Question Answering (QA) is a computer science discipline within the fields of information retrieval and natural language processing (NLP), which is concerned with building systems that automatically answer questions posed by humans in a natural language.
Question answering programs can construct answers through the query of a knowledge base (a structured database of knowledge) or an unstructured collection of documents in a natural language.
