Toward a ubiquitous personalized daily-life activity recommendation service with contextual information: a services science perspective

In recent years, services science has emerged as a discipline of increasing importance, and one that aims to promote service innovation and increase service productivity by aligning disparate scientific, management, and engineering perspectives. It emphasizes that service innovation should be capable of creating value for both service providers and consumers. To realize the core thinking of services science, that is, attaining 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 services can be requested in a ubiquitous environment and include users’ contextual information which is an important factor in information behavior. With regard to IT architecture, we use service-oriented architecture (SOA) that provides the flexibility and extensiveness of technology, as well as permits new innovative services to be easily added.
