Actor-network theory (ANT) evolved from the work of Michel Callon (1991) and Bruno Latour (1992) at the Ecole des Mines in Paris. Their analysis of a set of negotiations describes the progressive constitution of a network in which both human and non-human actors assume identities according to prevailing strategies of interaction. Actors' identities and qualities are defined during negotiations between representatives of human and non-human actants. In this perspective, "representation" is understood in its political dimension, as a process of delegation. The most important of these negotiations is "translation," a multifaceted interaction in which actors (1) construct common definitions and meanings, (2) define representativities, and (3) co-opt each other in the pursuit of individual and collective objectives. In the actor-network theory , both actors and actants share the scene in the reconstruction of the network of interactions leading to the stabilization of the system. But the crucial difference between them is that only actors are able to put actants in circulation in the system
