     BACKGROUND 
       [0003]    This invention relates generally to social-networking websites and other systems in which users can form connections with other users. 
         [0004]    Social networks, or social utilities that track and enable connections between users (including people, businesses, and other entities), have become prevalent in recent years. In particular, social-networking websites allow users to communicate information more efficiently. 
         [0005]    For example, a user may post contact information, background information, job information, hobbies, or other user-specific data to a location associated with the user on a social-networking website. Other users can then review the posted data by browsing user profiles or searching for profiles including specific data. Social-networking websites also allow users to associate themselves with other users, thus creating a web of connections among the users of social-networking website. These connections among the users can be leveraged by the website to offer more relevant information to each user in view of the users&#39; own stated interests in their connections. 
         [0006]    A system, such as a website, that allows users to interact with the system typically stores a record for each users of the system. These records may comprise information provided by the user as well as information gathered by the system related to activities or actions of the user on the system. For example, a system may require a user to enter information such as contact information, gender, preferences, interests, and the like in an initial interaction with the system, which is stored in the user&#39;s record. A user&#39;s activities on the system, such as frequency of access of particular information on the system, also provide information that can be stored in the user&#39;s record. The system may then use information provided by the user and information gathered about the user, to customize interactions of the system with the user. For example, a website selling books may keep track of a users previous purchases and provide the user with information on related books during subsequent interactions with the system. Information in a user&#39;s profile may also be used by the system to target sponsored stories that are of interest to the user. Using information collected from and about users results in a system that is more efficient and beneficial for both the user and the system. 
         [0007]    Users interacting with the social network may post stories or status updates to a live activity stream, such as a “news feed.” A news feed is a data format typically used for providing users with frequently updated content. A social-networking system may provide various news feeds to its users, where each news feed includes content relating to a specific subject matter or topic, or other users. Various pieces of content may be aggregated into a single news feed. In some implementations, a social-networking system may provide a news feed that includes selected entries corresponding to activities of a user&#39;s first-degree contacts or pages or topics that a user has indicated an interest for. Individual users of the social-networking system may subscribe to specific news feeds of their interest. A group of related actions may be presented together to a user of the social-networking system in the same news feed. For example, a news feed concerning the event organized through the social-networking system may include information about the event, such as its time, location, and attendees, and photos taken at the event, which have been uploaded to the social-networking system. 
         [0008]    Generally, news feeds are customized for each member; only the status updates and stories posted by their connections are displayed. In this manner, members of the social network may quickly access their direct connections&#39; status updates, story postings, and other interactions with the social network in a single stream, obviating the need to individually check their connections&#39; profile pages. 
         [0009]    However, given the vast number of contacts the average member of a social network has, and the prodigious amounts of status updates posted by users, it is possible that stories of interest to the user are lost in the unending stream of their news feed. Furthermore, sponsors may wish to pay for permanence of a particular story in members&#39; news feeds; this functionality is unavailable in typical social-networking systems. 
         [0010]    Typically sponsors pay for a static advertisement to be displayed to a member of the social network. In particular embodiments, advertisements may be displayed to a member&#39;s home page on the social network, mobile devices, third-party web pages and applications, television and other video streams, or any other particular display accessed by a member of the social network. Despite data-mining techniques that match users based on their preferences, activities, or other data stored in their social-networking profile to the most relevant sponsored or promoted stories, no system currently exists for promoting a story from a user&#39;s news feed to the sponsored-stories space of a social-network home page. Sponsored or promoted stories generated from actual stories in users&#39; news feeds are more likely to be viewed by users, because they generally involve interactions or suggestions by their connected friends or fan pages that they are connected or subscribed to.

       [0022]    The figures depict various embodiments of the present invention for purposes of illustration only. One skilled in the art will readily recognize from the following discussion that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles of the invention described herein. 
       DETAILED DESCRIPTION 
       [0023]    Particular embodiments relate to a social-networking environment including a social-networking system and related systems that integrate individual stories, status updates, and user interactions with an advertising system. A social-networking system offers its users the ability to communicate and interact with other users of the social-networking system. Users join the social-networking system and then add connections to a number of other users to whom they desire to be connected. Once they are members of the social network, the users may interact with the social network itself, by posting stories and status messages on their own page, other users, by commenting, posting stories, etc. on other users&#39; pages, or with non-user entities, such as fan pages that they subscribe to, online deals they redeem or subscribe to, or locations that they check in to. 
         [0024]    Implementations of this disclosure extend these concepts by allowing sponsors or specific users to export by promoting specific news feed stories to sponsored-story space on users&#39; social-networking pages, thereby increasing the permanence and viewing frequency of these stories. In one example, a user may want to promote one of his news stories so that more of his connected friends can see the story in a more frequent and permanent view. For example, a sponsor who publishes an application, such as a social-networking game, may wish for status updates generated with its application to have permanence on the application user&#39;s friends&#39; homepages. In another example, a sponsor associated with a page on the social network, may want to promote news stories when a user connects to the page on the social network or to an object associated with the sponsor off network. In another example, the proprietor of a store may wish to promote news stories to a user&#39;s friends when that user “checks-in”, or indicates that he physically visited, the store. In another example, the proprietor of a store may wish to promote news stories to a user&#39;s friends when that user subscribes, purchase, or redeems a deal or coupon associated with the sponsor. Other embodiments are readily envisioned by the disclosure and are described in detail below. 
         [0025]      FIG. 1  illustrates an example social-networking website  100 . The system environment comprises one or more client devices  110 , one or more third-party websites  140 , a social-networking website  100 , and a network  120 . In alternative configurations, different or additional modules can be included in the system. 
         [0026]    Client devices  110  comprise one or more computing devices that can receive member input and can transmit and receive data via network  120 . For example, client devices  110  may be desktop computers, laptop computers, smart phones, personal digital assistants (PDAs), or any other device including computing functionality and data communication capabilities. Client devices  120  are configured to communicate via network  120 , which may comprise any combination of local area or wide area networks, using both wired and wireless communication systems. Third party website  140  and action terminal  150  are coupled to network  120  for communicating messages to social-networking website  100  about the members&#39; actions off website  100 . 
         [0027]    Social-networking website  100  comprises a computing system that allows members to communicate or otherwise interact with each other and access content as described herein. Social-networking website  100  stores member profiles that describe the members of a social network, including biographic, demographic, and other types of descriptive information, such as work experience, educational history, hobbies or preferences, location, and the like. Website  100  further stores data describing one or more relationships between different members. The relationship information may indicate members who have similar or common work experience, group memberships, hobbies, or educational history. Additionally, social-network host site  120  includes member-defined relationships between different members, allowing members to specify their relationships with other members. For example, these member-defined relationships allow members to generate relationships with other members that parallel the members&#39; real-life relationships, such as friends, co-workers, partners, and so forth. Members may select from predefined types of relationships, or define their own relationship types as needed. 
         [0028]      FIG. 2  illustrates example hardware components of social-networking website  100 . Social-networking website  100  includes a web server  250 , an action logger  260 , an action log  160 , a news feed generator  270 , an ad server  280 , a database of ad requests  175 , a member profile store  205 , a group store  210 , an event store  215 , an application data store  220 , a transaction store  225 , and a content store  230 . In other embodiments, social-networking website  100  may include additional, fewer, or different modules for various applications. 
         [0029]    Web server  250  links social-networking website  100  via network  220  to one or more client devices  110 , as well as to one or more third party websites  140 . Web server  250  may include a mail server or other messaging functionality for receiving and routing messages between social-networking website  100  and client devices  110  or third party websites  140 . The messages can be instant messages, queued messages (e.g. e-mail), text and SMS messages, or any other suitable messaging technique. 
         [0030]    Action logger  260  is capable of receiving communications from the web server  250  about member actions on or off social-networking website  100 . News feed generator  270  generates communications for each member about information that may be relevant to the member. These communications may take the form of stories; with each story being an information message comprising one or a few lines of information about an action in action log  160  that is relevant to the particular member. The stories are presented to a member via one or more pages of the social-networking website  100 , for example in each member&#39;s home page or news feed page. 
         [0031]    Ad server  280  executes one or more ad-selection algorithms. Ad server  280  is communicatively coupled to the database of ad requests  175  and to action log  160  for this purpose. 
         [0032]      FIG. 3  illustrates example interaction between sponsored-story application  301  and an activity stream  302  in particular embodiments. In particular embodiments, sponsored-story application  301  may be software residing within the sponsored-story system  304  or part of stream-sponsored-story-specification database  305 . In particular embodiments, sponsored-story application  301  may be software executed by any number of servers in the social-networking system, either in conjunction or in isolation. In particular embodiments, sponsored-story application  301  may reside on its own dedicated hardware. Activity stream  302  comprises the aggregate stream of status updates and news stories for all users of a social network. Activity stream  302  under normal operation passes to news feed engine  303 , which parses the individual stories in activity stream  302  and determines which users&#39; (generally the friends of the user who generated the story) pages to display each story on. In particular embodiments, both activity stream  302  and news feed engine  303  are applications residing in server  307 . In particular embodiments, activity stream  302  or news feed engine  303  are applications distributed across one or more computing servers. This disclosure contemplates any suitable implementation of activity stream  302  and news feed engine  303 . 
         [0033]    A sponsor uses sponsor GUI  306  to specify the type of stories it wants promoted to the sponsored-story section of users&#39; pages. Examples of Sponsor GUI  306  are depicted in  FIGS. 6A and 6B . Sponsor GUI  306  provides a method for the sponsor to create story filters to locate specific types of news feed stories for promoting to the sponsored-story space of a user&#39;s home page. Once the sponsor sets up its preferences for the types of stories it wishes to promote to the sponsored-story portion, the sponsor specifications are stored into stream sponsored-story specification database  305 . 
         [0034]      FIG. 4  illustrates an example method for the sponsored-story system. In step  401 , sponsored-story application  301  constantly monitors activity stream  302 , searching for matches to any of the sponsored-story specifications in stream-sponsored-story-specification database  305 . In step  402 , the sponsored-story system compares each story in the activity stream  302  to all stream-sponsored-story specifications in stream-sponsored-story-specification database  305 . If there is a match, the procedure continues to step  403 , if not, it loops back to  401 . 
         [0035]    In step  403 , upon finding a match, sponsored-story application  301  pulls the matching entry out of activity stream  302 , and formats the entry into a predetermined visual specification. In particular embodiments, the visual specification is dictated by the social-networking system to mimic a regular news feed story. In other embodiments, special identifiers may be added by the social-networking system to indicate that the story is a sponsored story. In other embodiments, the visual specifications are entered by the sponsor through the Sponsor GUI  306  at the time of stream story specification. In such an embodiment, the visual specification is stored along with the story specification in the stream-sponsored-story-specification database  305 . In particular embodiments, the sponsor is given limited discretion as to the visual specifications for the promoted stream story, subject to predetermined constraints imposed by the social-networking system. 
         [0036]    In step  404 , after the story is formatted pursuant to the visual specification or by the social-networking system to visually comport with a news feed story, the sponsored story is passed to sponsored-story system  304 . 
         [0037]    In step  405 , after a social story is formatted into a sponsored story, it is priced and directed toward users in a similar manner as a social ad. In particular embodiments, the user may also add a weight to the story to alter its direction toward users. For example, certain stories may decay quickly, such as check-ins, and are not displayed to other users beyond a predetermined threshold time period from the story generation. In other embodiments, user-specified temporal factors, such as deadlines, may increase the weight of the sponsored story so that it is promoted over other sponsored stories lacking time sensitivity. 
         [0038]    In particular embodiments, ad targeting is based upon an affinity score calculated by social-networking website  100 . A member may have affinities for other members, types of actions, types of objects, and content. Accordingly, a calculated affinity score may be based on a weighted function that takes into account the set of affinities for the particular member for each type of data field that is in a candidate story. The website may obtain a member&#39;s affinities based on the member&#39;s express interests (whether provided directly or indirectly, for example, through communications with other members) or impliedly based on the member&#39;s actions (e.g., a member&#39;s checking of another member&#39;s page indicates an interest in that other member, or clicking on particular types of links may indicate an interest in similar links). An affinity, as measured for example by an affinity score, need not be an actual subjective interest or lack of interest that a member has for something (i.e., the member likes punk rock music, and dislikes vegetarian restaurants), but rather it may merely be a correlation between something in the candidate story and some information stored in connection with that member, whether is an action taken by the member, a communication involving the member, a characteristic, feature or expressed interest in the member&#39;s profile. 
         [0039]      FIG. 5  illustrates example components of a sponsored-story system in a social-networking system. In this sponsored-story model, a number of sponsors  502  bid for the placement of sponsored stories on a social-networking website  100 . A social-networking website operator  501  receives these bids, for example, through a web interface accessible to sponsors  502 . Accompanying each bid is a description of the sponsored story that sponsor  502  would like to publish to for display to a particular set of members of the social network. This disclosure contemplates a variety of methods of publishing the sponsored story. In particular embodiments, the sponsored story is published on a social network member&#39;s home page on the social network. In particular embodiments, the sponsored story may be displayed on a predetermined area of a mobile device. In particular embodiments, the sponsored story may be published through notifications in the social network. In particular embodiments, the sponsored story may be published through e-mail, instant messaging, or other messaging applications. In particular embodiments, the sponsored story may be displayed on a third-party website integrated with the social network. The web interface may thus allow sponsor  502  to specify all of the relevant information for a sponsored-story request, including the bid amount for the sponsored story. 
         [0040]    The bid amount specified in the sponsored-story request may indicate an amount of money that sponsor  502  will pay for each time a member presented with the sponsored story clicks on it. In particular embodiments, the sponsor may be a non-profit or charity where the bid amount is given at little or no cost. Alternatively, the bid amount may specify an amount that sponsor  502  will pay the website operator  501  each time the sponsored story is displayed to a member or a certain number of members or each time the sponsored story is clicked on by a member or a certain number of members. In another embodiment, the sponsor may pay a set amount per month or period of time and the social-networking website will determine the bid amount or how and when to display the sponsored stories. In addition, the sponsored-story request may allow sponsor  502  to specify targeting criteria. This targeting criteria may be a filter to apply to fields of a member&#39;s member profile or other object, or it may include free form text such as wall posts, comments, and messages. In particular embodiments, to optimize the targeting and selection of sponsored stories for users of a social network, social information gathered on and off the social network about a user is leveraged to infer interests about users of the social network. A social network may maintain a social graph that identifies the mapping of connections among the users, including entities such as businesses, applications, groups, etc, of a social network, and the social network may also maintain profiles that contain full or partial information about each of the users in the social network. Targeting may be based one or more factors such as member demographics (age, gender, location, birth date, age, education level, employers, employment type, work history and experience, hobbies, and or preferences. These factors may draw from explicit member statements such as listing it on their profile, connections to other members or entities, or through user-entered text on and off the social networking site. In another embodiment, these factors may be implicitly or inferred by the social network. 
         [0041]    One or more sponsored stories available to the social network may contain targeting criteria for determining whether the sponsored story should be targeted to a particular user. While the social network may have sufficient information about some of its users to apply the targeting criteria, the social network may not have sufficient information about other users to apply the targeting criteria. Rather than missing out on the opportunity to target sponsored stories to this latter group of users, embodiments use the information for other users to whom a particular user is connected when the social network does not have sufficient information to apply the targeting criteria to the user. This may be thought of as “inferential” targeting because a user&#39;s likely interest in a particular ad is inferred based on whether that user&#39;s connections (e.g., friends in the social network) are good candidates for the sponsored story based on its targeting criteria. 
         [0042]      FIG. 6A  depicts an example sponsor GUI  601 . Sponsor GUI  601  includes a drop down window  610  that allows a user of sponsor GUI  601  to select any previously saved stream-sponsored-story specification  602   a - 602   e.  User controls  603 ,  604 , and  605  give the user the option to save, deactivate/activate, or delete an existing stream-sponsored-story specification. User control  606  provides the user with the option to create a new stream-sponsored-story specification. The process of creating a new stream-sponsored-story specification is described in detail below. 
         [0043]    Upon selecting user control  606 , the user is presented with another set of drop down commands  607 . Drop down menu  607  lists all the entities with which a user is associated in the social network. Examples of such an entity include but are not limited to, pages that the user has created to interact with fans of the page, such as for a musician or TV show, applications associated with the user, such as social-networking games, deals or coupons associated with the user, and physical locations associated with the user that members of the social network may “check in” to, to indicate that they or others were physically at the location. 
         [0044]    After the user has selected the entity associated with the user to be included in the stream-sponsored-story specification, the user selects, using drop down menu  608 , the types of interactions members of the social network have with the entity on and off the social network that the user would like to promote to the sponsored-story space. User interactions include, but are not limited to tagging, sharing, “liking”, commenting on media or mentioning a user in a status update or comment, fringing someone, RSVPing or inviting a user to an event or game, and the like. Other user interactions include but are not limited to “check-ins” and other location-based social interactions, sharing a link from a third-party website, “liking” a post or page from a third-party site, buying, redeeming, or subscribing to deals and other promotions, and interacting with an application on or off the social network. Any time a user makes a connection or performs a social action on the social network, a new story is generated in activity stream  302  that may ultimately be promoted. 
         [0045]    Depending on the type of entity selected in drop down menu  607 , the interactions available in menu  608  available to the user vary. For example, if the user selects a page, such as for a band or musician, from menu  607 , the interactions in  608  may include: when a member “likes” the page, when a member posts a link on page, when the page owner (generally, but not necessarily, the user of the sponsor GUI itself) posts a link on the page, or when a member shares a link to an external website that is related to the page. As another example, if the user of the sponsor GUI selects a place, such as a store location, from drop down menu  607 , the GUI may show, in drop down menu  608 : when a member of the social network “checks in” to the place, when a member of the social network gives a review of the place greater than a predetermined threshold, or when a member of the social network “likes” the place. 
         [0046]    As described above, actions by users performed off of a social-networking website (e.g., actions on third party websites or in the real world) may be used to generate sponsored stories on the social-networking website. Conversely, in particular embodiments, a social-networking website can collect its users&#39; actions and then present sponsored stories or other information concerning actions taken by its users on third party websites. In this way, the techniques for promoting actions using this information can be extended beyond a social-networking website itself. 
         [0047]    Alternative embodiments are contemplated by the disclosure that may be contemplated by ones of ordinary skill in the art. In particular embodiments, the user may specify geographic or temporal criteria used by sponsored-story system  304  in determining which users to display the sponsored story to. For example, a user may desire to promote a promotion that expires in three days, and may specify to only promote stories for the next three days. In other embodiments, the user may specify to promote stories only for users located with a specific geographic location. In particular embodiments, user may specify a threshold of people taking the same action. For example, a user may want to display friend check-ins to members of the social network only if two or more friends of the user check-in to a given location substantially simultaneously. In such an embodiment, sponsored-story application  301  may search for multiple check-ins to a given location by friends of a specific users within a predetermined time period. If such stories are found, sponsored-story application  301  may aggregate the plurality of stories into a single sponsored story. After the user is satisfied with the specifications of the stream sponsored story that has just been created, the user may utilize controls  603  and  604  to save and activate the sponsored story, respectively. 
         [0048]      FIG. 6B  illustrates an example simplified sponsor GUI  306 . The sponsor may use controls  610  and  620  to select where to display the sponsored story. For example, in  620 , the user may select to display the sponsored story on targeted members&#39; walls. Using controls  640 , the sponsor may select what kind of story sponsored-story application  301  should search for in activity stream  302 . In this example, the sponsor may select from a page post story, page “like” story, or a place check-in story. Finally, the sponsor GUI  306  may provide a preview  650  of the sponsored story. 
         [0049]    In  FIG. 7 , a user&#39;s news feed  701 , recommendation space  702 , sponsored-story space  703 , notifications  704 , and questions  705  are depicted. In particular embodiments, elements  701 - 705  are displayed on a social-networking user&#39;s home screen. In particular embodiments, element  701  is displayed on a user&#39;s home screen, and one or more of elements  702 - 705  are displayed at all times. This disclosure contemplates any arrangement of elements  701 - 705  and any degree of persistence. In particular embodiments, elements  702 - 705  are displayed on other user&#39;s pages. In particular embodiments, these other users may be the user&#39;s friend. In other embodiments, these other users may be otherwise associated with the user. In particular embodiments, the display of elements to other users  702 - 705  is determined by sponsored-story system  304 . Sponsored-story system  304  accesses a database of user privacy preferences when determining which users to display the sponsored story to. For example, if a user has previously specified that he or she does not wish to see sponsored stories from a particular company, sponsored-story system  304  will not display stories promoted by that particular company. In particular embodiments, sponsored-story system  304  accesses the visibility and privacy settings of the user that generated the news feed story to be promoted, and uses the settings in determining which users to display the promoted story to. For example, a user may have multiple friend lists, and members belonging to one or more different lists may be prevented from viewing specific stories, types of stories, or the user&#39;s news feed altogether. sponsored-story system  304  respects these settings so that only friends of the user who are granted access to view the news feed story to be promoted are displayed the promoted stream sponsored story. This disclosure contemplates various methods of determining which users to display element  703  to as envisioned by those of ordinary skill in the art. News feed  701  includes news feed stories  701   a - 701   d.  These stories are generated specifically for a user based upon the activities the user&#39;s friends or other entities the user is associated with. News feed story  701   b  is an example of a news feed story that has been selected for promoting to sponsor space  703 . When sponsored-story application  301  detects a match in activity stream  302  to a sponsor&#39;s stream-sponsored-story specification from stream-sponsored-story-specification database  303 , sponsored story  703  is formatted to resemble a news feed story and sent to sponsored-story system  304 . In this particular example, the stream story relates to a story when four friends of a user “liked” the entity “Toys ‘R’ Us.” Formatted sponsored story  703  is promoted to the user or another set of users by sponsored-story system  304 . 
         [0050]      FIGS. 7A-E  illustrate example sponsored stories  703 . Each sponsored story  703  includes a social context  38 . In particular embodiments, social context  38  comprises the user who performed the social action, a descriptor of the action, and a comment entered by the user who performed the social action. Sponsored stories  703  may also include an attribution  39 , corresponding to the entity selected by the sponsor in sponsor GUI  306 . In particular embodiments, the attribution is the node with which the user interacted or connected with to generate the stream story. For example, in  FIG. 7B , the user interacted with the entity “Starbucks” by checking-in to a Starbucks location. In  FIG. 7C , user interacted with the entity or node “CNN Heroes” by “liking” the entity. Sponsored stories  703  may also include a bling indicator  43 , which provides a visual indication as to how many members of the social-networking site have commented or liked the sponsored story. Emu like interface  6  allows users to quickly interact with the node/entity by “liking” it. In particular embodiments, sponsored story  703  may include an action link  42 , which allows a user, when selecting the link, to quickly perform a predetermined action, such as, in  FIG. 7A , donating to a particular cause.  FIG. 7D  depicts an example where an share link  24  to share a story published by an entity or node, in this case “CNN Heroes,” is provided. Upon clicking share link  24 , the user is taken to an interface depicted in  FIG. 7E , which allows the user to publish the sponsored story back to his or her own news feed. Action link  42  in  FIG. 7E  posts the sponsored story to the user&#39;s own wall along with any comments the user optionally chooses to append to the story. The embodiments depicted in  FIGS. 7A-7E  are merely examples and are in no way limiting; this disclosure contemplates any number of formatting and actions for sponsored stories.
