Web structure optimization technique plays a significant role in reducing latency and improving the access efficiency. This paper presents the Web Hierarchy Model (WHM) which is constructed based on user access path. Then the Web Conceptual Mode (WCM) is obtained by clustering pages in the same hierarchy according to the pages similarity. According to the experiments and analyzes
WCM can show the structure of Web clearly under moderately clustering. Furthermore the model is implemented in web prefetching system
in the aspect of prefetching efficiency
the clustering algorithm used in this model is superior to the traditional method and it is feasible and efficient.
