Grammar-based message processing in web service composition

Web Services is a new architecture for information integration. More and more researchers are exploring Web Services related technologies from database aspect and software engineering aspect. Web Services Composition, which is composed of a number of basic services in order to implement complex business logic, is the key in Enterprise Application Integration (EAI). It is very common that data schema of interface messages is not exactly match among services, so users have to program in order to extract useful information from messages. There is little former work on this topic. This paper firstly defines the problem of interface message processing problem among services, and translates this problem into XML data processing problem. And then, grammar based approach is introduced for this problem. Experiments show that the above method is a flexible and efficient method for interface message processing.
