Compositional Semantics for Relative Clauses in Lexicalized Tree Adjoining Grammars
Chung–hye Han · 2002
This paper proposes a compositional semantics for relative clauses in Lexicalized Tree Adjoining Grammars (LTAG). As explicated in (Joshi and Vijay-Shanker, 1999; Joshi and Kallmeyer, 2000), in the phrase-structure based compositional semantics the meaning of a sentence is computed as a function of meaning of each node in the tree. On the other hand, in LTAG based compositional semantics, the meaning of a sentence is computed
