Abstract

In this paper, we survey and review ontologies for context reasoning in context-aware computing environments. There are lots of data obtained from heterogeneous sensors. In order to acquire the meaning of the massive data, ontologies for contextual information should be applied to a context-aware middleware. Accordingly, it is necessary to develop context ontology methodologies for context reasoning. Context ontology can identify specific classes of contexts and relations for context-aware applications. Also, the context ontology can represent any form of contextual information. In addition, the context ontology can make inference by specifying contextual information.
