or even free text (like doctor’s notes, prescriptions, opinion surveys, etc.)
Brainy Fact
An AI is never held responsible for its actions. The human is held accountable for its action
whether it is good or bad.
Natural Language Processing (NLP)
Natural Language Processing, usually shortened as NLP, is a domain of AI which works with
the interactions between humans and computer systems using natural language. Most of the
voice recognition apps like Siri, Alexa, Meta AI, etc., use NLP to process the audio input. It is
the sub field of AI that uses computer-based methods to analyse and understand language in
speech and text.
The aim of NLP is to read, decode, understand and bring logical results of the human languages
to make sense.
Different types of NLP include:
• Optical Character Recognition for converting written and printed text into data.
• Speech Recognition involves converting spoken words into data.
• Machine Translation where the source language is translated into target language without
human interference.
• Natural Language Generation is a software process which converts structured data into natural
language.
• Sentiment Analysis is a process used to determine whether a piece of text is positive, negative
or neutral.
• Semantic Search is understanding the intention behind any search. It also optimises the search
operation by giving possible search predictions.
