This study is a part of health promotion project which aims to make a receptive system for preventive healthcare considering the emerging technology breakthrough of the Internet of Thing (IoT) as the next generation of health promotion services. To be receptive, the system should have the capability in providing context-aware recommendation, motivating, and empowering its users. It is required for the system to be fully integrated with context sensors to recognize users’ dynamic contexts in which providing context-aware recommen-dation through analyzing the sensorial data as it is a part of users’ contexts. Ingrained with persuasive system, it enables the system to deliver the recommendation in an opportune moment, motivate the users to execute the recommendation, and maintain it. To empower the users, a mechanism to reduce users’ difficulties in doing the given recommendation have to be developed by offering them with the most appropriate service.
A conceptual architectural-design of context-aware IoT-enabled platform was deve-loped in this study following the requirement for a receptive system. A service-oriented context-aware middleware (SOCAM) architecture abstraction is adapted in the architectural design of the platform in order to build a system based on context-awareness and support the reusability of existing fragmented services. The modular architectural design with context provider as its part intends to build such platform supporting integration with IoT sensing networks and to support ubiquitous environment.
Furthermore, an approach towards the problems of service integration and service discovery to reduce user difficulties in executing the recommendation of healthy activities has been developed. Several methods in information retrieval such as TF/IDF and semantic-based similarity algorithm are developed in order to resolve the service discovery issues.
