Toward a Ubiquitous Personalized Daily-Life Activity Recommendation Service with Contextual Information: A Services Science Perspective

In recent years services science has been an emerging discipline that aims to promote service innovation and increase service productivity by aligning scientific, management, and engineering perspectives. It emphasizes that service innovation should be able to create value for both services providers and consumers. To realize the core thinking of services science, that is, high value and high productivity, service design has to incorporate many factors into its consideration. Based on the ideas of this new research field, we develop a personalized daily-life activity recommendation service that includes information behavior, business value, and technology architecture as our service design considerations. Our service can be requested under a ubiquitous environment and include users´ contextual information which is an important factor in information behavior. With regard to IT architecture, we use the service-oriented architecture (SOA) that provides the flexibility and extensiveness of technology as well as permit new innovative services to be easily added.
