Abstract

fetched live from OpenAlex

Web map services, such as Google Maps and MapQuest, are among the most popular sites on the Internet. One can easily access these services through a Web browser on a personal computer or mobile device. The high accessibility and efficiency offered by these sites is possible, in part, by the use of standard image formats. The present review is a description of the most common image formats available from web map servers nowadays, as well as other formats with great possibilities for the future. We describe raster and vector formats and highlight advantages and disadvantages in each case. We also refer to protocols and image formats supported by the Open Geospatial Consortium (OGC) standards.

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.
