    Original article can be found at: http://www.igi-global.com/articles/details.asp?ID=35052 Copyright IGI. Posted by permission of the publisher.This article presents research towards the development of a virtual learning environment (VLE) inhabited by intelligent virtual agents (IVAs) and modeling a scenario of inter-cultural interactions. The ultimate aim of this VLE is to allow users to reflect upon and learn about intercultural communication and collaboration. Rather than predefining the interactions among the virtual agents and scripting the possible interactions afforded by this environment, we pursue a bottomup approach whereby inter-cultural communication emerges from interactions with and among autonomous agents and the user(s). The intelligent virtual agents that are inhabiting this environment are expected to be able to broaden their knowledge about the world and other agents, which may be of different cultural backgrounds, through interactions. This work is part of a collaborative effort within a European research project called eCIRCUS. Specifically, this article focuses on our continuing research concerned with emotional knowledge learning in autobiographic social agents.Peer reviewe

    Learning behavior in abstract memory schemes for dynamic optimization problems

    This is the post-print version of this article. The official article can be accessed from the link below - Copyright @ 2009 Springer VerlagIntegrating memory into evolutionary algorithms is one major approach to enhance their performance in dynamic environments. An abstract memory scheme has been recently developed for evolutionary algorithms in dynamic environments, where the abstraction of good solutions is stored in the memory instead of good solutions themselves to improve future problem solving. This paper further investigates this abstract memory with a focus on understanding the relationship between learning and memory, which is an important but poorly studied issue for evolutionary algorithms in dynamic environments. The experimental study shows that the abstract memory scheme enables learning processes and hence efficiently improves the performance of evolutionary algorithms in dynamic environments.The work by S.

    Modelling cultural dimensions and social relationships to create cultural synthetic characters

    The work presented in this thesis investigates studies and theories of culture, social power and the relationship between culture and emotion studied by psychologists and anthropology. We operationalised a Cultural Dimension model, proposed by Hofstede, and Social Power and integrated them into an already existing architecture for autonomous agents called “FAtiMA”. The purpose of the adapted system is to generate culturally-specific behaviour in character interaction which is recognisably different to users. Two different experiments, with human participants, were conducted to investigate the perceived differences between two different groups of characters: with and without cultural parameters. The main result shows that users do recognise the differences in character behaviour between the two experimental cases, which demonstrates that our model is able to create culturally-specific synthetic characters

    Player agency in interactive narrative: audience, actor & author

    Get PDF
    The question motivating this review paper is, how can computer-based interactive narrative be used as a constructivist learn- ing activity? The paper proposes that player agency can be used to link interactive narrative to learner agency in constructivist theory, and to classify approaches to interactive narrative. The traditional question driving research in interactive narrative is, ‘how can an in- teractive narrative deal with a high degree of player agency, while maintaining a coherent and well-formed narrative?’ This question derives from an Aristotelian approach to interactive narrative that, as the question shows, is inherently antagonistic to player agency. Within this approach, player agency must be restricted and manip- ulated to maintain the narrative. Two alternative approaches based on Brecht’s Epic Theatre and Boal’s Theatre of the Oppressed are reviewed. If a Boalian approach to interactive narrative is taken the conflict between narrative and player agency dissolves. The question that emerges from this approach is quite different from the traditional question above, and presents a more useful approach to applying in- teractive narrative as a constructivist learning activity

    Standard model of the mind and perceptual control theory : a theoretical comparison between two layouts for cognitive architectures

    Get PDF
    Research on artificial intelligence (AI) has often focused on techniques for implementing specialized aspects of intelligence without regard for the full picture of intelligence and cognition. However, a need for more general, human-like AI systems has also been recognized. In this thesis, our aim was to study potential starting points for a comprehensive, general and truly human-like cognitive architecture. We performed a comparative theoretical analysis on two existing layouts, the standard model of the mind and perceptual control theory (PCT), based on functional criteria gathered from literature. While our results indicate that the PCT model is more comprehensive than the standard model on a theoretical level, finding out the true benefits and challenges of the models and their suitability as foundations for human-like AI systems requires practical evaluation. Additional research is needed to fill current gaps in both models, create their computational implementations, and design practical evaluation methods suitable for them
