Resumo(s)
Geographic information available from multiple sources are moving beyond their local
context and widening the semantic difference. The major challenge emerged with ubiquity of
geographic information, evolving geospatial technology and location-aware service is to deal
with the semantic interoperability. Although the use of ontology aims at capturing shared
conceptualization of geospatial information, human perception of world view is not
adequately addressed in geospatial ontology. This study proposes ‘Conservation GIS
Ontology’ that comprises spatial knowledge of non-expert conservationists in the context of
Chitwan National Park, Nepal.
The discussion is presented in four parts: exploration of commonsense spatial knowledge
about conservation; development of conceptual ontology to conceptualize domain
knowledge; formal representation of conceptualization in Web Ontology Language (OWL);
and quality assessment of the ontology development tasks. Elicitation of commonsense
spatial knowledge is performed with the notion of cognitive view of semantic. Emphasis is
given to investigate the observation of wildlife movement and habitat change scenarios.
Conceptualization is carried out by providing the foundation of the top-level ontology-
‘DOLCE’ and geospatial ontologies. Protégé 4.1 ontology editor is employed for ontology
engineering tasks. Quality assessment is accomplished based on the intrinsic approach of
ontology evaluation.(...)
