A system developed by our researcher secured second place in the international SemEval-2026 competition focused on narrative similarity. Its developer, Marcin Sawiński, presented his research at ACL 2026 in San Diego, United States, one of the world’s leading international conferences on natural language processing.
At the ACL 2026 conference in San Diego, USA, researchers from our Department presented their paper entitled “PUEB-DimASR at SemEval-2026 Task 3: Escaping the Mean Regression Trap with Graph-Enhanced Transformers for Dimensional Aspect-Based Sentiment Regression“, prepared as part of the SemEval-2026 workshop. The paper was authored by Oskar Riewe-Perła and Prof. Agata Filipowska.
During the international ACL 2026 conference in San Diego, USA, Ewelina Księżniak presented research findings on reducing content bias in syllogistic reasoning by large language models. Her poster was based on the paper entitled “Team ewelinaksiez at SemEval-2026 Task 11: Reducing Content Bias in Syllogistic Reasoning via Semantic Abstraction”.
At the invitation of Arizona State University, Dr. Włodzimierz Lewoniewski delivered a talk entitled “Methods and Tools for Automatic Quality Assessment of Wikipedia Articles and Their Information Sources”. The talk focused on the challenges associated with the automatic assessment of information quality in multilingual Wikipedia.
An open-access paper by researchers from our Department entitled “Evaluating Multilingual Sentiment Classifiers Using an LLM-Annotated Wikipedia Benchmark” has been published. Authors of the work: Dr. Milena Stróżyna, Dr. Włodzimierz Lewoniewski, Izabela Czumałowska. The paper was presented at ACL 2026 in San Diego, held from July 2 to 7, 2026.
