- Weiwei Guo, Mona T. Diab. 2010. COLEPL and COLSLM: An Unsupervised WSD Approach to Multilingual Lexical Substitution, Tasks 2 and 3 SemEval 2010. Abstract: In this paper, we present a word sense disambiguation (WSD) based system for multilingual lexical substitution. Our method depends on having a WSD system for English and an automatic word alignment method. Crucially the approach relies on having parallel corpora. For Task 2 (Sinha et al., 2009) we apply a supervised WSD system to derive the English word senses. For Task 3 (Lefever & Hoste, 2009), we apply an unsupervised approach to the training and test data. Both of our systems that participated in Task 2 achieve a decent ranking among the participating systems. For Task 3 we achieve the highest ranking on several of the language pairs: French, German and Italian.
