Data

The competition is over, but the data is still available here.

Evaluation

Main performance measure is accuracy on a balanced set of articles. In addition, we measure precision, recall, and F1-score for the hyperpartisan class. Please find the SemEval leaderboard here.

Ongoing Submissions

When you work on this task and publish your code on Github, send us a mail and we will add it to our list. Since the dataset is public as of December 2021, you are no longer required to use TIRA for accessing the dataset.

To kickstart new approaches, we provide a random baseline to illustrate the output of a submission and a term frequency extractor to illustrate how to read the dataset. For features, see the code from our ACL'18 publication for inspiration.

Grand Prize

In order to encourage developers to share their software so that everyone can profit from their work, we announced a grand prize of $1,000 to the best-performing submission that had its code published open source before the SemEval conference (which has been held at NAACL-HLT on June 6-7 in Minneapolis, USA).

The grand prize has been won by team bertha-von-suttner (Ye Jiang, Johann Petrak, Xingyi Song, Kalina Bontcheva, Diana Maynard from the University of Sheffield, United Kingdom). Well done!
