# Danish LegalBERT (derivative of Maltehb/danish-bert-botxo)
This model is a derivative of [Maltehb/danish-bert-botxo](https://huggingface.co/Maltehb/danish-bert-botxo) adapted to legal text. It has been pre-trained on a combination of the Danish part of the MultiEURLEX (Chalkidis et al., 2021) dataset comprising EU legislation and two subsets (`retsinformationdk`, `retspraksis`) of the Danish Gigaword Corpus (Derczynski et al., 2021) comprising legal proceedings.
It achieves the following results on the evaluation set:
- Loss: -
## Model description
This is a BERT model (Devlin et al., 2018) model pre-trained on Danish legal corpora. It follows a base configuration with 12 Transformer layers, each one with 768 hidden units and 12 attention heads.
## Intended uses & limitations
