Dataset Card for NbAiLab/NCC

---

⚠️ Important Update (December 2024)

Previously, newspapers were a significant part of the Norwegian Colossal Corpus (NCC), particularly the newspapers distributed under the so called "Språkbank-avtalen". As of December 2024, at the request of media houses, we have ceased distributing newspapers under this agreement, including the "Norsk Aviskorpus." However, NCC still includes numerous newspapers that are released under more open agreements.

---

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 30GB. The cleaning of the dataset is optimised for encoder models. If you are building a decoder model, it is usually advised to be a bit stricter on the cleaning procedure. We have included meta-data like source, publication year and languaguage confidence to aid this cleaning.

Dataset Summary

The NCC dataset contains json lines with language training data. Here is an example json line:

{
"id": "1006205",
"doc_type": "cc100",
"publish_year": 2021,
"lang_fasttext": "nn",
"lang_fasttext_conf": "0.641",
"text": "Eg har ein PLAN! KOS deg og ha ei fin helg"
}

Data Fields

id:	String with id to source of line and a unique identifier
doc_type	String describing type of media text extracted from (I.e. book,newspaper etc)
publish_year	Integer. The year text published. When year is undetermined it is set to 2021.
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 650Mb file, while train is sharded in 650Mb chunks.

Build date original corpus: 21012022 Build data revised corpus: 10032025

Initial Data Collection and Curation

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

  abstract  = {Norwegian has been one of many languages lacking sufficient available text to train quality language models. In an attempt to bridge this gap, we introduce the Norwegian Colossal Corpus (NCC), which comprises 49GB of clean Norwegian textual data containing over 7B words. The NCC is composed of different and varied sources, ranging from books and newspapers to government documents and public reports, showcasing the various uses of the Norwegian language in society. The corpus contains mainly Norwegian Bokmål and Norwegian Nynorsk. Each document in the corpus is tagged with metadata that enables the creation of sub-corpora for specific needs. Its structure makes it easy to combine with large web archives that for licensing reasons could not be distributed together with the NCC. By releasing this corpus openly to the public, we hope to foster the creation of both better Norwegian language models and multilingual language models with support for Norwegian.},

  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 Bokmål 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.},
