I’ve been playing around with Powerset, a new Semantic Search Engine, which uses natural language search technology that is based on patents licensed exclusively from Palo Alto Research Center (formerly Xerox) and its own proprietary indexing.
Instead of being limited to keywords, Powerset allows you to enter keywords, phrases, or questions. Instead of just showing you a list of blue links, Powerset gives you more accurate search results, often answering questions directly, and aggregates information from across multiple articles.
I have to confess I am very impressed with it – I used it for a few hours late last night to help find some references for a blog piece I’m writing and loved the way it seemed to understand the concepts I was asking about rather than giving me matches based on keywords. Currently it only searches Wikipedia but does also provide results from Freebase as well. I really find the MiniViewer useful, it allows you to view a short result snippet presented on the results screen within the other original context it was extracted from, this also makes the search results feel interactive.
Here’s the demonstration video that explains how Powerset is different using some cool examples:
I’m really interesting in seeing where Powerset goes next …
