Hansel: A Chinese Few-Shot and Zero-Shot Entity Linking Benchmark

This is the main page of our WSDM 2023 paper Hansel.

************************************* Updates *************************************

  • 19/12/2022: We release the training and validation data of Hansel.
  • 27/07/2022: We release the test set of Hansel, consisting of Hansel-FS and Hansel-ZS. More training data, knowledge base and baselines are to come!

Contents

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 🤗.
