### 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/Defect-detection in Semeru



# CodeXGLUE -- Defect Detection

## Task Definition

Given a source code, the task is to identify whether it is an insecure code that may attack software systems, such as resource leaks, use-after-free vulnerabilities and DoS attack.  We treat the task as binary classification (0/1), where 1 stands for insecure code and 0 for secure code.

### Dataset

The dataset we use comes from the paper [*Devign*: Effective Vulnerability Identification by Learning Comprehensive Program Semantics via Graph Neural Networks](http://papers.nips.cc/paper/9209-devign-effective-vulnerability-identification-by-learning-comprehensive-program-semantics-via-graph-neural-networks.pdf). We combine all projects and split 80%/10%/10% for training/dev/test.


### Data Format

Three pre-processed .jsonl files, i.e. train.jsonl, valid.jsonl, test.jsonl are present

For each file, each line in the uncompressed file represents one function.  One row is illustrated below.

   - **func:** the source code
   - **target:** 0 or 1 (vulnerability or not)
   - **idx:** the index of example

### Data Statistics

Data statistics of the dataset are shown in the below table:

|       | #Examples |
| ----- | :-------: |
| Train |  21,854   |
| Dev   |   2,732   |
| Test  |   2,732   |
