What is Natural Language Processing?

Have you ever wondered how ChatGPT works? How does a computer understand your text and provide such relevant information? ChatGPT is a prime example of Natural Language Processing (NLP) in action, a field that’s revolutionizing our interactions with technology.

Natural Language Processing (NLP) is a branch of artificial intelligence (AI) focused on enabling computers to understand, interpret, and generate human language. By combining computational linguistics, computer science, and machine learning, NLP allows machines to process vast amounts of natural language data, making sophisticated language models and applications like ChatGPT possible.

Applications of NLP

NLP touches many aspects of our daily lives, transforming the way we interact with technology. Here are some common applications:

  • Spam Filters: Automatically detect and filter out unwanted emails based on content. This keeps your inbox clean and manageable.
