1. A method for interpreting natural language input using a computer system comprising the steps of:

  • parsing said natural language input;

    disambiguating meanings and structure of said natural language input;

    generating a discourse representation, said discourse representation identifying said structure for said natural language input, meanings of words and relationships between components of said structure;

    resolving references in said natural language input;

    determining relationships that exist in said natural language input;

    consulting, within each of the above steps, a naive semantic lexicon to determine the plausibility of interpretative decisions made within each of the above steps, said naive semantic lexicon having at least one entry that identifies at least one sense of a word, said entry including a reference to an ontological classification network, syntactic information, and a plurality of semantic properties.
