Danish Legal LM

This model is pre-training 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: 0.7302 (up to 128 tokens)
  • Loss: 0.7847 (up to 512 tokens)

Model description

This is a RoBERTa (Liu et al., 2019) 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.
