Entailment, intensionality and text understanding


We argue that determining relations of entailment and contradiction between texts is a minimal metric for the evaluation of text understanding systems. We point out that widespread intensionality in natural language poses difficulties for the determination of such relations, and propose a layered architecture for dealing with them.
