Combining Collocations, Lexical and Encyclopedic Knowledge for Metonymy Resolution

چکیده
This paper presents a supervised method for resolving metonymies. We enhance a commonly used feature set with features extracted based on collocation information from corpora, generalized using lexical and encyclopedic knowledge to determine the preferred sense of the potentially metonymic word using methods from unsupervised word sense disambiguation. 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 companies subtask – compared to participating systems – confirm that lexical, encyclopedic and collocation information can be successfully combined for metonymy resolution.

متن کاملLogical Metonymy Resolution in a Words-as-Cues Framework: Evidence From Self-Paced Reading and Probe Recognition
Logical metonymy resolution (begin a book → begin reading a book or begin writing a book) has traditionally been explained either through complex lexical entries (qualia structures) or through the integration of the implicit event via post-lexical access to world knowledge. We propose that recent work within the words-as-cues paradigm can provide a more dynamic model of logical metonymy, accoun...
