Shame, when reasoning and emotions are linked

Short paperInternational audienceSome emotions, described as "basic" in the literature, are almost reflexes. Other emotions are triggered via pattern matching mechanisms operating on specific mental states (most often epistemic and motivational) to determine the (in)congruence of these states. Yet other emotions come from more or less complex cognitive mechanisms (and we thus call them complex emotions) such as counterfactual reasoning (e.g. guilt or regret), normative judgement (e.g. shame or pride), probabilistic evaluations of the world (e.g. surprise), etc.. In the following, we study and formalise the complex emotion of shame that is of particular importance in social behaviour, and illustrate it on some scenarios

Towards a Model of Open and Reliable Cognitive Multiagent Systems: Dealing with Trust and Emotions

 Open multiagent systems are those in which the agents can enter or leave the system freely. In these systems any entity with unknown intention can occupy the environment. For this scenario trust and reputation mechanisms should be used to choose partners in order to request services or delegate tasks. Trust and reputation models have been proposed in the Multiagent Systems area as a way to assist agents to select good partners in order to improve interactions between them. Most of the trust and reputation models proposed in the literature take into account their functional aspects, but not how they affect the reasoning cycle of the agent. That is, under the perspective of the agent, a trust model is usually just a “black box” and the agents usually does not take into account their emotional state to make decisions as well as humans often do. As well as trust, agent’s emotions also have been studied with the aim of making the actions and reactions of the agents more like those of humans being in order to imitate their reasoning and decision making mechanisms. In this paper we analyse some proposed models found in the literature and propose a BDI and multi-context based agent model which includes emotional reasoning to lead trust and reputation in open multiagent systems

Um modelo de confiança baseado em emoções para agentes

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Ciência da Computação, Florianópolis, 2014.Em sistemas multiagente, modelos de confiança e reputação vêm sendo propostos com o objetivo de auxiliar os agentes a selecionar seus parceiros de interação, visando aumentar o número de interações bem sucedidas. Assim como a confiança, emoções em agentes também são objetos de estudo tendo o objetivo de tornar as ações e reações dos agentes mais semelhantes a dos humanos. Essa dissertação apresenta um modelo de confiança baseado em emoções. Trata-se portanto de um modelo híbrido, que integra ao enfoque matemático característico dos modelos de confiança e reputação, um mecanismo de raciocínio simbólico, visando capturar a complexidade do raciocínio e flexibilizar as avaliações essencialmente quantitativas feitas pelos agentes através da introdução de elementos de natureza qualitativa ao cálculo da confiança. O modelo proposto incorpora oito emoções ao modelo de confiança Regret. Na parte inicial do trabalho é feita uma análise de modelos de confiança para agentes, do modelo OCC e de modelos de emoções para agentes. A parte principal do trabalho corresponde a proposta do modelo, que envolve a formalização das emoções e a modelagem das funções relativas às emoções. Ao final, dois cenários distintos são simulados para testar a funcionalidade do modelo.2014-08-06T17:58:19
