Three-way model differencing and conflict detection
Bibliographic record
Abstract
We have further enhanced our practice, DSMCompare, to detect semantic differences and conflicts based on a three-way domain-specific comparison approach. To evaluate our practice, using a novel technique; we first used a reverse engineering method to transform the minimal collection of conflicting files of source codes involved in each commit into a three model for 95 conflicting commits over 13 open source GitHub projects and then calculated a high precision and recall compared to RefConfMiner's result. The repository contains the results of the evaluation including the common ancestor model, left version mode, right version model, and the results of semantic comparison and conflict detection for each commit. The source code and relevant artifacts such as meta-models are available at: https://github.com/geodes-sms/DSMCompare/
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
