This repository provides the datasets and code for reproducing our paper - The Impact of Mislabeled Changes by SZZ on Just-in-Time Defect Prediction.
Our data is labeled using Daniel's implementaiton of B-SZZ, AG-SZZ, MA-SZZ and RA-SZZ. See the following repositories:
-
Repository for B-SZZ, AG-SZZ, MA-SZZ: https://github.com/danielcalencar/ma-szz
-
Repository for RA-SZZ: https://github.com/danielcalencar/ra-szz
- Clone the code to a directory. Running our code needs the path of the directory.
- Modify a line in the file
code/calculation/classification_importance.R, the line is as follows:
# Specify the DIRECTORY path storing the code of this repository
DIR_PATH = "?"
- Create the following directories in
data_results/:importance,oneway,results_imbalance,results_balance. - Run the script
code/calculation/classification_importance.R
The results will be stored in data_results/importance/, data_results/oneway/, data_results/results_imbalance/, data_results/results_balance/ after running the script. We store the performance scores (e.g., auc) in each of the 1,000 bootstrap iterations into csv files.
