A critical path in the development of natural language understanding (NLU) modules lies in the difficulty of defining a mapping from words to semantics: Usually it takes in the order of years of highly-skilled labor to de- velop a semantic mapping, e.g., in the form of a semantic grammar, that is comprehensive enough for a given do- main. Yet, due to the very nature of human language, such mappings invariably fail to achieve full coverage on unseen data. Acknowledging the impossibility of stat- ing a priori all the surface forms by which a concept can be expressed, we present GsG: an empathic computer system for the rapid deployment of NLU front-ends and their dynamic customization by non-expert end-users. Given a new domain for which an NLU front-end is to be developed, two stages are inv...
