Hi Bruno, Actually I'm not going to answer your question and leave it for others who have developed tools to parse the pagecount files, but while we're on the topic just wanted to point out the "redirects" and title changes. This is something that a good number of people who work with the viewership data overlook. If the title of a page is changed, the history of the page will be moved under the new title and the old title will become a redirect page (normally). But the viewership data will be split. So if you want to, for example, now the viewership of a page with current title B and old title A, you have to add up the viewership to both pages within the period under study. Just something to note... and sorry if you're already doing this! Good luck, Taha On Thu, Jul 28, 2016 at 9:00 PM, Bruno Goncalves &lt;bgoncalves(a)gmail.com&gt; wrote: -- -- ==New Paper== Wikipedia traffic data and electoral prediction: towards theoretically informed models <http://epjdatascience.springeropen.com/articles/10.1140/epjds/s13688-016-0083-3> Taha Yasseri and Jonathan Bright EPJ Data Science, 5:22 (2016). ============= Dr Taha Yasseri http://www.oii.ox.ac.uk/people/yasseri/ Research Fellow in Computational Social Science, Oxford Internet Institute, Research Fellow in Humanities and Social Sciences, Wolfson College, University of Oxford, and Faculty Fellow, Alan Turing Institute for Data Science.
