What is the purpose of the 'context' input in hf.questionAnswering?

[ArsalaBangash]

Background

The args for QuestionAnswering are context and question.

export type QuestionAnsweringArgs = BaseArgs & {
	inputs: {
		context: string;
		question: string;
	};
};

The example in the docs is

await hf.questionAnswering({
  model: 'deepset/roberta-base-squad2',
  inputs: {
    question: 'What is the capital of France?',
    context: 'The capital of France is Paris.'
  }
})

Question

What is the purpose of the context input? Could the model return the right answer without it?

Thank you!

This is "classical" question answering, so the output is always extracted from the context (a span of text taken from the context)

I see. That clears it up for me.

Would a PR explaining such in the docs be welcome?
