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 over 20% relative error reductions when compared to non-neural methods. I will also discuss our first steps towards scaling the amount of data such methods can be trained on by many orders of magnitude, including semi-supervised learning via contextual word embeddings and supervised learning through crowdsourcing. Our hope is that these advances, when combined, will enable very high quality semantic analysis in any domain from easily gathered supervision.
