Metonimy resolution for named entities: an hybrid approach

Named Entity metonymy resolution is a challenging natural langage processing task, which has been recently subject to a growing interest. In this paper, we describe the method we have developed in order to solve Named entity metonymy in the framework of the SemEval 2007 competition. In order to perform Named Entity metonymy resolution on location names and company names, as required for this task, we developed a hybrid system based on the use of a robust parser that extracts deep syntactic relations combined with a non supervised distributional approach, also relying on the relations extracted by the parser. We describe this methodology as well as the results obtained at SemEval 2007 MOTS-CLÉS : entités nommées, métonymie, méthode hybride, analyse syntaxique robuste, approche distributionnelle.
