A New Method Using Graph and Lattice Theory to Discover Spatially Cohesive Sets of Artifacts and Areas of Organized Activity in Archaeological Sites
Michael Merrill, Dwight Read · American Antiquity · 2010
We propose a new method to analyze spatially cohesive sets of artifacts and relate them to intrasite activity areas using the spatial similarity and cohesion of artifact types. This method can handle heterogeneous data and is able to reveal and deconstruct overlapping areas into their constituent elements. Application to a Mousterian habitation site from the Levant as a case study enables us to distinguish three spatially cohesive yet overlapping sets ("tool kits") of artifact and ecofact types within the boundaries of an excavated 50 m² sub-area of the site.
