Abstract

To address the semantic consistency problem of migrated code in the source code migration model, this paper introduced the statement-level attention mechanism based on the token-level attention mechanism, proposed a source code migration model HPGN based on the hierarchical attention mechanism, and designed state feeding mechanisms. During migration, the statement-level attention mechanism aligned the features of source code statements and migrated code statements, the tokenlevel attention mechanism extracted tokens from the aligned code statements, and the state feeding mechanism passed the feature of adjacent migrated code statement, thus improving the semantic consistency of migrated code. Experimenting on a real project dataset, the results show that HPGN improves the overall score by 3.4 over the best comparison model while having fewer model parameters. In addition, ablation experiments validate the effectiveness of the state feeding mechanisms and HPGN hierarchical architecture.
