Abstract

fetched live from OpenAlex

On the one hand, the lack of structure of Peer-to-Peer (P2P) networks is key to their robustness and accessibility. On the other hand, this same lack of structure creates difficulties in efficiently searching the contents of the network. This search problem must be addressed for P2P networks to grow beyond the world of file sharing. To this end, we present a novel approach for describing the documents accessible through peers as a taxonomy. We propose a scoring function which is used to route queries within the network based on such taxonomical information, as well as the number of results desired by the query. The scoring function aims to minimize the number of network messages required to answer a query. When comparing to a sequential query forwarding algorithm, our simulations have shown that our proposed technique is able to reduce the number of messages generated for a query by a factor of 10. Also, our experiments show that limiting the “time to live ” of a query is likely to make queries more expensive. 1

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.
