	_DESCRIPTION = """\
	WikiAuto provides a set of aligned sentences from English Wikipedia and Simple
	English Wikipedia as a resource to train sentence simplification systems.

	The authors first crowd-sourced a set of manual alignments between sentences in
	a subset of the Simple English Wikipedia and their corresponding versions in
	English Wikipedia (this corresponds to the manual config in this version of the
	dataset), then trained a neural CRF system to predict these alignments.

	The trained alignment prediction model was then applied to the other articles in
	Simple English Wikipedia with an English counterpart to create a larger corpus
	of aligned sentences (corresponding to the auto and auto_acl configs here).
