WN-Toolkit: Automatic generation of WordNets following the expand model

Abstract

This paper presents a set of methodologies and algorithms to create WordNets following the expand model. We explore dictionary and BabelNet based strategies, as well as methodologies based on the use of parallel corpora. Evaluation results for six languages are presented: Catalan, Spanish, French, German, Italian and Portuguese. Along with the methodologies and evaluation we present an implementation of all the algorithms grouped in a set of programs or toolkit. These programs have been successfully used in the Know2 Project for the creation of Catalan and Spanish WordNet 3.0. The toolkit is published under the GNU-GPL license and can be freely downloaded from http: //lpg.uoc.edu/wn-toolkit.
