ESIP has been collecting and hosting Earth and Environmental ontologies in the ESIP Ontology Portal. But these ontologies have very different degrees of quality and curation. One way to ascertain this degree of quality is to locate terms with similar semantics between two ontologies and upload these mappings into the Portal. This work describes how we provide backend mappings between classes in ontologies using Agreement Maker Light, a winning algorithm from the Ontology Alignment Evaluation Initiative. We use the OWL equivalence relationship to discover similarities between concept labels. The mappings, in the form of rdf triples are published in the Purdue University Research Repository and given Digital Object Identifiers.
