+This model is a fine-tuned version of [microsoft/deberta-v3-small](https://huggingface.co/microsoft/deberta-v3-small) on the Natural Questions dataset. It classifies question-context pairs into three categories: **No Answer**, **Has Answer**, or **Yes/No**, achieving 85.42% accuracy and 82.34% macro F1 score.
 
 ## Model Details
 
 ### Model Description
 
-This model performs **question-answering classification** by analyzing a question-context pair and predicting one of three outcomes:
+<!-- Provide a longer summary of what this model is. -->
 
-- 🔴 **Label 0 - No Answer**: The provided context does not contain sufficient information to answer the question
-- 🟢 **Label 1 - Has Answer**: The context contains a specific answer (either short span or longer passage)
-- 🔵 **Label 2 - Yes/No**: The question requires a binary YES or NO response
+This is a DeBERTa-v3-Small model fine-tuned for question-answering classification. Given a question and context, it predicts whether:
+- 🔴 **No Answer** (Label 0): The context doesn't contain an answer
+- 🟢 **Has Answer** (Label 1): The context contains a specific answer
+- 🔵 **Yes/No** (Label 2): The question requires a YES/NO response
 
-The model was developed as part of the **TensorFlow 2.0 Question Answering** Kaggle competition and represents a practical approach to pre-filtering question-answering systems in production environments.

 ## Uses
 
+<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
+
 ### Direct Use
 
-The model can be directly used for:
+<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
 
-1. **Question Answering System Pre-filtering**: Filter out unanswerable questions before expensive span extraction
-2. **Search Result Classification**: Determine if search results contain answers to user queries
-3. **Customer Support Routing**: Route questions based on whether knowledge base contains answers
-4. **Educational Assessment**: Classify whether reading passages can answer comprehension questions
-5. **Information Retrieval**: Evaluate document relevance for question-answering tasks
+The model can be used directly for:
+- **Question Answering System Pre-filtering**: Filter out unanswerable questions before expensive processing
+- **Search Result Classification**: Determine if search results contain relevant answers
+- **Customer Support Routing**: Route questions based on answer availability

 ### Downstream Use
 
-This model serves as an excellent foundation for:
+<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->
 
-- **Multi-stage QA Pipelines**: Use as first stage before extractive or generative QA models
-- **Hybrid QA Systems**: Combine with span extraction models for end-to-end question answering
-- **Dialog Systems**: Determine if chatbot has sufficient context to answer user queries
-- **Domain Adaptation**: Fine-tune further on domain-specific question-answering datasets
-- **Active Learning**: Prioritize annotation of examples where model is uncertain
+The model serves as a foundation for:
+- **Multi-stage QA Pipelines**: First stage before extractive/generative QA models
+- **Hybrid QA Systems**: Combine with span extraction for end-to-end QA
+- **Dialog Systems**: Determine if chatbot has sufficient context
+- **Domain Adaptation**: Fine-tune on domain-specific datasets
 
 ### Out-of-Scope Use
 
-The model is **not suitable** for:
+<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->
 
-- ❌ **Extractive Answer Span Prediction**: This model only classifies, it doesn't extract specific answer text
-- ❌ **Generative Question Answering**: Cannot generate free-form answers to questions
-- ❌ **Non-English Languages**: Trained exclusively on English text
-- ❌ **Long-Form Context**: Limited to 256 tokens; very long documents require truncation
-- ❌ **Real-time Medical/Legal Advice**: Should not be used for critical decision-making
-- ❌ **Fact Verification**: Not designed to validate factual accuracy of statements
+❌ **Not suitable for:**
+- Extractive answer span prediction (only classifies, doesn't extract)
+- Generative question answering
+- Non-English languages
+- Very long documents (>256 tokens without truncation)
+- Medical/legal decision-making
+- Fact verification
 
 ## Bias, Risks, and Limitations
 
-### Known Limitations
+<!-- This section is meant to convey both technical and sociotechnical limitations. -->
 
-1. **Context Length Restriction**: Maximum 256 tokens may truncate important information in long documents
-2. **Wikipedia Bias**: Training on Wikipedia-based questions may not generalize perfectly to other domains
-3. **Binary Yes/No Ambiguity**: Complex questions requiring nuanced answers may be misclassified as yes/no
-4. **Temporal Knowledge Cutoff**: Training data reflects knowledge up to a certain date
-5. **Language Variety**: May perform differently across English dialects and formal/informal language
-6. **Sample Size**: Trained on 10,000 examples; full dataset training could improve performance
+**Limitations:**
+- Context limited to 256 tokens
+- Wikipedia-biased training data
+- Trained on 10,000 examples (subset of full dataset)
+- May struggle with complex reasoning questions
 
-### Potential Biases
+**Biases:**
+- Better on factual "what/when/where" questions
+- Inherits biases from Wikipedia and base model
+- Performance varies across domains
 
-- **Topic Bias**: Better performance on Wikipedia-common topics (history, geography, science)
-- **Question Type Bias**: May favor factual "what/when/where" questions over complex "why/how" questions
-- **Cultural Bias**: Inherits biases from DeBERTa pre-training and Wikipedia content
-- **Length Bias**: Performance may vary based on context and question length
-- **Demographic Representation**: Training data may not equally represent all perspectives
-
-### Risks
-
-- **Overconfidence**: Model may confidently predict "has answer" even when context is ambiguous
-- **False Negatives**: May miss valid answers in complex or indirect phrasings
-- **Adversarial Vulnerability**: Can be fooled by carefully crafted misleading contexts
-- **Downstream Amplification**: Errors in classification stage cascade to downstream QA components
+**Risks:**
+- May be overconfident on ambiguous inputs
+- False negatives on complex phrasings
+- Vulnerable to adversarial examples
 
 ### Recommendations
 
-Users should:
+<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->
 
-- ✅ **Validate Critical Applications**: Implement human-in-the-loop for high-stakes decisions
-- ✅ **Monitor Performance**: Track metrics across different question types and domains
-- ✅ **Calibrate Thresholds**: Adjust confidence thresholds based on use case requirements
-- ✅ **Test Diverse Inputs**: Evaluate on representative samples from target domain
-- ✅ **Combine with Other Signals**: Use as one component in multi-model systems
-- ✅ **Regular Updates**: Retrain periodically with new data to maintain performance
+Users should:
+- ✅ Implement human review for critical applications
+- ✅ Monitor performance across different domains
+- ✅ Calibrate confidence thresholds for use case
+- ✅ Test on representative samples
+- ✅ Use as one component in multi-model systems
