A framework for automatic web service composition based on service dependency analysis

The practice of composing web services has received an increasing interest with the emerging application development architecture called Service Oriented Architecture (SOA). This PhD dissertation developed methods for dependency based automatic service composition technique. A top layer architecture with a composition engine is developed. The architecture gives a complete picture of dependency based automatic service composition. Process model generation sub-task of the developed architecture is formulated as a service dependency identification and analysis problem. And, a two-stepped method for automatic process model generation, given a set of candidate web service descriptions, is proposed.
