Abstract

fetched live from OpenAlex

This method describes a statistical procedure to compare a single mean to its JAR scale mid-point. It will determine if a product attribute is perceived to be significantly different from the ideal. When an attribute is significantly different from the mid-point, conclusions can also be made about the direction of the difference. This analysis is designed to compare a single product/attribute combination to its center-point, and is not appropriate for the comparisons across products or attributes. Comparisons among multiple products in the same test are limited to statements as to how they each relate to the JAR scale mid-point or “Ideal” value. Note that the “Ideal” value refers to the JAR scale mid-point, and is not related to a specific gold standard product.

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.
