Research in Natural Language Understanding

Abstract

This report contains an annual summary of BBN's ARPA-sponsored natural language understanding project and two Technical Notes: 'KLONE's Progress,' by R.J. Brachman, and 'Generalizations of ATN Grammars,' by W.A. Woods. The Annual summary includes a list of publications of the project and an overview of the first year's work. The first Technical Note focuses on the progress in the development of the KLONE knowledge representation system, an implementation of Brachman's Structured Inheritance Networks. The second describes some generalizations of the notion of ATN grammar, including Cascaded ATN's(a sequence of nondeterministic ATN transducers with each successive ATN taking its input from the output of the previous), Generalized Transition Networks (a generalization of the notion of ATN to handle arbitrary structured input rather than only linear strings), and an interpretation of KLONE networks as a kind of ATN with inheritance.
