摘要:Web services are widely used in the business application development to achieve interoperability among standalone systems. Efficient and effective techniques are required to find and select required services among similar services which is an important task in the service-oriented computing. Ranking process which is part of Web service discovery system helps the users to find the desired services effectively. The existing research contribution for ranking process does not consider the user�s requirements which are an important factor to rank web services. In this work, vector-based ranking method is enhanced to consider user�s requirements. The vector-based model is selected because of its simplicity and high efficiency. The web services are evaluated on the basis of their similarity degrees to the optimal or the best values of various quality attributes. Experiments are conducted with real dataset and the improved algorithm is compared with the other approaches and it is found that the enhanced vector-based ranking method is efficient in terms of execution time to return the result set.
