[DELPH-IN](http://delph-in.net) is an international consortium of
researchers committed to producing precise, high-quality language
processing tools and resources, primarily in the
[HPSG](http://hpsg.stanford.edu/) syntactic and
[MRS](https://github.com/delph-in/docs/wiki/RmrsTop) semantic
frameworks, and PyDelphin is a suite of Python libraries for
processing data and interacting with tools in the DELPH-IN
ecosystem. PyDelphin's goal is to lower the barriers to making use of
DELPH-IN resources to help users quickly build applications or perform
experiments, and it has been successfully used for research into
machine translation (e.g., [Goodman, 2018]), sentence chunking
([Muszyńska, 2016]), neural semantic parsing ([Buys & Blunsom, 2017]),
natural language generation ([Hajdik et al., 2019]), and more.
