How to Identify Temporal Configurations with Semantic Tools – Advantages and Difficulties in Associating Prospero and OMA: This article focuses on the opportunities for the sociologist in the development and describing methodologically successive socio-discursive configurations from the perspective of sociology attentive to public issues or collective actions. Noting that it is difficult and costly to reproduce thematic analyzes whenever the corpus evolves and refines research questions, the challenge is to develop computerized tools to accompany the researcher’s reasoning while obliging reflexive thought and permitting the production of data to test hypotheses. With an experimental approach coupling the features of the Prospero and TraMineR (in R software) computer programs, we propose a research protocol which aims to obtain information on dynamic, heterogeneous and complex processes that we would like to be able to equate for at least some aspects. The path is to establish typologies of sequences from semantic data and their optimal matching.
