Abstract

fetched live from OpenAlex

This paper presents recent developments of an indexing technique aimed at improving parsing times. Although several methods exist today that serve this purpose, most of them rely on statistical data collected during lengthy training phases. Our goal is to obtain a reliable method that exhibits an optimal efficiency/cost ratio, without lengthy training processes. We focus here on static analysis of the grammar, a method that has unworthily received less attention in the last few years in computational linguistics. The paper is organized as follows: first, the parsing and indexing problem are introduced, followed by a description of the general indexing strategy for chart parsing; second, a detailed overview and performance analysis of the indexing technique used for typed-feature structure grammars is presented; finally, conclusions and future work are outlined.

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.
