The paper reports that in English all‑words word sense disambiguation (WSD), the scarcity of high‑quality labels—not the models—has become the limiting factor. The authors introduce lexEN, a human‑adjudicated correction layer over the Maru2022 ALL_NEW benchmark, and SenseBench, a living leaderboard for LLM WSD evaluation. They show that frontier large language models reach about 95 % accuracy on lexEN‑v1, that relabeling corpora with these models improves downstream systems, and that fine‑grained WordNet senses are often ill‑posed, with coarsening improving both annotator agreement and model performance.
"whyItMatters":"The study highlights that improving label quality and managing annotation costs are now the critical challenges for advancing WSD performance, as model accuracy is already near its theoretical ceiling."

The study evaluates whether a single confidence threshold in typed decision interfaces treats all languages equally. Using 1,000 items in 51 languages across three vendors, it finds that English consistently achieves higher coverage—clearing the 0.9 threshold 8.6–11.7 percentage points more often than other languages—despite similar accuracy. Even when thresholds are re‑weighted or calibrated per language, the gap persists, and translating inputs into English reduces but does not eliminate it. The authors recommend reporting per‑language coverage at the operating threshold.

Zuse is a family of decision models (4B, 9B, and 27B) that predict probabilities for a fixed set of options across 27 European languages by training a low‑rank adapter and a pointer head on frozen open‑weight bases. The 27B model achieves 87.5 % accuracy on a broad European test suite of 11 sources, 9 task groups, and 27 languages, with a pooled expected calibration error of 0.016. Post‑hoc analysis reveals that miscalibration is task‑dependent, that automated decision share aligns more with chance‑corrected skill than raw accuracy, and that performance on languages outside the base model’s documented list is consistently lower.
