AUTHORS : Suchithra M      Ramakrishnan M            
ABSTRACT :

Web service discovery process locates appropriate web services as per user preference from web.  Since abundant numbers of web services are supplied for a single request, it becomes essential to rank them so that most relevant services can be supplied to the requester.  In order to rank web services, various features are used and non-functional properties of a web service plays a vital role in this ranking process.  In this paper, simple web services ranking algorithm is proposed which utilizes non-functional requirements. First web service filtering process is applied on selected web service set to remove unwanted and redundant web services. Then ranking process is applied on remaining web services and web service with highest score is supplied to the requester.  Experimental results show that the proposed method outperforms the traditional methods of web service discovery process.
