Abstract
En 中文
• A new framework jointly models commit messages, code diffs, and changed semantics.
• Changed semantics capture added and deleted content identified from ASTs.
• CMD reduces reliance on commit messages during the training.
• The method remains robust when commit messages are missing.
• The method achieves leading performance on two public security patch datasets.
