The process will identify the absence period and that is being participated by a user and obtains extracted information relating to the user that was previously gathered from a variety of sources including past user interactions and a user profile. This information is further analyzed and prioritized according to user interest priority determined by the extracted information. This information is categorized into a first set of domains. Information provided during the absence of the user will also be captured and categorized into a second set of domain categories. An intersection between the first and second set of domain categories will be found and prioritized by user interest. This will be presented to the user upon user's return.
