High complexity of understanding user's current situation is a crucial barrier to popularize context aware applications on smartphone. In order to overcome this barrier, we propose a context aware engine which eases the development of intelligent applications. Key feature of the engine is dynamic reconfiguration of the knowledge base depending on the current environments using linked data. We vali...Show More
Despite the increasing request for intelligent applications with the heavy use of smart phone, little of them are available in daily life. One reason must be the high complexity of understanding user's situation. For application (app) developers, knowing user's context usually takes much more time and efforts than taking some useful actions. To help developing intelligent apps, we have proposed a ...Show More
This paper proposes MISSA, a novel middleware to facilitate the development and provision of stream-based services in emerging pervasive environments. The stream-based services utilize voluminous and continuously updated data streams as their input. The characteristics of data streams bring new requirements on the development and provision of the services. To satisfy the requirements, a unique ser...Show More
This paper describes an approach for connecting basic functionalities of distributed consumer electronics and telecommunication equipment to compose so called virtual devices for better user experience. Basic device functions can be their capabilities such as keyboard, mouse, display, storage, as well as communication and messaging capabilities. The paper gives a short introduction of the idea and...Show More
