Аннотация:This article presents recent developments in the Geneva modular and interactionist approach to discourse organization. The first section analyses the main epistemological, theoretical and methodological properties of the Geneva Model by examining its relationship to data, communicative action, complexity and discourse organization, and then outlines the Geneva Model's modular methodology. The second section of the article focuses on a text extract from a service encounter and applies some aspects of the modular methodology to the analysis of request sequences. The authors argue that requests cannot be reduced to the utterance of single speech acts but are best described as complex discourse practices linking praxeological information, conceptual knowledge and textual competence.
