BUT-LCC Corpus
BUT-LCC (Brno University of Technology Large Czech Collection) is a corpus of Czech texts. It was cleaned using exact deduplication, fuzzy deduplication (using minhashlsh), n-gram language model, and an SVM classifier that filters inappropriate content (we manually labelled).

| Part | GB of text | GB of titles | % |
|---|---|---|---|
| CulturaX | 157.79 | 3.85 | 49 |
| TenTen-cs-2017 | 48.97 | 0.95 | 15 |
| BUT_Crawl | 25.15 | 0.8 | 8 |

| idnes_comments | 7.38 | 0.03 | 2 |
| Sum | 319.36 | 8.84 |
Format
The corpus consists of train and test splits. It uses jsonl format, which means that every sample is JSON on its own line.
Sample Format
{
"id": unique identifier,
"part": original source,
"title": source document title,
"text": the context,
"ugly": (type: bool) inappropriate content,
"ugly_score": (type: float) score from SVM classifier that filters inappropriate content
