Multilingual Wordnet sense Ranking using nearest context

要旨

In this paper, we combine methods to estimate sense rankings from raw text with recent work on word embeddings to provide sense ranking estimates for the entries in the Open Multilingual WordNet (OMW).The existing Word2Vec pre-trained models from Polygot2 are only built for single word entries, we, therefore, re-train them with multiword expressions from the wordnets, so that multiword expressions can also be ranked.Thus this trained model gives embeddings for both single words and multiwords.The resulting lexicon gives a WSD baseline for five languages.The results are evaluated for Semcor sense corpora for 5 languages using Word2Vec and Glove models.The Glove model achieves an average accuracy of 0.47 and Word2Vec achieves 0.31 for languages such as English, Italian, Indonesian, Chinese and Japanese.The experimentation on OMW sense ranking proves that the rank correlation is generally similar to the human ranking.Hence distributional semantics can aid in Wordnet Sense Ranking.
