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!

from langchain.document_loaders import TextLoader

loader = TextLoader("../../modules/state_of_the_union.txt")

doc = loader.load()[0]

from langchain.chat_models import ChatOpenAI
from langchain.chains import QAGenerationChain

chain = QAGenerationChain.from_llm(ChatOpenAI(temperature=0))

qa = chain.run(doc.page_content)

qa[1]

    {'question': 'What is the U.S. Department of Justice doing to combat the crimes of Russian oligarchs?',
     'answer': 'The U.S. Department of Justice is assembling a dedicated task force to go after the crimes of Russian oligarchs.'}
