Abstract: A system and method for targeted event detection and notification based on combinations of time, location and context. A database stores information about users of the system including profile information, and information about real world events such as date, time, and event information. Events are tagged with information that allows searching. A suggestion engine matches particular events to particular users. Events are private (individually), private to groups, and public. A third party such as merchant or advertiser can generate and publish events to users who possess specified profiles. User information is de-identified to address privacy concerns. Users are provided with notifications of events or offers that meet their interest profiles and may accept such events or offers to their calendars, reminder list, timeline or otherwise.
