Abstract:
We introduce a first-order language for semantic underspecification that we call Constraint Language for Lambda-Structures (CLLS). A-structure can be considered as a-term up to consistent renaming of bound variables (ffequality); a constraint of CLLS is an underspecified description of a-structure. CLLS solves a capturing problem omnipresent in underspecified scope representations. CLLS features constraints for dominance, lambda binding, parallelism, and anaphoric links. Based on CLLS we present a simple, integrated, and underspecified treatment of scope, parallelism, and anaphora. 1
