Scope and Situation Binding in LTAG using Semantic Unification

  title={Scope and Situation Binding in LTAG using Semantic Unification},
  author={Maribel Romero and Laura Kallmeyer},
This paper sets up a framework for Lexicalized Tree Adjoining Grammar (LTAG) semantics that brings together ideas from different recent approaches addressing some shortcomings of LTAG semantics based on the derivation tree. The approach assigns underspecified semantic representations and semantic feature structure descriptions to elementary trees. Semantic computation is guided by the derivation tree and consists of adding feature value equations to the descriptions. A rigorous formal… CONTINUE READING
