This project implements a chatbot connected to a webapp chatinterface that provides a conversational interface for the DCAT QA system. It was developed as part of the bachelorthesis "A Question Answering (QA) System for the Data Catalog Vocabulary (DCAT)".
In particular the project consists of nodejs app that:
- serves a web chat interface
- consumes all messages users send through the chat inteface
- uses botkit to manage conversations and implement all dialogs
- passes all questions to the specified QA system endpoint
- presents the results from the QA system to the user
The web bot is a part of the social network interface for the DCAT QA system. The following shows an overview of all components of the interface and how they communicate:
More info on the implementation details can be found in the thesis.
A live demo can be found here.
