Semantic Web Services Of Deviation Problem

Semantic Web Services is a hot research work, which is composed of Semantic Web and Web Service. Currently research work related to semantic web services is largely originated from semantic web groups, mainly based on OWL-S language, but this paper focuses on the composition research of semantic Web and knowledge engineering. In knowledge engineering, ontology is used to describe the certain field knowledge and problem-solving methods (PSMs). It is not only promoting the knowledge engineering more scientific and standardized, but also conducting the PSMs into semantic Web scope through the composition.In generally, knowledge-based system could be divided into two classes: analysis system and integration system. Analysis system generally includes classification, diagnosis, evaluation, monitoring etc, but there is not a common model in analysis system. Based on the even research of seminar and traditional analysis system, the paper expands the scope of analysis system, sum up as the deviation problem according to the quantity of actual knowledge and proposes the corresponding PSMs. Through abstracting the main concept of PSMs and analyze the relationship between concepts, the paper provides the composition framework of Semantic Web services of deviation problem, build an experimental knowledge-based Semantic Web Services which could be published on-line based on WSMO(Web Service Modeling Ontology), and study about how to achieve the automatic web services composition.The main works and innovation is as follows:(1) According to the quantity of domain knowledge, expand the traditional analytics system of knowledge engineering as deviation problem, and propose the corresponding PSMs.(2) Through the concepts analysis of PSMs, proposes the corresponding composition framework of semantic web services of deviation problem, transfers the deviation problem to the composition by a series of semantic web services. The composition framework represents as layered tree structure. To manage the execution control, expanded the combination operator which provide the implement foundation of transferring the web composition to executable process.(3) Based on the composition framework, embed the control operator by OCML (Operational Concept Modeling Language) in WSMO platform, build a motivation example which would be published online.(4) According to the feature of knowledge-based services, study how to achieve the automatic composition of knowledge-based Semantic Web Services, propose an approach to support the automatically composition and convert it into executable workflow by And/Or graph, and provides the architecture which could deal with the composition framework of deviation problem.(5) Knowledge management plat of semantic web services is the ultimate goal of our seminar. This paper proposes rough idea about plat, and discusses three key issues.
