Ontology based context aware model

Abstract

Top-Down approach is followed while developing a Context Model which means first application and then its functionality will be defined. Once this is setup, required context models are developed. In this paper, we have presented the comparison of existing context ontologies on the basis of different parameters and also provided an ontology based context model which defines the generic concepts and also provides the extensibility for adding domain-specific ontology. This model will use Extended Hierarchical Censored Production rule (EHCPR) which is a scheme for representing knowledge.
