Abstract

fetched live from OpenAlex

Suppose you are a business analyst and you need to find the customer purchase records of a certain market in the last quarter from 1.3 million tables and billions of records to make a predictive analysis of the consumption trend in this region for the next quarter. How are you going to do it? This task is like looking for a needle in a haystack. What is even more frustrating is that when you finally find the relevant data after spending weeks on source data exploration, it is out of date, and new essential data is available. This example illustrates that it is not sufficient for companies to make data accessible; they also need to make it discoverable, understandable, and consumable in near real time to gain timely and relevant insights from the data.

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.
