La Grammaire en Chaîne Revisitée ou le Système de L'araignée

A syntactic analyzer based on a string grammar is presented. The handling of idioms — a difficult problem for parsers — is more satisfactory than what has been accomplished until now. It appears that it is necessary to distinguish the lexical and syntactic phases of the analysis. Moreover, using a sentence graph structure makes this system really powerfull. There are four main points to this paper: — the architecture of the parser: — the identification of idioms based upon a new categorization of those forms; — the use of a sentence graph structure; — the description of the string grammar analyzer.
