Efficiently mining crosscutting concerns through random walks
Bibliographic record
Abstract
Inspired by our past manual aspect mining experiences, this paper describes a random walk model to approximate how crosscutting concerns can be discovered in the absence of domain knowledge of the investigated application. Random walks are performed on the coupling graphs extracted from the program sources. The ideas underlying the popular page-rank algorithm are adapted and extended to generate ranks reflecting the degrees of "popularity" and "significance" for each of the program elements on the coupling graphs. Filtering techniques, exploiting both types of ranks, are applied to produce a final list of candidates representing crosscutting concerns. The resulting aspect mining algorithm is evaluated on numerous Java applications ranging from a small-scale drawing application, to a medium-sized middleware application, and to a largescale enterprise application server. In seconds, the aspect mining algorithm is able to produce results comparable to our prior manual mining efforts. The mining algorithm also proves effective in helping domain experts identify latent crosscutting concerns.

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; a candidate call from one teacher head, not a consensus.
