Abstract

This work discusses the supporting role of ontologies for geosensor network data focusing on methods for linking geosensor network datasets with ontologies. A major benefit gained from this kind of linking is the augmentation of databases with generalization or specialization relations from an ontology. We present methods for linking based on a transportation application where data on vehicle position is collected from sensors deployed along a road network and stored in a geosensor database. A mechanism for linking, implemented as a tab widget within the Protégé ontology editor, is introduced. This widget associates data values from the geosensor database with classes in the ontology and returns linked terms (i.e., matches) to the user as a set of equivalence relations.
