📄 Overview

This repository contains a presentation that provides an introduction to Natural Language Processing (NLP), a field within Artificial Intelligence focused on enabling computers to understand, interpret, and generate human language. This presentation covers fundamental concepts, techniques, and real-world applications of NLP, highlighting how it transforms unstructured text data into valuable insights.

📚 Topics Covered

1. Introduction to NLP

   • What is NLP?
   • Importance of NLP in various industries

2. NLP Pipeline

   • Overview of the NLP pipeline stages
   • Machine learning vs. deep learning approaches

3. Common NLP Techniques

   • Tokenization: Breaking text into words or sentences
   • Stopword Removal: Filtering out commonly used words (e.g., "the", "is")
   • Stemming and Lemmatization: Reducing words to their base form
   • Named Entity Recognition (NER): Identifying entities like names, places, dates
   • Part-of-Speech (POS) Tagging: Assigning grammatical labels (e.g., noun, verb)
   • Text Vectorization (TF-IDF, Bag of Words): Converting text into numerical form
   • Sentiment Analysis: Determining positive, negative, or neutral sentiment
   • Text Classification: Categorizing text into predefined labels
   • Word Embeddings (Word2Vec, GloVe, BERT): Mapping words to dense vectors
   • Topic Modeling (LDA): Identifying themes within text data

4. Practical Use Cases

   • Customer Feedback Analysis: Analyzing product reviews to improve recommendations
   • Chatbots & Virtual Assistants: Automating responses in customer service
   • Healthcare: Assisting in diagnosis by analyzing patient data
