Semantic search from Cognition

Today's reference site is a search engine. In fact, it's three search engines from Cognition, a natural language processing technology company in Culver City, California. These search engines employ linguistic computation techniques to deliver search results with superior relevance, since the engine is able to determine the context of query.

"Cognition's technology employs a mix of linguistics and mathematical algorithms which has, in effect, taught the computer the meanings of virtually all the words and frequent phrases within the common English language. Semantic Natural Language Processing is superior to common pattern matching that is found in most search engines and text-interaction tools because it focuses on the understanding of word and phrase meanings within context. No other commercially available natural language processing technology comes close to Cognition in its breadth and depth of understanding the English language."

Cognition is not aiming to be a competitor to Google and other www search engines; rather, their goal is to apply semantic indexing to large datasets to deliver better results.

Cognition has made specialized search engines for three major websites:

Cognition's semantic search of Wikipedia
Cognition's semantic search of Medline
Cognition's semantic search of case law available from Public.Resource.org
