What is it about?
The WebGorgiasB Authoring Tool is an on-line implementation of the Gorgias-B system focusing on aiding people that have little, or no knowledge of logic programming, or of an argumentation framework, to develop argumentation-based decision policies. To achieve this, it provides an implementation of the table formalism proposed by Kakas, Moraitis and Spanoudakis (2019). The main original feature of the proposed system is the ability to define a default preferred option in a given scenario, thus, allowing for other options to be used in further refinements of the scenario.

Why is it important?
Argumentation is valuable for modern AI applications that need to be explainable (XAI). However, to write an argumentation theory is a complex task, usually undertaken by specialists that are hard to find. This work allows naive users to define their theories visually and automatically generate their code for the Gorgias argumentation framework.
Perspectives
This work explores the table formalism that allows to develop argumentation theories using a table whose rows correspond to scenarios and columns to decision options. The cells indicate if an option is valid in a given scenario.

Definition of a decision policy for handling coupons using the WebGorgiasB authoring tool
In this video I give a tutorial on the use of the WebGorgiasB tool. The tutorial is about defining an argumentation theory for a cognitive assistant agent who will handle discount coupons on behalf of the user.
Web-Gorgias-B: Argumentation for All
This paper proposes the use of a web-based authoring tool for the development of applications of argumentation. It focuses on aiding people that have little, or no knowledge of logic programming, or of an argumentation framework, to develop argumentation-based decision policies. To achieve this, it proposes an implementation of the table formalism that has recently been proposed in the literature. The proposed implementation contains original features that were evaluated by experts in web-application development, students and experts in argumentation. The main feature of the proposed system is the ability to define a default preferred option in a given scenario, thus, allowing for other options to be used in further refinements of the scenario. We followed a user-centered development process using the think aloud protocol. We evaluated the usability of the system with the System Usability Scale, validating our hypothesis that even naive users can employ it to define their decision policies
