18. The system as claimed in claim 13 , wherein the expanding component for expanding the skeleton starts at a starting concept or relationship and moves out through neighboring concepts or relationship links in the source model, iterating outwards; and refines the expanded terms of concepts and relationships by augmenting scores.
13. A system for generating a natural language processing model for specific information domain, comprising: a processor configured for building a skeleton of a natural language lexicon for the specific information domain from a source model of the specific information domain and for using the skeleton of the natural language lexicon to form a dictionary, the skeleton comprising terms found in the source model, the source model comprising classification hierarchies for the terms, the terms including objects and attributes; a syntactic rule component for applying a set of syntactical rules defining concepts and relationships to the dictionary; and an expanding component, including an intersection component, for expanding the skeleton of the natural language lexicon based on reference documents and using the syntactic rule component to provide a natural language processing model, the natural language processing model utilized by a user in the specific information domain to analyze documents in the specific information domain, wherein expanding the skeleton comprises: clustering and scoring terms for concepts and relationships, and intersecting the syntactic rules and the clustered concepts and relationships.
