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.
