Abstract
An enhanced natural language information retrieval technique tokenizes an incoming query, comparing the tokenized representation against a collection of query templates. Query templates include a first portion having one or more query patterns representative of a query and in a form suitable for matching the tokenized representation of an incoming query. Query templates also include one or more information retrieval commands that are designed to return information relevant to those query patterns in its first portion. The enhanced natural language information retrieval technique selects those query templates that are determined to be most relevant to the incoming query (via its tokenized representation) and initiates one or more information retrieval commands associated with the selected query templates.
