Applicability Of Emotion To Intelligent Systems, Dionéia Motta Monte-Serrat, Carlo Cattani Oct 2022

Applicability Of Emotion To Intelligent Systems, Dionéia Motta Monte-Serrat, Carlo Cattani

Information Sciences Letters

We propose to investigate the connection between emotions and cognition in intelligent systems through the dynamic concept of language, which links context to logic in both human and machine language. For this, our approach is inspired on aspects of the information theory of Abraham Moles. We analyze emotions under the semantic dimension, linked to a subjective context, which gives rise or not to decisions. We demonstrate that intelligent systems can, on the one hand, work with previously categorized emotions (say in a frozen context); or, on the other hand, process information under a dynamic aspect. This is possible when considering …
