Abstract

fetched live from OpenAlex

Currently the Higher Education Institutions use of academic management systems and the data generated by these transactional systems has not been effectively exploited. The objective of this research is to present a Data Warehouse approach for these institutions, in order to support decision making by educational managers. The approach is generic and can be applied to a wide range of Educational Institutions. We present a case study applied at the XXXX. The proposal is based on the use of materialized views to build the Data Warehouse and the use of table functions for aggregation of business rules.

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.
