Abstract
New energy conversion systems develop in environmental fields, and make its presence greater and greater. Data mining method was developed in order to investigate the mechanical and electrochemical degradations process of solid electrochemical devices under operating conditions. By using this method, it was possible to show and help the possibility that detailed degradation process can be evaluated visually and in real-time, even when applied to modules at the actual equipment level. On the other hand, as service science intends to scientifically reveal the mechanism and principle in order to create new energy devices, there emerges a lot of interdisciplinary approach of the brand-new field. While traditional marketing theories have provided frameworks of how to grasp, reach, and lure as many customers as possible, none of them can externalize the functional structure of any service knowledge, and offer methodology of handling them on computer. Aiming at computationally utilizing any service knowledge, we discuss service ontology by both analogies with functional ontology on ontology engineering, and by comparison with typical marketing theory. In addition, we introduce case study that are based on ontology, and show how to create knowledge by this theory.
