چکیده

In this paper we describe the English Lexical Substitution task for SemEval. In the task, annotators and systems find an alternative substitute word or phrase for a target word in context. The task involves both finding the synonyms and disambiguating the context. Participating systems are free to use any lexical resource. There is a subtask which requires identifying cases where the word is functioning as part of a multiword in the sentence and detecting what that multiword is.

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...

Evaluating Lexical Substitution: Analysis and New Measures

Lexical substitution is the task of finding a replacement for a target word in a sentence so as to preserve, as closely as possible, the meaning of the original sentence. It has been proposed that lexical substitution be used as a basis for assessing the performance of word sense disambiguation systems, an idea realised in the English Lexical Substitution Task of SemEval-2007. In this paper, we...

Tor, TorMd: Distributional Profiles of Concepts for Unsupervised Word Sense Disambiguation

Words in the context of a target word have long been used as features by supervised word-sense classifiers. Mohammad and Hirst (2006a) proposed a way to determine the strength of association between a sense or concept and co-occurring words—the distributional profile of a concept (DPC)—without the use of manually annotated data. We implemented an unsupervised naı̈ve Bayes word sense classifier u...
