Abstract

fetched live from OpenAlex

We consider the problem of searching for a data element in a tree-structured data set (e.g., XML). We propose a method which is more efficient than tree traversal and which still retains all the important metadata information that would be lost in the naive method of linear list search. We compute a bloom filter for each interior node of the tree, essentially building a bloom filter tree to enhance the original data tree. Using the bloom filters, we can do fast search by pruning out entire subtrees from being searched. We present a theoretical analysis of the search complexity of selective placement of bloom filters in the tree, which leads to an optimal placement strategy. Our experiments verify the efficiency of our method.

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.
