Ontology matching: from PropBank to DBpedia

While many systems such as those from Seddiqui and Aono (2009) and Cruz et al. (2009) use combinations of terminological and structural methods, the use of extensional and semantic methods in systems such as the one by Jean-Mary et al. (2009) have been largely unexplored (Pavel and Euzenat, 2012). Similarly to these approaches, we use a combination of alignment methods to create mappings between PropBank (Palmer et al., 2005) predicates and DBpedia (Auer et al., 2007) properties. In particular, we identify predicate– argument structures from Wikipedia articles to extract triples and use a combination approach of extensional and semantical methods during the matching process to align the extracted triples with an exisiting DBpedia dataset.
