Abstract

fetched live from OpenAlex

The Dorset cultures lived in the Canadian Arctic and Greenland around two thousand years ago (800 BC – AD 1300). Despite their relatively long time period and large geographic span, it has always been noted that collections of Dorset artefacts are “remarkably uniform” in contrast to other Arctic cultures. This has then led to further theoretical assumptions, for example that there was a high level of information and object exchange across the entire Dorset span. However, this is because Arctic archaeologists have mainly classified the objects based on superficial characteristics such as shape, style, and form (otherwise known as the typology). Microwear analysis is a scientific method that allows archaeologists to see microscopic traces showing how objects were made and used. By using this method, we can understand not just the finished objects themselves (which is the main focus of methods which look only at typology), but also the people who interacted with them. For example, we can learn about the choices made during the steps of manufacture, or the various ways in which different people used the same object type. This PhD project therefore challenges the assumption of “uniformity” of Dorset artefacts by using microwear analysis to look at them in new ways. Using this method, we can then gain further insight into how Dorset groups interacted with their material world.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
