Abstract
A natural language processing system for processing an original text by applying grammar rules, includes a grammar rule control table for holding information on applicability of the grammar rules to the original text, the information containing dictionary information associated with words appearing in the original text, and means for determining application or non-applicability application of each grammar rule based on the applicability information. The application conditions for applying each grammar rule are collectively evaluated or examined based on the information on the applicability of the grammar rules contained in the dictionary information and information on the text type, sentence type and domain of subject of the original text, and the result is stored in the grammar rule control table.
