Abstract : SRI International is engaged in a long-term effort under DARPA sponsorship to conduct basic research on artificial intelligence problems central to the construction of computer systems that can participate in extended dialogues in natural language with their users. A central thrust to our research is that the system be able to acquire new concepts, facts, and vocabulary through dialogues with the users. It is equally important that the system not be limited to querying for individual facts-as it is the case, for example, with database query systems. Rather this research provides a base for constructing systems that can engage in extended interactions to determine what a user intends (including when this differs from what he literally requests), and that provide responses appropriate to a particular user and discourse situation. Among the core capabilities of these systems are those for reasoning about the knowledge, goals, and plans of other agents where these other agents may be users or other computer systems. This report covers work done on the KLAUS (Knowledge-Learning and-Using System) project during the period July 1982 to January 1983. This work consisted of developing two aspects of KLAUS: the natural-language-processing component and the deduction system component.
