46 - Parsing with Traces, with Jonathan Kummerfeld

TACL 2017 paper by Jonathan K. Kummerfeld and Dan Klein. Jonathan
tells us about his work on parsing algorithms that capture traces
and null elements in sentence structure. We spend the first third
of the conversation talking about what these are and why they are
interesting - if you want to correctly handle wh-movement, or
coordinating structures, or control structures, or many other
phenomena that we commonly see in language, you really want to
handle traces and null elements, but most current parsers totally
ignore these phenomena. The second third of the conversation is
about how the parser works, and we conclude by talking about some
of the implications of the work, and where to go next - should we
really be pushing harder on capturing linguistic structure when
everyone seems to be going towards end-to-end learning on some
higher-level task?
