This paper focuses exclusively on the specific nature of the semiotic project
developed in Greimas’s Structural Semantics, a project which needs to be distinguished from the rest of the semiotician’s work. The aim, in short, is to establish that the driving force of this text, from both the epistemological and heuristic
viewpoints, is based on three descriptive categories: text, genre and corpus, which
open up the perspective, not of textual or discourse semiotics, but of corpus semantics.
