This paper presents a supervised method for resolving metonymies. We enhance a commonly used feature set with fea- tures extracted based on collocation in- formation from corpora, generalized us- ing lexical and encyclopedic knowledge to determine the preferred sense of the potentially metonymic word using meth- ods from unsupervised word sense disam- biguation. The methodology developed addresses one issue related to metonymy resolution – the influence of local context. The method developed is applied to the metonymy resolution task from SemEval 2007. The results obtained, higher for the countries subtask, on a par for the compa- nies subtask – compared to participating systems – confirm that lexical, encyclo- pedic and collocation information can be successfully combined for metony...
