Earlier studies repurposed supervised corpora such as CoNLL'03, WNUT'17 and OntoNotes, which have only 4–18 coarse types and were evaluated under inconsistent settings. Real unseen entities, by contrast, tend to be fine-grained. To fill… 2. **[Prompt-learning for Fine-grained Entity Typing](https://md.research.elamur.ai/free/en/papers/ding-2022-prompt-learning-fine-grained-entity/)** *(2022 · 180 citations)* The paper asks whether prompt-learning, which recasts a downstream task as a cloze-style masked-word prediction, can replace classifier-based fine-tuning for fine-grained entity typing. It focuses on cases with little or no labelled data.
