We propose the task of unsupervised morphological paradigm completion. Given
only raw text and a lemma list, the task consists of generating the
morphological paradigms, i.e., all inflected forms, of the lemmas. From a
CoNLL-SIGMORPHON 2018 shared task focused on supervised learning and morphological generation for over 100 languages, with task 1, inflection task, receiving 27 submissions and task 2, the cloze task, receiving 6 submissions where most systems utilized neural components and improvements were seen from last year's inflection task.
