Abstract

fetched live from OpenAlex

In recent decades there has been an extraordinary growth in and acceptance of automatic data systems that collect official and popular reports of epidemic occurrence. While different systems employ one or another proprietary algorithms to collect and parse disease reports all include, at a minimum, spatial locators, the date of a report, and the number of individual cases reported. These systems have been increasingly vital in both the study of individual epidemics and the exposition of expanding epidemics in real time. To date, however, there has been little analysis of the nature and quality of the data collected in these “big-net” programs or the degree to which redundancies and uncertainties may limit their utility. Here data on the 2009 H1N1 Type-A influenza epidemic gathered by a single system, healthmap.org, is parsed to determine where problems exist and how they might be rectified.

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.
