Abstract

By questioning the past, archaeological information is naturally prone to imperfection. Through a series of examples, we will briefly present its various aspects (inaccuracy, uncertainty, vagueness, conflict, lack) which can apply to time, space and function. The first stage consists in the identification, characterization and recording of imperfection in the archaeological information system. At the second stage, the question arises of how the imperfection of knowledge in archaeological hypotheses should be taken into account in terms of analysis, production and restitution. In the SIGRem project, we have chosen to resort to the Fuzzy sets theory. At a final stage, although the promotion through the media of results can nowadays be carried out by a 3D modeling, realistic reconstruct being very often confusingly perceived as truth, we tend to lose the richness of confidence levels we have in our knowledge. Therefore, we will also describe how visual paradigms can be used to enable dynamic perception of uncertainty in dedicated 3D virtual environments.
