A Context Model by Ontology and Rule for Offering the User-Centric Services in Ubiquitous Computing

Ubiquitous technology is taking charge of a core role for changing physical space which consists of devices in adaptive and distributed computing environment. It is required that various devices for each system, service and function which support moving users and fast changing context. Recent research work of the context-aware systems has focused on the ontology and reasoning. However, in the most part of context-aware systems the service management between users have not been adequately considered in respect of interoperation with classes. The context-aware systems utilize the ontology as knowledge repository, rules for organizing the services, and the agents for managing the services. Recent research work of the context-aware systems has focused on the ontology and reasoning. Although existing ontology consists of each class by functions and each class is connected by relationship in the physical environment. However the structure of context model is insufficient for classification and grouping to express the situations, environments, and services. We propose of this study is to do an ontology context service model using F-logic which is permits context information management through effective context modeling in home network.
