Abstract: The present study belongs to the new research direction that aims to improve software defect prediction by using additional knowledge such as source code comments. The fusion of programming language features learned from the code and natural language features extracted from the code comments is the proposed semantic representation of a source code. Two types of language models are applied to learn the semantic features: (1) the pre-trained models CodeBERT and RoBERTa for code embedding and textual embedding; (2) doc2vec model used for both, code embedding and comments embedding. These two semantic representations, in two combinations (only code features and code features fused with comment features), are used separately with the XGBoost classifier in the experiments conducted on the Calcite dataset. The results show that the addition of the natural language features from the comments increases the software defect prediction performance.
