	_DESCRIPTION = """
	ElkarHizketak is a low resource conversational Question Answering
	(QA) dataset in Basque created by Basque speaker volunteers. The
	dataset contains close to 400 dialogues and more than 1600 question
	and answers, and its small size presents a realistic low-resource
	scenario for conversational QA systems. The dataset is built on top of
	Wikipedia sections about popular people and organizations. The
	dialogues involve two crowd workers: (1) a student ask questions after
	reading a small introduction about the person, but without seeing the
	section text; and (2) a teacher answers the questions selecting a span
	of text of the section. """
