Abstract

In this paper, we present a novel approach for materializing dynamic web pages by exploiting content dependencies and user access patterns. We introduce two new semantic-based data freshness metrics and show that our approach out-performs traditional balancing QoS-QoD approaches in terms of server throughput, increased data freshness and scalability. In our evaluation we use a real-world experimental system that resembles an online bookstore web database application.
