Since working at JHU, I have become more and more involved in computational cognitive science, focusing on interpretation. This is to some degree a return to my roots; I have an undergraduate degree in Computer Science. I’m interested in three main questions in computational semantics and Natural Language Understanding:
- What does a computationally implemented theory of linguistic semantics/pragmatics look like?
By “computationally implemented”, I mean that the theory is not just expressed mathematically, but in terms of running code. To address this first question, I have worked on building implemented versions of such models, and on providing tools for others to do so. See The Lambda Notebook project for more details.
- Can converging evidence from computational models and NLP-oriented data sets contribute to linguistic theory, and if so, how?
- Can linguistic theory contribute to applied Natural Language Understanding projects, and if so, how?
These questions I have addressed in collaboration, especially Ben Van Durme, and Aaron Steven White. See also The Decompositional Semantics Initiative for more details on the overarching project, as well as my work on Lexical Semantics and the semantics of Clause-embedding predicates (Reisinger et al. 2015; White et al. 2016; White & Rawlins 2016; White, Rawlins & Van Durme 2017; White & Rawlins 2018; White et al. 2018; White et al. 2019; White & Rawlins 2019). As part of this, I have been a co-PI on funded collaborative grant projects from DARPA as part of the LORELEI, AIDA, and KAIROS projects, as well as from the NSF.
Related teaching: I have occasionally taught seminars within Cognitive Science on these topics, and together with Ben Van Durme, offer every few years a graduate seminar called Event Semantics in Theory and Practice, that brings together linguistic event semantics with NLU annotation and models. At ESSLLI 2017, Aaron Steven White and I co-taught an advanced course on computational lexical semantics. At NASSLLI 2020, I will teach a 3-day mini-course on implementing semantic compositionality.
