This model is based on bert-base-uncased and was fine-tuned on the SQuAD v1.1 dataset for extractive question answering. It takes a question and a context passage as input and predicts the span of text in the passage that most likely answers the question.

The model was trained using the Hugging Face 🤗 Transformers library.

Intended Uses & Limitations

Intended Uses

Extractive question answering on Wikipedia-style passages.
As a downstream component in information retrieval pipelines.
Educational purposes or experimentation with fine-tuning on QA tasks.

Limitations

The model may not generalize well to out-of-domain datasets.
It does not handle unanswerable questions (not trained on SQuAD v2.0).
It may produce incorrect or misleading answers if context is ambiguous.

How to Use

You can load this model using the pipeline API:

python

from transformers import pipeline

qa_pipeline = pipeline("question-answering", model="tmt3103/SQuAD_BERT")
result = qa_pipeline({
    "context": "Hugging Face is creating a tool that democratizes AI.",
    "question": "What is Hugging Face creating?"
})
print(result)
