RAS question
Natural Language Processing (NLP) is a branch of AI that deals with:
Correct answer: (C) Interaction between computers and human language.
Natural Language Processing is the branch of artificial intelligence concerned with interaction between computers and human language.
Explanation
Natural Language Processing, or NLP, enables computers to work with human language: to understand it, interpret it, generate it, and respond to it in written or spoken form. That is why the option about interaction between computers and human language is the precise answer. Britannica describes NLP in computer science as the use of operations, systems and technologies that allow computers to process and respond to written and spoken language in a human-like way. The examples also match the exam explanation: chatbots, machine translation, speech recognition, text summarisation, sentiment analysis and search engines all depend on language handling rather than hardware design, physical motion or image analysis. In India, Bhashini is an application-facing example because it uses NLP for translation across 22 scheduled languages.
Why the other options are wrong
- (A) Circuit design belongs to electronic design automation and VLSI, where the task is designing electronic circuits rather than processing human language.
- (B) Robot movement is a robotics and control-systems problem, focused on physical motion rather than interpreting or generating language.
- (D) Image recognition is part of computer vision, which analyses visual patterns, not written or spoken human language.
Concept
This tests the basic AI sub-fields in the Science and Technology syllabus. It recurs in RAS because exam questions often ask candidates to distinguish NLP, robotics, computer vision and hardware-related domains through their core applications.
