Abstract: Within a social network, users may submit various types of messages, such as personal messages to other users and status messages to be shared with all associated users. While these messages often relate to highly personal information such as opinions and personal emotions, such messages may also comprise one or more facts about a particular topic, such as a report of a weather condition in a particular location at a particular time. These facts may be identified in various messages, and may be stored in a fact store, such that when a user submits a query specifying a topic may receive from the fact store one or more facts that are responsive to the topic of the query. Additionally, user interfaces may be devised and provided to users submitting such messages, e.g., in order to reduce ambiguity and improve the reliable extraction of facts from messages.
