| #3 choice | Powerset is a natural language search engine. It's fair to say that Powerset has had a great 2008, having been acquired by Microsoft in July this year. Powerset's goal is to change the way people interact with technology by enabling computers to understand our language. While this is a difficult challenge, we believe that now is the right time to begin the journey. Powerset is first applying its natural language processing to search, aiming to improve the way we find information by unlocking the meaning encoded in ordinary human language. | 1 people | 0 people | 0 0 0 0 0 | Free | http://www.powerset.com/ | Web |
