Geographic Ontologies Production in GREASE-II
| Resumo: | This report presents the development of authoritative geographic knowledge and related conceptualization tools in the project GREASE-II. The feature concept, an abstraction for geographical entities, is the centre of the conceptual model, which is oriented towards a representation of geographic data as interlinked web resources. The conceptualization tools are the Geographic Knowledge Base (GKB) system (version 2.1), a system for geographic knowledge management, and the Geo-Net vocabulary for describing geographic knowledge. Both contribute to the production of the new version of the geospatial ontology of Portugal, Geo-Net-PT 02. The innovations introduced since version 1.0 of the GKB system and Geo-Net-PT 01 include a formalization of the model, the support for generic property sets, detailed information provenance, better geographic descriptions and the definition of Geo-Net vocabulary, a domain vocabulary. |
