At the KES 2025 international scientific conference, papers authored by our researchers were presented, reporting the results of research on the evolution of scientific trends in blockchain technology and on the quality and distribution of data visualizations in the Polish Wikipedia.
During Researchers’ Night 2025, the staff of the Department of Information Systems conducted workshops titled “Operation InfoVerification” that were presented in the engaging form of a field game. The event introduced participants to the process of verifying information and identifying fake news. The workshops combined elements of adventure, investigation, and logic-based challenges, immersing participants in the fascinating world of fact-checking.
The paper on automatic analysis of Wikipedia content neutrality, authored by our researchers, was presented at IJCAI 2025 (the 34th International Joint Conference on Artificial Intelligence). The event took place on 16-22 August 2025 in Montreal, Canada.
During the Wikimania 2025 conference, the results of scientific research on the comparative analysis of Wikipedia articles on climate change in different language editions were presented. By leveraging open datasets, the study assessed the quality of articles and compared their popularity in various languages. For example, an analysis of over one billion internal links (wikilinks) on Wikipedia enabled the identification of the most frequently cited articles in each language edition.
A new paper by our researchers has been published on the Springer website. It explores the sentiment of Wikipedia articles about companies using a range of artificial-intelligence models. The study set out to determine how well each model copes with assessing the sentiment of Wikipedia’s characteristically long articles, and to examine how that sentiment varies across industries and article-quality classes.
A research prepared by scientists from our Department was presented at Wiki Workshop 2025. The study delivers a comprehensive, topic-based analysis of Wikipedia articles across 55 language editions and employs an original approach that combines a citation index with a synthetic article-quality measure. A citation index was constructed by analysing 6.6 billion links between Wikipedia pages, enabling the identification of the most influential articles in each language edition.
The scientific article of our Department’s employees entitled “Sentence Embeddings and Semantic Entity Extraction for Identification of Topics of Short Fact-Checked Claims” has been published in open access. The paper describes an approach to assigning topics to claims verified by fact-checking agencies.
During the international conference Wikimania 2024, a panel discussion entitled “Keynote: Opening the Academia” took place, in which Dr. Włodzimierz Lewoniewski participated. The panel concerned the topic of open science and its various aspects. In particular, the challenges faced by academic institutions that try to implement the principles of open science and the obstacles that hinder these processes were discussed. The role of Wikimedia projects, such as Wikipedia, in the … Read More
The work of our scientists on the analysis of digital currency exchanges has been published on the Springer website. As part of the research, models for predicting the success and bankruptcy of cryptocurrency exchanges were developed, based on financial data and information collected from open Internet sources such as Wikipedia and Wikidata. The aim of the work was to identify key aspects that can support the risk analysis process and … Read More
