## Summary
Earlier NLP studies concluded that pretrained transformers largely ignore negation, based on context-free minimal pairs such as "Birds can/cannot fly." Drawing on the pragmatic tradition in linguistics, Gubelmann and Handschuh argue that such probes confuse two failures: not grasping negation, and not inferring a default context in which a negated sentence would make sense. To separate them, they build masked language modelling tasks in which a short micro-context precedes the masked slot. The test is whether a model avoids predicting a verb that the preceding sentence negated. The templates are designed so that known shallow cues do not help, and the data are tailored to each tested model. Factors such as gender, first name, profession, syntax, model-specific probability rank, misleading primes and shifts in reference are varied systematically. Fine-tuned variants of the strongest models are also evaluated. Almost all models proved sensitive to negation, and fine-tuned RoBERTa-large performed robustly. The authors therefore paint a considerably more optimistic picture of PLMs' negation understanding than earlier semantics-based work. They also stress that context must be controlled when probing models.

## Key points
- The resource consists of 43 hand-crafted templates, each checked together with Dr. David Dolby, who is both a native speaker and a language philosopher. Expanded per model, they yield roughly 12 million test sentences.
- Tested families include BERT (base/large cased), RoBERTa, XLNet and DistilBERT, plus fine-tuned "neg-" variants of the best models.
- For neg-roberta-large, the tendency to repeat an activity verb fell by about 44% when that verb was negated in the context.
- Under misleading primes, neg-roberta-large's error rate stayed at or below 12%, rising to 30% only when a random sentence was inserted. Over the same insertions, neg-xlnet-large's error rate climbed from 8% to 43% and beyond.
- The context-specific probability rank of a token strongly affects errors, especially for BERT, with most of the drop occurring between ranks 0 and 50. When the subject clearly changes, the RoBERTa models and fine-tuned XLNet repeat the verb with more than 85% probability, showing that they track reference.
