Abstract

Semantic similarity and mapping between ontologies are a crucial subject, which is just starting to be researched for ontologies written in Portuguese. Our study begins with SiSe (Similaridade Semântica) measure, an extension for the Taxonomic Overlap proposed by Maedche and Staab [1], which compares the similarity between terms of distinct ontologies through the analysis of the hierarchies where they are placed. SiSe development and evaluation, even bringing some interesting conclusions, point to continuing efforts, what is discussed here in the context of more recent proposals presented in the ontology mapping domain.
