Abstract : SRI International is engaged in a long-term research effort under DARPA sponsorship to develop techniques for facilitating the acquisition of knowledge of computers. The ultimate goal is to build KLAUS(Knowledge-Learning and -Using System), a computer program that could acquire a model of a domain of interest by being instructed in English. The model could then be used for domain-related tasks. Systems based on the KLAUS concept would be useful for a variety of applications, including sophisticated interfaces to computer software, advanced database systems, and intelligent computer assistants. This report covers work done on the KLAUS project during the period July 1981 to January 1982. Section 2 describes DIALOGIC, the natural-language processing system used in MICROKLAUS, which is our current preliminary implementation of the KLAUS concept. The dialogic system translates English sentences into representation of their literal meaning in the context of an utterance. Section 3 describes a new scheme for syntax-directed translation of natural language into logical form. That scheme, comprising the basis of an English translation system called PATR, was used to specify a semantically interesting fragment of English that included such constructs as tense, aspect, modals, and various lexically controlled verb complement structures.
