| Abstract: | Presents a novel Web transaction identification method based on Dempster-Shafer(D_S) evidence theory.This method fuses multiple features of Web session to decide whether user's interest is changed.Furthermore,light-computation features are used to develop an efficient fusion mechanism to guarantee high performance of the algorithm.Compared with other transaction identification methods,experimental results showed that our method achieves a high performance. |
