Platforms, algorithms and AI: Issues and hypotheses in the mediatization perspective

Jairo Ferreira 18 inferences regarding the phenomena (social practices and discourses about these practices, from actors and institutions) and the epistemological approaches suggested, particularly about what is communicational in it, considering it as a mutation in media processes and whether this mutation demands new epis- temes in the research line Mediatization and Social Processes, differentiating epistemological and methodological displacements suggested by the “North” and “South” strands for the un- derstanding of these mutations. This book is a sample of interlocutions between the South and the North in research on mediatization, matured in these six seminars. They indicate advances towards the aware- ness of a point of differentiation and connection between epistemologies. Without the intension of exhaustion, we highlight axes of approximations and differentiation. One of the zones of differentiation is mediatization from the perspective of circulation and social semiosis, founded by Eliseo Verón. There are no strong references to the theories of signs in the perspectives of the north. This absence can be observed in the institutionalist current (in which Stig Hjarvard is a researcher of international reference) and in the sociocon- structivist currents (e.g., Couldry & Hepp, 2020). The currents of the north, when they approach the phenomenon of language, refer to discourse in a generic way, in an approach that often precedes discourse theories, semiotics, or even structural semiology. On the other hand, the issue of circulation (strong in the south strands) appears, in the texts of researchers from the north in a more generic way, without the intense and complex problematization observed in the southern currents (Fausto Neto, Ana Paula da Rosa, Viviane Borelli, Mario Carlón, and Jairo Ferreira), including the relationship between code, circulation and de-circulation (Aline Dalmolin). In this book, Göran Bolin’s chapter is a work of interlocution around these axes (sign and circulation), or even of referencing (as in Dalmolin, when she brings Braga’s thought to formulate her reflections). This ap- proach, still embryonic, is a good achievement of the Seminars on Mediatization. On the other hand, if the reflection on media, institu- tions, and actors is strong in Northern perspectives, it is also
