  Most businesses these days use the web services technology as a medium to
allow interaction between a service provider and a service requestor. However,
both the service provider and the requestor would be unable to achieve their
business goals when there are miscommunications between their processes. This
research focuses on the process incompatibility between the web services and
the way to automatically resolve them by using a process mediator. This paper
presents an overview of the behavioral incompatibility between web services and
the overview of process mediation in order to resolve the complications faced
due to the incompatibility. Several state-of the-art approaches have been
selected and analyzed to understand the existing process mediation components.
This paper aims to provide a valuable gap analysis that identifies the
important research areas in process mediation that have yet to be fully
explored.
