Agents need an environment to operate and exist. Without the environment, agents are simply useless or never exist. Interaction is the act or process where agents communicate in a way to influence the behaviour or belief of other agents. Agents? interaction takes the form of coordination, cooperation, collaboration, negotiations, contracts, agreement, communication protocols, and speech acts. Agents? interaction in ubiquitous environment is generally characterized by 1) openness, describing the possibilities that these mobile entities can join or leave the environment, 2) flexibility indicating the degree the mobile entities are restricted by the environment rules and norms, 3) stability defining the predictability of the consequences of actions and 4) trustfulness specifying the extent to which users may trust the environment. Social aspects of multi-agents systems have received a lot of attention from the community since social ability is one of the most important attributes of agents which has opened up new modes of interaction and dynamic organizational configurations that were previously inconceivable within a wide array of human and business activities. In this talk, I will elaborate on how agents interactions can be modelled using norms which are interpreted in different contexts and understood to mean a standard expectation about what behaviour, thoughts, or feelings are appropriate within a given group (of agents) within a given context (i.e., location, time, environment) and show how agents should behave based on established protocols, rules of conduct or accepted social practices.
