モーリス・メルロー＝ポンティ
Algirdas Julien Greimas (1917–1992) developed a structural version of semiotics named, "generative semiotics", trying to shift the focus of discipline from signs to systems of signification. His theories develop the ideas of Saussure, Hjelmslev, Claude Lévi-Strauss, and Maurice Merleau-Ponty.
