Any scientific community relies on a shared set of concepts and methods that, when well established and known, can guide its members to better solving research problems. Actor-Network Theory states that human and non-human entities – such as scientific literature – work together when a scientific fact is constructed. We applied this viewpoint as social network analysis technique, to assess the bibliographical data from the last two ICISO proceedings. The resulting graphs highlighted persons and publications acting as points of convergence for each conference edition. These findings lead to a recurring structure cored on Ronald Stamper and his publications, and the book Semiotics in Information Systems Engineering.
