Resumo(s)
Background: Geo-Net-PT is a geospatial ontology representing the Portuguese territory and the relations between the several locations within in. Yahoo! GeoPlanet (TM) is a geospatial ontology that covers the whole world. To diminish the effects of repeated information, we propose an alignment between the administrative part of these two ontologies based on name similarity and physical closeness.
Results: After running the matching process, 16,814 matches were found, corresponding to 33% of the considered features in Geo-Net-PT and to 75% in Yahoo! GeoPlanet (TM). Among these, there are correct matches for each of the 18 districts and 308 municipalities. Only 1% of the matches failed the validation process.
Conclusions: This alignment represents a step further for the exploitation of geospatial ontologies, since it enables the mapping of annotation in documents and other resources from GeoPlanet (TM), a broad ontology, to Geo-Net-PT, a specific ontology for Portuguese geography.
