Natural Language Processing
Natural language is the language used by humans to communicate with each other by writing or speaking. Natural
Language Processing (NLP) is the domain of artificial intelligence focused on enabling machines to understand,
analyse, and interact with humans through natural language. NLP works with two main types of data: text and
speech. It combines the fields of linguistics and computer science to analyse language structure and provide
guidelines to make models which can comprehend, break down and separate significant details from text and
speech. For example, social media platforms like X (formerly Twitter) use NLP to identify and filter out harmful
content in user tweets. Amazon uses NLP to analyse customer reviews and improve user experience.
Applications of Natural Language Processing
Some of the real-time applications of NLP are:
• Plagiarism Checker: It uses NLP to search through online repositories and
identify any cases of published content that match your work line by line,
warning you about them.
• Email Filters: In Gmail, emails are automatically categorised into three primary
tabs: Primary, Social, and Promotions. NLP identifies specific keywords,
phrases, and patterns to determine the appropriate category for each email.
Similarly, emails marked as Spam are filtered using the same NLP techniques.
By analysing suspicious content, sender behaviour, and common spam indicators, Gmail ensures that potentially
harmful or irrelevant emails are directed to the Spam folder.
• Chatbots: Chatbots are software applications that use NLP to communicate with users
via text or speech. Smart assistants like Alexa and Siri understand the speech pattern of
the instructions and execute them.
• Sentiment Analysis: Sentiment analysis is commonly
used on social media platforms to analyse the
emotional tone of posts, comments, or reviews,
categorising them as positive, negative, or neutral.
• Language Translation: Tools like Google Translate employ NLP to
convert text from one language to another by analysing sentence
structures and context for accurate translations.
