A Novel Method for Web Service Composition Based on Extended BDI

Web Service Composition (WSC) has been a hot research topic in the past decade because it can carry out complex tasks. The main methods to study WSC include workflow, process algebra and semantics. It's very possible that user's goal is not consistent with WSC's goal. For this, a new method of WSC based on BDI (Belief-Desire-Intention) has been provided. In this method, Belief and Desire are mapped into the environment and the goal of web service (and user) respectively. Intention and WSC are determined by them. An improved BDI model has been applied to WSC and dynamic evolution of established processes. At last, a classic example in web service, travel service process, is utilized to illustrate the consistency between WSC's goal and user's goal.
