Evaluation of a trust-modulated argumentation-based interactive decision-making tool

摘要

The interactive ArgTrust application is a decision-making tool that is based on an underlying formal system of argumentation in which the evidence that influences a recommendation, or conclusion, is modulated according to values of trust that the user places in that evidence. This paper presents the design and analysis of a user study which was intended to evaluate the effectiveness of ArgTrust in a collaborative human–agent decision-making task. The results show that users’ interactions with ArgTrust helped them consider their decisions more carefully than without using the software tool.
