Abstract

fetched live from OpenAlex

A random sample of 628 Web pages registered with Yahoo! was analyzed for use of META tags and specifically the DESCRIPTION tag; 357 contained META tags and 163 used the DESCRIPTION tag. Some of the descriptions greatly exceeded typical length guidelines of 150 or 200 characters. A minority duplicated exactly phrasing found in the visible text; most repeated some words and phrases. Noun phrases were slightly more common than complete sentences. Content usually related to responsible corporate bodies and their products and services; information about the page or site itself was included in about one-third of descriptions.

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.
