Measuring the quality of design pattern detection results
Bibliographic record
Abstract
Detecting design patterns in large software systems is a common reverse engineering task that can help the comprehension process of the system's design. While several design pattern detection tools presented in the literature are capable of detecting design patterns automatically, evaluating these detection results is usually done in a manual and subjective fashion. Differences in design pattern definitions, as well as pattern instance counting and presenting, exacerbate the difficulty of evaluating design pattern detection results. In this paper, we present a novel approach to evaluating and comparing design pattern detection results. Our approach, called MoRe, introduces a novel way to present design pattern instances in a uniform fashion. Based on this characterization of design pattern instances, we propose four measures for design pattern detection evaluation that convey a concise assessment of the quality of the results produced by a given detection method. We have implemented these measures, and present case studies that showcase their usefulness.

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.
