摘要：An information server directs users of the information server to desired sourcesof information where the desired sources of information are determined, at least in part,based on user input. The information server includes a query input processor, a questionprocessor and an answer processor. The query input processor is used for accepting aninitial user query. The question processor processes the initial user query to identify a setof possible well-formed questions selected from the question database, where a well-formed question is a question in the database that is coupled to at least one answerreference. The answer reference is typically either an answer or a pointer to a possiblelocation of an answer. In a specific embodiment, the information server is coupled to theInternet so that users can pose questions using a Web browser from any Internet-connected device. In some systems, the question processor includes a tokenizer fortokenizing the initial user query into a list of words, a parser for generating a syntacticstructure from the list of words, a normalizer for reducing the syntactic structure to acanonical syntactic structure, and a matcher for matching the canonical syntacticstructure against a semantic network to obtain a weighted list of well-formed questionsrepresentative of possible semantic meanings for the initial user query.
