What is “Linguistic Search?
Linguistic Search is a linguistically-based technique that interprets the meaning of queries, and extracts concepts from them. Then it searches for those concepts in a pre-indexed document base. For example, if you ask “Did they adopt the bill?,” it will search on the concept “adopt” which can also be expressed as “approve”. Thus it will find documents that mention “approve a bill” or “approval of bill”, or any of the very many ways that concept can be expressed. This paraphrasing capability enables Cognition to exhaustively find nearly all documents relevant to a query. Notice that concept searching distinguishes between “adopt” meaning “approve”, and “adopt” meaning “bring into one’s family”. Thus it avoids irrelevant retrievals of documents using “adopt” in that other meaning. Another capability is reasoning in the Cognition taxonomy. If you ask about “vehicle”, Cognition retrieves documents about all kinds of vehicles from carts to jet airplanes and space ships.
