The concept1 of country has been widely used in all kinds of databases or systems. A commonly understood and unified schema for country entity is needed to knowledge organization, semantic association and deeply integration of the multi-source and heterogeneous data resources about country concepts. This paper proposes a computer understandable and computable Upper Country Ontology based on OWL and SKOS, with instances of 195 countries, 7 continents, 38 regions and more than 10 international organizations. The proposed ontology is expected to be used as knowledge middleware, supports identifying and indexing country entities, publishing open linked dataset, referencing country instance, SPARQL endpoint query and semantic reasoning and so on. |
