Abstract

fetched live from OpenAlex

The use of historical cartography within a GIS environment to realize long-term change-detection studies of a certain area has become an established and fairly generalized practice. As is well known, the prerequisite condition for such analyses is the thorough rectification of the historical map's digital format. This article offers a methodology for creating a form of “accuracy assessment” for georeferencing executed on a historical map, based on a comprehensible control procedure that can be completed within a reasonable time frame. The fundamental idea is to use a set number of points to measure the gap between their positions on a georeferenced historical map and the reality of the territory. The control procedure creates a series of parameters to be added as metadata on the georeferenced map, constituted by the mean error distance and consequent standard deviation and by the percentage of an area examined on a map, drawn from a control grid superimposed on it.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
