Abstract: Web service recommendation has become a hot yet fundamental research topic in service computing. The most popular technique is the Collaborative Filtering (CF) based on a QoS values. With increasing presence and adoption of Web services on the World Wide Web, Quality-of-Service (QoS) is becoming important for describing nonfunctional characteristics of Web services. Several approaches to web service selection and recommendation via collaborative filtering have been studied, so here we are going to do survey of these techniques with pros and cons of techniques. Also based on these reviews we are going to propose a new technique to predict web service selection based on known and unknown QoS values which we explain in our future work.

Keywords: Web Service, Service Computing, Collaborative filtering, QoS values.
