Abstract

fetched live from OpenAlex

World financial markets also went through a gut-wrenching financial decline in October of 1987. Sometimes called Black Monday, stocks began to trade steeply downward, first in Asian markets, then in Europe and Africa, and finally in the Americas. When trading was over at the end of that day, New Zealand’s market fell by almost 60%; Australia’s and Hong Kong’s fell off by more than 40%, and markets in Europe, Canada, and the United States were down by between 20% and 35%. The drop in the Dow Jones Industrial Average at 22.6%, represents the largest plunge in its history. Some argue that it was technology that led the markets down. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

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.
