Abstract:

A content-and-structure-based Markov model is presented in this paper for the purpose of Wet） pre-fetching. The traditional Markov model is a history -based model which applies the statistical information to Web pre-fetching. The model presented in this paper gets a more precise result by adjusting the transition matrix in the traditional Markov model and improves the service quality of Web servers （QoS）.Experimental results show that the proposed  pre-fetching model has better performance.

Key words: web mining, web pre-fetching, Markov model
