1. A query recognition system operating on a server coupled to the Internet comprising:

  • a natural language routine configured to generate a first linguistic analysis of words contained in a text query, including an identification of any word phrases present in said text query using one or both of grammars or dictionaries appropriate for a context of said text query;

    a query formulation routine adapted to convert said words and said word phrases into a structured, combined query suitable for locating matching question/answer pairs for said text query;

    wherein said first linguistic analysis is used to identify a candidate set of potential matching question/answer pairs for said text query; and

    an answer identification routine configured for comparing said first linguistic analysis with one or more second linguistic analyses of words contained in said matching question/answer pairs so as to determine a best answer to said text query from the matching question/answer pairs, the best answer being determined from the question/answer pair that best matches the text query;

    wherein the best answer is communicated over the Internet in response to said text query in real time.
