摘要：Traditional Web service discoveries mostly proceed from perspective of Web service function attributes. Web service companies provide many similar services that have same functions. Quality of Service (QoS) reflects the ability of a service matching users’ needs and it is an important index for evaluating performance of Web service. Based on initial research results, this study proposes a clustering method of users and services according to users’ QoS. Users having same preferences are clustered into a user cluster and services with similar QoS information are clustered into a service cluster. According to the direction and weight that the user cluster prefers, this study recommends a best service cluster whose matching value is the biggest to the user cluster by computing the comprehensive QoS value.
