A Model Driven Integration Architecture for Ontology-Based Context Modelling and Context-Aware Application Development

摘要

Context-awareness is a very important feature for pervasive services to enhance their flexibility and adaptability to changing conditions and dynamic environments. Using ontologies to model context information and to reason about context at a semantic level has attracted a lot of interest in the research community. However, most of the proposed solutions are ad hoc or proprietary. Therefore, employing standard approaches to formulate the development process becomes of importance. In this paper we examine how OMG's Model Driven Architecture (MDA) can be applied to tackle the issues of context modelling and Context-Aware Application (CAA) modelling and development. A Context Ontology Model (COM) is presented to model context information at two levels: upper-level and extended specific level. A Model Driven Integration Architecture (MDIA) is then proposed to integrate rigorous model specifications and generate CAA implementations either semi-automatically or automatically.
