“…In previous works on web dynamics, suitable datasets had to be crawled first, which is tedious and can only be done for shorter periods (Cho and Garcia-Molina, 2000;Fetterly et al, 2003;Koehler, 2002;Adar et al, 2009). With access to existing archives, more recent studies of the Web were conducted retrospectively on available data (Hale et al, 2014;Agata et al, 2014;Alkwai et al, 2015), commonly with a focus on a particular subset, such as national domains or topical subsets. These kinds of works are typical data-centric tasks as they require access to archived raw data or metadata records.…”
