L'impossible clôture des corpus médiatiques: la mise au jour des observables entre catégorisation et contextualisation

Abstract

With a view to analyzing the way the mass media deal with specific "discourse moments" (such as the debates on GMO's), two stages are drawn up. First, a survey is made of the descriptive categories that prove necessary to extract "observables", which are located along texts and documents, and also to set up the "sub-corpora" they bring up. But in the purpose of contextualizing these data, we need to make use of the operating notion of dialogism, with its various forms of actualization. Thus, in a second stage, it is shown how the first exploratory corpus can be expanded to interdiscourses, which come up as reminders of previous discourses and facts: this interdiscursive memory bank, built up by the media and within the media, takes us back to the history of the relations between science, nature and society.
