Semantic Webs, and decision support system.

In this paper, we describe an overview of the decision support system for rocket launch operation, focusing around Semantic Web Services that allow us to develop complex, large-scale, and globally distributed systems. In rocket launch operation, several parties who share interests and problems participate together in problem solving process against contingent events. The support systems for rocket launch operation that involve different participants must allow different knowledge, diverse business rules, and heterogeneous values of parties. Whereas the Service Oriented Architecture (SOA) once seemed to be a solution, it has become clear that it does not satisfy our requirements. We took up a challenge of building the support systems by means of Semantic Web Services. We have developed an OWL processor, a web agent, and various ontologies for rocket launch operation. We have designed the system architecture in which sub modules are built as Web Services so that user agents integrate them and perform agent tasks in order to help users according to various ontologies
