Adapting I/O Parameters of Web Services to Enhance Composition

Web service chaining forms one of the basic operation during web service composition. To decide whether services can be chained, semantic matching between the I/O is usually evaluated. In this paper we propose an approach considering possible adaptation of output data before it is consumed as input by other service. We also define the corresponding rules based on which it is evaluated if the chaining is possible or not. Moreover, we deal also with the affect on workflow and service description, and their execution.
