Along with the continuously growing volume of information resources, there is a growing interest toward better solutions for finding, filtering and organizing these resources. Automatic text categorization can play an important role in a wide variety of flexible, dynamic, and personalized information management tasks. The aim of this research work is to make use of concepts as a way of improvin...

The evolution of color categorization systems is investigated by simulating categorization games played by a population of artificial agents. The constraints placed on individual agent’s perception and cognition are minimal and involve limited color discriminability and learning through reinforcement. The main dynamic mechanism for population evolution is pragmatic in nature: There is a pragmat...

A dynamic interactive theory of person construal is proposed. It assumes that the perception of other people is accomplished by a dynamical system involving continuous interaction between social categories, stereotypes, high-level cognitive states, and the low-level processing of facial, vocal, and bodily cues. This system permits lower-level sensory perception and higher-order social cognition...
