| ### Dataset is imported from CodeXGLUE and pre-processed using their script. |
|
|
| # Where to find in Semeru: |
| The dataset can be found at /nfs/semeru/semeru_datasets/code_xglue/code-to-code/Clone-detection-BigCloneBench in Semeru |

| # CodeXGLUE -- Clone Detection (BCB) |
|
|
| ## Task Definition |
|
|
| Given two codes as the input, the task is to do binary classification (0/1), where 1 stands for semantic equivalence and 0 for others. Models are evaluated by F1 score. |
|
|
| ## Updates |
|
|
| 2021-9-13: We have update the evaluater script. Since it's a binary classification, we use binary F1 score instead of "macro" F1 score. |
|
|
| ## Dataset |
|
|
| The dataset we use is [BigCloneBench](https://www.cs.usask.ca/faculty/croy/papers/2014/SvajlenkoICSME2014BigERA.pdf) and filtered following the paper [Detecting Code Clones with Graph Neural Network and Flow-Augmented Abstract Syntax Tree](https://arxiv.org/pdf/2002.08653.pdf). |

|
| ### Data Format |
|
|
| 1. dataset/data.jsonl is stored in jsonlines format. Each line in the uncompressed file represents one function. One row is illustrated below. |
|
|
| - **func:** the function |
|
|
| - **idx:** index of the example |
|
|
| 2. train.txt/valid.txt/test.txt provide examples, stored in the following format: idx1 idx2 label |
|
|
| ### Data Statistics |
|
|
| Data statistics of the dataset are shown in the below table: |
