Abstract: Petri net plays an increasingly important role in Web service composition due to its advantages at the description of concurrency and distribution system.To study Web service composition using Petri net,it is crucial to assure the association between parameters of single Web services.This paper first introduced the description of Web services using Petri net,as well as a Petri-net-based register system.Further more,the conception of data association was defined to determine the association between Web service arguments.Using data association,fusible places can be found and Petri net for Web service composition can be established by automatic sharing synthesis of Petri nets.Finally,an applying example was given about the usage of data association.

Key words: Petri net,Web service,Composition,Data association
