Introduction:

Artificial Intelligence (AI) and Natural Language Processing (NLP) are two important technologies that have changed how computers interact with human language. AI and NLP have led to many useful tools like virtual assistants such as Siri and Alexa, language translation apps, and systems that can understand how people feel. Furthermore, it’s important to understand the basics of AI and NLP and how they work together to see how they are used in modern technology.

Here’s an explanation of each:

What is Natural Language Processing (NLP)?

Natural Language Processing, or NLP, is a type of artificial intelligence (AI) that helps computers understand and work with human language. The main goal of NLP is to allow computers to read, understand, and respond to things we say or write.

Key Parts of NLP

• Tokenization: This means breaking down a sentence into smaller pieces like words or phrases. It helps the computer understand the text better.
• Part-of-Speech Tagging: This is labeling each word in a sentence with its part of speech, like a noun, verb, or adjective. It helps the computer understand how words are used.
• Named Entity Recognition (NER): This is finding and classifying names in text, like names of people, places, or organizations.
• Parsing: Parsing is analyzing the structure of a sentence to understand how the words are related.
• Sentiment Analysis: This is figuring out the emotion or feeling in a piece of text, like if it’s happy, sad, or angry.
• Language Modeling: This involves predicting the next word in a sentence, which helps in tasks like writing text and translating languages.

Applications of NLP

• Machine Translation: NLP helps translate text from one language to another, like using Google Translate.
• Chatbots and Virtual Assistants: NLP powers tools like Siri and Alexa, allowing them to understand and respond to our questions.
