1. A computer system method for matching an utterance of a user to a template comprising the steps of:

  • (a) receiving by a processor the utterance from an input device, wherein the utterance includes at least one word;

    (b) accessing a set of template hierarchies from a database, wherein the set includes at least one template;

    (c) comparing by the processor the at least one word of the utterance to the at least one term of a template hierarchy in the set of template hierarchies;

    (d) determining by the processor whether the at least one word of the utterance matches the at least one term of the template hierarchy;

    (e) calculating by the processor a score based on the match between the at least one word of the utterance and the at least one term of the template hierarchy;

    (f) repeating steps (c)-(e) until there are no more words of the utterance for said comparing step;

    (g) populating the at least one template with at least one data element corresponding to the at least one term of the template hierarchy to obtain a populated template;

    (h) computing a total score based on the match between all words of the utterance to the populated template;

    (i) selecting by the processor the at least one template with the highest total score;

    (j) recording the populated template; and

    (k) communicating the populated template to the user.
