A functional PoC chatbot inspired from Google's DialogFlow

DialogFlow is a framework by google that allow developers to create their own goal oriented chatbot using Machine Learning and NLP.

It primarily functions in 4 different phase:

(1) It classifies the Intent using an LSTM Intent Classifier.
(2) It parses all the Entities from the given text input.
(3) The Entities are then passed to an Action(a function) associated with the Intent.
(4) A Sequence-to-Sequence model is used to generate the final output response.

Dataflow for the weather intent :

Our model uses a simple 3 Layered Intent Classifier.

The First layer is an LSTM followes by 2 Dense layers.

The Entity Parser uses Spacy library to do NLP tasks

Functions to parse weather, do a search, etc....

The Dialog Generation is done by a Sequence-to-Sequence Model.

The python files are stored in the './src/' folder. A standalone jupyter notebook is saved inside the folder notebook. The Folder imgs contain screenshots of the program.

Run the file 'main.py' inside the folder './src' to run the program.

* Estimated time for the application to load : 36 seconds

Try typing Hi or hello.....

Try asking about the weather.....
