-_DESCRIPTION = """\
-This shared task (part of WMT20) will build on its previous editions
-to further examine automatic methods for estimating the quality
-of neural machine translation output at run-time, without relying
-on reference translations. As in previous years, we cover estimation
-at various levels. Important elements introduced this year include: a new
-task where sentences are annotated with Direct Assessment (DA)
-scores instead of labels based on post-editing; a new multilingual
-sentence-level dataset mainly from Wikipedia articles, where the
-source articles can be retrieved for document-wide context; the
-availability of NMT models to explore system-internal information for the task.
-
-The goal of this task 3 is to predict document-level quality scores as well as fine-grained annotations.
