Inference of lexical ontologies. The LeOnI methodology

Abstract

In this article we present a method for semi-automatically deriving lexico-conceptual ontologies in other languages, given a lexico-conceptual ontology for one language and bilingual mapping resources. Our method uses a logistic regression model to combine mappings proposed by a set of classifiers (up to 17 in our implementation). The method is formally described and evaluated by means of two implementations for semiautomatically building Spanish and Thai WordNets using Princeton’s WordNet for English and conventional English–Spanish and English–Thai bilingual dictionaries.
