QA Generation#

This notebook shows how to use the QAGenerationChain to come up with question-answer pairs over a specific document. This is important because often times you may not have data to evaluate your question-answer system over, so this is a cheap and lightweight way to generate it!

 'answer': 'The U.S. Department of Justice is assembling a dedicated task force to go after the crimes of Russian oligarchs.'}
