bart-base-spelling-nl

This model is a Dutch fine-tuned version of facebook/bart-base.

It achieves the following results on an external evaluation set:

CER - 0.025 WER - 0.090 BLEU - 0.837 METEOR - 0.932

Model description

This is a fine-tuned version of facebook/bart-base trained on spelling correction. It leans on the excellent work by Oliver Guhr (github, huggingface). Training was performed on an AWS EC2 instance (g5.xlarge) on a single GPU, and took about two days.

Intended uses & limitations

The intended use for this model is to be a component of the Valkuil.net context-sensitive spelling checker.

Training and evaluation data

The model was trained on a Dutch dataset composed of 6,351,203 lines of text from three public Dutch sources, downloaded from the Opus corpus:

nl-europarlv7.txt (2,387,000 lines)
nl-opensubtitles2016.3m.txt (3,000,000 lines)
nl-wikipedia.txt (964,203 lines)
