 This is the data for **Bug Localization** benchmark as part of LCA. 
 The bug localization problem can be formulated as follows: given an issue with a bug description and a repository snapshot in a state where the bug is reproducible, identify the files within the repository that need to be modified to address the reported bug.
 
-The dataset provides all required components for evaluation of **Bug Localization** approaches in real project-level large-scale data collected from GitHub, including:
+The dataset provides all required components for evaluation of bug localization approaches in real project-level large-scale data collected from GitHub, including:
 * Bug issue description
 * Repositories from which the content on the state of the commit SHA where the bug is reproducible can be extracted
 * List of files that should be changed in order to solve the bug
 * Other additional data and metrics, that can be useful in approach development
 
-The collected dataset was carefully filtered, enhances with useful metrics and, what is more, manually labeled, which assures the data quality and provides a golden subset of good examples for evaluation.
+The collected dataset was carefully filtered, enhances with useful metrics and, what is more, manually labeled, which assures the data quality and provides a golden subset of good examples for evaluation.\
+Moreover, the dataset was splitted into several categories, naming:
+
+| **Category**   |  **Description**  |  **Number of data points**  |
+|:------------------:|:----------------------------------------:|:----------------------------------------:|
+| `py` | Only `.py` files in changes | 4,339 |
+| `java` | Only `.java` files in changes | 2,522  | 
+| 'kt'  | Only `.kt` files in changes | 618  |
+| 'mixed' | At list one `.java`, `.py`, or `.kt` file in changes with any other changed files | 2,322 |
+
+And splits, naming:
+| **Split**   |  **Description**  |
+|:------------------:|:----------------------------------------:|
+| `dev` | All collected data point |
+| `test` | Manually verified data point |
+| `train` | Rest data point from `dev` except `test` |
