NL Seminar Leave No Question Behind! Broadening the Scope of Machine Comprehension

Abstract
Despite remarkable progress in building Question Answering QA models, the scope of progress remains limited to niche dataset specific domains. How can we expand the scope of the problems that our models can address? In this talk, I discuss two instances of QA system design that cover a broader range of problems. In the first part, I introduce UnifiedQA, a single model that generalizes to multiple different QA formats multiple choice QA, extractive QA, abstractive QA, yes no QA. Then I will introduce ModularQA, a single system that addresses multiple multi hop reasoning datasets by leveraging existing single hop modules systems. For each system, I present empirical evidence on their better generalization and stronger robustness across datasets and domains.
