Service-Oriented Knowledge Modeling Method and its Application

Knowledge services technology is becoming the important means to realize business intelligence and knowledge-based systems. Based on the development of grid and Web services technologies, using service-oriented architecture to build knowledge services is mentioned by many researchers. In this paper, a multi-perspective knowledge service description model (KSDM) for overall knowledge service modeling is proposed. The model pays attention to the executable part such as the dynamics, process, functionality and context of knowledge within knowledge service, which have not been addressed in existing knowledge service methods. Besides the basic configuration part, the model emphasizes definition of the knowledge contents part from four main perspectives that are domain knowledge, inference knowledge, task knowledge and context knowledge. For the application in real systems, a task-oriented architecture based on KSDM is proposed. And an implementation of mine resources evaluation knowledge service on spatial information grid is introduced
