# Dataset Card for Saga Corpus

<!-- START-SHORT DESCRIPTION -->
The Icelandic sagas
<!-- END-SHORT DESCRIPTION -->

The Saga Corpus contains 49 Old Icelandic narrative texts: 
- Family Sagas (Íslendingasögur, published by Svart á hvítu in 1985-1986), 
- Sturlunga Saga (published by Svart á hvítu in 1988), 
- Sagas of the Kings of Norway (Heimskringla, published by Mál og menning in 1991) 
- and the Book of Settlement (Landnámabók, published by Hið íslenzka fornritafélag in 1968). 
The spelling was normalized to Modern Icelandic spelling and some inflectional endings were changed to Modern Icelandic form. 

Most documents are individual sagas or þættir (tales). One document, Íslendinga þættir, is a single collection bundling many tales together.

## Dataset Structure
An example from the dataset looks as follows.

<!-- START-SAMPLE -->
```py
{
  "id": "saga_F01",
  "text": "Bandamanna saga - Konungsbók\n\nÚr: Íslendingasögur I\n\nÓfeigur hét maður. Hann bjó norður í Miðfirði á[...]",
  "source": "saga",
  "added": "2026-07-23",
  "created": "1100-01-01, 1400-01-01",
  "token_count": 21687
}
```

### 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](#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.

### Annotation Overview
<!-- START-ANNOTATION PLOTS -->
Each document comes with annotations describing its content, such as content quality, information density, and educational value.
Each bar shows the share of documents at each level of one annotation, from worst (light) to best (dark).
To learn more about the annotations and how to use them, see the [annotations section](https://huggingface.co/datasets/danish-foundation-models/icelandic-dynaword#annotations) of the main readme.

## Additional Information

### Limitations

The sagas are medieval texts, written down roughly in the 12th–14th century, but the
source records no per-text composition date. The `created` field spans the whole
range to reflect that uncertainty.

The spelling was normalized to Modern Icelandic spelling and some inflectional endings were changed to Modern Icelandic form.
