247 Mediatization, circulation and social semiosis: references for critical analysis of platforms and algorithms1 Midiatização, circulação e semiose social: referências para análise crítica de plataformas e algoritmos Jairo Ferreira2 Abstract: In this chapter, we present, in section one (subdivided into three topics), the construction of the concept of mediati- zation in Verón, starting with his foundational formulations on circulation3. In this section, we propose that Verón’s construc- tion has topical variations, reported synthetically in section two, aiming our inferences on what mediatization is according to his work. In the second section, we expand the inferences to the analysis of platforms, algorithms, and artificial intelligence, broadening the reflections with the concepts of simulations, maps and territories4. Keywords: mediatization; circulation; platforms; algorithms, artificial intelligence. 1 This systematization, based in South America, of the epistemologies of media- tization – transversalities, differentiations and complementarities – is the ob- ject of ongoing research, contemplated with the support of CNPq, CAPES and FAPERGS. 2 POSCOM-UFSM professor.
