چکیده (انگلیسی):

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.
