Sensor ontology building in semantic sensor web

Abstract

To address the shortcomings of existing sensor ontologies, such as lack of a unified ontology framework and being built completely manually, this work proposes the sensor ontology framework and algorithms for automatic sensor ontology update and extension. In addition, sensor discovery based on time, space and theme is implemented. Sensor core ontology and its update and extension are evaluated. The experimental result reveals that the proposed sensor ontology framework is feasible, and the algorithms for sensor ontology update and extension are effective. © 2012 Springer-Verlag.
