G-TAG  ,  is a Tree Adjoining Grammar (TAG) based formalism which was specifically designed for the task of text generation. Contrary to TAG, the derivation structure becomes primary, as pivot between the conceptual representation and the surface form. This is a shared feature with the encoding of TAG into ACG. Laurence Danlos (Alpage Inria project), Aleksandre Maskharashvili, and Sylvain Pogodalla have shown how to recast the G-TAG formalism into ACG, relying on the reversibility properties of the later  ,  ,  .
