Presentation at the CLEF 2023 conference

Members of our department, Ewelina Księżniak and Marcin Sawiński, took part in the 14th edition of the international CLEF conference, which is devoted to natural language processing and information retrieval. During this event, our scientists presented a method for detecting check-worthy claims, which achieved the best result in a competition organized by one of the workshops – CheckThat!Lab. The workshop and competition is devoted to detecting fake news using artificial intelligence.

More about this scientific research can be found in the article OpenFact at CheckThat! 2023: Head-to-Head GPT vs. BERT – A Comparative Study of Transformers Language Models for the Detection of Check-worthy Claims. This research is supported by the project “OpenFact – artificial intelligence tools for verification of the veracity of information sources and fake news detection” (INFOSTRATEG-I/0035/2021-00), granted within the INFOSTRATEG I program of the National Center for Research and Development, under the topic: Verifying information sources and detecting fake news.

The CLEF 2023 conference was held on September 17-22, 2023 in Thessaloniki (Greece). Conference website:
