Computer Science Department Colloquium: Learning Natural Language Semantics with Heterogeneous Supervision

Abstract: 

Although we now have vast amounts of data available to us on the Web and elsewhere, it is often not clear how to genuinely leverage the richness of all this data. For natural language text, we typically need new human-labeled training data for each new combination of language, style, and domain. A model trained on movie reviews, for instance, will not work as well when applied to news articles. In this talk, I argue that we will need to jointly draw on multiple very heterogeneous kinds of data to move towards the next level of intelligent information systems.
The talk will showcase several of our results on exploiting auxiliary kinds of data for additional supervision. This includes techniques to exploit patterns in large amounts of unlabeled text, techniques to exploit large knowledge graphs as background knowledge, as well as techniques for self-supervision.
