Abstract

fetched live from OpenAlex

The Internet is now the main source of information. Most human activities take spatial information into account, and spatial data over the web are prominent in our daily life. We look at spatial data when we want to know about weather conditions and forecasts, for travel directions when we are heading off on vacation, or for a better grasp of online news that can be mapped, for example, a map of average family income per county. Because geographic data are big, and users dislike waiting to see a weather map or a travel route, specific data structures for efficiently transferring spatial data have been developed. These data structures are implemented as web data formats in which the geographic data can be “stored, sorted and packed.” Examples of such formats include GML, KML, GeoJSON, GeoRSS, and so on, and web data service standards such as WMS, WCS and WFS.

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.
