Dataset Description

  • Number of samples: 300
  • Number of tokens (Llama 3): 1.03M
  • Average document length in tokens (min, max): 3.43K (13, 180.71K)

Dataset Summary

The Danish dynaword is a collection of Danish free-form text datasets from various domains. All of the datasets in Danish Dynaword are openly licensed and deemed permissible for training large language models.

Danish Dynaword is continually developed, which means that the dataset will actively be updated as new datasets become available. If you would like to contribute a dataset see the contribute section.

Loading the dataset

from datasets import load_dataset

name = "danish-foundation-models/danish-dynaword"
ds = load_dataset(name, split = "train")
sample = ds[1] # see "Data Instances" below

or load it by streaming the data

ds = load_dataset(name, split = "train", streaming=True)
dataset_iter = iter(ds)
sample = next(iter(dataset_iter))

You can also load a single subset at a time:

ds = load_dataset(name, "adl", split = "train")

To allow filtering we additionally provide extensive annotations available through the meta config:

meta = load_dataset(name, "meta", split = "train")

For more on how to use the annotations see the annotations section.

As Danish Dynaword is continually expanding and curated you can make sure that you get the same dataset every time by specifying the revision: You can also load a single subset at a time:

ds = load_dataset(name, revision="{desired revision}")

Languages

This dataset includes the following languages:

  • Danish (dan-Latn) as we as the dialects Bornholmsk (dan-Latn-bornholm) and Synderjysk (dan-Latn-synnejyl)

In addition it likely contains small amounts of English due to code-switching and Norwegian due to the historical relation between the two languages and language misclassificaitons due to their similarity.

Language is denoted using BCP-47, using the langauge code ISO 639-3 and the script code ISO 15924. The third element denote the region variant.

Domains

This dynaword consist of data from various domains (e.g., legal, books, social media). The following table and figure give an overview of the relative distributions of these domains. To see a full overview of the source check out the source data section

Dataset Structure

The dataset contains text from different sources which are thoroughly defined in Source Data.

Data Instances

Each entry in the dataset consists of a single text with associated metadata

{
  "id": "wiki_2",
  "text": "Arkæologi\nArkæologi er studiet af tidligere tiders menneskelige aktivitet, primært gennem studiet af[...]",
  "source": "wiki",
  "added": "2025-08-18",
  "created": "2024-06-16, 2024-06-16",
  "token_count": 3380
}

Data Fields

An entry in the dataset consists of the following fields:

  • id (str): A unique identifier for each document.
  • text (str): The content of the document.
  • source (str): The source of the document (see Source Data).
  • added (str): The date when the document was added to this collection.
  • created (str): The date range when the document was originally created.
  • token_count (int): The number of tokens in the sample computed using the Llama 3 tokenizer.

Data Splits

The entire corpus is provided in the train split.

Dataset Creation

Curation Rationale

These datasets were collected and curated with the intention of making openly license Danish data available. While this was collected with the intention of developing language models it is likely to have multiple other uses such as examining language development and differences across domains.

Annotations

Synthetic metadata is stored as data/{dataset}/metadata.parquet. These annotations were generated with ellamind/propella-1-4b and include fields for content type, quality, safety, audience level, educational level, PII presence, regional relevance and more.

The metadata rows include dataset and id, so a subset can be filtered and joined with the corpus rows:

from datasets import load_dataset

name = "danish-foundation-models/danish-dynaword"
texts = load_dataset(name, "adl", split="train")
meta = load_dataset(name, "meta", split="train").filter(
    lambda row: row["dataset"] == "adl"
)

texts_df = texts.to_pandas()
meta_df = meta.to_pandas()
adl_with_meta = texts_df.merge(meta_df, on="id", how="left")

Data Collection and Processing

Danish Dynaword is continually developed, which means that the dataset will actively be updated as new datasets become available. This means that the size of Dynaword increases over time as seen in the following plot:

The data collection and processing varies depending on the dataset and is documentationed the individual datasheets, which is linked in the above table. If possible the collection is documented both in the datasheet and in the reproducible script (data/{dataset}/create.py).

In addition to data specific processing we also run a series automated quality checks to ensure formatting (e.g. ensuring correctly formatted columns and unique IDs), quality checks (e.g. duplicate and empty string detection) and datasheet documentation checks. These checks are there to ensure a high quality of documentation and a minimal level of quality. To allow for the development of novel cleaning methodologies we do not provide more extensive cleaning.

Dataset Statistics

The following plot(s) are intended to give an overview of docuements length in the various sources.

License information

The license for each constituent dataset is supplied in the Source data table. This license is applied to the constituent data, i.e., the text. The collection of datasets (metadata, quality control, etc.) is licensed under CC-0.

Personal and Sensitive Information

As far as we are aware the dataset does not contain information identifying sexual orientation, political beliefs, religion, or health connected with utterer ID. In case that such information is present in the data we have been removed utterer information from social media content.

Bias, Risks, and Limitations

Certain works in this collection are historical works and thus reflect the linguistic, cultural, and ideological norms of their time. As such, it includes perspectives, assumptions, and biases characteristic of the period. For instance, the works of N.F.S. Grundtvig (grundtvig) were known to nationalistic views and critical stances toward specific groups, such as Germans, which may be considered offensive or exclusionary by contemporary standards.
