An ontology of the physical geography of Portugal

Abstract

Com o advento da Web Semântica é cada vez mais premente desenvolver novas formas de partilha de conhecimento que melhorem a interoperabilidade entre sistemas de informação geográfica (SIG). A modelação e representação do conhecimento geográfico sob a forma ontológica é uma das novas possibilidades. Esta dissertação estende uma representação ontológica, de acesso livre da geográfica de Portugal, a Geo-Net-PT01, acrescentando-lhe, aos já caracterizados domínios da geografia humana e da web portuguesa, o domínio da geográfica física. Para tal, foi incorporado no meta-modelo de informação pré-existente suporte para exprimir informação geográfica geo-referenciada numericamente. Desenvolveu-se uma metodologia para produção de modelos ontológicos incorporando o conhecimento do domínio da geografia física recorrendo ás fontes de produção de informação geográfica existentes. Esta metodologia foi utilizada na produção de uma nova versão da ontologia geográfica de Portugal, a Geo-Net-PT02, que agora incorpora dados sobre mais cerca de 24.000 entidades geo-referenciadas do território português.

The advent of the Semantic Web raised the need for development of new methodologies for information sharing that improve interoperability among geographic information systems (GIS). The modeling and representation of geographic knowledge in the ontologic form is one of the new possibilities. This dissertation extends an open source representation of the geography of Portugal, Geo-Net-PT01, adding to the previously characterised domains of the human geography and the Portuguese Web, the domain of physical geography. To that purpose, the existing information meta-model was extended with support for expressing geo-referenced information in numeric form. A method for production of ontologic models incorporating the knowledge from physical geography from existing geographic information producers. This methodology was used in the production of a new version of the geographic ontology of Portugal, Geo-Net-PT02, which now incorporates data on over 24,000 geo-referenced entities in the Portuguese territory.
