About The Project

• The implementation should be easy to follow for beginners and provide a basic understanding of chatbots.
• The implementation is straightforward with a Feed Forward Neural net with 2 hidden layers. Customization for your own use case is super easy. Just modify intents.json with possible patterns and responses and re-run the training.

Built With

This section should list any major frameworks that you built your project using. Leave any add-ons/plugins for the acknowledgements section. Here are a few examples.

• Pytorch
• Natural Language Toolkit
• Numpy

Getting Started

To get started with this project, follow the instructions below:

Prerequisites

To run and work with this project you need to have the latest version of Python installed in your system.

Along with Python, we would also need some python modules to work with this project. Check Installation for instructions on same.

Installation

1. Clone the repo

   git clone https://github.com/mindninjaX/AI-Chatbot

2. Install required packages using pip install

   pip install torch
   pip install numpy
   pip install nltk

3. Uncomment nltk.download() & run nltk_utlis.py to install Punkt Tokenzier model

   import nltk
   nltk.download()

Usage

Run train.py to train the chatbot

python train.py

This is create a new file data.pth which contains the trained data for our chatbot.

Initiate the chatbot! Run chat.py

python chat.py

Customize

Raw data is present in intents.json. Customize this file as per your needs. Just define a new tag, possible patterns, and possible responses for the chat bot. You have to re-run the training whenever this file is modified.

{
"intents": [
  {
    "tag": "greeting",
    "patterns": [
      "Hi",
      "Hey",
      "How are you",
      "Is anyone there?",
      "Hello",
      "Good day"

      "Hi there, what can I do for you?",
      "Hi there, how can I help?"
    ]
  },
  ...
]
}
