Abstract

Linear tree-adjoining grammars (TAGs), by analogy with linear context-free grammars, are tree-adjoining grammars in which at most one symbol in each elementary tree can be rewritten (adjoined or substituted at). Uemura et al. (1999), calling these grammars simple linear TAGs (SL-TAGs), show that they generate a class of languages incommensurate with the context-free languages, and can be recognized in O(n4) time.
