Abstract

fetched live from OpenAlex

Many emerging applications that use XML are distributed, usually over the Internet or over large Peer-to-Peer (P2P) networks. A fundamental problem of XML query processing in these systems is how to locate the data relevant to the queries so that only useful data are involved in query evaluation. In this paper, we address this problem within the context of structured P2P networks, and propose a novel data locating mechanism for query shipping systems. Our approach follows the multi-hop routing approach and encodes the hierarchical information of the XML data into the overlay network, so that routing keys can be hierarchical XML path expressions. We also propose a decentralized data locating algorithm that does not employ a centralized catalog but also avoids flooding the network with XML queries. We report comprehensive experiments to demonstrate the scalability and effectiveness of the data locating mechanism. 1

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.
