EJNews2
EJNews2 is an advanced news system that periodically crawls a database of Internet news sources, gathers story data, indexes and ranks the stories, and finally clusters stories with similar subject matter. The news is gathered from sites that present their news in an XML (RDF/RSS) format. Any site that presents its news items in a common RDF or RSS format can be added to the system for inclusion.
You can see EJNews2 in action by clicking the 'World news' link above.
