In the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent. The ability to create intelligent machines has intrigued humans since ancient times and today with the advent of the computer and 50 years of research into various programming techniques, the dream of smart machines is becoming a reality. Researchers are creating systems ...

One of the problematic aspects of “complexity” is still its definition. We encounter many definitions and criteria for a system being complex from different points of view, some of which give rise to contradictory results: for a given system some definitions deduce that the system is complex, but others lead to the opposite result. An attempt is made to deal with the concept of complexity from ...

We recall the concept of a linguistic variable and the representation of its values (i.e. linguistic terms) by means of fuzzy sets. In this framework adverbs are represented by fuzzy modifiers, i.e. operators acting on these fuzzy sets. We investigate two important classes of popular fuzzy modifiers. Grounding on results from psycholinguistic research, we discuss their pro’s and contra’s for re...

in this paper, the problem of determining the quality level, lead time for order delivery and price of a product produced by a manufacturer is considered. in this problem the demand for the product is influenced by all three decision variables: price, lead time and quality level. to formulate the demand function, a fuzzy rule base that estimates the demand value based on the three decision vari...

The paper aims to expand the concept of linguistic variable. The study analyzes the common conclusion forms in the evaluation project. The evaluation often makes the final conclusion by analyzing the fuzzy number and its membership function. However, the information of modified word or phrase (“largely”, “preliminary” and “unclear”) has got lost in analysis. The research believe these modified ...

The fuzzy sets defining the linguistic variable values can be seen as a fuzzy partition of the linguistic variable. The membership functions obtained using fuzzy clustering algorithms are defined with respect to the group prototypes, and they cannot be used to define the linguistic variable values. We introduce several criteria to pass from the clustering membership functions to the linguistic ...

The role of linguistic context in the linguistic oriented fuzzy control is emphasized and methods for learning of the linguistic context are presented. The linguistic context of the independent variable is determined automatically whereas the linguistic context of the dependent variable is interpolated from known values .

Within the EU Framework V project VICTEC we develop a running model of empathy that is based on both empirical results and a state-of-the-art general psychological theory and can be implemented in virtual agents. Empathy focuses on the ability of one person (the so called “observer”) to perceive, to identify and to deal with the emotions of a social partner (whether virtual or human agent; “tar...

An approach based on relative optimal membership degree is proposed to deal with multiple attribute decisionmaking (MADM) problems under risk with weight information unknown and attribute value as linguistic variable. Firstly, the operational laws of linguistic variable are introduced, and risk linguistic decision matrix is transformed into certain linguistic decision matrix by expectation valu...
