The MetaCarta NewsMap service

"The MetaCarta NewsMap service is a hosted service that lets publishers dynamically display maps that show the places mentioned in their news stories. The NewsMap service processes the text of stories using our proprietary geoparsing and geotagging technology to extract the geographic places mentioned in them, and resolves them to their respective latitude and longitude coordinates. The places are then represented as an overlay of markers on virtually any digital map such as those from Google, Yahoo!, and Microsoft"
