## Dataset Description
- **Homepage:** https://github.com/HITsz-TMG/Hansel
- **Paper:** https://arxiv.org/abs/2207.13005
Hansel is a high‑quality human‑annotated Chinese entity linking (EL) dataset, focusing on tail entities and emerging entities:
- The test set contains Few‑shot (FS) and zero‑shot (ZS) slices, has 10K examples and uses Wikidata as the corresponding knowledge base.
- The training and validation sets are from Wikipedia hyperlinks, useful for large‑scale pretraining of Chinese EL systems.
Please see our [WSDM 2023](https://www.wsdm-conference.org/2023/) paper **"Hansel: A Chinese Few‑Shot and Zero‑Shot Entity Linking Benchmark"** to learn more about our dataset.
For models in the paper and our processed knowledge base, please see our [Github repository](https://github.com/HITsz-TMG/Hansel).
