Clustering for categorial grammar induction (Inférence grammaticale guidée par clustering) [in French]

Clustering for categorial grammar induction In this article, we describe the way we use hierarchical clustering to learn an AB grammar from partial derivation trees. We describe AB grammars and the derivation trees we use as input for the clustering, then the way we extract information from Treebanks for the clustering. The unification algorithm, based on the information extracted from our cluster, will be explained and the results discussed. MOTS-CLÉS : grammaires catégorielles, clustering hiérarchique, inférence grammaticale.
