Abstract: Raising the number of services is emerging on the Web Development to get the relevant service-relevant data become too big to be effectively processed by traditional approaches. So Arise the Big Data Knowledge for challenge environment in the Mash ups. Clustering-based Collaborative Filtering approach (Club CF) is planned recruiting similar services in the same clusters to recommend services collaboratively (Recommender Service System).Technically this approach is enacted around two stages: In first stage, the available services are divided into small-scale clusters in logic for further processing. In second stage, a collaborative filtering algorithm is imposed on one of the clusters. The number of the services in a cluster is much less than the total number of the services available on the web, it is used to reduce the online execution time of collaborative filtering.
