A Survey on Dynamic Web Services Composition
Pei Zhang · 2007
As a new application model for decentralized computing, Web services is becoming an effective mechanism for the data and service integration on the Web. As an important method for flexible and rapid integration, dynamic Web services composition becomes a new hot research of complex distribute application in open and heterogeneous environment. Firstly, in this paper, several descriptions of Web services are analyzed, model and definition of dynamic Web services composition are presented. Then, combining current some composition platforms and frameworks, the theory of workflow based and AI planning based dynamic Web services composition as well as the typical application of the two composition methods are presented. And some other relative dynamic composite strategies are analyzed. In the end, the challenges of Web services dynamic composition and the future research work are proposed.
