Abstract: A system, method, and computer program product dynamically prioritizes electronic messages. An electronic message having one or more properties is received. These message properties can include, a particular sender or body text. Information describing past activity of a recipient user of the electronic message is accessed. A priority is determined for the electronic message, where the determining is based at least in part on a comparison of a property of the electronic message with the accessed information. The priority determination may include detecting the presence of a request in the electronic message, determining the social weight of the sender of the electronic message, determining the temporal urgency of the electronic message, or determining the relevance of the electronic message, for example. An indication of the priority of the message is presented to the recipient user.

Abstract: A user interface for an electronic calendar represents different locations or different users or different user calendars in different portions of the display. Calendar entries can be associated with one or more locations, one or more users, and with one or more user calendars. The different locations may reside in different time zones and a timeline for each time zone is displayed. The position of the calendar entry provides a visual identifier of the timeline with which the event is associated. Travel time to and from events in the calendar are calculated for calendared events and shown adjacent to the beginning and end of the event. A user's future location at a point in time is inferred from patterns in the user's locations and by analyzing the user's calendared events and correspondence in order to calculate travel time to calendared events.
