Described embodiments enable the presentation to a user of news articles or other content that is of likely interest to a user and that is temporally and/or geographically relevant to the user's location or region of interest. A news delivery system includes an ingest module that assigns topics, locations and dates to available content, a profile engine that determines profile topics and geographic locations that a particular user finds relevant, and a news delivery module that selects content for the user based on the operation of the ingest module and the profile engine and the desired timeframe. In one embodiment, the profile engine performs decay processing to remove stale topics and locations from a user's profile. In related aspects, the profile engine maintains multiple profiles for the user. |
