Contributive categorization – seminar 1

Here is the video recording of the first « contributive categorization » seminar of the 2013-2014 season. To watch a chapter, just click on a yellow segment below the video player, this action will open a new window with a “+” button that activates descriptions (in French). It is also possible to annotate the video online, if you have a [Lignes de Temps] account. At last, for people who did not follow the seminar from the beginning, we propose you a selection of short chapters (translated in English) in the sidebar menu.
