# Dataset Card for *DTAK-transnormer-full* (v1.0)

## Dataset Details

### Dataset Description

*DTAK-transnormer-full* is a modified subset of the [*DTA-Kernkorpus*](hhttps://www.dwds.de/d/korpora/dtak) (*Deutsches Textarchiv*, German Text Archive Core Corpus).
It is a parallel corpus of German texts from the period between 1600 to 1899, that aligns sentences in historical spelling with their normalizations.
A normalization is a modified version of the original text that is adapted to modern spelling conventions.
This corpus can be used to train and evaluate models for normalizing historical German text. 

We also publish a more light-weight variant of this dataset that does not contain all annotation layers, but is otherwise identical: [*DTAK-transnormer-basic*](https://huggingface.co/datasets/ybracke/dtak-transnormer-basic-v1). 

Refer to [*DTAK-transnormer-basic*](https://huggingface.co/datasets/ybracke/dtak-transnormer-basic-v1) for all information about the dataset's content and creation. The only difference between the datasets is that this dataset contains additional properties based on the original text and the normalized text, see [Dataset Structure](#dataset-structure). 

*DTAK-transnormer-full* has been created and can be further modified with the project [transnormer-data](https://github.com/ybracke/transnormer-data). The dataset was created in the context of [Text+](https://text-plus.org/), for the development of the tool [Transnormer](https://github.com/ybracke/transnormer).

## Usage

Note that, unlike *DTAK-transnormer-basic*, this dataset cannot be directly loaded with `datasets.load_dataset`. That is also why the Dataset Viewer does not work properly. Refer to [transnormer-data](https://github.com/ybracke/transnormer-data) on how to load the data or use *DTAK-transnormer-basic* if you do not need the additional layers.

### Data Fields

See the description on the Dataset Card of [*DTAK-transnormer-basic*](https://huggingface.co/datasets/ybracke/dtak-transnormer-basic-v1) for the properties that occur in both variants. The following properties are only included in *DTAK-transnormer-full*:

- `orig_tok`: List[str], tokenized version of `orig`
- `norm_tok`: List[str], tokenized version of `norm`
- `orig_spans`: List[List[int]], index spans of the elements of `orig_tok` in `orig`, inner lists have length 2
- `norm_spans`: List[List[int]], index spans of the elements of `norm_tok` in `norm`, inner lists have length 2
- `alignment`: List[List[int|None]], alignment of the elements of `orig_tok` and `norm_tok`, inner lists have length 2
