Quantifier Floating is one of the much studied phenomena in natural language where quantifying expressions may appear in places other than their original prenominal one. While its presence is especially prominent in languages such as Korean that allow more or less free word order, we find that there are nevertheless remarkable regularities in the way the language allows quantifiers to “float”, by examining various constructions in Korean including coordination, relative clauses, and embedded clauses. These regularities are captured syntactically in a combinatory categorial grammar (CCG) framework for Korean that makes use of all the levels of syntax, semantics, and discourse. We also describe an implemented query system that generates answers with contextually appropriate ellipsis in the domain of e-commerce.
