Abstract

fetched live from OpenAlex

Datasets with a heavy-tailed histogram tend to have a large number of outliers, which provide important information. As a result, the bulk part and tail part of the dataset with this feature have different characteristics. Then, the choice of a threshold that separates these two parts is important. We propose a novel approach based on the Empirical Likelihood method to estimate this threshold. Because the transition between the bulk and tail parts cannot be fully disjointed in many cases, we allow the threshold to be a random variable instead of a fixed number. In addition, the threshold is relative to a benchmark since heaviness is a relative concept.

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.
