A system and method for managing user activity context includes monitoring a user's actions on an electronic device; analyzing a resource accessed by the user; identifying an activity being performed by the user based on the analysis of the resource; and generating an activity context graph for the identified activity, wherein the activity context graph includes information regarding the resource. The activity context graph may be updated with additional resources accessed by the user if the additional resources are associated with the identified activity. The activity context graph may be provided to another user and may be updated to reflect the other user's profile, settings, or other information.
