Top (20) Semantic Search Tools 2010

Semantic search tools seek to improve search accuracy by understanding the intent of searchers and the contextual meaning of terms as they occur in desirable web documents. Instead of Google’s PageRank to predict relevancy, semantic search tools use the science of meaning in language to produce relevant results. The goal is to deliver the information queried by a user rather than have a user sort through a list of loosely related keyword results. Some authors regard semantic search tools as a set of techniques to retrieve knowledge from richly structured data sources like ontologies. The following twenty (20)  technologies enable the articulation of domain knowledge and to specify users’ information needs (take a look):

  1. Hi, thats a pretty good list. I found a couple I had not heard of before. You should also include PureDiscovery in Texas. They recently released a semantic search application with LexisNexis that is powered by the largest semantic intelligence layer (they claim) in the world. I read that the intelligence was built from over 200,000,000 docs.

  4. This is a great list. You must have researched this area extensively. The one major omission is TipTop http://FeelTipTop.com which is arguably more impressive than some of the ones you picked.
