摘要
针对Web服务推荐时间和结果精确度方面存在的不足,本文提出一种基于QoS(Quality of Service)历史记录的Web服务推荐算法(Web Service Recommendation Algorithm based on Historical QoS,WSRAHQ)。首先,建立基于欧氏距离的Web网络用户兴趣度相似簇,提高Web服务推荐的精确度;然后,根据用户的QoS历史记录,利用多元线性回归,得到新用户的Web服务推荐结果,完成Web服务推荐。仿真结果表明了该方法有效性。
Aiming at the accuracy problem of Web service recommend time and result, a Web Service Recommendation Algorithm based on the Historical QoS record(WSRAHQ) is proposed in this paper. First, based on the Euclidean distance, the similar cluster of Web network users" interest degree is built to improve the accuracy of Web service recommendation. Then, the new user's Web service recommend result is given to finish the Web service recommendation based on the users" QoS Historical record and multiple linear regression. The simulation results show its efficiency.
