Abstract : This report summarizes research done on the KLAUS project from July 1981 to July 1983. In July 1980 we began work on the second KLAUS system, called MICROKLAUS, and on the technological base needed to support it. Our initial experience with MICROKLAUS led us to redesign the parsing and translation system to provide for a declarative semantics that is easier both to extend and to maintain, and to augment the deduction system along a number of dimensions. These development efforts proceeded independently, with the natural-language-processing and deduction components being only recently rejoined. We have also made significant progress on several fundamental problems of natural-language semantics and on specifying the planning and reasoning capabilities needed for generating adequate responses. Our systems have been moved from the DEC 2060 to the Symbolics 3600 LISP machine. We expect these new components to provide the core of a new KLAUS system with significantly more powerful capabilities for communication in natural language. The base they provide also leaves us in a position to attack several fundamental research problems holding back the development of advanced KLAUS systems and other types of advanced systems that require high-quality natural-language capabilities.
