Abstract

fetched live from OpenAlex

Indexing XML data is essential for XML query optimization. Most of the existing approaches that combine a labeling scheme with a path index use labeling schemes that reflect the structure of the indexed data. In addition, the labeling rules do not depend on the combined path indexes. By designing a labeling scheme that does not reflect the structure of XML data, since it is available in the accompanied path index; and by aligning the data nodes' labels with the path index nodes' labels, we can support the join process more efficiently. We propose a novel index structure called LTIX (Level-based Tree Index for XML databases). This index structure is based on Level-based Labeling Scheme (LLS) that not only minimizes the number of joins and matches required to evaluate twig queries, if it is used with path indexes, but also facilitates effective query optimization through early pruning of the space search. Experimental tests show the performance benefits of our proposed approach.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
