Abstract

fetched live from OpenAlex

SQL is a standard language used for defining, manipulating, and querying relational databases. This appendix provides a brief discussion of how basic queries conveyed in SQL may be expressed in LogiQL. Consider the following relational database, which includes two relational tables (Tables H.1 and H.2) describing countries in 2011. The country table lists the ISO two-letter code, name, and population of various countries. For discussion purposes, the population of Finland (5,396,292) is omitted simply to illustrate SQL’s use of a null value to indicate that a data value is missing (e.g., because it is unknown or inapplicable). To save space, only a small number of countries are included. For those countries that have presidents, the president table lists the name, country, gender, and birth year of those presidents. Australia, Canada, and the United Kingdom have prime ministers instead of presidents, so they are not included in the president table. Throughout the database, countries are standardly identified by their country codes. The entries in the first two columns of the tables are necessarily unique, so each of these columns is a candidate key for its table. The country table has countryCode as its primary key and countryName as an alternate key.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
