Execution infrastructure for normative virtual environments
Virtual Institutions (VIs) have proven to be adequate to engineer applications where participants can be humans and software agents. VIs combine Electronic Institutions (EIs) and 3D Virtual Worlds (VWs). In this context, Electronic Institutions are used to establish the regulations that structure interactions and support software agent participation while Virtual Worlds facilitate human participation. In this paper we propose Virtual Institution eXEcution Environment (VIXEE) as an innovative communication infrastructure for VIs. Using VIXEE to connect Virtual Worlds and EI opens EI to humans, providing a fully operational and comprehensive environment. The main features of the infrastructure are (i) the causal connection between Virtual Worlds and Electronic Institutions, (ii) the automatic generation and update of the VIs' 3D visualization and (iii) the simultaneous participation of users from different virtual world platforms. We illustrate the execution of VIXEE system in a simple eAuction house example and use this example to evaluate the performance of our solution
Towards next generation coordination infrastructures
Coordination infrastructures play a central role in the engineering of multiagent systems. Since the advent of agent technology, research on coordination infrastructures has produced a significant number of infrastructures with varying features. In this paper, we review the the state-of-the-art coordination infrastructures with the purpose of identifying open research challenges that next generation coordination infrastructures should address. Our analysis concludes that next generation coordination infrastructures must address a number of challenges: (i) to become socially aware, by facilitating human interaction within a MAS; (ii) to assist agents in their decision making by providing decision support that helps them reduce the scope of reasoning and facilitates the achievement of their goals; and (iii) to increase openness to support on-line, fully decentralised design and execution. Furthermore, we identify some promising approaches in the literature, together with the research issues worth investigating, to cope with such challenges. © Cambridge University Press, 2015.The work presented in this paper has been partially funded by projects EVE (TIN2009-14702-C02-01), AT (CSD2007-0022), and the Generalitat of Catalunya grant 2009-SGR-1434Peer Reviewe

Estudio y mejora de la usabilidad de un mundo virtual hÃbrido: interacción humano-agente
Treballs Finals de Grau d'Enginyeria Informà tica, Facultat de Matemà tiques, Universitat de Barcelona, Any: 2013, Director: Inmaculada Rodriguez Santiago i Pablo Almajano FrancoyNowadays, due to the increasing use of the Internet and the improvements in the field of 3D graphics virtual worlds have reached a
high popularity. A virtual world is a 3D simulation that features a real or imaginary world where the users, represented by avatars, interact with each other and the environment. These open 3D environments are
attractive for their immersiveness and the enjoyment they offer, as well as for the social aspect that they bring by joining multiple users together in a common environment and engaging them to participate together. Taking into account not only their popularity but the many practical uses a virtual world has, serious virtual worlds arise. Their aim is to regulate the behaviors in the virtual world in order to allow certain tasks to be done, which can be for example procedures related to e-Government or e-Learning. In this project we have conducted a usability study of v-mWater, a serious and hybrid (where both humans and bots interact) virtual world.
With the results that have been obtained from the study, we have implemented the most beneficial improvement of v-mWater, that has
consisted in using AIML to allow the bots of v-mWater to process natural language, turning them into conversational bots
Communicating open systems
Just as conventional institutions are organisational structures for coordinating the activities of multiple interacting individuals, electronic institutions provide a computational analogue for coordinating the activities of multiple interacting software agents. In this paper, we argue that open multi-agent systems can be effectively designed and implemented as electronic institutions, for which we provide a comprehensive computational model. More specifically, the paper provides an operational semantics for electronic institutions, specifying the essential data structures, the state representation and the key operations necessary to implement them. We specify the agent workflow structure that is the core component of such electronic institutions and particular instantiations of knowledge representation languages that support the institutional model. In so doing, we provide the first formal account of the electronic institution concept in a rigorous and unambiguous way
VIXEE an innovative communication infrastructure for virtual institutions
Virtual Institutions (VI) provide many interesting possibilities for social virtual environments, collaborative spaces and simulation environments. VIs combine Electronic Institutions and 3D Virtual Worlds. While Electronic Institutions are used to establish the regulations which structure participants interactions, Virtual Worlds are used to facilitate human participation. In this paper we propose Virtual Institution Execution Environment (VIXEE) as an innovative communication infrastructure for Virtual Institutions. Main features of the infrastructure are i) the causal connection between Virtual World and Electronic Institutions layers, ii) the automatic generation and update of VIs 3D visualization and iii) the simultaneous participation of users from different Virtual World platforms
