Multilingual Ontology Matching

Author: Cássia Trojahn dos Santos (


This material contains a minimal API that implements two basic methods for multilingual ontology matching:

  • Direct translation-based alignment
  • Indirect alignment (based on the proposal of Jung et. al., 2009)


Material: zip containing sources, libraries, and documentation


Based on two tests provided by OAEI benchmark (ontologies 101 and 206), a new Portuguese ontology is created, together its alignments to English and French ontologies.

Material: test case, sh to match the ontologies using the API
