# Dataset Card for Czech SNLI
Czech translation of the [Stanford Natural Language Interface](https://nlp.stanford.edu/projects/snli/) (SNLI) dataset with manual annotation of a SNLI subset.
In addition to the entailment/contradiction/neutral inference, a "bad translation" class was added.
The annotation was done by students of NLP or computational linguistics. 1499 same pairs were annotated by two students to check IAA.
## Dataset Details
The annotation for Czech premise-hypothesis pairs is done on 165390 pairs from train, test, and dev parts of the SNLI in the following distribution:
- train: 159650
- dev: 2860
- test: 2880
The premise-hypothesis pairs were translated using the LINDAT Translation at https://lindat.mff.cuni.cz/services/translation/.
The CUBBITT model was published as:
Popel, M., Tomkova, M., Tomek, J. et al. Transforming machine translation: a deep learning system reaches news translation quality comparable to human professionals. Nat Commun 11, 4381 (2020). https://doi.org/10.1038/s41467-020-18073-9
## Annotation
From the 165390 pairs, 151470 (91.58%) were considered understandable (i.e., they were not marked as "bad translation" but the translation may not be accurate enough to preserve the entailment).
## Inter-Annotator Agreement
Two random annotators obtained the same dataset. The kappa score is 0.67 (substantial agreement).

## Dataset Formats
Dataset is available as TSV and JSONL.
The JSONL version only contains pairs that were *not* annotated as "bad translation".
In case of multiple annotations, only the *agreed* pairs (where both annotators agreed) are selected.
The JSONL contains 149660 sentence pairs. |
