La formation de la chronique boursière dans la presse quotidienne française (1801-1870) : Métamorphoses textuelles d'un journalisme de données

Abstract : The mediatization of stock exchange activities has stirred a renewed interest in social sciences. This doctoral thesis tackles this topic through its historical development : it aims to describe the codification of a journalistic writing. In France, the stock exchange section has its Anno Dominici : on the 29th January 1838, the businessman and saint-simonian thinker Isaac Pereire launches a « Revue de la Bourse de Paris » in the Journal des débats. Twenty years later, each significant French daily has recruited a stock exchange chronicler. The main purpose of our work consist in identifying the factors that brought a shapeless text into a standard journalistic section. The subtitle of this thesis addresses three subsequent ambitions : to clarify the general setting that has allowed the creation of financial journalism, to analyze the establishment of a vintage form of “data journalism” and, then, to indicate that this older form of “data journalism” has been read as a set of data. The massive digitization of old newspapers has created the opportunity to study wider corpora. We developed an application, Pyllica, to scrap the collections of the French National Library and were able to store in a database all the weekly stock exchange sections published in the Journal des Débats from 1838 to 1870. The use of text mining techniques has allowed to determine precisely the evolution of stylistic and editorial motives. This thesis thus appears as a general contribution to the digital study of newspaper poetics.
