"Assessing the State of the Art in Scene Segmentation" accepted at NAACL 25

Our paper "Assessing the State of the Art in Scene Segmentation" has been accepted at the 2025 Annual Conference of the Nations of the Americas Chapter of the ACL. In our paper, we assess the state of the art for scene segmentation for german novels and compare BERT-based to current Llama models.

"Modeling and Analyzing the Influence of Non-Item Pages on Sequential Next-Item Prediction" accepted at TORS Journal

Our paper "Modeling and Analyzing the Influence of Non-Item Pages on Sequential Next-Item Prediction" just got accepted at the ACM Journal "Transactions on Recommender System". In our work, we introduce and analyze the utility of non-item interactions for sequential recommender systems.
