+# Dataset Card for LAION-COYO-CC (URL + Caption)
+
+This dataset provides a lightweight, web-scale resource of image-caption pairs in the form of URLs and their associated textual descriptions (captions). It is designed for training and evaluating vision-language models where users retrieve images independently from the provided links.
+
+This dataset card is based on the [Hugging Face dataset card template](https://github.com/huggingface/huggingface_hub/blob/main/src/huggingface_hub/templates/datasetcard_template.md?plain=1).
+
+---
+
+## Dataset Details
+
+### Dataset Description
+
+This dataset merges subsets from three well-known large-scale image-text datasets:
+
+- **LAION-400M** (10% sample): A multilingual dataset of image-text pairs crawled from the web and filtered with CLIP.
+- **COYO-700M** (10% sample): A large-scale Korean-English image-text dataset from Kakao Brain.
+- **Conceptual Captions**: A publicly available dataset from Google AI with filtered image captions from the web.
+
+The dataset consists of three splits:
+
+| Split                | Source                 | # Examples     |
+|----------------------|------------------------|----------------|
+| `laion`              | LAION-400M (10%)       | 40,000,000     |
+| `coyo`               | COYO-700M (10%)        | 70,000,000     |
+| `conceptualCaptions` | Conceptual Captions    | 3,318,333      |
+
+All splits share the same two fields:
+- `url`: A direct link to the image.
+- `caption`: A natural language description of the image.
+
+- **Curated by:** [kamruzzaman-asif]
+- **Funded by [optional]:** N/A
+- **Shared by [optional]:** Hugging Face user: `kamruzzaman-asif`
+- **Language(s) (NLP):** Multilingual (primarily English, some Korean in COYO)
+- **License:** See individual source licenses (LAION and COYO are CC BY 4.0)

+
+## Uses
+
+### Direct Use
+
+This dataset is intended for:
+- Training or evaluating vision-language models (e.g., CLIP, BLIP, Flamingo)
+- Image-text retrieval tasks
+- Weakly supervised or semi-supervised learning with large-scale web data
+
+### Out-of-Scope Use
+
+- The dataset does not contain actual images — only URLs. Any tasks requiring image pixel data require separate downloading.
+- May contain broken or unreachable URLs.
+- Not suitable for tasks requiring curated or verified image-caption quality.
+
+---
+
+## Dataset Structure
+
+Each split is a flat table with the following fields:
+
+| Field     | Type    | Description                             |
+|-----------|---------|-----------------------------------------|
+| `url`     | string  | Publicly available link to an image     |
+| `caption` | string  | Textual description of the corresponding image |
+
+Data splits:
+- `laion`: Sampled from LAION-400M
+- `coyo`: Sampled from COYO-700M
+- `conceptualCaptions`: Full Conceptual Captions dataset
+

+
+## Dataset Creation
+
+### Curation Rationale
+
+Large-scale image-text datasets are essential for training multimodal models, but full datasets are often too large or difficult to host. This merged dataset offers a lighter, URL-only version to ease access and experimentation.
+
+### Source Data
+
+#### Data Collection and Processing
+
+- LAION and COYO subsets were sampled at approximately 10% of their full size.
+- Duplicates and malformed records were removed.
+- Only `url` and `caption` fields were retained.
+- Conceptual Captions was included in full.
+
+#### Who are the source data producers?
+
+The data originates from large web-scale crawls performed by the LAION team, Kakao Brain, and Google AI.
+
+---
+
+### Annotations
+
+No additional annotations beyond the original captions are included.
+
+#### Personal and Sensitive Information
+
+The dataset may contain content from the open web that includes personal, copyrighted, or sensitive material. Use responsibly and adhere to the terms of the original datasets.
+
+---
+
+## Bias, Risks, and Limitations
+
+- The data reflects web-scale distribution, which may contain biases, offensive content, or culturally insensitive material.
+- Captions are not manually verified.
+- URLs may expire or be removed over time.
+
+### Recommendations
+
+Researchers and developers should pre-filter, verify, and clean the dataset further for production or sensitive use cases.
