Semantic Cache Mechanism for Heterogeneous Web Querying
Boris Chidlovskii, Claudia Roncancio, Marie-Luise Schneider
In Web-based searching systems that access distributed information providers, efficient query processing
requires an advanced caching mechanism to reduce the query response time. The keyword-based querying is
often the only way to retrieve data from Web providers, and therefore standard page-based and tuple-based
caching mechanisms designed for conventional databases turn out to be inefficient for such a task. In this
work, we develop a mechanism for efficient caching of Web queries and the answers received from
heterogeneous Web providers. We also report results of experiments and show how the caching mechanism
is implemented in the Knowledge Broker system.
