Research in Knowledge Representation for Natural Language Communication and Planning Assistance
Abstract
BBN's DARPA project in Knowledge Representation for Natural Language Communication and Planning Assistance has two primary objectives: 1) To perform research on aspects of the interaction between users who are making complex decisions and systems that are assisting them with their task. In particular, this research is focused on communication and the reasoning reasoning required for performing its underlying task of discourse processing, planning and plan recognition and communication repair. 2) Based on the research objectives to build tools for communication, plan recognition, and planning assistance and for the representation of knowledge and reasoning that underlie all of these processes. This final report summarizes BBN's research activities performed under this contract in the areas of knowledge representation and speech and natural language. In particular, the report discusses our work in the areas of knowledge representation, planning and discourse modelling. We describe a parallel truth maintenance system. We provide an extension to the sentential theory of propositional attitudes by adding a sentential semantics. The report also contains a description of our research in discourse modelling in the areas of planning and plan recognition. Keywords: artificial intelligence, intelligent interfaces, parallel processing.
