Logica Universalis Webinar April 10, 2024 at 4pm CET Speakers: Didier Dubois, Henri Prade & Agnès Rico Title: "Modern vs. classical structures of opposition: A discussion" Abstract: "The aim of this work is to revisit the proposal made by Dag Westerst° ahl a decade ago when he provided a modern reading of the traditional square of opposition and of related structures. We propose a formalization of this modern view and contrast it with the classical one.We discuss what may be a modern hexagon of opposition and a modern cube, and show their interest in particular for relating quantitative expressions." https://link.springer.com/article/10.1007/s11787-024-00347-1 Associate organization: ADRIA-IRIT, CNRS https://www.irit.fr/en/departement/dep-artificial-intelligence/adria-team/ Presented by Didier Dubois and Henri Prade Chair : Sayantan Roy, Assistant Editor LU Everybody is welcome to join, register here: https://cassyni.com/events/LMSPiEvqN9JUsvzryqD1f3 Jean-Yves Beziau Editor of Logica Universalis and Organizer of LUW https://philpeople.org/profiles/jean-yves-beziau
