Reasoning Before Translation: Enhancing Legal Machine Translation with Structured Reasoning

Aixiu An, Michael Jungo, Eloi Eynard, Mark Drenhaus, Andreas Fischer, Jean Hennebert, et al.

Neural machine translation (NMT) in the legal domain is a linguistically and conceptually demanding task, primarily due to the complexity of legal language and the high level of precision it requires. The recent emergence of reasoning-capable language models opens new possibiliti…

Evaluating Chunking Strategies for Retrieval-Augmented Generation on Academic Texts

Valentin J. J. Kreileder, Johannes Reisinger, Andreas Fischer

Retrieval-Augmented Generation (RAG) systems use the question-answering capabilities of Large Language Models (LLMs) to access information outside their parameters. We evaluate if cluster-based semantic chunking improves retrieval and answer quality compared to fixed-size and rec…

Operationalizing Instability in Rule-Based Complete Blood Count Phenotyping Using Uncertainty-Aware Machine Learning

Karim Shater, Catharina Gerhards, Osman Evliyaoglu, Stefanie Nittka, Andreas Fischer

Background: Complete blood count (CBC) phenotypes are routinely assigned using deterministic rule-based thresholds. While operationally efficient, such rules may lead to unstable phenotype assignments for results close to clinical cutoffs in the presence of analytical variability…
