Compilation Success Rate is an important evaluation metric in the natural language processing field for code translation / cross-lingual transfer tasks. It measures the proportion of translated code that can successfully pass compilation, reflecting the foundational quality of cross-lingual translation in terms of syntactic validity. It is typically reported as a percentage or a score between 0 and 1. This metric is widely used in related benchmarks and papers and can effectively reflect model performance on this dimension. Higher values are better. It helps researchers and engineers quantify the actual performance differences of models in code translation / cross-lingual transfer scenarios, facilitating horizontal comparisons across different methods or model versions.
