Agent
Categories: Disambiguation pages in need of cleanup | Disambiguation
An agent is an autonomous entity with an ontological commitment1 and agenda of its own. The term originated in philosophy. Each agent possesses the ability to act autonomously; this is an important distinction because a simple act of obedience to a command does not qualify an entity as an agent. Nevertheless in business and in law an agent is often acting on a principal's behalf and has a legal duty to act in that person's best interest. An agent may interact1 or negotiate with its environment and/or with other agents. It may make decisions, such as whether to trust and whether to cooperate with others.
The term agent is often used in various areas to mean specific people or items:
