Categorial Dependency Grammars: from Theory to Large Scale Grammars
Résumé
Categorial Dependency Grammars (CDG) generate unlimited projective and non-projective dependency structures, are completely lexicalized and analyzed in polynomial time. We present an extension of the CDG, also analyzed in polynomial time and dedicated for large scale dependency grammars. We define for the extended CDG a specific method of ''Structural Bootstrapping'' consisting in incremental construction of extended CDG from representative samples of dependency structures. We also outline a wide coverage dependency grammar of French developed using this method.
