Study of Composing Web Service Based on SOA

摘要

Automated service composition refers to automating the entire process of composing a workflow. This involves automating the discovery and selection of the service, ensuring semantic and data-type compatibility. We gave some basic notions and recent research of Web Service, and then classified Web Service Composition approaches according to the methodology they used. Furthermore, we analyzed every approach's motivation and its shortages, as well as outlined the essential problems of Web Service Composition. Finally, we concluded and discussed the developing trends.
