Invited Talk: End-to-end Deep Learning for Broad Coverage Semantics: SRL, Coreference, and Beyond

Speaker: Luke Zettlemoyer

Deep learning with large supervised training sets has had significant impact on many research challenges, from speech recognition to machine translation. However, applying these ideas to problems in computational semantics has been difficult, at least in part due to modest dataset sizes and relatively complex structured prediction tasks.

In this talk, I will present two recent results on end-to-end deep learning for classic challenge problems in computational semantics: semantic role labeling and coreference resolution. In both cases, we will introduce relative simple deep neural network approaches that use no preprocessing (e.g. no POS tagger or syntactic parser) and achieve significant performance gains, including up to 20% relative error reductions over non-neural methods. I will also briefly discuss our efforts for crowdsourcing large new datasets that should, in the very near future, provide orders of magnitude more data for training such models. Our hope is that these two advances, when combined, will enable very high quality semantic analysis in any domain from easily gathered supervision.

This is joint work with Luheng He, Kenton Lee, and Mike Lewis
