Central Concerns and Questions

There has been a continuous need to ease the process of building distributed systems. Building such systems by integrating available systems and reusing resources and software in an automatic manner is proven to be a challenging problem due to the dynamic and heterogeneous nature of the software systems in today's environment.

Emerging Ideas and Initiatives

In this research, we investigate the research issues and related techniques within the Service Oriented Architecture (SOA) that enable and ease the discovery of needed Web services and the construction of a valid and efficient composite Web service using these services for a give service request. We also study related supporting techniques for service discovery and composition in SOA that make a better use of the large data set on the usage of Web services.
