Selection of an appropriate Web service for a particular task has become a difficult challenge due to the increasing number of Web services offering similar functionalities. The functional properties describe what the service can do and the nonfunctional properties depict how the service can do it. Non-functional properties involving qualitative or quantitative features have become essential criteria to enhance the selection process of services making the selection process more complicated. Chaari et al. [8] proposed an ontological framework for modeling and exploiting non-functional properties. In this paper, we propose a simple Web services selection scheme based on user's requirement of the various nonfunctional properties and interaction with the system. The proposed framework utilizes user preferences as an additional input to the selection engine and the system ranks the available services based on the requirement. The method is validated using a popular Web services bench mark and the experiment results indicate that the scheme is useful and warrants further research
