Modeling questions and responses in discourse

This post contains course materials for my 2016 NASSLLI course, ‘Modeling questions and responses in discourse’. This course presented and compare theories of responding to questions from the perspective of both linguistics, focusing on formal pragmatics, and computer science (‘QA’). Post-hoc caveat: The state of the art in QA has drastically changed since 2016 (and was already in flux then, to some degree).
