This paper deals with the influence of the context in fuzzy rule base systems. The linguistic variable definition of Zadeh is modified to permit context adaptation, and inference procedure is modified to handle context adaptation when evaluating fuzzy concepts. Procedures to determine context in different situations are provided. Context determination may(More)
The literacy level of a significant part of the Brazilian population is insufficient for a proficient use of computers and for an autonomous access to digital contents as those currently available on the Internet. Although this problem also exists in other developing countries, its features depend on many sociocultural and educational factors that(More)
In this paper we discuss a set of conceptual issues regarding the synthesis of semiotic processes within artificial systems, and its technological offspring, the semionic networks. We start by putting in context what is this thing semiotic synthesis, and how and why it differs from semiotic analysis. We follow proposing the concept of a "semion", as both an(More)
In this paper we elaborate on the use of nonlinear functions in the adjustment of membership functions in fuzzy processing. Using such a nonlinear scheme, called nonlinear context adaptation, the knowledge can be encoded in a standard frame of reference, and have its meaning tuned to the situation by means of a nonlinear transformation. Due to its nonlinear(More)
In this paper, the authors describe the first steps of a semiotic-oriented software development process called "Brainmerge" [1], and present a case study where the process is used to coordinate the steps required for the design of a locomotive and car assignment system, modeled as an Intelligence Augmentation Systems (IAS). IAS represent an extension of(More)
