+# Thai Image Captioning Dataset (Samples 10k)
+
+This dataset is a **Thai image captioning corpus** created to generate natural and human-like image captions in Thai. 
+It includes a curated subset of **10,000 samples** randomly selected from the original training data, providing a smaller yet representative dataset for efficient experimentation.
+
+---
+
+## Dataset Description
+
+The dataset comprises high-quality image captions in Thai, designed for training and evaluating image captioning models. It integrates image-caption pairs from two main sources:  
+1. **Microsoft COCO** – A publicly available dataset enriched with English captions.  
+2. **Nectec IPU24** – A proprietary collection of image-caption pairs curated by NECTEC (Thailand).
+
+The smaller version, provided here (`train-sample10k`), is derived from the original datasets, offering a compact and effective resource for research and development.
+

+
+## Data Source and Download
+
+- The full COCO 2017 dataset can be accessed and downloaded from the official website: [COCO Dataset](https://cocodataset.org/#download).  
+- The Nectec IPU24 dataset is available through NECTEC's official portal: [NECTEC Corpus](https://aiforthai.in.th/corpus.php).
