Abstract

fetched live from OpenAlex

The Allen-Unger Database contains price series for commodities from locations in Europe from the late Middle Ages to 1914 and also from cities in the Americas, the Middle East and the Far East. It is also possible to search for series by date range, location and commodity or any combination of the three. Data are reported in Excel spreadsheets with the files downloadable. The Database serves as a useful tool for various forms of research in economic history and in social history with the information presented in an easily accessible and flexible format. The data are available at three different sites, each with its own unique features and advantages.

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.

Teacher imitation

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.
