We have embedded Tree Adjoining Grammars (TAG) in a feature structure based unification system. The resulting system, Feature Structure (FTAG), captures the principle of factoring dependencies and recursion, fundamental to TAG's. show that FTAG has an enhanced descriptive capacity compared TAG formalism. consider some restricted versions this system possible linguistic stipulations can be made. briefly describe calculus represent structures used by extending on work Rounds, Kasper [Rounds et al. 1986, 1986] involving logical formulation structures.
