| # CC3M-eu (Basque Translation) | |
| ## 📚 Overview | |
| **CC3M-eu** is a Basque version of the **Conceptual Captions 3M** dataset. It consists of approximately 3.3 million image-description pairs where the original English captions have been translated into Basque using the **mt-hitz-en/eu** specialized translation pipeline. | |
| **Important:** This is **not the official dataset**. It is an independent community translation effort designed to facilitate the training of Vision-Language Models (VLMs) and CLIP-style encoders for the Basque language. | |

| ## 📁 Dataset Schema | |
| The schema has been adapted to include both the source and the translated content: | |
| 1. **id**: Unique identifier for each sample. | |
| 2. **url**: The original source URL for the image. | |
| 3. **caption_en**: The original English description. | |
| 4. **caption_eu**: The generated Basque translation. | |
| ## 🔧 How We Built It | |
| 1. **Extraction**: English captions were pulled from the official CC3M TSV files. | |
| 2. **Translation**: Each caption was translated using the `mt-hitz-en/eu` model, which is specifically optimized for English-to-Basque scientific and general domain text. | |
| 3. **Cleanup**: Applied basic post-processing to handle HTML entities and formatting artifacts. | |
| *Note: No images were hosted or modified; only the textual metadata is provided.* | |
| ## 🚦 Limitations & Ethical Considerations | |
| - **Non-official**: This version has not been audited by Google; semantic drift may occur during translation. | |
| - **Link Stability**: Like the original CC3M, many image URLs may be dead or lead to 404 errors. | |
| - **Biases**: The dataset may inherit or amplify social biases present in the original English data or the NMT model. | |
| ## 💻 Quick Start | |
