Abstract
Web Service (WS) is used to support implementation of the distributed system and has already achieved interoperability with a variety of online platforms. This result is accomplished by loosely coupling many different services together. However, as the Internet environment becomes more and more complex, this objective also becomes more difficult to fulfill. For the purpose of maintaining correctness and automated WS composition, effectively managing the WSs and inter-WS interaction in the WS environment will be a major challenge for future infrastructure. In this paper, we propose a distributed infrastructure utilizing interactive techniques to achieve automated WS composition.
