Abstract: Two different user spaces can be mapped to each other based on one or more categories of information that are common to both. The mapping is based on hash values generated by applying the same hash function to the same information of the categories of information that identifies users in each user space.

Abstract: A technique for determining the effectiveness of an offer includes analyzing views, clicks, acceptances and satisfactions of the offer. Transaction data is retrieved to determine whether criteria of the offer has been satisfied. As a result, a total cost per transaction may be determined for an advertisement campaign that incorporates the offer. Further, detailed queries may be issued to identify areas in which the offer needs improvement.

Abstract: A technique for tracking conversion of an online offer includes tracking online and/or offline transactions. A customer accepts an offer provided by a merchant and submits his or her account information so that he or she may receive a reward for satisfying criteria associated with the offer. Transactions of the merchant are then monitored at the payment processor level to determine whether the customer satisfies the purchase criteria. Therefore, online and offline conversion can both be tracked. Further, the merchant is able to determine the overall effectiveness of advertising campaigns by analyzing the number of offers that are both accepted and satisfied.

Abstract: A system is described that receives first user identifiers from a first user space and a first set of hash values generated from a hash function applied to first information that identify users associated with the set of first user identifiers. The system determines a hash value included in both of the first set of hash values and a second set of hash values that are generated from the hash function being applied to second information that identify users associated with second user identifiers from a second user space. The system generates a mapping between the first user identifiers and the second user identifiers that each correspond to the same hash value. The system determines targeted information directed to the first user identifiers and based on the mapping, outputs the targeted information to user devices associated with the second user identifiers.

Abstract: In particular embodiments, a computing system may receive a search query from a first user of an online social network, identify one or more second users of the online social network that match the search query, where each identified second user may have a visibility setting specifying which other users of the online social network can view information from the online social network associated with the second user, and send to the first user information associated with each second user having a relationship within the online social network to the first user such that the visibility setting of the second user specifies that the first user can view the information associated with the second user.

Abstract: Particular embodiments access a search query submitted by a first user of a social-networking system; identify one or more web pages in response to the search query; for each of the one or more web pages, determine a value indicating a number of user clicks associated with the web page by one or more second users of the social-networking system who are connected to the first user within the social-networking system; and send a set of hyperlinks for the one or more web pages, wherein hyperlinks for web pages where the value is greater than zero are visually emphasized over other hyperlinks.

Abstract: Particular embodiments receive, at a first computing device associated with a social-networking system and from a second computing device associated with a third-party system, a query comprising a first identifier corresponding to a user of the third-party system, wherein the first identifier is computed by applying a hash algorithm to a user credential associated with the user of the third-party system; determine, by the first computing device, whether the user of the third-party system matches any member of the social-networking system; and if the second identifier corresponding to a member of the social-networking system matches the first identifier, then send, by the first computing device to the second computing device, social-network information of the member of the social-networking system in response to the query.

Abstract: In particular embodiments, a computing system may receive a search query from a first user of an online social network, identify one or more second users of the online social network that match the search query, where each identified second user may have a visibility setting specifying which other users of the online social network can view information from the online social network associated with the second user, and send to the first user information associated with each second user having a relationship within the online social network to the first user such that the visibility setting of the second user specifies that the first user can view the information associated with the second user.

Abstract: Particular embodiments access a query submitted by a first user; retrieve information concerning one or more second users; retrieve a degree of separation between the first user and each second user within a social-networking system; and for each second user, if the degree of separation between the first user and the second user is less than or equal to a threshold degree of separation, then send the information concerning the second user to the first user in response to the query.

Abstract: Particular embodiments receive an indication from a first user that the first user desires to play a game; retrieve, from a social-networking system, one or more second users who are connected to the first user within a threshold degree of separation within the social-networking system; and invite each second user to play the game with the first user.

Abstract: Particular embodiments access a query from a first user, the query comprising a first user attribute; identify a plurality of candidate users sharing the same first user attribute; retrieve one or more members of a social-networking system who are connected to the first user within a threshold degree of separation; compare each candidate user with each member who is connected to the first user within the threshold degree of separation; and if a candidate user matches a member who is connected to the first user within the threshold degree of separation, then identify the matching candidate user as a match result to the query.
