Natural Language Processing (NLP) is a branch of Artificial Intelligence (AI). It is a study of how machines understand the language of humans. It aims to build systems that can understand text and perform tasks like language translation and classifying a topic. NLP has many applications. NLP tools help to process unstructured data. Question
Answering (QA) system or information retrieval system falls under the category of NLP. The QA system mainly involves two methods, question analysis and answer extraction. Intelligent QA systems have always outperformed the non-intelligent QA systems. It is a neural network that is incorporated with the QA system to make it intelligent. Neural networks(NN) are a series of algorithms that are used to mimic the operations of a human brain to understand the relationships between data. NN can learn by themselves and produce the output that is not limited to the input provided to them.
