Collaborative filtering (CF) is widely used to make a web service recommendation. The recommendation of the CF-based web service aims to predict the lost QoS values ​​of the web services. Although many methods of predicting QoS service have been proposed on the Internet in recent years, performance still needs to be significantly improved. First, current methods of predicting quality of service rarely consider the personal impact of users and services when measuring the similarity between users and services. Second, web service quality factors, such as response time and transition, are generally based on web services and users. However, prediction methods for the QoS-based service rarely took this observation into account. In this document, we suggest a custom CF method to mark a site for a web service recommendation. The proposed method promotes user sites and web services by determining neighbors similar to the intended user or service. The method also includes an improved measure of similarity with users and web services, taking into account their personal impact. To evaluate the performance of our proposed method, we conducted a complete set of experiments using a set of real world web service data. The experimental results indicate that our approach improves the accuracy of the QoS and its computational efficiency significantly, in comparison with the previous methods of cystic fibrosis.
