Abstract

fetched live from OpenAlex

Graph databases have become increasingly important with the rise of social networks, and with the growth of the Semantic Web and characterization of biological networks. Regular path queries (RPQs) are a way to explore path patterns in graphs which have become a standard method to explore graph databases. SPARQL 1.1 includes property paths, and so now encompasses RPQs as a fragment. In many environments, such as visual query systems (VQSs), the RPQs are generated visually which may contain many commonalities that can be optimized globally. We introduce SWARMGUIDE, a framework for optimizing multiple regular path queries. The framework detects commonalities among the RPQs, in order to find an execution plan that is globally optimized over the plan spaces of the constituent RPQs.

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.
