Word Sense Disambiguation: A Case Study on the Granularity of Sense Distinctions

نویسنده

  • DAN TUFIŞ
چکیده

The paper presents a method for word sense disambiguation (WSD) based on parallel corpora. The method exploits recent advances in word alignment and word clustering based on automatic extraction of translation equivalents and is supported by a lexical ontology made of aligned wordnets for the languages in the corpora. The wordnets are aligned to the Princeton Wordnet, according to the principles established by EuroWordNet. The evaluation of the WSD system was performed using three different granularity sense inventories. Key-Words: Alignment, Lexical ontology, Parallel corpora, Sense inventories, Word sense disambiguation, wordnet

Evaluating the Word Sense Disambiguation Accuracy with Three Different Sense Inventories

Comparing performances of word sense disambiguation systems is a very difficult evaluation task when different sense inventories are used and, even more difficult when the sense distinctions are not of the same granularity. The paper substantiates this statement by briefly presenting a system for word sense disambiguation (WSD) based on parallel corpora. The method relies on word alignment, wor...

Meaningful Clustering of Senses Helps Boost Word Sense Disambiguation Performance

Fine-grained sense distinctions are one of the major obstacles to successful Word Sense Disambiguation. In this paper, we present a method for reducing the granularity of the WordNet sense inventory based on the mapping to a manually crafted dictionary encoding sense hierarchies, namely the Oxford Dictionary of English. We assess the quality of the mapping and the induced clustering, and evalua...

Different Sense Granularities For Different Applications

This paper describes an hierarchical approach to WordNet sense distinctions that provides different types of automatic Word Sense Disambiguation (WSD) systems, which perform at varying levels of accuracy. For tasks where fine-grained sense distinctions may not be essential, an accurate coarse-grained WSD system may be sufficient. The paper discusses the criteria behind the three different level...

Reducing the Granularity of a Computational Lexicon via an Automatic Mapping to a Coarse-Grained Sense Inventory

WordNet is the reference sense inventory of most of the current Word Sense Disambiguation systems. Unfortunately, it encodes too fine-grained distinctions, making it difficult even for humans to solve the ambiguity of words in context. In this paper, we present a method for reducing the granularity of the WordNet sense inventory based on the mapping to a manually crafted dictionary encoding sen...
