NL Emoji Conversational Bot

NL Emoji Conversational Bot API 😻🔥

This is a project that tries to play around with the power of a very simple NL engine, defined as a feedforward (fully connected) neural network in Tensorflow, using softmax activation with a regression in the end. So, we're basically transforming the NL problem into an intent classification problem. Cool, right?

This project has a 'bot' in its engine, and uses Flask for exposing an API through /chat for interacting with the bot. Currently, you're able to tell the bot what mood you're in, what your favourite emoji is (and store it by doing so in a small SQL DB), and ask the bot what your favourite emoji is.

Requirements

💻 Computer 🐍 Python 🦄 APIs in requirements.txt

This project contains:

Bot

A conversational 'bot', trained on data defined in intents.json. Able to infer the intent of a sentence/conversation and reply in a manner you define.

Known issues: Mixing up the save/return_saved domains. Currently, I've only seen correct mapping by saying 'What's my favourite' for retreiving favourite emoji, everything else maps to save 🤷🏻‍♂️

Flask Server

Flask microservice for creating and exposing API through /chat.

API

Example call:

/chat?username=oktay&query=hi my favourite emoji is 😈

Database

SQLAlchemy DB for ease, storing user favourite emojis.

Model + Training

There's a trained model in the /bot catalog. If you want to train again with new data, run training in bot.py by executing python bot.py

How to Run

First off, create the database: python create_db.py

Then you're ready to go! Create the webserver: python app.py

There's a very simple UI that you can find at index to talk to the bot, http://127.0.0.1:5000/
