Eosc/NorBERT3 corpus

Workflow

• Cleaning
• Deduplication (MurMurHash)
• ...or another package

Sampling experiment

We plan to create two versions of the training corpus:

• baseline (as is)
• Wikipedia+NCC+NAK multiplied by two to match the C4 size (oversampling quality data)

Vocabulary

Starting with 50K, following NorBERT-2. May be later experiment with other values.

To Decide

The size of NBDigital is 662M tokens. Should we use it? It probably overlaps a lot with NCC.

How should we split training corpora: one sentence per line, one paragraph per line, one document per line?

A: BERT assumes that there is one sentence per line.
