What is Natural Language Processing ?

Natural Language Processing (NLP) is a field of study that focuses on the interactions between human natural language and computers. The goal of NLP is to enable computers to understand, interpret, and generate human language. It is an interdisciplinary field that encompasses computer science, artificial intelligence, linguistics, and cognitive psychology. NLP techniques use a combination of machine learning, deep learning, and computational linguistic methods to process and analyze natural language text or speech.

These applications allow computers to understand and interpret human language, making it possible for machines to interact with humans in a more natural way.

Applications of NLP 

1. Text to speech: Transforming text data to speech. Example -Reading articles and generating the article (text) in speech form.
2. Speech to text : Transforming speech to text . Example - Subtitles in movies.
3. Language translation : Translating text in one language to other. Example - Google translator 
4. Sentiment analysis : Analyzing sentiments of text to identify the emotional tone in text. Example - Analysis of product reviews and finding sentiments in terms of positive, negative and neutral
5. Text summarization: Breaking large text into small so that it can be summarized in small text. Example - Book summary in few sentences
6. Named Entity Recognition: Identify key information from the text and classify into pre-defined categories. Example- Shahrukh Khan belongs to India (Location- India)
7. Question Answering: Providing answers to questions asked. Example :Q- Capital of India, A- Delhi
8. Dialogue Systems: System that interacts with human in natural language. Example -ChatGPT
9. Language Generation- Natural Language Generation (NLG) using machine learning and artificial intelligence. Example - Product descriptions
10. Language Understanding : Natural Language Understanding (NLU)  is used to understand users input either from text or speech by understanding intent. Example - Need to travel to USA-NLU understand intent i.e. travel ,location -USA
