Probabilistic Geospatial Ontologies
نویسنده
چکیده
Partial knowledge about geospatial categories is critical for knowledge modelling in the geospatial domain but is beyond the scope of conventional ontologies. Degree of overlaps between geospatial categories, especially those based on geospatial actions concepts and geospatial enitity concepts need to be specified in ontologies. We present an approach to encode probabilistic information in geospatial ontologies based on the BayesOWL approach. This paper presents a case study of using road network ontologies. Inferences within the probabilistic ontologies are discussed along with inferences across ontologies using common concepts of geospatial actions within each ontology. The results of machine-based mappings produced are verified with human generated mappings of concepts.

متن کاملFramework of semantic interoperability using geospatial ontologies
Semantics of geospatial information is necessary to ensure its interoperability and correct usage. Geospatial ontologies enable encoding such knowledge and enable reasoning mechanisms to estimate interoperability. The framework of interoperability for geospatial information using ontologies, presented in this paper, supports (i) building of ontologies, (ii) semi-automated, ontology-based mappin...

ion geospatial domain ontology Figure 2: The distinction between three types of concepts leads to geospatial domain ontologies which are not biased by implementation needs. For example, a town is often represented as a point feature in geospatial applications. But in the first place, the “real world” town has no ontological relation to the representational structure of a point. The domain of ge...
متن کاملExploring Visualization of Geospatial Ontologies using Cesium
In recent years, there has been a substantial increase in the usage of geospatial data, not only by the scientific community but also by the general public. Considering the diverse and heterogeneous nature of geospatial applications around the world and their inter-dependence, there is an impending need for enabling sharing of semantics of such content-rich geospatial information. Geospatial on...
متن کاملMatching geospatial ontologies
In recent years, multiple geospatial ontologies have been developed for a wide range of different spatial databases. In addition, the development of volunteered geographic information both challenges and provides opportunities to the traditional authenticated geospatial information. Though volunteered geographic information is typically not as reliable and structured as the authenticated geospa...
