Abstract

fetched live from OpenAlex

When a developer works on code that is shared with other developers, she needs to know why the code has been changed in particular ways to avoid reintroducing bugs. A developer looking at a code change may have access to a short commit message or a link to a bug report which may provide detailed information about how the code changed but which often lacks information about what motivated the change. This motivational information can sometimes be found by piecing together information from a set of relevant project documents, but few developers have the time to find and read the right documentation. We propose the use of multi-document summarization techniques to generate a concise natural language description of why code changed so that a developer can choose the right course of action.

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.

Not 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.
