Abstract
Over last decade, research in Web service discovery has brought a variety of techniques to find out responses for a Web service request. While the accuracy of matchmaking approaches has continuously improved, human contributions remain a key ingredient of the process. In this paper, we propose an approach called Crowd4WS (Crowdsourcing for Web service discovery) to complement and refine matchmaking approaches by using crowdsourcing techniques. We describe our approach and present the results of experiments on a known collection of RESTful services described with hRESTS.
