1. A method of optimizing the performance of speech recognition and language understanding in a natural language processing system, comprising:

  • compiling a first set of full names based on usage of the names in the dialog;

    compiling a second set of full names based on presence in a pre-defined knowledge base;

    deriving partial names for one or more of the names of the first set of full names and the second set of full names;

    combining the partial names and the first and second set of full names to generate a name model; and

    assigning weight values to each of the names of the name model, wherein the relative weights depend on the usage of the names in the dialog and the presence in the pre-defined usage list.
