Abstract : IRUS-II is the understanding subsystem of the Janus natural language interface. IRUS-II is natural language understanding (NLU) shell. That is, it contains domain-independent algorithms, a large grammar of English, domain-independent semantic interpretation rules, and a domain-independent discourse component. In addition, several software aids are provided to customize the system to particular application domains. These software aids output the four knowledge bases necessary for IRUS-II to correctly interpret English utterances and generate appropriate code for simultaneous access to multiple application systems. This document describes the four knowledge bases and how to construct them. This is the third volume of a three volume final report. (kr)
