Smart Python Chatbot (v2)

A Python-based chatbot that demonstrates basic artificial intelligence concepts through question handling and thoughtful response patterns. This chatbot can identify different types of questions and provide context-aware responses.

Features

• 🤔 Question type recognition (what, why, how)
• 💭 Topic extraction from questions
• 🎯 Pattern-based response generation
• 😊 Basic sentiment analysis
• 💡 POS (Part of Speech) tagging

Prerequisites

• Python 3.6 or higher
• NLTK library

Installation

1. Clone the repository:

git clone https://github.com/yourusername/smart-chatbot.git
cd smart-chatbot

2. Install required packages:

python setup.py

3. If you encounter NLTK errors, run Python and download required data:

import nltk
nltk.download('punkt')
nltk.download('vader_lexicon')
nltk.download('stopwords')
nltk.download('averaged_perceptron_tagger')

Example interactions:

Bot: Hi! I'm a smarter chatbot now. I can handle questions! Type 'bye' to exit.

You: What is machine learning?
Bot: Let me think about machine learning... 

You: How does a computer work?
Bot: Here's a way to approach computer operation...

You: Why is the sky blue?
Bot: The reason for sky color might be...

How It Works

Question Recognition

The chatbot identifies different types of questions:

• What questions (definitions and explanations)
• How questions (processes and methods)
• Why questions (reasons and causes)

Response Generation

• Templates based on question type
• Topic extraction from user queries
• Sentiment analysis for emotional context
• Fallback responses for unknown queries

Natural Language Processing

• Tokenization
• POS tagging
• Stop word removal
• Basic sentiment analysis

Common Issues & Solutions

Windows Users

• If 'python' is not recognized:
  • Add Python to PATH or use py instead of python
  • Use full path: C:\Users\YourName\AppData\Local\Programs\Python\Python3x\python.exe

NLTK Errors

• Run the NLTK downloads manually in Python console
• Ensure internet connection for downloading NLTK data
