Towards Meaning Processes In Computers From Peircean Semiotics

Abstract: In this work, we propose a computational approach to the triadic model of semiosis (meaning processes), as stated by Charles Sanders Peirce. His model of semiosis represents a key element in the construction of the next generation of intelligent artifacts able to overcome current AI limitations, such as the symbol grounding problem. The contributions of the Peircean semiotics to the construction of intelligent systems were not yet systematically explored. In fact, most approaches in the literature adopt a naive definition of semiosis, which usually plays a secondary role in the study. Our research, on the other hand, strives for a strong theoretical foundation for meaning processes, as well as its realization within digital computers. We investigate theoretical constraints about the feasibility of simulated semiosis. These constraints, which are basic requirements for the simulation of semiosis, refer to the synthesis of irreducible triadic relations (Sign – Object – Interpretant). We examine the internal organization of the triad, that is, the relative position of its elements and how they relate to each other by determinative relations. We also suggest a multi-level (micro and macro-semiosis) computational approach based on self-organization principles. In this context, relations of determination are described as emergent properties of the system.

Sign Language Processing

Abstract: Sign languages present a unique and natural opportunity to investigate the cognitive mechanisms of language comprehension and production, particularly in terms of their universality. Sign-speech comparisons can lead to important theoretical insights about language processing. In the present paper, we enquire about the processing – recognition and production – of sign languages with special attention to the effects of age of acquisition and iconicity. Our aim is to provide a review of current findings about the psychological processes involved in sign language processing examining what aspects may be universal and what aspects are affected by modality.

Desenvolvimento psicológico, mediação semiótica e representações sociais: por uma articulação teórica e metodológica

Abstract: This paper attempts to analyze the integration of subjective, developmental and cognitive aspects of semiotic processes in a psychological context with the historical, institutional, and ideological grounding of sign systems in the sociocultural context. In this analysis, arguments against the mind/body dichotomy are reviewed, their implications examined and relations between the process of semiotic mediation and the theory of social representations are established. A psychosocial synthesis, providing both theoretical and empirical guidelines for Developmental Psychology, is proposed.. This is carried out through the integration of the analysis of speech acts in the study of personal paradigms, processes of developing conscious awareness and cognitive and metacognitive development.

Intentionality and the theory of signs

Abstract: FgANZ BREWrANO wrote, in a well-known passage, that intentionality is peculiar to psychical phenomena. No physical phenomenon, he said, shows anything like it; hence intentionality affords us a criterion of the mental or psychical? Let us refer to this view as "Brentano's thesis." Among the phenomena which he would have called "intentional" is the interpretation of signs. One may ask, is it possible to provide an adequate theory of signs which will show Brentano's thesis to be mistaken? In the present paper I shall make certain general points which, I believe, must be considered in any attempt to answer this question, I shall first attempt to state Brentano's thesis somewhat more exactly; then I shall turn to the analysis of the concept sign.
