Bootstrapping a Portuguese WordNet from Galician, Spanish and English Wordnets

摘要

In this article we exploit the possibility on bootstrapping an European Portuguese WordNet from the English, Spanish and Galician wordnets using Probabilistic Translation Dictionaries automatically created from parallel corpora. The process generated a total of 56 770 synsets and 97 058 variants. An evaluation of the results using the Brazilian OpenWordNet-PT as a gold standard resulted on a precision varying from 53% to 75% percent, depending on the cut-line. The results were satisfying and comparable to similar experiments using the WN-Toolkit.
