Agents in the societies can be either human agents or artificial agents. The focus of my present and past research is both on: (i) the present society in which human agents interact with the support of ICT through social networks and media, and (ii) future society with mixed interactions between human agents and artificial systems such a sautonomous agents and robots. Indeed, new technologies will come for future society in which such artificial systems will play a major role, so that humans will necessarily interact with them in their daily lifes. This includes autonomous cars and other vehicles, robotic assistants for rehabilitation and for the elderly, robotic companions for learning support.The general aim of my research is to provide formal models of social interaction between cognitive agents. I have mainly worked in the area of artificial intelligence(AI) with strong interaction with other disciplines such as economics, philosophy and cognitive sciences. There are two main general observations under lying my research project. The first is that interaction plays a fundamental role in existing information and communication technologies (ICT) and applications (e.g., Facebook, Ebay, peer-to-peer systems) and will become even more fundamental in future ICT. The second is that the cognitive aspect is crucial for the design of intelligent systems that are expected to interact with human agents (e.g., embodied conversational agents, robotic assistants, etc.). In these situations the system must be endowed with a psychologically plausible model of human reasoning and human cognition in order to be able to understand the human agent’s needs and to predict her behaviour.
