Model description

This model pre-train the model Jean-Baptiste/camembert-ner on a set of ~845k entries from Paris trade directories from the XIXth century extracted with OCR. Trade directory entries are short and strongly structured texts that giving the name, activity and location of a person or business, e.g:

Peynaud, R. de la Vieille Bouclerie, 18. Richard, Joullain et comp., (commission- —Phéâtre Français. naire, (entrepôt), au port de la Rapée-

Intended uses & limitations

This model is intended for reproducibility of the NER evaluation published in the DAS2022 paper. Several derived models trained for NER on trade directories are available on HuggingFace, each trained on a different dataset :

• das22-10-camembert_pretrained_finetuned_ref: trained for NER on ~6000 directory entries manually corrected.
• das22-10-camembert_pretrained_finetuned_pero: trained for NER on ~6000 directory entries extracted with PERO-OCR.
• das22-10-camembert_pretrained_finetuned_tess: trained for NER on ~6000 directory entries extracted with Tesseract.
