1. Introduction to Natural Language Processing (NLP)

This document provides an introduction to the field of Natural Language Processing (NLP).

1.1 Applications of NLP

Natural Language Processing (NLP) has a wide range of real-world applications, including:

• Text Analysis: Understanding and extracting information from unstructured text data.
• Machine Translation: Automatically translating text from one language to another.
• Sentiment Analysis: Determining the emotional tone or opinion expressed in text.
• Chatbots and Virtual Assistants: Enabling human-like conversations with computers.
• Speech Recognition: Converting spoken language into text.
• Text Summarization: Generating concise summaries of longer documents.
• Information Retrieval: Finding relevant information within large collections of text.

1.2 What is NLP?

Natural Language Processing (NLP) is a subfield of artificial intelligence (AI) that focuses on enabling computers to understand, interpret, and generate human language. It combines principles from computer science, linguistics, and machine learning to bridge the gap between human communication and computer understanding.

At its core, NLP aims to allow computers to process and analyze natural language data in a way that is meaningful and useful. This involves tasks such as:

• Understanding meaning: Grasping the semantic content of words, phrases, and sentences.
• Recognizing intent: Identifying the purpose or goal behind a piece of text or speech.
• Generating coherent text: Creating human-like text that is grammatically correct and contextually relevant.
