Web services composition based on user requirement

Under the environment of user's varied requirement, research on User requirement-driven composition of Web services becomes more and more important. The traditional systems of web services composition don't support variability of user's requirement. Therefore, we introduce user's requirement into system of web services composition and extend the modules of composition system. In this paper, we research on the methods of web service composition, design web services composition framework based on user's requirement, and describe the composition module in detail.
