    • Proposal for a Purchasing Decision Support System Based on Computational Semiotics.
      (Denis Martins)

      This research aims to conceive and develop a Decision Support System for purchases decision using the concepts of meaning and cognitive mechanisms studied by Semiotics; such principles, studied by Charles Sanders Peirce. Building a decision support approach based on these concepts, produce a system capable of performing the analysis of products using the attributes of which they are composed and the preferences set by the consumer, resulting in faster and customized decision-making, differing for each user.

    • Human-Machine Interface Context Sensitive in Intensive Care Units Based on Principles of Computational Semiotics.
      (Paulo Epifânio)

      This research proposes an interface based on Computational Semiotics for perceive changes in patient's clinical status, and discover hidden relationships among the vital signs and other parameters monitored in ICU, and therefore suggest medical interventions semantically relevant.To perform these tasks, the computational interface was designed to be executed in two ways: one to act in a way of acquiring knowledge, constructing knowledge from the readings of the signals from the patient, and the other to use of knowledge gained in times of medical intervention required.

    • Preliminary Studies of the Semeiose Automatic Perception Subsystem Intelligent Agents.
      (Rafael Barros)

      This research has focused to carry out a preliminary study on the incorporation of semiotic processes in intelligent agents. From this study, we propose an approach using the concepts entered by Charles Sanders Pierce, where agents are capable of automatic semeiosis with some degree of limitation. From the examples presented in this monograph, the new approach has achieved its initial goal, as the artificial intelligent agents are capable of acting: (i) subjectively as the consulting their knowledge about the world through the new process of signification put forward her; and (ii) adaptively as they use their perspective of the world to act more appropriately in situations that are presented to them.
