Abstract

fetched live from OpenAlex

This paper explores the integration of confidential microdata between two National Statistics Agencies (NSOs) where a unique identifier is missing. Using mock data on international trade between these two countries, we use a cloud based secure enclave to integrate both NSOs’ trade data at the transaction level. Particular attention is given to ensuring input and output privacy, while maintaining the flexibility to produce both summary statistics on the linked data as well as econometric analyses that can lead to novel insights. As such, this study provides valuable insights into the potential of privacy enhancing techniques, in particular secure enclaves and differential privacy techniques, to improve data privacy while preserving the utility of the statistical results.

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.
