Dataset Card for NBAiLab/nb_bert_debiased

The Norwegian Colossal Corpus is a collection of multiple smaller Norwegian corpuses suitable for training large language models. We have done extensive cleaning on the datasets, and have made them available in a common format. The total size of the NCC is currently 45GB.

How to Use

from datasets import load_dataset
data = load_dataset("NBAiLab/nb_bert_debiased", streaming=True)

Download Data

If you do not want to use the HuggingFace Dataset-library for training, or if you want to do additional pre-processing, it is also possible to download the files locally.

# Clone the training set
git clone https://huggingface.co/datasets/NbAiLab/nb_bert_debiased

# Create one large training file of all shards without unpacking
cat nb_bert_debiased/data/train*.gz > onefile.json.gz

List of all the files.

lang_fasttext	String. Language of text identified by FastText
lang_fasttext_conf	String. Confidence calculated by FastText
text	String. The complete utf-8 document. If longer than 1M characters it is split.

Dataset Creation

We are providing a train and a validation split. The standard size of the validation is a single 1GB file, while train is sharded in 1GB chunks. All files are gzipped.

Build date: 01042022

Initial Data Collection and Curation

The procedure for the dataset creation is described in detail in our paper.

abstract = "In this work, we show the process of building a large-scale training set from digital and digitized collections at a national library.
The resulting Bidirectional Encoder Representations from Transformers (BERT)-based language model for Norwegian outperforms multilingual BERT (mBERT) models
in several token and sequence classification tasks for both Norwegian Bokm{aa}l and Norwegian Nynorsk. Our model also improves the mBERT performance for other
languages present in the corpus such as English, Swedish, and Danish. For languages not included in the corpus, the weights degrade moderately while keeping strong multilingual properties. Therefore,
we show that building high-quality models within a memory institution using somewhat noisy optical character recognition (OCR) content is feasible, and we hope to pave the way for other memory institutions to follow.",
