Extending the WN -Toolkit: dealing with polysemous words in the dictionary-based strategy (2016)

Abstract: In this paper we present an extension of the dictionary-based strategy for wordnet construction implemented in the WN-Toolkit. This strategy allows the extraction of information for polysemous English words if definitions and/or semantic relations are present in the dictionary. The WN-Toolkit is a freely available set of programs for the creation and expansion of wordnets using dictionary-based and parallel-corpus based strategies. In previous versions of the toolkit the dictionary-based strategy was only used for translating monosemous English variants. In the experiments we have used Omegawiki and Wiktionary and we present automatic evaluation results for 24 languages that have wordnets in the Open Multilingual Wordnet project. We have used these existing versions of the wordnet to perform an automatic evaluation.

## introduction 1.the wn-toolkit the wn-toolkit 1 @xcite is a set of programs developed in python for the automatic creation of wordnets following the expand model @xcite , that is, by translation of the variants (words) associated with the princeton word-net synsets. the toolkit also provides some free language resources. these resources are preprocessed so they can be easily used with the toolkit. the wn-toolkit implements the following strategies for wordnet creation: the wn-toolkit also provides some resources, as dictionaries and preprocessed bilingual corpora. the open multilingual wordnet foot_0 (omw) @xcite provides free access to several wordnets in a common format. we have performed experiments for 24 languages out of the 28 available wordnets. in
