Abstract : IRUS-II is the understanding subsystem of the Janus natural language interface. IRUS-II is a 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. Natural language interfaces, User interfaces, Knowledge bases.
