# Romanian Sentences (BlackKakapo/ro-sentences)
A large-scale corpus of Romanian sentences, created by processing and splitting public text datasets into sentence-level units.
The main purpose of this dataset is to support **Masked Language Modeling (MLM)**, **continual pretraining**, **semantic textual similarity (STS)**, and other NLP tasks in Romanian.

## 📚 Data Sources
This corpus was built from the following datasets:
- [`statmt/cc100`](https://huggingface.co/datasets/statmt/cc100) – large-scale web crawl.
- [`wikimedia/wikipedia`](https://huggingface.co/datasets/wikimedia/wikipedia) – Romanian Wikipedia articles.
- [`dumitrescustefan/diacritic`](https://huggingface.co/datasets/dumitrescustefan/diacritic) – cleaned and re-diacritized Romanian text.
- [`agentlans/multilingual-sentences`](https://huggingface.co/datasets/agentlans/multilingual-sentences) – multilingual sentences including Romanian subsets.
### Processing
- All text was **split into sentences** using simple segmentation rules.
- Only **clean sentences** were kept, with normalized Unicode characters.
- Very short sentences (e.g. one word) were removed.
- Whitespace and separators were standardized.
