# Bosnian Corpus (v1.0) |
This package contains the plain-text **Bosnian Corpus (v1.0)** and the |
accompanying documentation papers. |
- **DOI:** https://doi.org/10.5281/zenodo.17757098 |
- **Author:** Hasan Kahrimanović |
- **Release date:** 2025-11-29 |
The corpus is built specifically for quantitative studies of Bosnian |
(language entropy, “language energy”) and for general NLP experiments. |

## 1. Contents of this package |
The main files in this archive are: |
- `bosnian_corpus.txt` |
Plain-text Bosnian corpus (approx. 6.03 GB). |
One sentence per line, cleaned and deduplicated. |
- `bosnian_corpus_en.pdf` |
English description of the corpus construction and preprocessing pipeline. |
- `bosanski_korpus_bs.pdf` |
Bosnian-language description of the same corpus. |
Optional (only if included): |
- `bosnian_corpus_*.txt` |
Genre-specific subsets (NEWS, OPINION, FORUM_CHAT, INFO_HOWTO, |
LEGAL_ADMIN, LITERATURE, ADS_PROMO, MIX_OTHER). |
--- |
## 2. Data format |
- **Encoding:** UTF-8, Unicode NFC. |
- **Line structure:** one sentence or short message per line. |
- **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 |
- tokens: 942,515,845 |
- types (vocabulary): 4,463,058 |
For detailed statistics and cleaning steps, see the PDFs in this package. |

## 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`. |

Bosnian Corpus v1.0 (cleaned)
This dataset provides a cleaned and genre-annotated corpus of contemporary Bosnian, designed for quantitative linguistic analysis, information-theoretic research, entropy estimation, corpus linguistics, language modeling, and modern NLP tasks.
The canonical release of the corpus is archived on Zenodo:
Dataset DOI:
https://doi.org/10.5281/zenodo.17757098
Corpus composition
The corpus is constructed from three publicly available language resources distributed through the CLARIN.SI repository:
- Sarajevo Corpus of SMS Messages in Bosnian 1.1
- Bosnian Web Corpus bsWaC 1.1
- Bosnian Web Corpus CLASSLA-web.bs 1.0
The source material was converted to plain text, cleaned, normalized, partially deduplicated, and organized into a consistent corpus suitable for large-scale quantitative analysis.
Original source resources retain their respective attribution and licensing requirements.
Size and statistics
- Total size: approximately 6.18 GB (6,182,905,888 bytes)
- Lines: 46,258,935
- Tokens: approximately 942,515,845
- Language: Bosnian
- Encoding: UTF-8
Genre structure
The web-derived portion of the corpus is organized into the following high-level genre categories:
- News
- Opinion
- Forum / Chat
- Info / HowTo
- Legal / Administrative
- Literature
- Ads / Promo
- Mix / Other
Separate text files are provided for the genre categories, together with a global corpus file combining the available material.
The global corpus is intended primarily for large-scale statistical analysis, entropy estimation, language modeling, and related NLP experiments.
Cleaning and normalization
The preprocessing pipeline focuses on reducing technical and non-linguistic noise while preserving the linguistic signal required for quantitative analysis.
Processing includes:
- UTF-8 and Unicode NFC normalization
- correction of common mojibake artifacts
- removal of URLs and e-mail addresses
- removal of file names, technical boilerplate, and CMS/navigation content
- filtering of lines dominated by non-linguistic characters
- partial deduplication
- optional digit normalization and lowercasing
- language filtering to retain primarily Bosnian-language material
The complete preprocessing methodology and implementation are documented in the associated code repository.
