### 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-POJ-104 in Semeru


# CodeXGLUE -- Clone Detection (POJ-104)


## Task Definition

Given a code and a collection of candidates as the input, the task is to return Top K codes with the same semantic. Models are evaluated by MAP@R score. MAP@R is defined as the mean of average precision scores, each of which is evaluated for retrieving R most similar samples given a query. For a code (query), R is the number of other codes in the same class, i.e. R=499 in this dataset.


## Dataset

We use [POJ-104](https://arxiv.org/pdf/1409.5718.pdf) dataset on this task.


### Data Format


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

   - **code:** the source code
   - **label:** the number of problem that the source code solves
   - **index:** the index of example

### Data Statistics

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

|       | #Problems | #Examples |
| ----- | --------- | :-------: |
| Train | 64        |  32,000   |
| Dev   | 16        |   8,000   |
| Test  | 24        |  12,000   |
