Abstract

fetched live from OpenAlex

Query processing strategies for ranked retrieval have been studied for decades. In this paper we propose a new strategy, which we call rank-at-a-time query processing, that evaluates documents in descending order of quantized scores and is able to directly compute the final document ranking via a sequence of boolean intersections. We show that such a strategy is equivalent to a second-order restricted composition of per-term scores. Rank-at-a-time query processing has the advantage that it is anytime score-safe, which means that the retrieval algorithm can self-adapt to produce an exact ranking given an arbitrary latency constraint. Due to the combinatorial nature of compositions, however, a naive implementation is too slow to be of practical use. To address this issue, we introduce a hybrid variant that is able to reduce query latency to a point that is on par with state-of-the-art retrieval engines.

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.
