# Målfrid parallel 

This dataset contains parallel data for the following languages: Norwegian Bokmål, Norwegian Nynorsk, English. 

## Loading datasets
The dataset is organized by the three language pairs "nob_nno" (Norwegian Bokmål, Norwegian Nynorsk), "nob_eng" (Norwegian Bokmål, English) and "nno_eng" (Norwegian Nynorsk, English).  
Each division has a train, val, test split, and there is no overlap of source domains between the splits.

Load the dataset you want with the `name` arg like this: 
```python
from datasets import load_dataset

ds = load_dataset("NbAiLab/maalfrid_parallel", name="nno_eng")

```


## Source data 
The source data is from the Målfrid project, which involves scraping .no governmental web sites to report language use.  
We combined the following datasets:
- Målfrid 2021 [resource catalogue](https://www.nb.no/sprakbanken/ressurskatalog/oai-nb-no-sbr-69/)
- Målfrid 2022 [resource catalogue](https://www.nb.no/sprakbanken/ressurskatalog/oai-nb-no-sbr-97/)
- Målfrid 2023 [resource catalogue](https://www.nb.no/sprakbanken/ressurskatalog/oai-nb-no-sbr-98/)
- Målfrid 2024 [resource catalogue](https://www.nb.no/sprakbanken/ressurskatalog/oai-nb-no-sbr-99/)
- Målfrid 2025 [resource catalogue](https://www.nb.no/sprakbanken/ressurskatalog/oai-nb-no-sbr-102/)

## Alignment method
The document pairs were aligned per website with [NbAiLab/nb-sbert-v2-base](https://huggingface.co/NbAiLab/nb-sbert-v2-base) and the sentence-transformers library.  
For English-Norwegian parallel data, the minimun cosine similarity threshold is 0.80, and for Norwegian parallel data it is 0.95. See [source code](https://github.com/Sprakbanken/alignment_eksperimenter)
