Replication Challenge is an exciting opportunity to get in touch with researchers from prominent research institutions and work together on a replication study of a selected work.

The activity is designated for early stage researchers (PhD students, research-oriented master students or other research enthusiasts) and focuses on topics falling within the scope of the DisAI project, namely:

  • multilingual language technologies
  • multimodal natural language processing
  • trustworthy artificial intelligence

while preferably covering (but not limited to) the domain of:

  • disinformation combating 

Each involved participant will be assigned a mentor from the leading partners. Together they will select a scientific paper (related to project topics) and replicate the research described therein. This way, the early-stage researchers will get better acquainted with the state-of-the-art in their field of study and gain practical research experience. The involved participants will have 3 months to replicate the selected research work. 

Each researcher will prepare a final report on the achieved results and submit it according to the instructions below (please scroll down for more info about the submission process).

The activity will culminate with a 1-day workshop, where the participants will present the results of their work. In the replication study, the participants and their mentors are encouraged to extend the replicated work with some novel interesting ideas, so their results can be published to the scientific community as well.

To participate in the replication study, please apply according to the instructions below. Approximately 10 early stage researchers will be selected after balancing the interest and mentors capacity.

Mentors and Research Works to Replicate

Note that the list of papers for replication is not exhaustive. You can propose your own paper when applying for the Replication Challenge, which can be considered by the mentors (UPDATED).


Fill in this form and indicate your interests. We will contact you with the decision, eventually containing information about mentor and research work assignment.

Results submission

After finalising the replication study, participants are obliged to submit a report summarising the achieved results.  

Submit the report by the submission date of the run you are involved in by email to using the template.

After submission, be prepared to receive feedback and instructions to provide a camera ready version.
