| Few-NERD is a large-scale, fine-grained manually annotated named entity recognition dataset, | |
| which contains 8 coarse-grained types, 66 fine-grained types, 188,200 sentences, 491,711 entities | |
| and 4,601,223 tokens. Three benchmark tasks are built, one is supervised: Few-NERD (SUP) and the | |
| other two are few-shot: Few-NERD (INTRA) and Few-NERD (INTER). | |
