METHOD FOR PREDICTING QUALITY OF WEB SERVICE

摘要

Provided is a method for predicting the quality of a Web service (QoS). The method comprises the following steps: step one, data collection, involving: each user locally collecting a QoS value, i.e. a QoS value; step two, normalization, involving: executing z-score normalization on the QoS value; step three, data disguising, involving: disguising the QoS value; step four, using neighbourhood-based collaborative filtering to process the disguised QoS value; and step five, result prediction, involving: predicting a result according to the QoS value subjected to collaborative filtering. The method can protect the privacy of a user and ensure the availability of data.
