Chatbot using NLP and Deep Learning

📌 Project Overview

This project is an AI-powered chatbot that uses Natural Language Processing (NLP) and Deep Learning to understand user queries and generate human-like responses. The chatbot can be used in applications like customer support, virtual assistants, education platforms, and more.

🎯 Objective

To build an intelligent and interactive chatbot capable of understanding and responding to user inputs in natural language using deep learning techniques.

✅ Features

• Conversational chatbot using NLP and deep learning models
• Preprocessing of user input (tokenization, stemming, lemmatization)
• Intent classification using neural networks
• Support for predefined intents and custom dataset
• Text-based interface (console or web UI)
• Memory-based or context-aware conversation (optional)

🛠 Technologies Used

• Programming Language: Python
• Deep Learning Frameworks: TensorFlow / PyTorch
• NLP Tools: NLTK, spaCy, Hugging Face Transformers
• Model Type: Seq2Seq (LSTM/GRU), Transformer, or BERT-based model
• Web Integration (Optional): Flask, Django, or Streamlit
• Dataset: Custom intents.json or public datasets (Cornell Movie Dialogs, etc.)

🧠 How It Works

1. Input: User types a message.
2. Preprocessing: Text is tokenized, stemmed/lemmatized.
3. Intent Classification: Deep learning model predicts the user's intent.
4. Response Generation: Bot selects the best response from the intent or generates new text (if generative model used).
5. Output: The response is displayed or spoken (via TTS).

🚀 Future Enhancements

• Add voice support (Speech-to-Text & Text-to-Speech)
• Use Transformer models like GPT/BERT for advanced conversations
• Contextual memory-based responses
• Deploy on cloud (AWS, Azure, Heroku)
• Multilingual conversations

🌟 Use Cases

• Customer Service Bots
• Virtual Assistants
• Educational Chatbots
• Healthcare Query Assistants
• E-commerce Product Support
