# Dataset Overview
From our experience, **OPEN-SOURCE DATASETS AND MODELS FROM THE GLOBAL COMMUNITY HAVE HELPED US GREATLY**. 
However, we also learned that **TO PUSH THE MODELS FURTHER, WE NEED MORE HIGH-QUALITY LOCAL DATA** to **DEVELOP STRONGER VIETNAMESE AI MODELS 💪**.


This dataset consists of **23,403** Vietnamese 🇻🇳 handwritten text images collected and curated for **Handwritten Text Recognition** research and applications.

The original images were **crawled from public internet sources**. For each image, **only one bounding box** containing handwritten text was selected. All samples were then <span style="color:red"><b>manually annotated by human labelers</b></span>, ensuring both **high diversity** and **high transcription accuracy**. 

We are actively scaling to hundreds of thousands of **HUMAN-VERIFIED** samples using the same rigorous annotation process.


## Dataset Structure

The dataset is released with two splits:

- **Train**: 22,403 samples
- **Test**: 1,000 samples
