A MOBILE AGENT BASED APPROACH FOR AUTOMATING "DISCOVER-COMPOSE" PROCESS OF SEMANTIC WEB SERVICES

Nowadays, the focus is not only on how to exchange data between companies but also on how to exchange services between them or between companies-customers in order to minimize IT charges and increase their profit. Thus, web services are an adequate solution for the e-business thanks to their interoperability and reusability. The combination of web services and semantic technology, which are called Semantic Web Services (SWS), allows their discovery-composition-invocation process to be automatically performed by programs or intelligent agents. However, this process is still a challenging task that includes several issues such as the complexity of finding and composing distributed SWS. In this study we present a mobile agent based approach to discover and compose SWS in a distributed environment and extend some algorithms related to this field. The article reports examples and experimental results in order to illustrate as well as to assess the benefits of the proposed approach.
