PyDelphin 1.9.1

PyDelphin — Python libraries for DELPH-IN data

DELPH-IN is an international consortium of researchers committed
to producing precise, high-quality language processing tools and
resources, primarily in the HPSG syntactic and MRS 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.
Documentation, including guides and an API reference, is available here:
