At a Glance
• Natural language refers to the language humans use to communicate with one another.
• Natural Language Processing (NLP) is a subfield of Artificial Intelligence that focuses on enabling computers,
through specialised programs, to perform tasks such as speech recognition, translation, and the analysis and
extraction of large amounts of natural language data.
• Some of the real-life applications of NLP are Automatic Text Summarisation, Autogenerated Captions, Language
Translation, Sentiment and Emotion Analysis, Text Classification, Voice assistants, etc.
• The stages of NLP are Lexical Analysis, Syntactic Analysis, Semantic Analysis, Discourse Integration, and Pragmatic
Analysis.
• Chatbot is an AI enabled computer program that communicates with the user in natural human language either
through voice or text.
• Text normalisation is the process of cleaning textual data by converting it into a standard form.
• A corpus is a large collection of text, such as articles, rhymes, or email.
• Stemming is the process of removing the affixes from the words to reduce them to their root words.
• Lemmatization is a process of removing the affixes from the words to create a meaningful root word.
