QoS value prediction of web services is an important issue for service recommendation and selection. QoS value is an important factor for service selection because the quality of whole system is dependent on the QoS of single web service. In reality predicting the missing QoS value of web service using the existing information is a difficult problem. Collaborative Filtering (CF) is one of the most widely used methods which employ QoS values contributed by similar users to make predictions. So the previous QoS value contributed by the different users is used for the prediction and the evaluation of missing QoS values.
