+## 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**.
+
+### 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
