Quality of web service, especially the reputation, has become a benchmark to differentiate the services and providers. Unfortunately, the current reputation research in the field of web services don’t reasonably and correctly think about the randomicity and fuzziness which has been the basic issue in the relative research area about trust. We proposed two novel metrics to qualify the reputation of web services and providers. We designed two kinds of trust model based on cloud model theory to describe the randomicity and fuzziness of the two metrics. Furthermore, a formalized calculation was provided to obtain the trust degree of services requestors to web services and providers.
