A collaboration system provides a collaboration interface for display to interacting users. The collaboration system analyzes messages among a group of users to determine an intent of the group to collaborate. When an intent is assigned to a set of messages, the collaboration system generates collaboration interfaces to prompt each of the users to select their preferred values for attributes of the collaboration, such as a meeting location, time, and date. The user selections are recorded in a collaboration data object which is monitored for matching selections. When multiple users have selection the same values for attributes of the collaboration the collaboration data object is locked from further changes and the collaboration system executes tasks to resolve the intent such as booking tickets, making reservations, and providing confirmation messages to the collaborating users.
