Tree-Adjoining Grammar

abbreviation(s): TAG
definition: Tree-Adjoining Grammars (TAGs) are tree rewriting systems. The grammar components are (lexicalised) elementary trees, which are composed by substitution and adjunction operations. The syntactic representation consists of the constituent tree built by composition of elementary trees, and a derivation tree, which records the dependencies between elementary trees as established by substitution and adjunction operations. A basic linguistic assumption underlying TAG is that elementary trees encode basic predicate-argument structure. This extends to long-distance dependencies, which are "localised" in (lexicalised) elementary trees.
