Abstract:
Users of a social networking system are provided with advertisements when accessing content associated with the social networking system. The content of such advertisement may be generated by other users of the social networking system. An advertiser may provide an advertising template containing an advertised message and fields wherein a user can input an endorsement. The social networking system generates an advertisement responsive to the advertisement content provided by the advertiser and the endorsement content provided by the endorsing user. The social networking user can provide the generated advertisements to viewing users who meet the advertisement's targeting criteria, and display criteria or subject to privacy settings provided by the endorsing user.
Abstract:
An online system displays a first set of content items to a user of a test group and displays a second set of content items to a user of a control group. The online system presents a poll to each user to evaluate the user's recall of the content item associated with the poll. The online system receives a poll response from each user, which is input, along with a set of features associated each user, into a prediction model. The prediction model enables the online system to determine a poll response prediction of a third user based on a set of features associated with the third user. The poll response prediction enables the online system to determine if it would be effective to present the content item to the third user.
