Abstract:

With the rapid development of internet technology, Web services are becoming more widespread in the recent years, but the traditional Web services discovery mechanism can not satisfy the requirements of clients due to its limitations．Meanwhile, current researches mainly focus on QoSbased Web services model and computation, but neglect services management. To address the problem, a trusted management mechanism is proposed based on natural attenuation and user feedback, which can eliminate the invalid services and provide reference evidence for the clients to select the best service．Through the mechanism, the usefulness and usability of the Web discovery system can be improved.
