Abstract:

This report summarizes the research of BBNs ARPA-sponsored Knowledge Representation for Natural Language Understanding project during its fourth year. In it we report on advances, both in theory and implementation, in the areas of knowledge representation, natural language understanding, and abstract parallel machines. In particular, we report on theoretical advances in the knowledge representation system KL-ONE, extensions to the KL-ONE system, and new uses of KL-ONE in the domain of knowledge about graphic displays. We report on a design for a new prototype natural language understanding system, on issues in cascaded architectures for interaction among the components of a language system, and on a module for Lexical acquisition. In addition, we examine three topics in discourse a new model of speaker meaning, which extends our previous work on speakers intentions, an investigation of reference planning and identification, and a theory of one-anaphora interpretation. Our discussion of abstract parallel machines reports on a class of algorithms that approximate Quillians 49 ideas on the function of human memory. Author
