Web-Gorgias-B: argumentation for allWeb-Gorgias-B: argumentation for all Δημοσίευση σε Συνέδριο Conference Publication 2023-06-292021enThis 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.http://creativecommons.org/licenses/by-nc-nd/4.0/286-29713th International Conference on Agents and Artificial IntelligenceProceedings of the 13th International Conference on Agents and Artificial IntelligenceSpanoudakis_et_al_ICAART_2_2021.pdfChania [Greece]Library of TUC2023-06-29application/pdf577.1 kBfree Spanoudakis Nikolaos Σπανουδακης Νικολαος Kostis Konstantinos Κωστης Κωνσταντινος Mania Aikaterini Μανια Αικατερινη Science and Technology Publications, Lda (SciTePress) Computational argumentation Knowledge representation and reasoning Knowledge engineering Hierarchical Argumentation Frameworks Web-based interaction Intelligent user interfaces
