- **Tokenisation:** white-space separated, punctuation attached to tokens
as in standard text.
- **Script:** Latin alphabet; Cyrillic and heavy non-Bosnian segments are
strongly reduced during cleaning.
- **Size:**
- bytes: ~6,182,905,888

## 3. Provenance of the text
The corpus is derived from three publicly available resources hosted on
the CLARIN.SI repository:
1. **Sarajevo Corpus of SMS Messages in Bosnian 1.1**
2. **Bosnian web corpus bsWaC 1.1**
3. **Bosnian web corpus CLASSLA-web.bs 1.0**
All source corpora are cited in the accompanying papers and should be
cited separately by users of this dataset.

## 4. Cleaning and processing (short summary)
The following high-level steps were applied:
- Conversion of XML/vert/CONLLU formats to plain text (one sentence per line).
- Unicode normalisation (NFC), UTF-8 output.
- Removal of technical noise (URLs, boilerplate, CMS headers/footers,
file names, log fragments, etc.).
- Heuristic removal of lines with a high proportion of non-letter symbols.
- Language filtering to favour Bosnian (diacritics, function words).
- Genre classification into several super-genres using a TF–IDF +
logistic regression model trained on CLASSLA-web.bs genres.
- Additional *paper-grade* cleaning and optional deduplication.
Full details and references are provided in `bosnian_corpus_en.pdf`.
