BERT Fine-Tuned on SQuAD (Extractive Question Answering)
This model extracts answers to questions directly from a provided text passage.
It was fine-tuned from bert-base-cased on the SQuAD v1.1 dataset.
How It Works
Given a context (a paragraph of text) and a question, the model finds and returns the exact span of text in the context that answers the question.
