An ORM Based Context Model for Context-Aware Computing.

Context-aware applications are the future of modern smartphones. Now we have mobile devices with enough sensing and processing capabilities but combining them and developing a context-aware application for mobile devices is still a challenging task for developers. Context-aware middleware support is a solution to reduce the complexity in developing context-aware applications. Context modeling is one of the key requirement for a successful context-aware middleware for context representation and reasoning. This paper presents a new Object-Role Modeling (ORM) based context model which uses the advantage of modern graph databases and overcomes the problems associated with previous context models including their lack of context reasoning ability and poor spatial and temporal context modeling support.
