Powerset has launched a new semantic search engine, which indexes and searches Wikipedia and Freebase. Powerset’s semantic technology is a hybrid of patents licensed from PARC (formerly Xerox PARC) and Powerset’s proprietary research; and unlike traditional search technologies from Google, Yahoo and Teoma; which look for words, Powerset matches the meaning of the users’ query to the meaning of sentences.

Natural language search attempts to serve more relevant results for user queries which go beyond the basic keyword model, serving results with higher precision and better recall, due to the searcher actually understanding the matching of results to the query.

Powerset’s natural language search engine gives its users the ability to search over 2.5 million Wikipedia articles. Yes, this is a lot of fanfare for a search technology which searches Wikipedia, or gives Wikipedia a new dimension of discovery.
