Discovering and Improving Recovery Mechanisms of CompositeWeb Services

Abstract

One of the main challenges that encounter Web services is how to ensure reliable compositions. In this paper we present an approach that starts from a composite service effective executions to improve its reliability. Basically, we propose a set of mining techniques to discover its model and its transactional behavior from an event based log. Then, based on this mining step, we use a set of rules to improve its recovery mechanisms
