Overview

Hansel is a high-quality human-annotated Chinese entity linking (EL) dataset, aimed at testing Chinese EL systems' generalization ability to 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.

Dataset

The data is available here. You can also download and use Hansel through the HuggingFace's datasets library 🤗.

The knowledge base (i.e., Wikidata) we use in our experiments is available here.
