## Dataset Description

This dataset contains 500 authentic Sinhala mixed-script sentences in which Unicode Sinhala and Romanized Sinhala scripts naturally co-occur within the same text. The sentences were collected from social media platforms, blogs and online forums, preserving real-world script-switching patterns without synthetic manipulation. The dataset is designed to support research on language model robustness, script mixing, and low-resource multilingual NLP, particularly under mixed-script conditions.


## Dataset Structure

The dataset contains a single text field:

`text`: A naturally occurring Sinhala mixed-script sentence containing both Unicode and Romanized scripts.

## Statistics

- Number of sentences: 500
- Mean sentence length: 9.49 ± 4.03 tokens
- Vocabulary size: 2,262 unique tokens

## How to Use the Dataset

You can load the dataset using the Hugging Face datasets library:

```python
from datasets import load_dataset

dataset = load_dataset("Minuri/sinhala-mixedscript")
example = dataset["data"][0]
print(example["text"])
