NewsGator Delivers Recommended RSS Articles via Collaborative Filtering

DENVER, CO--(Marketwire - May 22, 2008) - NewsGator Technologies, Inc. announced today that it has integrated Uprizer Labs' SenseArray collaborative filtering capabilities into its NewsGator Online RSS Reader to provide recommended stories to users. The unique combination of relevance data gathered from NewsGator's users and SenseArray's powerful filtering delivers an innovative recommendation system giving users great stories from feeds they've never seen.

The recommended stories feature works by sending to SenseArray the relevance data collected when users click links, tag, save or forward articles. Users can also give direct feedback on the recommended articles with simple "thumbs up" and "thumbs down" controls. All users get a set of recommended recent stories chosen from the seven million new daily articles NewsGator retrieves. Users can also display recommendations within Top News, Entertainment, Sports, Fun Stuff, Science and Technology categories.

"Added to NewsGator Online, SenseArray will recommend stories to a person based on their normal interactions with their favorite NewsGator RSS Reader," said Ian Clarke, CEO of Uprizer Labs. "In early tests, the system is proving to be extremely accurate in its ability to predict users' tastes and interests."

"Collaborative filtering has been extremely successful in helping users find products on services like Amazon.com and Netflix," said Brian Kellner, vice president of products for NewsGator. "NewsGator is using our huge stream of relevance actions in a truly innovative way with the SenseArray collaborative filter to provide the same kind of recommendation capabilities with RSS articles."
