SIGMORPHON 2016 Shared Task: Morphological Reinflection
-------------------------------------------------------
Morphological analysis and generation of previously unseen word forms is a fundamental problem in NLP the accuracy of which is crucial for the success of many downstream tasks. Learning morphological inflection patterns from labeled data is a current challenge that is addressed by a number of papers published in various ACL-related venues.
To bring together researchers working on inference problems related to morphology, SIGMORPHON is hosting a shared task on morphological reinflection in 2016, held at ACL in Berlin, Germany.
In the shared task, participants will build systems that can learn to solve different reinflection problems using labeled data. An example of English reinflection is the conversion of "ran" to its present participle, "running". Specifically, a participant system needs to be able to (1) produce inflected word forms from a lemma, and (2) generate a specific inflected word form from some other labeled inflected form, and (3) generate inflected word forms from unlabeled word forms of the same lemma. All submitted systems will be compared on a held-out test set. Participation in all three tasks is not mandatory.
Participants will also be invited to describe their system in a short paper for the SIGMORPHON 2016 workshop. Additionally, the task organizers will write an overview paper with descriptions and summaries of the different approaches taken and their results.
Questions about the shared task can be sent to sigmorphon-shared-task-2016-organizers [at] googlegroups.com. More information about the task, including training and development data sets for the target languages of varying morphological complexity is available at the shared task home page:
