Researchers have developed a new framework for analyzing longitudinal web crawls, which are sequential samples of an evolving URL population. This framework introduces the "discovery curve" to measure the cumulative URL footprint over a sliding window of crawls. By comparing the discovery curve with pairwise containment analysis, the researchers identified disagreements in projections when applied to Common Crawl and the German Academic Web archives. These discrepancies suggest a two-component model of the web, featuring a persistent core alongside a dynamic shell, which better reconciles the observed data. AI
