This paper presents an encoding of Generation-TAG (G-TAG) within Abstract Categorial Grammars (ACG). We show how the key notions of G-TAG have a nat- ural interpretation in ACG, allowing us to use its reversibility property for text gen- eration. It also offers solutions to several limitations of G-TAG. 1 Motivations G-TAG (Danlos, 1998; Danlos, 2000) is a formal- ism based on the Tree Adjoining Grammar (TAG) formalism (Joshi et al., 1975; Joshi and Schabes, 1997) dedicated to text generation. It focuses on providing several notions to support useful data structures, such as g-derivation trees or lexical databases, to effectively relate a surface form (a derived tree or a string) to a conceptual represen- tation. An actual implementation in ADA was first provided for French (Meunier, 1997)...
