Abstract

fetched live from OpenAlex

Most approaches to knowledge discovery in databases consider extractions one at a time. However it is well known that, in practice, any extraction process is interactive and iterative. In this paper, we introduce an approach that can take benefit from previously computed extractions in the computation of the current extraction. To do so, we assume that the answers to previous extractions are stored and we use properties of query containment for pruning candidate queries. First, we introduce our approach in the context of deductive databases. Then, we show that restricting our framework to the case of relational queries allows for reducing the complexity of query containment tests. The experimental results reported in this paper show a significant reduction of computation time when taking into account the iterative aspects mentioned above.

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.
