Nowadays the society has demanded a school that offers a qualitative and up-to-date teaching. So, it is necessary that teachers have an education that leads them to know the educational potentialities of computers. This education requires, from the universities, courses that leave the idea of copying contents and doing tests. It is necessary that t...

This paper presents an agent negotiation model for ontology mapping. We consider that different agents working on the basis of particular approaches arrive to distinct mapping results that must be shared, compared, chosen and agreed. Then, the final mapping result must reflect a better solution than individual approaches.

The area of animated interface agents is related to the development of applications that aim to improve human-computer interaction process using software agents represented by characters or human figures. Although several projects are being developed in this area, there isn't a method to describe criteria that ought to be considered to evaluate ani...

Well-known approaches for the ontology mapping can be grouped into lexical, semantic, and structural ones. We assume that the approaches are complementary to each other and their combination produces better results than the individual ones. However, they produce difierent and probably con∞icting results, which must be shared, compared, chosen and a...

Coordination is an important characteristic in the development of agents organizations, allowing agents to understand the existent relationships among agents that compose an specific organization. This paper proposes an improvisational multi-agent organization which incorporate a new model of coordination, named improvised direction. The organizati...

Nowadays there is some confusion around the terms used to conceptualize multiagent coordination mechanisms. We understand that the characterizations in coordination mechanisms mix two distinctive aspects of coordination: the result of coordination and the behavioral mode that agents use to accomplish a given result of coordination. In this paper, w...

I.-INTRODUCTION: Most of the research within the field of interactive characters has concentrated on generating guidelines, or models, for believable individual variability among characters, often based on psychological personality models (such as Nass, Isbister and Lee, 2000), or biological behaviors (for example, see Blumberg, 1994). In contrast,...
