Comparing Verb Synonym Resources for Portuguese

Abstract. In this paper we compare verb synonym information contained in four public-available lexical-semantic resources for Portuguese: TeP, PAPEL, Wiktionary and OpenThesaurusPT. We quantify the extent to which verb synonymy information in four resources overlaps, and we quantify how much novelty each resource in comparison to the others. We demonstrate that the four resources vary significantly in respect to verb synonymy information. Also, we show that by merging the four resources we can obtain a more comprehensive verb thesaurus. Finally, we suggest that resource merging may actually be required in order to avoid performance and evaluation bias that arise from coverage problems when using only one of these resources.
