Abstract: Personalization, advertising, and the sheer volume of online data generate a staggering amount of dynamic web content. In addition to web caching, View Materialization has been shown to accelerate the generation of dynamic web content. View materialization is an attractive solution as it decouples the serving of access requests from the handling of updates. In the context of the Web, selecting which views to materialize must be decided online and needs to consider both performance and data freshness, which we refer to as the Online View Selection problem. In this paper, we define data freshness metrics, provide an adaptive algorithm for the online view selection problem, and present experimental results.
