Legal-CamemBERT-base
Legal-CamemBERT-base is a CamemBERT-base model further pre-trained on 23,000+ statutory articles from the Belgian legislation.
Usage
from transformers import AutoTokenizer, AutoModel
tokenizer = AutoTokenizer.from_pretrained("maastrichtlawtech/legal-camembert-base")
model = AutoModel.from_pretrained("maastrichtlawtech/legal-camembert-base")
Training
Background
We utilize the camembert-base checkpoint and further pre-train it with a masked language modeling (MLM) objective on legislation in French using the script from Hugging Face.
Hyperparameters
We train the model on a single Tesla V100 GPU with 32GBs of memory during 200 epochs (i.e., ~50k steps) using a batch size of 32. We use the AdamW optimizer with an initial learning rate of 5e-05, weight decay of 0.01, learning rate warmup over the first 500 steps, and linear decay of the learning rate. The sequence length was limited to 512 tokens.
Data
We use the Belgian Statutory Article Retrieval Dataset (BSARD) to further pre-train the model. BSARD is a French native dataset for studying legal information retrieval, which consists of more than 22,600 statutory articles from Belgian law and about 1,100 legal questions posed by Belgian citizens and labeled by experienced jurists with relevant articles from the corpus.
