A Composability Framework for Semantic Web Services

Abstract

Existing techniques for Web service composition generally require dealing with low level programming details, thus making the process of composing services demanding for composers [16, 36, 118, 160, 191]. Composers need to identify the way operations are interconnected, services are invoked, and messages are mapped to one another. To deal with this issue, we propose a model, called composability model, to check whether operations can be com- bined together, hence avoiding unexpected failures at run time. Composability refers to the process of checking if Web service operations to be composed can actually interact with each other [18].
