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.
