Conversational AI for Reservation Placement

Group: Razvan Radoi, Bogdan Radulescu, Vlad Neculae.

Problem Statement

One of the most advanced pieces of software is represented by conversational AIs. With a long-standing fasciation for machine dialogue and clear convenience brought to the table, conversational AIs have become increasingly popular. With modern day software, in fact, they are a hot commodity. A key feature of these conversational AIs is task-oriented dialogue: A feature that lets the user place orders or make reservations through speech. Thus, the need for domain-specific chatbots arises: a series of task-focused chat bots that is able to interact with users through human-like speech that help them with completing tasks like reservations or order placements.

Deliverables

The deliverables of this project are as follows:

  1. A trained model of a chatbot that interacts with a subset of MultiWOZ that contains single-domain dialogues focused around restaurants reservations
  2. An adjusted subset of MultiWOZ that is altered for RASA 2.X, 3.X and beyond input
  3. A simple API for interacting with the restaurants database through RASA Actions
  4. Config files needed for local RASA deployment and full interaction

Set-up Steps

Requirements: Python 3.7 (3.8 and beyond not supported as of now for re-training due to current spacy limitations)

  1. Clone this repository
  2. Install RASA X
pip install rasa-x -i https://pypi.rasa.com/simple
  1. In a terminal run:
rasa run actions
  1. In a second terminal, run:
rasa shell
  1. You may now interact with the chatbot from the second terminal, through the rasa shell
