Exporting Institutional Repository Metadata as Dataset
Bibliographic record
Abstract
As a research institution an important part of our work is in making our scientific output available to the world. We currently have a very successful insitutional repository (IR), where is possible to find most of our work, like articles, thesis, posters, etc. Although very useful and active, the repository is geared towards human consuption, like PDF documents. But increasingly the consumer of the scientific output are AI/ML models in the form of data sets. We started a project to make the content of our repository available (DSpace) as a data set in CSV format. This project is part of another project to export the content of the repository to Preservica, and in this process we download the content and the metadata. We extract the metadata from the JSON file, and convert to an entry to the CSV file. The goal is to make our repository available for data scientists and AI engineers to explore the scientific production of the university.
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 machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
