Abstract
"Evaluation as a service" (EaaS) refers to a family of related evaluation methodologies that enables community-wide evaluations and the construction of test collections on documents that cannot be easily distributed. In the API-based approach, the basic idea is that evaluation organizers provide a service API through which the evaluation task can be completed, without providing access to the raw collection. One concern with this evaluation approach is that the API introduces biases and limits the diversity of techniques that can be brought to bear on the problem. In this paper, we tackle the question of API bias using the concept of retrievability. The raw data for our analyses come from a naturally-occurring experiment where we observed the same groups completing the same task with the API and also with access to the raw collection. We find that the retrievability bias of runs generated in both cases are comparable. Moreover, the fraction of relevant tweets retrieved through the API by the participating groups is at least as high as when they had access to the raw collection.

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.
