Abstract

fetched live from OpenAlex

The need to accurately classify records is a core problem in many domains. Current methods for auto-classification focus on a record's content and not its context. As a result, current auto-classification methods are unable to achieve the levels of precision, accuracy, and recall that match or exceed the levels generated by human classifiers. In order to address this challenge, a new methodology is needed that specifies how to extract contextual features from a record in order to improve the auto-classification accuracy, precision, and recall of records at scale. This paper closes this gap, using the diplomatic definition of context to specify a mapping that will operationalize the capturing of context from a record. This mapping, makes it possible to continue developing a formal method for functional auto-classification and contextual feature extraction that will utilize a record's context to improve functional auto-classification accuracy, precision, and recall.

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.
