Abstract

fetched live from OpenAlex

The partitioning of RDF data on a large scale allows generating a set of RDF data subgraphs.METIS is a graph partitioning technique that minimises the cost of partitioning.METIS applies, among other things, to RDF graphs.However, the semantics introduced in the description of RDF data is not taken into account in the partitioning process in METIS.For this, we propose in this paper a step of pre-processing RDF data before partitioning these data.The objective of this step is to improve the quality of semantic partitioning of RDF graphs.The evaluation of the RDF pre-processing step for METIS was performed on real and synthetic data.

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.
