USYD: WSD and Lexical Substitution using the Web1T corpus
This paper describes the University of Sydney’s WSD and Lexical Substitution systems for SemEval-2007. These systems are principally based on evaluating the substitutability of potential synonyms in the context of the target word. Substitutability is measured using Pointwise Mutual Information as obtained from the Web1T corpus. The WSD systems are supervised, while the Lexical Substitution syst...
متن کاملThe English lexical substitution task
Since the inception of the SENSEVAL series there has been a great deal of debate in the word sense disambiguation (WSD) community on what the right sense distinctions are for evaluation, with the consensus of opinion being that the distinctions should be relevant to the intended application. A solution to the above issue is lexical substitution, i.e. the replacement of a target word in context ...
متن کاملCOLEPL and COLSLM: An Unsupervised WSD Approach to Multilingual Lexical Substitution, Tasks 2 and 3 SemEval 2010
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...
متن کاملUnsupervised Cross-Lingual Lexical Substitution
Cross-Lingual Lexical Substitution (CLLS) is the task that aims at providing for a target word in context, several alternative substitute words in another language. The proposed sets of translations may come from external resources or be extracted from textual data. In this paper, we apply for the first time an unsupervised cross-lingual WSD method to this task. The method exploits the results ...
متن کاملInvited talk: Evaluating Automatic Approaches for Word Meaning Discovery and Disambiguation using Lexical Substitution
There has been a surge of interest in Computational Linguistics in word sense disambiguation (WSD). A major catalyst has been the SENSEVAL evaluation exercises which have provided standard datasets for the field over the past decade. Whilst researchers believe that WSD will ultimately prove useful for applications which need some degree of semantic interpretation, the jury is still out on this ...
