Abstract

fetched live from OpenAlex

In a Peer Data Management System (PDMS), autonomous peers share semantically rich data. For queries to be translated across peers, a peer must provide a mapping to other peers in the PDMS; peers connected by such mappings are called acquaintances. To maximize PDMS query answering performance, a peer needs to optimize its choice of acquaintances. This paper investigates the acquaintance selection problem and introduces a novel framework for performing this acquaintance selection. Our framework includes two selection schemes that effectively and efficiently estimate mapping effectiveness. The "one-shot" scheme clusters peers and estimates the improvement in query answering based on cluster properties. The "two-hop" scheme estimates using locally available information at multiple rounds. Our empirical study shows that both schemes effectively help acquaintance selection and scale to large PDMSs.

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.
