Collaborative Prediction of Web Service Quality Based on User Preference and Service
The prediction of Web service quality plays an important role in improving user services. Therefore, it has been one of the most popular topics in the field of Internet services. In traditional collaborative filtering methods, the differences in personalization and preferences of different users have been ignored. In this paper, for different types of quality of service (QoS) attributes, different extraction rules are applied to extract the user preference matrices from the original Web data, and the negative value filtering-based Top-K method is used to merge the optimization results into the collaborative prediction method. In doing so, the individualized differences have been fully exploited, and the problem of inconsistent QoS values has been resolved. The experimental results demonstrate the validity of the proposed method. Compared with previous methods, the proposed method
performs better, and the results are closer to the real values.
