• An automatic multi-agent web image and associated keywords retrieval system 

      Papadakis, N.; Ntalianis, K.; Doulamis, A.; Stamoulis, G. (2009)
      Web-based image search engines and CBIR techniques are blind to the actual content. As a result querying for a specific object is often cluttered with irrelevant data, leading to low precision. Furthermore recall rates are ...
    • Collaborative agent-based detection of DDoS IoT botnets 

      Giachoudis N., Damiris G.-P., Theodoridis G., Spathoulas G. (2019)
      The Internet of Things constitutes the latest paradigm shift in computing. Billions of devices sense the real world and store produced data in the cloud. Existing security models, approaches and solutions are not able to ...
    • How can agents know what to assume when? 

      Giannikis, G. K.; Daskalopulu, A. (2008)
      The work in this paper is motivated from the need for assumption-based reasoning in normative systems, where, realistically, agents will have incomplete knowledge about their environment, and about other agents. The question ...
    • II-learn—a novel metric for measuring the intelligence increase and evolution of artificial learning systems 

      Iantovics L.B., Iakovidis D.K., Nechita E. (2019)
      A novel accurate and robust metric called II-Learn for measuring the increase of intelligence of a system after a learning process is proposed. We define evolving learning systems, as systems that are able to make at least ...
    • Indoor Visual Exploration with Multi-Rotor Aerial Robotic Vehicles 

      Rousseas P., Karras G.C., Bechlioulis C.P., Kyriakopoulos K.J. (2022)
      In this work, we develop a reactive algorithm for autonomous exploration of indoor, unknown environments for multiple autonomous multi-rotor robots. The novelty of our approach rests on a two-level control architecture ...
    • The representation of e-contracts as default theories 

      Giannikis, G. K.; Daskalopulu, A. (2007)
      It is widely acknowledged that a temporal representation of e-contracts is essential in order to support e-contract execution and performance monitoring. One possibility that has been explored by many researchers is to ...
    • The role of assumption identification in autonomous agent reasoning 

      Giannikis, G. K.; Daskalopulu, A. (2009)
      The concept of autonomy is central to the notion of agenthood and has been addressed by many researchers in the multi-agent systems community. We argue that the degree to which an agent's reasoning is autonomous is affected ...
    • A role-based infrastructure for customised agent system development in supply networks 

      Hämmerle, A.; Karageorgos, A.; Pirker, M.; Reitbauer, A.; Weichhart, G. (2004)
      This paper presents a methodology for generic role identification and role reuse together with an infrastructure enabling rapid development of role-based multi-agent system (MAS) applications. The infrastructure includes ...
    • Self-organization in multi-agent systems 

      Di Marzo Serugendo, G.; Gleizes, M. P.; Karageorgos, A. (2005)
      This paper is the synthesis of joint work realised in a technical forum group within the AgentLink III NoE framework, which elaborated on issues concerning self-organization and emergence in multi-agent systems (MAS). The ...
    • Towards a dynamic multi-agent based scaffolding framework 

      Papazoglou P., Psycharis S., Kalovrektis K. (2020)
      Students have different abilities, skills and background and thus the corresponding learning process is different. Moreover, the teacher strategy, the available equipment, etc, play a crucial role in the learning curve. ...
    • Towards dynamic and cooperative multi-device personal computing 

      Lalis, S.; Savidis, A.; Karypidis, A.; Gutknecht, J.; Stephanides, C. (2007)
      In the 2WEAR project we have explored the paradigm of cooperative multi-device personal computing, where different wearable, portable and infrastructure elements communicate with each other in an ad-hoc fashion. The physical ...
