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 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.
