How Discovery Systems Use DataCite Metadata: Harvester Roundtable
Bibliographic record
Abstract
In this session, we will provide an overview of some of the cutting edge tools and services available for working with DataCite metadata, including our APIs, DataCite Commons, the public data file, and beyond. Alongside this, we will hear from some of the key players who are leveraging DataCite’s 50+ million metadata records to develop innovative tools for locating research. This will be an opportunity to learn about how DataCite metadata is and can be used, to enable discovery and reuse, and the impact that rich metadata can have on the scholarly record.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
