Here we investigate a fundamental problem for computational semantics: scope ambiguities. These are semantic ambiguities that can arise in syntactically unambiguous expressions, hence they pose a problem for our compositional approach to semantic construction. We illustrate the problem, and present four (increasingly more sophisticated) solutions: Montague's use of quantifier raising, Cooper storage, Keller storage, and a more recent constraint-based method called Hole Semantics. We present implementations of both the storage approaches, and of hole semantics.
