Abstract

fetched live from OpenAlex

In this paper, we describe a method for transforming and migrating data schemas developed for RDBMS to HBase. The method consists of a set of HBase-organization guidelines and a four-step data-schema transformation process that HBase application developers may follow during the migration of their application data from RDBMSs to HBase. The method also considers data-access paths extracted from query logs, in order to improve the quality of the transformation and the eventual access efficiency of the HBase repository. We illustrate and validate the method with a case study.

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.

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.
