# SLDS monolingual subsets

Monolingual pairs from the Swiss Landmark Decisions Summarization dataset
([ipst/slds](https://huggingface.co/datasets/ipst/slds), Rolshoven et al., Findings of
EMNLP 2025). Each row pairs a Swiss Federal Supreme Court decision with the headnote the
court publishes in the same language.

## Construction

Each config keeps exactly the rows of the corresponding `ipst/slds` split where
`decision_language` and `headnote_language` both equal the config's language, with the
original column values unchanged (`decision_id`, `decision`, `headnote`, `law_area`,
`year`, `url`). The cross-lingual pairs of the source dataset are omitted.

## Subsets and splits

| config | train | validation | test |
|---|---|---|---|
| de | 13,550 | 137 | 207 |
| fr | 5,456 | 55 | 107 |
| it | 939 | 8 | 12 |
