Abstract: At least one embodiment of this disclosure includes a method of inferring attribute labels for a user in a social networking system based on the user's social connections and user-specified attribute labels in the social networking system. The method can include: establishing variational equations based on attribute labels of nodes in an ego network in a social graph of a social networking system; determining likelihood scores for at least a portion of the attribute labels of neighboring nodes from a focal user node in the ego network based on user-specified attribute labels from the social networking system; and calculating probability distributions of possible attribute labels for the focal user node of the ego network based on the variational equations and the likelihood scores.

Abstract: The invention provides a display interface in a social networking system that enables the presentation of information related to a user in a timeline or map view. The system accesses information about a user of a social networking system, including both data about the user and social network activities related to the user. The system then selects one or more of these pieces of data and/or activities from a certain time period and gathers them into timeline units based on their relatedness and their relevance to users. These timeline units are ranked by relevance to the user, and are used to generate a timeline or map view for the user containing visual representations of the timeline units organized by location or time. The timeline or map view is then provided to other users of the social networking system that wish to view information about the user.

Abstract translation: 本发明提供一种社交网络系统中的显示界面，其能够在时间线或地图视图中呈现与用户相关的信息。 系统访问关于社交网络系统的用户的信息，包括关于用户的数据和与用户相关的社交网络活动。 然后，系统从特定时间段选择这些数据和/或活动中的一个或多个，并根据其相关性及其与用户的相关性将它们收集到时间轴单元中。 这些时间轴单元由与用户的相关性排序，并且用于为用户生成包含由位置或时间组织的时间轴单元的视觉表示的时间线或地图视图。 然后将时间线或地图视图提供给希望查看关于用户的信息的社交网络系统的其他用户。
