Word sense discrimination in information retrieval: A spectral clustering-based approach
Word sense ambiguity has been identified as a cause of poor precision in information retrieval (IR) systems. Word sense disambiguation and discrimination methods have been defined to help systems choose which documents should be retrieved in relation to an ambiguous query. However, the only approaches that show a genuine benefit for word sense discrimination or disambiguation in IR are generall...
متن کاملTowards clustering-based word sense discrimination
This paper describes a series of experiments conducted to group similar words using context features derived from a corpus. The goal is to find an approach that would be suitable for cleaning the fuzzy WordNet synsets obtained by automatic translation of Serbian synsets into Slovene. Similar techniques have been used successfully by a number of researches already and they are attractive particu...
متن کاملA Fuzzy Clustering Approach to Word Sense Discrimination
This paper describes a novel approach to automatically categorize (i.e. cluster) a set of words in order to reflect their various senses and their relations of semantic similarity. We report on experiments on a set of Norwegian nouns that are represented by their co-occurrence profiles over various lexico-grammatical contexts extracted from corpora. With the purpose of capturing a notion of typ...
متن کاملA clustering-based Approach for Unsupervised Word Sense Disambiguation
Clustering methods have been extensively used in many Information Processing tasks in order to capture unknown object categories. However, clustering has been scarcely used as a sense labeling method for Word Sense Disambiguation (WSD), that is, as a way to identify groups of semantically related word senses that can be successfully used in a disambiguation process. In this paper, we present an...
متن کاملWord Sense Disambiguation in Information Retrieval
The natural language processing has a set of phases that evolves from lexical text analysis to the pragmatic one in which the author’s intentions are shown. The ambiguity problem appears in all of these tasks. Previous works tries to do word sense disambiguation, the process of assign a sense to a word inside a specific context, creating algorithms under a supervised or unsupervised approach, w...
