Process Mediation in Semantic Web Services

The Semantic Web Services initiatives are aiming to develop auto- matic and dynamic solutions for the semantically described Web services dis- covery, invocation and execution. The automation of all this activities is possible only if both the requestor and the provider of a service are semantically describ- ing the requested and the provided functionalities, as well as the behavior they are going to have during the service's invocation. However, several mismatches may occur, on several levels: data, process or functionality. This paper is focusing on overcoming the process heterogeneity problems, from the processes compati- bility point of view.
