Abstract

In this paper, we present the use of semantic caching in the environment of schema-based super-peer networks. Different from traditional caching, semantic caching allows the answering of queries that are not in the cache directly. The challenge of answering the queries using the cache is reduced to the problem of answering queries using materialized views. For this purpose, we implemented the MiniCon-algorithm, which delivers the maximally-contained-rewritings of a posed query based on the stored views. Using simulation and experimental results, we will show the benefit of semantic caching.
