Abstract: An online system maintains characteristics for its users and may access characteristics of users maintained by a third party system. The online system may select content for a user of the third party system based on characteristics maintained by the third party system. If the third party system does not maintain a characteristic for its users, the generates a model predicting the characteristic for third party system users based on a set of online system users identified based on characteristics of third party system users. The online system clusters third party system users based on the predicted characteristic for other third party system users connected to the third party system user. Using verified characteristics for third party system users from a trusted third party system, the online system determines an accuracy of the predicted characteristic for third party system users in a cluster.

Abstract: A social networking system maintains characteristics with its users, with various characteristics, such as age, specified by the users (i.e., “asserted characteristics”). The social networking system selects content for a user based at least in part on the characteristics associated with the user. To account for potential inaccuracies in an asserted age of a user, the social networking system clusters users based on ages of other users connected to users. The online system receives verified ages for users in a cluster from a trusted third party system that maintains more accurate characteristics for users than the social networking system. By comparing the asserted ages for users in the cluster to the verified ages for users in the cluster, the social networking system determines an accuracy of the asserted ages for users in the cluster. The accuracy may be used when selecting content for the users.

Abstract translation: 社交网络系统保持与其用户的特征，具有由用户指定的诸如年龄的各种特征（即“断言特征”）。 所述社交网络系统至少部分地基于与用户相关联的特征为用户选择内容。 为了说明用户的断言年龄的潜在不准确性，社交网络系统根据与用户连接的其他用户的年龄对用户进行聚类。 在线系统从可信第三方系统接收集群中的用户的已验证年龄，对于用户而言，社交网络系统保持更准确的特性。 通过将群集中用户的断言年龄与群集中用户的已验证年龄进行比较，社交网络系统确定群集中用户的断言年龄的准确性。 当为用户选择内容时可以使用精度。
