Stefan Grünewald, Sophie Henning, Alexander Koller
Chart constraints, which specify at which string positions a constituent may begin or end, have been shown to speed up chart parsers for PCFGs. We generalize chart constraints to m…
Discovering User Groups for Natural Language Generation
Nikos Engonopoulos, Christoph Teichmann, Alexander Koller
We present a model which predicts how individual users of a dialog system understand and produce utterances based on user groups. In contrast to previous work, these user groups ar…
AMR Dependency Parsing with a Typed Semantic Algebra
Jonas Groschwitz, Matthias Lindemann, Meaghan Fowlie +2
We present a semantic parser for Abstract Meaning Representations which learns to parse strings into tree representations of the compositional structure of an AMR graph. This allow…
