_DESCRIPTION = """\ | |
The CHANGE-IT dataset contains approximately 152,000 article-headline pairs, collected from two Italian | |
newspapers situated at opposite ends of the political spectrum, namely la Repubblica (left) and | |
Il Giornale (right), with the two newspapers equally represented. The dataset has been used in the context | |
of the CHANGE-IT task (https://sites.google.com/view/change-it) during the Evalita 2020 evaluation campaign | |
(http://www.evalita.it/2020). CHANGE-IT is a generation task for Italian – more specifically, a style transfer | |
task for headlines of Italian newspapers. Given a (collection of) headlines from one newspaper, namely | |
Il Giornale (G) or La Repubblica (R), it challenges automatic systems to change all G-headlines to headlines in | |
style R, and all R-headlines to headlines in style G. Although the task only concerns headline change, the dataset | |
comprehends both the headlines as well as their respective full articles. | |
