Abstract

fetched live from OpenAlex

Abstract We see the world in terms of the human experience. It is always changing. Neither the quality nor the quantity of human life is a constant. In the fourteenth century, when the world had about 450 million in-habitants, a quarter of the people of Europe were wiped out by the bubonic plague. The future must have seemed bleak to survivors. Two hundred years later, Elizabethan literature flourished, European explorers had discovered the New World, and population had inched up to 550 million. Until the advent of disease prevention, high death rates kept the population growth rate in check. Over the centuries, smallpox alone took hundreds of millions of lives, but by the eighteenth century, with the emergence of science during the Enlightment, medical advances such as Jenner’s vaccine and the germ theory of disease led to lower death rates and faster growth of population numbers.

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.
