RoBERTa Span Detection

This model is a fine-tuned model of roberta-large after being trained on a mixture of NER datasets.

Basically, this model can detect NER spans (with no differenciation on classes). Labels use the IBO format and are:

  • 'B-TAG': beginning token of span
  • 'I-TAG': inside token of span
  • 'O': token not a span


This model has been trained in an efficient way and thus cannot be load directly from HuggingFace's hub. To use that model, please follow instructions on this repo.
