Cognition Technologies has launched CognitionSearch, a linguistic search engine supporting synonymy, morphology and ontology, and at the same time, tapping one of the world's largest computational dictionaries known to man. With this approach, Cognition has become the advanced search engine for the LexisNexis Concordance service, a software service that is currently used today on 65,000+ desktops.



The combination of formal linguistic algorithms with semantic representations is at the core of Cognition's patented technology and combine to create a fast semantics via computational parsing. What makes this works is the use of 4.000.000 semantic representations, 350,000 word stems, 376,000 word senses or concepts, 17,000 ambiguous word definitions, 100,000 phrases, 7,000 nodes for the ontology or tree structure of the taxonomy, and 50,000 thesaural concept groups. Cognition's clients using the software are provided with tools to add their own specialized terminology. In the case of very large term expansions, Cognition will also supply them with a consulting service to augment the CognitionSearch service.

The Advanced Search mode will seem familiar to professional searchers with a lot of experience dealing with database services. The Advanced Search mode offers five basic search approaches: plain English search, linguistic Boolean search, quoted search, pattern search, and fuzzy search.
