JCC_V3_N1_RP4 S. Salam M. Roja T.V. Rao Journal on Cloud Computing 2350-1308 3 1 24 29 E-Tree (Ensemble Tree), Data Stream, Web Monitoring Data Stream classification is one of the critical tasks in data mining. At the point when DataStream touches the base at a pace of GB/sec, we need to recognize spam, web observing and capacity. It is a troublesome operation and falls flat in the existing System. Actualizing two Algorithms namely, E-tree Algorithm (Ensemble-tree) and Avaricious Algorithm and Executing E-tree algorithm, the authors have maintained a strategic distance from the existing issues. Ensemble tree (Etree) takes care of extensive volumes of stream data and drifting. E-tree, Classifies and groups the Data Stream and stores the data effectively. Furthermore, foresee web checking and spam identification precisely. Controlling the web movement, the authors have actualized the greedy algorithm.
