Actions Folder

This folder contains the implementations for custom actions.

• The implementation can be found in the actions.py file.

Data Folder

This folder contains the main implementations of the Chatbot.

• The nlu.yml file contains the implementations for the NLU portion of the chatbot. Here, intents such as greet and ask_product are implemented to give the bot test cases to identify certain intents of the user.
• The rules.yml file represents the pre-set rules for user inputs. Rules ensure a certain flow of events will occur upon certain user inputs.
• The stories.yml file contains the various use cases that are anticipated by the user. These give the chatbot a guide to structure conversations and allows for custom inputs to be crafted.

DB Folder

This folder contains the implementation of a mock database to be queried by the chatbot. The database has been implemented in SQLite and is edited using a database editor

• The connectdb.ipynb file represents a python jupyter notebook which contains the testing code for the database to ensure that data can be retrieved and is of working order.
• The database1.db file contains the implementation of the database in SQLite

Models Folder

This folder contains the trained models for the chatbot. Once the files have been downloaded, the chatbot can be trained by running the following command while in the file.

rasa run action
rasa shell

config.yml

This file contains the implementation for the display and Memoization policy of the chatbot

credentials.yml

This file contains the implementations for external implementations

domain.yml

This file contains the implementations for the responses and actions that the bot can provide a user.
