摘要 为了增加基于用户的协同过滤方法在预测Web服务质量时的相似性用户数目,进而提高Web服务的质量,首先构建一个用户相似性网络,并通过链接预测的方法找出潜在的相似性用户,最后综合应用相似性用户和预测出的潜在相似性用户预测用户的Web服务质量。实验表明,提出的方法在提高预测成功率的同时,还降低了预测的误差,因而适用于稀疏的Web服务质量预测。

英文摘要 In order to increase the number of neighbors in user based collaborative filtering method, and improved the QoS of Web service, this paper first constructed a user similar network, then found implicit neighbors based on link prediction in user similar network, and finally predicted QoS of Web service with both similar neighbors and implicit neighbors.The experiments show that, the proposed approach improves the successful rate and decreases the prediction error, and is suitable for predicting QoS of Web service in sparse data.
英文关键词 Web service; QoS; sparse matrix; link prediction
