Abstract

LCS (Language Comprehension System) is a software package designed to improve man-machine communication with computer programs. Different simple structures and functions are available to build man-machine interfaces in natural language. A user may write a sentence in good English or in telegraphical style. The system used pattern matching techniques to detect misspelled words (or badly typed words) and to correct them. Several methods of analysis are available at any level (lexical, syntactic, semantic...). A special knowledge acquisition system is used to introduce new works by giving a description in natural language. A semantic network is extended to a representation close to a connexionist graph, for a better understanding of polysemic words and ambiguities. An application is currently used for a man-machine interface of an expert system in computer-aided education, for a better dialogue with the user during the explanation of reasoning phase. The object of this paper is to present the LCS system, especially at the lexical level, the knowledge representation and acquisition level, and the semantic level (for pronoun references and ambiguity).
