The Chat-EUR-Lex dataset comprises a selection of legal acts in English and Italian sourced from EUR-Lex, covering the period from January 1, 2014, to December 31, 2023. Specifically, it includes all historical texts preserved in Celex 3 that remain unaltered over time, along with the most recent consolidated versions in Celex 0 for acts that have undergone amendments. Corrigenda are omitted from this dataset. Additionally, all the EUR-Lex entries that are not provided with XML or HTML data are excluded from the selection.\

The Chat-EUR-Lex project is funded by the European Union within the framework of the [NGI Search project](https://ngi-search-2nd-open-call.fundingbox.com/) under grant agreement No 101069364.
