+# AI4SDG-BERT Model Card
+
+## Model Overview
+AI4SDG-BERT is a fine-tuned BERT model for detecting disaster-related content in tweets. It supports real-time monitoring of social media data to identify and classify potential urban disasters. This model contributes to Sustainable Development Goal 11 (Sustainable Cities and Communities) by facilitating early warning and emergency response systems.
+
+## Intended Use
+This model is intended for:
+- Disaster detection from Twitter or other social platforms
+- Urban emergency alert systems
+- Smart city infrastructure monitoring
+- Use by NGOs, civil defense units, or emergency data pipelines
+
+## Model Architecture
+- Base model: `bert-base-uncased`
+- Fine-tuned on: Disaster tweet classification dataset
+- Framework: Hugging Face Transformers + PyTorch
+
+## Training Dataset
+- Class distribution: 43% disaster, 57% non-disaster
+- Preprocessing: Lowercase, punctuation/emoji removal, URL stripping
+
+## Evaluation
+Evaluated on held-out test set from the dataset:
+- Accuracy: 92%
+- F1-score: 91%
+- AUC: 94%
+
+## Limitations
+- English-only model
+- May not generalize well to sarcasm, spam, or very informal text
+- Lacks direct geolocation unless paired with NER/metadata
+- Relies on Twitter API access for live inference
+
+## Ethical Considerations
+- May reflect bias in who reports disasters and how
+- Not intended as a sole source for life-critical decision making
+- Requires moderation to avoid misinformation risks
+
+## Example Usage
+```python
+from transformers import pipeline
+classifier = pipeline("text-classification", model="elam2909/bert-disaster-classifier")
+classifier("Huge earthquake just hit southern Turkey. Buildings are collapsing!")
+```
