Dataset is imported from CodeXGLUE and pre-processed using their script.

Task Definition

Code refinement aims to automatically fix bugs in the code, which can contribute to reducing the cost of bug-fixes for developers. In CodeXGLUE, given a piece of Java code with bugs, the task is to remove the bugs to output the refined code. Models are evaluated by BLEU scores, accuracy (exactly match) and CodeBLEU.

Dataset

We use the dataset released by this paper(https://arxiv.org/pdf/1812.08693.pdf). The source side is a Java function with bugs and the target side is the refined one. All the function and variable names are normalized. Their dataset contains two subsets ( i.e.small and medium) based on the function length. This dataset is small.
