Can we evaluate the quality of software engineering experiments?
Bibliographic record
Abstract
Context: The authors wanted to assess whether the quality of published human-centric software engineering experiments was improving. This required a reliable means of assessing the quality of such experiments. Aims: The aims of the study were to confirm the usability of a quality evaluation checklist, determine how many reviewers were needed per paper that reports an experiment, and specify an appropriate process for evaluating quality. Method: With eight reviewers and four papers describing human-centric software engineering experiments, we used a quality checklist with nine questions. We conducted the study in two parts: the first was based on individual assessments and the second on collaborative evaluations. Results: The inter-rater reliability was poor for individual assessments but much better for joint evaluations. Four reviewers working in two pairs with discussion were more reliable than eight reviewers with no discussion. The sum of the nine criteria was more reliable than individual questions or a simple overall assessment. Conclusions: If quality evaluation is critical, more than two reviewers are required and a round of discussion is necessary. We advise using quality criteria and basing the final assessment on the sum of the aggregated criteria. The restricted number of papers used and the relatively extensive expertise of the reviewers limit our results. In addition, the results of the second part of the study could have been affected by removing a time restriction on the review as well as the consultation process.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
