The current context-aware mobile application approach lacks a standardized method for knowledge representation that can handle intelligence effects, such as automatic, dynamic, and intelligent support for mobile context-awareness applications. To tackle these intelligence issues, this research introduces the Semantic-aware Service into Cloud Computing Architecture (SSCCA) as a common scheme to enable intelligent context-aware mobile applications using a fundamental cloud service model. SSCCA combines Cloud Computing and Semantic Web research to facilitate the development of intelligent cloud computing applications. To validate the proposed approach, a Smart Context-aware Invoice Platform (SCIP), an intelligent cloud computing application built on SSCCA, is implemented to gather personal electronic invoices and offer context-aware mobile services on demand.
