Authors profiling in Corsican autonomist press during the interwar period. Stylometric analysis and topic modeling on "A Muvra"

With the emergence of nationalism in the 19th century came regionalist movements to assert and claim cultural particularities. Corsica fitted in very well with this dynamic and even presented itself as a favourable location for the development of such ideas. The centralisation of the State around a strong capital and the policies of assimilation of the indigenous populations on the border with France led certain players to defend these particularisms. It was in this context that the Corsican autonomist newspaper A Muvra was born in May 1920 in Paris, under the impetus of Petru and Matteu Rocca. For almost 19 years, hundreds of authors participated in the writing of this massive dialectal work. The aim of this dissertation is to carry out author profiling, i.e. to determine the style and subjects covered by an author. To do this, we carry out authorship attribution stylometry on texts using pseudonyms before completing these analyses with topic modelling, indexing of latent topics in a corpus of texts. The aim is to gain a better understanding of the complex sociology behind this rich and varied newspaper, through the use of computational methods.
