided for display on or off the map  418 . 
     The “generate social network group map module”  416  is configured to generate the map  418  associated with the social network group. The generate social network group map module  416  may operate by associating the content items provided to the generate social network group map module with geographic locations and generating a map  418  including some of the geographic locations. The map  418  may include representations of the content items associated with the social network group positioned on the map  418  proximate to the geographic locations on the map. 
     In one example, the map  418  may be a map of the State of California, and the content items associated with the social network group may include a photograph taken in Los Angeles, a video taken in San Francisco, a video chat room with an ongoing chat session, and a geographic check-in of a subject member of the social network group in London, England. The map  418  may include a thumbnail of photograph content item taken in Los Angeles overlaying Los Angeles and a thumbnail of a scene in the video content item taken in San Francisco overlaying San Francisco. The video chat room content item may be presented externally to the map, as the video chat room content item lacks a geographic location. The geographic check-in content item in London cannot be represented within the displayed geographic region of the map  418 . Thus, the geographic check-in content item may be presented externally to the map  418 . 
       FIG. 5  illustrates a web browser window  500  presenting a webpage configured to implement displaying content items related to a social network group on a map. 
     As shown, the web browser window  500  includes a title bar  502 , a close button  504 , a “social network group title”  506 , a “social network group photograph”  508 , a representation of a map  510 , a representation of a content item  518  outside the map  510 , and an interaction button  520  for the content item  518  outside the map  510 . 
     The title bar  502  is typically located a the top of the web browser window  500  and may include the title of the webpage, for example the name of the social networking service, “First Social Network.” 
     The close button  504  is configured to close the web browser window when clicked. 
     The “social network group title”  506  may include the title of the social network group. As illustrated, the title “John Smith” may indicate that the individual profile of John Smith is being presented. 
     The “social network group photograph”  508  includes a primary photograph associated with the social network group. The photograph  508  may be an image that includes one or more members of the social network group. As shown, the photograph  508  is an image of John Smith. 
     The representation of the map  510  may include one or more content items  512 ,  514 , and  516 , that may be associated with a geographic location in the displayed geographic region of the map. As shown, the map  510  includes a peninsula. Content item  512 , “photo album beach,” is associated with a geographic location near the northern end of the peninsula. The geographic location of content item  512  may be the location where the photographs in “photo album beach” were taken. Content item  514  is a “review of First Café.” The geographic location of content item  514  may correspond to the street address of First Café, which may be determined from the content item  514 , from other data stored in database  110  or from an external database. Content item  516  indicates John&#39;s present location. The content presentation server  120  may determine John&#39;s location by receiving the location from a mobile device, for example client computing device  130 , that belongs to John. However, John or any other user of the social networking service may opt out of having his mobile device transmit its location to the content presentation server  120  or of having his current location displayed on the webpage. 
     Content item  518  is a chat room that may not correspond to any geographic location. As a result, content item  518  is presented in the webpage outside the map  510 . Interaction button  520  allows a viewer of the webpage to interact with content item  518 , for example, by joining a chat session. In one implementation, (not illustrated) content items having a geographic location outside the displayed geographic region on the map  518  may also be presented on the webpage outside the map. Either a full content item or a representation of the content item, such as a thumbnail or a blurb, may be presented. 
     In one implementation, the web browser window  500  may further include an input for receiving a time range (not illustrated). The input for receiving a time range may include a text box for the user to enter a start date and an end date or one or more scroll bars with which a user may select a start time and an end time by operating a cursor. One scroll bar may be provided for selecting the start time and another scroll bar may be provided for selecting the end time. Alternatively, a single scroll bar with an adjustable length or width scroll thumb may be used for selecting both the start time and the end time. One end of the scroll thumb may represent the start time and another end of the scroll thumb may represent the end time. 
     One or more of the content items  512 ,  514  or  516  on the map may be associated with a time. For example, image and video content items may be associated with times that the image or video content items were taken and article content items may be associated with the publication times of the article content items. Alternatively, content items may be associated with times that the content items were posted to the social networking service. Content items that are associated with a time within the time range selected by the user may be displayed on the map, while content items that are associated with a time outside the time range selected by the user may not be displayed or may be displayed externally to the map. 
       FIG. 6  illustrates a process  600  by which a content item related to a social network group may be displayed on a map  418 . 
     The process  600  begins at step  610 , where the content presentation server  120  receives a new content item  220  that is not associated with a social network group. The information associated with the social network group may include a set of subject members and a set of viewing members. The new content item may be one or more of a photograph, a video, an article, a text, audio or video chat room, a status update, a geographic check-in or a calendar event. The social network group may include a single individual profile, a combination of two or more individual profiles, a social circle or a symmetric social network group, for example, if the content item is associated with at least 20% of the subject members of the social network group. 
     According to step  620 , the content presentation server  120  determines that the new content item is related to the social network group. The new content item may be related to the social network group if the new content item is associated with at least two subject members of the social network group or if the new content item is associated with at least a certain proportion or percentage of the subject members of the social network group. 
     According to step  630 , the content presentation server  120  stores the new content item in association with the social network group. In one example, the content presentation server  120  may determine that all viewing members of the social network group have permission to view the new content item and store the new content item in association with the social network group only if all of the viewing members have permission to view the new content item. 
     The content presentation server  120  may then receive a request to display the social network group from a client computing device  130  belonging to a requestor. The content presentation server may determine that the requestor is a viewing member  210  of the social network group and that the requestor has permission to view the new content item  220 . 
     According to step  640 , the content presentation server  120  associates the new content item with a geographic location. The new content item may include a geographic location. For example, a photograph, video or check-in may be coupled with a geographic code that indicates the geographic location. Alternatively, the content presentation server  120  may derive the geographic location based on a point of interest name included in the new content item. For example, the new content item may be a review of a business, and the content presentation server  120  may associate the new content item with the address of the business, which may be determined through the database  110  or another database. A poster of the new content item may opt out of having the new content item associated with any data or addresses from outside the new content item. 
     According to step  650 , the content presentation server  120  generates a map including the geographic location. The map may include a representation of the new content item, which may be positioned on the map proximate to the geographic location on the map. For example, the representation of the new content item may overlay the map at the geographic location. 
     According to step  660 , the content presentation server  120  provides for display a representation of the map and an indication of the social network group, such as a name, a title, or an image associated with the social network group. The content presentation server  120  may then transmit the representation of the map and the indication of the social network group to the client computing device for display. After step  660 , the process  600  ends. 
       FIG. 7  illustrates a process by which a displayed geographic region of a map displaying content items related to a social network group may be modified. 
     The process  700  begins at step  710 , where the content presentation server  120  determines a displayed geographic region of the representation of the map based on the geographic location of the new content item. The geographic region of the representation of the map  418  may be based on all of the content items to be displayed. The geographic region may include the locations all of the content items, at least a certain proportion or percentage of the content items, or at least one of the content items. 
     According to step  720 , the content presentation server  120  receives a request to modify the displayed geographic region of the representation of the map. The request to modify the displayed geographic region may include, for example, a request to pan, zoom in or zoom out the map. 
     According to step  730 , the content presentation server  120 , in response to the request to modify the displayed geographic region, provides for display a representation of the map including anew displayed geographic region according to the request. For example, the content presentation server  120  may cause the map to be panned, zoomed in or zoomed out according to the request. The data provided for display may be transmitted to the client computing device  130 . 
     According to step  740 , the content presentation server  120  determines that the geographic location of the new content item is external to the new displayed geographic region, as modified by the request. For example, a zoom in request to the center of the map may cause the geographic location of the new content item to be external to the new displayed geographic region if the geographic location is located close to an edge of the map. 
     According to step  750 , the content presentation server  120  causes the representation of the new content item to be removed from the map. As a result, the representation of the new content item on the screen of the client computing device  130  may appear externally to the map. 
     According to step  760 , the content presentation server  120  causes the representation of the new content item to be displayed externally to the map. 
     Many of the above-described features and applications are implemented as software processes that are specified as a set of instructions recorded on a computer readable storage medium (also referred to as computer readable medium). When these instructions are executed by one or more processing unit(s) (e.g., one or more processors, cores of processors, or other processing units), they cause the processing unit(s) to perform the actions indicated in the instructions. Examples of computer readable media include, but are not limited to, CD-ROMs, flash drives, RAM chips, hard drives. EPROMs, etc. The computer readable media does not include carrier waves and electronic signals passing wirelessly or over wired connections. 
     In this specification, the term “software” is meant to include firmware residing in read-only memory or applications stored in magnetic storage, which can be read into memory for processing by a processor. Also, in some implementations, multiple software technologies can be implemented as sub-parts of a larger program while remaining distinct software technologies. In some implementations, multiple software technologies can also be implemented as separate programs. Finally, any combination of separate programs that together implement a software technology described here is within the scope of the subject technology. In some implementations, the software programs, when installed to operate on one or more electronic systems, define one or more specific machine implementations that execute and perform the operations of the software programs. 
     A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it can be deployed in any form, including as a stand alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network. 
       FIG. 8  conceptually illustrates an electronic system  800  with which some implementations of the subject technology are implemented. For example, one or more of the database  110 , the content presentation server  120 , or the client computing device  130  may be implemented using the arrangement of the electronic system  800 . The electronic system  800  can be a computer, phone, PDA, or any other sort of electronic device. Such an electronic system includes various types of computer readable media and interfaces for various other types of computer readable media. Electronic system  800  includes a bus  805 , processing unit(s)  810 , a system memory  815 , a read-only memory  820 , a permanent storage device  825 , an input device interface  830 , an output device interface  835 , and a network interface  840 . 
     The bus  805  collectively represents all system, peripheral, and chipset buses that communicatively connect the numerous internal devices of the electronic system  800 . For instance, the bus  805  communicatively connects the processing unit(s)  810  with the read-only memory  820 , the system memory  815 , and the permanent storage device  825 . 
     From these various memory units, the processing unit(s)  810  retrieves instructions to execute and data to process in order to execute the processes of the subject technology. The processing unit(s) can be a single processor or a multi-core processor in different implementations. 
     The read-only-memory (ROM)  820  stores static data and instructions that are needed by the processing unit(s)  810  and other modules of the electronic system. The permanent storage device  825 , on the other hand, is a read-and-write memory device. This device is anon-volatile memory unit that stores instructions and data even when the electronic system  800  is off. Some implementations of the subject technology use a mass-storage device such as a magnetic or optical disk and its corresponding disk drive as the permanent storage device  825 . 
     Other implementations use a removable storage device (such as a floppy disk, flash drive, and its corresponding disk drive) as the permanent storage device  825 . Like the permanent storage device  825 , the system memory  815  is a read-and-write memory device. However, unlike storage device  825 , the system memory  815  is a volatile read-and-write memory, such a random access memory. The system memory  815  stores some of the instructions and data that the processor needs at runtime. In some implementations, the processes of the subject technology are stored in the system memory  815 , the permanent storage device  825 , and/or the read-only memory  820 . For example, the various memory units include instructions for displaying content items related to asocial network group on a map, in accordance with some implementations. From these various memory units, the processing unit(s)  810  retrieves instructions to execute and data to process in order to execute the processes of some implementations. 
     The bus  805  also connects to the input and output device interfaces  830  and  835 . The input device interface  830  enables the user to communicate information and select commands to the electronic system. Input devices used with input device interface  830  include, for example, alphanumeric keyboards and pointing devices (also called “cursor control devices”). Output device interfaces  835  enables, for example, the display of images generated by the electronic system  800 . Output devices used with output device interface  835  include, for example, printers and display devices, such as cathode ray tubes (CRT) or liquid crystal displays (LCD). Some implementations include devices such as a touchscreen that functions as both input and output devices. 
     Finally, as shown in  FIG. 8 , bus  805  also couples electronic system  800  to a network (not shown) through a network interface  840 . In this manner, the electronic system  800  can be a part of a network of computers (such as a local area network (“LAN”), a wide area network (“WAN”), or an Intranet, or a network of networks, such as the Internet. Any or all components of electronic system  800  can be used in conjunction with the subject technology. 
     These functions described above can be implemented in digital electronic circuitry, in computer software, firmware or hardware. The techniques can be implemented using one or more computer program products. Programmable processors and computers can be included in or packaged as mobile devices. The processes and logic flows can be performed by one or more programmable processors and by one or more programmable logic circuitry. General and special purpose computing devices and storage devices can be interconnected through communication networks. 
     Some implementations include electronic components, such as microprocessors, storage and memory that store computer program instructions in a machine-readable or computer-readable medium (alternatively referred to as computer-readable storage media, machine-readable media, or machine-readable storage media). Some examples of such computer-readable media include RAM, ROM, read-only compact discs (CD-ROM), recordable compact discs (CD-R), rewritable compact discs (CD-RW), read-only digital versatile discs (e.g., DVD-ROM, dual-layer DVD-ROM), a variety of recordable/rewritable DVDs (e.g., DVD-RAM, DVD-RW, DVD+RW, etc.), flash memory (e.g., SD cards, mini-SD cards, micro-SD cards, etc.), magnetic and/or solid state hard drives, read-only and recordable Blu-Ray® discs, ultra density optical discs, any other optical or magnetic media, and floppy disks. The computer-readable media can store a computer program that is executable by at least one processing unit and includes sets of instructions for performing various operations. Examples of computer programs or computer code include machine code, such as is produced by a compiler, and files including higher-level code that are executed by a computer, an electronic component, or a microprocessor using an interpreter. 
     While the above discussion primarily refers to microprocessor or multi-core processors that execute software, some implementations are performed by one or more integrated circuits, such as application specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs). In some implementations, such integrated circuits execute instructions that are stored on the circuit itself. 
     As used in this specification and any claims of this application, the terms “computer”, “server”, “processor”, and “memory” all refer to electronic or other technological devices. These terms exclude people or groups of people. For the purposes of the specification, the terms display or displaying means displaying on an electronic device. As used in this specification and any claims of this application, the terms “computer readable medium” and “computer readable media” are entirely restricted to tangible, physical objects that store information in a form that is readable by a computer. These terms exclude any wireless signals, wired download signals, and any other ephemeral signals. 
     To provide for interaction with a user, implementations of the subject matter described in this specification can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user&#39;s client device in response to requests received from the web browser. 
     The subject matter described in this specification can be implemented in a computing system that includes a back end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front end component, e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the subject matter described in this specification, or any combination of one or more such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks). 
     The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In some aspects of the disclosed subject matter, a server transmits data (e.g., an HTML page) to a client device (e.g., for purposes of displaying data to and receiving user input from a user interacting with the client device). Data generated at the client device e.g., a result of the user interaction) can be received from the client device at the server. 
     It is understood that any specific order or hierarchy of steps in the processes disclosed is an illustration of exemplary approaches. Based upon design preferences, it is understood that the specific order or hierarchy of steps in the processes may be rearranged, or that all illustrated steps be performed. Some of the steps may be performed simultaneously. For example, in certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components illustrated above should not be understood as requiring such separation, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.
