  • ABS4GD: a multi-agent system that simulates group decision processes considering emotional and argumentative aspects
    Publication . Marreiros, Goreti; Santos, Ricardo; Ramos, Carlos; Neves, José; Bulas-Cruz, José
    Emotion although being an important factor in our every day life it is many times forgotten in the development of systems to be used by persons. In this work we present an architecture for a ubiquitous group decision support system able to support persons in group decision processes. The system considers the emotional factors of the intervenient participants, as well as the argumentation between them. Particular attention will be taken to one of components of this system: the multi-agent simulator, modeling the human participants, considering emotional characteristics, and allowing the exchanges of hypothetic arguments among the participants.

  • Acoustic and Temporal Analysis of swallowing sounds: use of electronic stethoscope on cervical auscultation
    Publication . Pereira, Nelson; Faria, Paula; Santos, Ricardo; Araújo, André; Esperança, Joana; Pinheiro De Sousa, Andreia Sofia
    Swallowing is a physiologic function consisting in the propulsion of the bolus into the stomach, with effective respiratory protection. Clinical intervention of Speech and Language Therapists requires improved and reliable methods of swallowing evaluation. Cervical Auscultation (CA) is especially appreciated as a noninvasive method. However, conventional stethoscopes do not provide quantitative measures to complement the perceptive auditory analysis of the swallowing sounds

  • Agent based simulation for group formation
    Publication . Marreiros, Goreti; Santos, Ricardo; Ramos, Carlos; Neves, José
    Group decision making plays an important role in today’s organisations. The impact of decision making is so high and complex, that rarely the decision making process is made just by one individual. The simulation of group decision making through a Multi-Agent System is a very interesting research topic. The purpose of this paper it to specify the actors involved in the simulation of a group decision, to present a model to the process of group formation and to describe the approach made to implement that model. In the group formation model it is considered the existence of incomplete and negative information, which was identified as crucial to make the simulation closer to the reality.

  • Ambient intelligence in emotion based ubiquitous decision making
    Publication . Marreiros, Goreti; Santos, Ricardo; Ramos, Carlos; Neves, José; Novais, Paulo; Machado, José; Bulas-Cruz, José
    As the time goes on, it is a question of common sense to involve in the process of decision making people scattered around the globe. Groups are created in a formal or informal way, exchange ideas or engage in a process of argumentation and counterargumentation, negotiate, cooperate, collaborate or even discuss techniques and/or methodologies for problem solving. In this work it is proposed an agent-based architecture to support a ubiquitous group decision support system, i.e. based on the concept of agent, which is able to exhibit intelligent, and emotional-aware behaviour, and support argumentation, through interaction with individual persons or groups. It is enforced the paradigm of Mixed Initiative Systems, so the initiative is to be pushed by human users and/or intelligent agents.

  • Context-aware emotion-based model for group decision making
    Publication . Marreiros, Goreti; Santos, Ricardo; Ramos, Carlos; Neves, José
    Involving groups in important management processes such as decision making has several advantages. By discussing and combining ideas, counter ideas, critical opinions, identified constraints, and alternatives, a group of individuals can test potentially better solutions, sometimes in the form of new products, services, and plans. In the past few decades, operations research, AI, and computer science have had tremendous success creating software systems that can achieve optimal solutions, even for complex problems. The only drawback is that people don’t always agree with these solutions. Sometimes this dissatisfaction is due to an incorrect parameterization of the problem. Nevertheless, the reasons people don’t like a solution might not be quantifiable, because those reasons are often based on aspects such as emotion, mood, and personality. At the same time, monolithic individual decisionsupport systems centered on optimizing solutions are being replaced by collaborative systems and group decision-support systems (GDSSs) that focus more on establishing connections between people in organizations. These systems follow a kind of social paradigm. Combining both optimization- and socialcentered approaches is a topic of current research. However, even if such a hybrid approach can be developed, it will still miss an essential point: the emotional nature of group participants in decision-making tasks. We’ve developed a context-aware emotion based model to design intelligent agents for group decision-making processes. To evaluate this model, we’ve incorporated it in an agent-based simulator called ABS4GD (Agent-Based Simulation for Group Decision), which we developed. This multiagent simulator considers emotion- and argument based factors while supporting group decision-making processes. Experiments show that agents endowed with emotional awareness achieve agreements more quickly than those without such awareness. Hence, participant agents that integrate emotional factors in their judgments can be more successful because, in exchanging arguments with other agents, they consider the emotional nature of group decision making.

  • Hardware and software in smart decision rooms
    Publication . Freitas, Carlos Filipe; Marreiros, Goreti; Santos, Ricardo; Ramos, Carlos
    Since the last decade research in Group Decision Making area have been focus in the building of meeting rooms that could support the decision making task and improve the quality of those decisions. However the emergence of Ambient Intelligence concept contributes with a new perspective, a different way of viewing traditional decision rooms. In this paper we will present an overview of Smart Decision Rooms providing Intelligence to the meeting environment, and we will also present LAID, an Ambient Intelligence Environment oriented to support Group Decision Making and some of the software tools that we already have installed in this environment.

  • LAID - a smart decision room with ambient intelligence for group decision making and argumentation support considering emotional aspects
    Publication . Marreiros, Goreti; Santos, Ricardo; Freitas, Carlos Filipe; Ramos, Carlos; Neves, José; Bulas-Cruz, José
    Decision Making is one of the most important activities of the human being. Nowadays decisions imply to consider many different points of view, so decisions are commonly taken by formal or informal groups of persons. Groups exchange ideas or engage in a process of argumentation and counter-argumentation, negotiate, cooperate, collaborate or even discuss techniques and/or methodologies for problem solving. Group Decision Making is a social activity in which the discussion and results consider a combination of rational and emotional aspects. In this paper we will present a Smart Decision Room, LAID (Laboratory of Ambient Intelligence for Decision Making). In LAID environment it is provided the support to meeting room participants in the argumentation and decision making processes, combining rational and emotional aspects.
