Résume : Currently, Web services are available on Internet in a simple and easy way to use. However, a single service can not respond to a predetermined request by user. Thus, it is necessary to compose services, ie, organize them in a manner to achieve the goal automatically. The semantic web services increases the descriptions of web services using semantic annotations (eg ontology). There are different approaches to express the semantic aspect as OWL-S, WSMO, WSDL-S and a recent W3C recommendation SAWSDL (Semantic Annotations for WSDL and XML Schema). To address complexity, scalability and heterogeneity problems of Web Systems, the OMG has proposed the model driven approach MDA based on the concepts of models, metamodels and transformations. The method describes a process that guides the developer through various phases, starting with the models, and ending with a new compound that can be deployed and published.

Résume : Web services composition has emerged as a solution to answer the requester's requirements. However, the selection of an appropriate Web service has become a difficult task due to the number of Web services present on the Web and mostly they offer similar functionalities. User preferences are a key factor that can be used to rank candidate services and retain only the best ones. To improve the process of web service composition the authors propose a Case-Based Planning (CBP) approach based on preferences which uses successful experiences in past to solve similar problems at present or/and in the future. How to make a choice base on non-functional factors becomes a problem that need to be solved. This paper, argues that the selection should be considered in a global manner based on the user's preferences. The authors present a framework that deals with web service composition based on user preferences and CBP method. Results obtained offer more than a solution to the user and taking both functional and non-functional requirements.

Résume : Web service selection is an indispensable process
for web service composition. However it became a difficult
task as many web services are increased on the web and mostly
they offer similar functionalities, which service will be the best.
User preferences are the key to retain only the best services for
the composition. In this paper, we have proposed a web service
composition model based on user preferences. To improve the
process of web service composition we propose a case-based
planning approach with user preferences which uses successful
experiences in past to solve similar problems. In this paper we
integrate user preferences in the phase of selection, adaptation
and planning. Our main contributions are a new method of case
retrieval, an extended algorithm of adaptation and planning
with user preferences. Results obtained offer more than a
solution to the user and taking both functional and nonfunctional requirements.
