Abstract

fetched live from OpenAlex

Text retrieval systems which store extremely large amounts of text while providing a multiuser retrieval service for a large customer base are discussed. Due to the severe I/O demands of such a system, it is usually beneficial, if not necessary to utilize a multiprocessor system with multiple I/O facilities in an effort to increase the parallel I/O activity, the objective being to lower search response times. The problem is defined, a solution is modeled and it is shown that the application can be handled in a very effective fashion by a multiprocessor system with a simple LAN-based topology. A type of functional splitting which, if done in a careful manner, helps improve search response time is described.>

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.
