Abstract: A social networking system determines common location information included in a set of posts between a set of users. Using the determined common location information, the social networking system generates a message interface for grouping a set of messages into a conversation thread. For example, the messages may be grouped into a conversation thread based on common location information in the messages and being associated with participants sharing a social relationship. When a group conversation is created, the social networking system presents a message interface containing the conversation thread to one or more participants of the thread. The social networking system adds the set of messages to the conversation thread based on social information about the social relationships among the participants of the conversation thread. The social networking system then presents the message interface for display to one or more of the participants.
