Abstract: Currently, researchers have proposed several sequential association rule modes for predicting the next HTTP request. These researches focus on using sequence and temporal constrains for pruning to improve prediction precision. This paper provides a comparative study on different kinds of sequential association rules for Web document prediction, gives algorithms on mining sequential association rules, which is based on sequence and temporal different combination. The performance of all such algorithms has been compared on a real Web log dataset. Based on the comparison, using analysis of variance method, the effect of sequence and temporal information on influencing the precision of prediction is explored.
