Improving the Performance of Web Using Semantic Prefetching Methodology

Abstract: The growth of the World Wide Web has emphasized the need for improvement in user latency. One of the techniques that are used for improving user latency is Caching and an- other is Web Prefetching. Web prefetching is one of the techniques proposed to reduce user’s perceived latencies in the World Wide Web. The spatial locality shown by user’s accesses makes it possible to predict future accesses based on the previous ones. A prefetching engine uses these pre- dictions to prefetch the web objects before the user demands them. This paper proposed a semantic based prefetching methodlogy to improve the prefetch hit ration and minimize the user access latency so that the user requested data can be retrieved as fast as possible.
