Efficient Service Composition Architecture Using AND/OR Graph

摘要：

This paper proposes an approach for automated composition of Web services using the And/Or graph and designs a corresponding layered architecture.The composition approach which decomposes tasks into smaller And,Or subtasks in And/Or graph bases on the similarity algorithm to find out optimized solution graph.Additionally,we embed the Sequence-And node to support the transition from the And/Or solution graph to executable workflow,and Interface node to provide user preferences and correctness inspection during the composition execution.The architecture corresponding to the composition approach above consists of four layers including the Knowledge Ontology,Task Template,Mediator,and Web Service from up to bottom in the order.A motivation example throughout this paper provides a preliminary experimental illustration which clearly shows the benefits of our approach.
