MMF3: Neural Code Summarization Based on Multi-Modal Fine-Grained Feature Fusion [article]

Zheng Ma, Yuexiu Gao, Lei Lyu, Chen Lyu
2022 arXiv   pre-print
Aims: This study intends to improve the model's prediction performance for high-quality code summarization by accurately aligning and fully fusing semantic and syntactic structure information of source  ...  They generally represent different modalities of a piece of code, such as an Abstract Syntax Tree (AST) and a token sequence, as two embeddings and then fuse the two ones at the AST/code levels.  ...  The reason is that both MMTrans and AST-Trans only explore the structural information of the AST modality of the source code and do not consider the information of the Token modality of the source code  ...
