Dataset Card for CHANGE-IT

Dataset Summary

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 during the Evalita 2020 evaluation campaign. 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.

Style Transfer

The following table is taken from Table 4 of the original paper, where a pointer-network architecture is used as a baseline to perform style transfer in two settings. In the rep2gio variant the system is trained to summarize Repubblica headlines from full texts (vice versa for gio2rep), and the style transfer is performed by summarizing full texts of the other newspaper in the source newspaper's headline style. avg is the average of the two settings.

	HH	AH	Main	Compliancy
rep2gio	.649	.876	.799	.449
gio2rep	.639	.871	.435	.240
avg	.644	.874	.616	.345

Here Main, HH and AH are all BERT-base models trained to evaluate the quality of style transfer as follows:

• Main: the model is trained to classify a generated headline either as ilgiornale or repubblica, achieving ~80% F1 score on gold data. Tests whether the transfer has been successful.
• Headline-Headline (HH): the model is trained to check the compatibility between original and generated headlines. Tests whether the generation is coherent with the reference.
• Article-Headline (AH): the model is trained to check the compatibility between original fulltext article and generated headlines. Tests whether the generation is coherent with the source article.

The final metric, Overall compliancy, is a binary metric that is positive if the other three metrics match (Main decision is reversed, HH and AH predict match), and negative otherwise. Refer to Section 3 of the original paper for more details.

Dataset Structure

Data Instances

A sample from the test split of the ilgiornale config is provided below. The other configuration, ilgiornale, has the same structure.

{
  "id": 0,
  "headline": "Ucraina, coalizione della Timoshenko denuncia irruzione nella sede",
  "full_text": "Rimane alta la tensione in Ucraina , dove da giorni i manifestanti scendono in piazza per protestare contro la decisione del presidente Viktor Yanukovich, che ha deciso di congelare l'accordo di associazione con l'Unione Europea. Il momento è molto delicato. L'opposizione teme una repressione violenza della protesta, con le forze speciali che hanno costretto i manifestanti a Kiev ad allontanarsi dalla sede del governo, per ripiegare su piazza Indipendenza. Il leader d'opposizione Vitaly Klitschko ha invitato il presidente a non utilizzare la forza, se non vuole avere il sangue dei manifestanti sulle sue mani. Nel frattempo il presidente Yanukovich ha aperto alla possibilità di un dialogo, annunciando per domani un incontro con i suoi due predecessori, Leonid Kuchma e Viktor Yushchenko. Ieri un milioni di persone sono scese in piazza, scaduti i due giorni di ultimatum dati al governo per indire nuove elezioni, I manifestanti hanno rovesciato la grande statua di Lenin posta sul boulevard Shevchenko. Piazza Indipendenza (Maidan Nezalezhnosti) resta il punto più caldo della capitale. Qui sono state erette barricate davanti agli ingressi della metropolitana, nel tentativo di preparsi a un'azione della polizia, che al momento non ha però preso iniziative contro i dimostranti. In serata Batkivshcyna, la coalizione dell'ex premier Yulia Timoshenko , ha denunciato l'irruzione di almeno venti agenti della polizia antisommossa nel proprio quartier generale. Il portavoce della polizia, Olga Bilyk, ha smentito: \"Né la polizia di Kiev, né la Berkut - ha dichiarato - hanno condotto operazioni nella sede\".",
