%X Compared with others in service discovery,the selection of service in workflow has its own characteristic.At the present,the selection of the service is always according to the requirement of the single service in most researches, which didn't consider the constraint relationships and the coordination problems among the services.But in workflow, those problems are also the important factors that impact the selection of the service.The paper put forward a new al- gorithm used in service selection,which based on rule and compatibility comparison.The purpose of the rules that guide the selection process is to reflect the relationships among the services.After removing some services provided by the advertiser which don't obey the rule,the algorithm compares the compatibility between the candidate service and other related services in the following step.In the end,a service which satisfied the requirements both of its own and the en- tire workflow is obtained.
