## ezio007/Data-StackExchange-Deduped

This dataset was created from **Stack Exchange Data Dump**, consisting of **questions and their accepted answers** related to version control systems and command-line environments.

### Included Tags
The dataset contains content associated with the following tags:

1. svn  
2. mercurial  
3. perforce  
4. tfs  
5. cvs  
6. bazaar  
7. bitkeeper  
8. git  
9. cmd  
10. bash  

### Data Collection
- Questions and **only their accepted answers** were extracted.
- Data was filtered to include **exactly one entry per Question ID**.
- Filtered Question and Answer Quality (q_score>5 && a_score>10)

### Data Cleaning & Preprocessing
- **Exact deduplication** was performed based on `question_id`.
- All entries containing tags related to **GitHub** or **GitLab** (including variants) were removed to avoid platform-specific bias.
- Only tag-relevant, non-duplicated question–answer pairs were retained.

### Purpose
This dataset is intended for:
- Version control system comparison and analysis  
- Command-line and shell usage understanding  
- Training or evaluating NLP models on technical Q&A data
