This paper presents a semantic and adaptive service for context-aware information management system for supporting ubiquitous computing applications in a smart vehicle space. In ubiquitous computing environments, systems consisting of different device types, operating systems, network interfaces, and communication protocols. These contexts change dynamically and the applications have to adapt their behaviors in terms of the contexts. In order to facilitate the realization of such ability, the software middleware platform is required to manage their context information effectively and satisfy qualities of context information required by applications. As a result, we suggest a semantic and adaptive service based on a QoS-based semantic ontology, which describes the non-functionality aspects of contexts such as life cycle, usability, accuracy, reliability to achieve adaptive context management. The paper introduces the QoS-based semantic ontology, and gives the design and implementation the semantic and adaptive context management service.
