Ontology matching with CIDER: Evaluation report for the OAEI 2008 (2008)

Jorge Gracia, Eduardo Mena

Abstract. Ontology matching, the task of determining relations that hold among terms of two different ontologies, is a key issue in the Semantic Web and other related fields. In order to compare the...

Web-based Measure of Semantic Relatedness (2008)

Jorge Gracia, Eduardo Mena

Abstract. Semantic relatedness measures quantify the degree in which some words or concepts are related, considering not only similarity but any possible semantic relationship among them. Relatedness...
