The emergence of web applications has encouraged us to have much recent research on data caching. In our proposed work we have given a new strategy, dynamic hash mapping technique which gives fast information retrieval semantically with the cache. This increases the speed up in the information retrieval for semantic caching which is a method of data caching where it is rule based. The semantic caching technology can help to improve the efficiency of XML query processing in the Web environment. Unlike from the traditional tuple or page-based caching systems, semantic caching systems exploit the idea of reusing cached query results to answer new queries based on the query containment and rewriting techniques. The primary contribution of this article is to revisit the performance of semantic caching by this new mapping technique, which increases the efficiency in information retrieval in the semantic caching system. Our proposed method gives enhanced performance by reduced network traffic and searches the exact information from a large database, which is crucial, in a range of applications, especially in network-constrained environments. © 2007 IEEE.
