What is Question Answering (QA)? 

Question answering (QA) is a type of artificial intelligence designed to answer questions asked by humans. QA systems are designed to understand natural language input and provide accurate and relevant responses to questions.

There are different types of QA systems, including rule-based systems which rely on a predetermined set of rules to provide answers, and machine learning-based systems which use algorithms to learn from a large dataset and provide answers based on that learning.
