An Adaptive PPM Prediction Model Based on Pruning Technique

A New Prediction Model Based on Web Access Behavior

“…The PPM (Prediction by Partial Match) prediction models [3][4][5][6][7][8][9][10][11][12][13][14] based on tree-like structure belong to multiple highorder Markov models; the DG(Dependency Graph) models [15][16][17][18][19][20]based on graphlike structure belong to 1-order Markov models. In many applications, first-order Markov models are not very accurate in predicting the user's browsing behaviors, since these models do not look far into the past to correctly discriminate the different observed patterns.…”
