| Challenge: | Language models encode extensive factual knowledge within their parameters. |

Copied to clipboard
| Challenge: | Factual update is a task of inserting, replacing, or removing facts in large language models. |

| Outcome: | The proposed dataset compares the state of the Wikidata knowledge base at 4 January 2021 and 27 February 2023. |
