Abstract

fetched live from OpenAlex

The Portuguese Settecento (18th century) constitutes a unique moment in the history of Portuguese collecting, especially for art galleries art in Lisbon. The art galleries of the Portuguese Royal House, the nobility (lords), and the ennobled bourgeoisie (in the last quarter of the 18th century) were endowed with paintings by excellent artists, some of whom represent the most emblematic periods in the history of national and European art. The works contained within these art galleries still fetch astronomical prices on the international art markets today. However, many of these collections have disappeared, due to various factors, ranging from natural disasters to the French invasions and the decline and fall of the families that owned them, and leading to the dispersion of a heritage representing a crucial legacy of Portuguese museum culture.

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.

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.
