With the unprecedented and dramatic development of Web services in recent years, designing novel approaches for efficient Web service prediction has become of paramount importance. Quality of Service (QoS) plays a critical role in Web service recommendation. However determining QoS values of Web services is still a challenging task. For example, some QoS properties (e.g., response time, through...

Clustering has been proposed in numerous researches on web services due to its ability in enhancing computational efficiency. The objective of this paper is to present a review on web services clustering and to propose fuzzy clustering of web services’ based on quality of service (QoS). A total of 49 manuscripts, collected from ISI, SCOPUS and Google Scholar indexing databases, were critically ...

Web Service (WS) discovery is a critical problem hindering web service technology proliferation. The current solution, based on catalog-style browsing, provides no control over the quality of registered services. Application of matching techniques for WS retrieval is still under investigation. The objective of this work is the design of a framework to improve WS discovery. Our approach is based...

Given the increasing applications of service computing and cloud computing, a large number of Web services are deployed on the Internet, triggering the research of Web service recommendation. Despite of service QoS, the use of user feedback is becoming the current trend in service recommendation. Likewise in traditional recommender systems, sparsity, cold-start and trustworthiness are major iss...

QoS prediction is critical to Web service selection and recommendation, with the extensive adoption of Web services. But as one of the important factors influencing QoS values, the geographical information of users has been ignored before by most works. In this paper, we first explicate how Probabilistic Matrix Factorization (PMF) model can be employed to learn the predicted QoS values. Then, b...

With the prevalence of Web service, QoS is playing a more and more important role in service evaluation, recommendation and selection. In most previous works, it is often assumed that the delivered QoS of a Web service is often determined by service provider, not service consumer. However, in the practical service execution environment, Web services usually work in an interactive mode with serv...
