Abstract: This paper gives an overall account of a prototype natural language question answering system, called Chat-80. Chat-80 has been designed to be both efficient and easily adaptable to a variety of applications. The system is implemented entirely in Prolog, a programming language based on logic. With the aid of a logic-based grammar formalism called extraposition grammars, Chat-80 translates English questions into the Prolog subset of logic. The resulting logical expression is then transformed by... (Update)

...to a movie database would involve a completely different lexicon. In 1982, CHAT80 was implemented in order to address this portability issue[6]. Unfortunately, it proved difficult to port. ASK tried to address similar issues by allowing users to add words to the lexicon,...
...1975 version of PROLOG. The research reported here has motivated further work on logic programmed NL processors for data bases (e.g. [2,22,32], and on the need of extending the original MG formalism [24] On the other hand, the data base component of this system, together with...
