The CoNLL–SIGMORPHON 2018 Shared Task: Universal Morphological Reinflection

The CoNLL–SIGMORPHON 2018 shared task on supervised learning of morphological generation featured data sets from 103 typologically diverse languages. It consisted of two separate scenarios. In Task 1, participating systems must inflect word forms based on labeled examples. In English, an example of inflection is the conversion of a citation form1 run to its present participle, running. The system is provided with
the source form and the morphosyntactic description (MSD) of the target form, and must generate the actual target form. Task 2 is a harder version of Task 1, where the system must infer the appropriate
MSD from a sentential context. This is essentially a cloze task, asking participants to provide the correct form of a lemma in context.
