Formally defining the time-space-archaeological culture relation: problems and prospects

Abstract

Locating archaeological cultures in time and space is a major challenge of archaeolog- ical research. Despite more than a century of scientific research in archaeology, a satisfactory solution has yet to be proposed. Past attempts to look into the problem focused on sharpening the definition of types of material culture artefacts, a more accurate chronological dating of such objects, various probabilistic methods or GIS solution for defining the time-space borders of archaeological cultures. However, the proposed approaches did not fully consider how the nature of archaeological cultures and their consequent dating and geographic positioning play a crucial role in assigning spatio-temporal borders. We propose to shift the operating logical paradigm in archaeology, from a crisp, Aristotelian-based logic, to fuzzy logic, in our opinion more suitable for reasoning in archaeology. We also introduce the rough sets theory to deal with chronological and geographic positioning of archaeological cultures. Both concepts have, in our opinion, substantial advantages over the traditional algebra and logic rules (implicitly) applied so far.
