## Model Details

- Model Name: IssueReportClassifier-NLBSE22
- Base Model: RoBERTa
- Dataset: NLBSE22
- Model Type: Fine-tuned
- Model Version: 1.0
- Model Date: 2023-03-21

## Model Description

IssueReportClassifier-NLBSE22 is a RoBERTa model which is fine-tuned on the NLBSE22 dataset.
The model is trained to classify issue reports from GitHub into three categories: bug, enhancement, and question.
The model is trained on a dataset of labeled issue reports and is designed to predict the category of a new issue report based on its text content (title and body).

## Dataset


| Category   | Training Set | Test Set |
|------------|--------------|-------------|
| bug        | 361,239 (50%) | 40,152 (49.9%) |
| enhancement | 299,287 (41.4%) | 33,290 (41.3%) |
| question   | 62,373 (8.6%) | 7,076 (8.8%) |


## Data preprocessing
The data used for training was preprocessed with [ekphrasis](https://github.com/cbaziotis/ekphrasis), adding some regular expressions to remove code, images and URLs. 
Check out our [GitHub](https://github.com/collab-uniba/Issue-Report-Classification-Using-RoBERTa) code for more information about this.


## Metrics

The model is evaluated using the following metrics:

- Accuracy
- Precision
- Recall
- F1 Score (micro and macro average)
