Update or wait: How to keep your data fresh (2016, methodology): “ policy Finally, in Section VI, we conclude the paper. II. RELATED WORK The age-of-information was deﬁned as a metric of data freshness as early as 1990sin the studies of real-timedatabases [4], [23]–[25]. In recent years, queueing theoretic techniques were used to evaluate the age-of-informationin ”
Crawling the Hidden Web (2001, background): “Traditional PIW crawlers use metrics such as crawling speed, scalability [10], page importance [6], and freshness [5], to measure the effectiveness of their crawling activity.”
Design and implementation of a high-performance distributed Web crawler (2002, background): “Good recrawling strategies are crucial for maintaining an up-to-date search index with limited crawling bandwidth, and recent work by Cho and Garcia-Molina [11] [10] has studied techniques for optimizing the " freshness " of such collections given observations about a page's update history.”
The Evolution of the Web and Implications for an Incremental Crawler (2000, methodology): “The forwarded URLs are included in AllUrls , if they are new.”
Design and evaluation of a continuous consistency model for replicated services (2000, background): “These techniques can be vaguely categorized into two classes: Relaxing consistency among replicas to reduce required communication (replica control) [3, 6, 19, 26, 32, 35] and relaxing consistency for transactions on a single site to allow increased concurrency on that site (concurrency control) [2,”
Searching the Web (2001, methodology): “In [19] we also show how to obtain the optimal refresh policy (better than uniform or any other), assuming page changes follow a Poisson process and their change frequencies are static (i.”
What's new on the web?: the evolution of the web from a search engine perspective (2004, background): “4Note that [13] suggests that search engines optimizing for overall freshness should, when resources are scarce, ignore high-frequency modifications so that resources can be used more profitably, even when all modifications are assumed to incur the same degree of change.”
