semantic-szz-analyzer
Identify bug-introducing commits using semantic analysis that extends traditional SZZ algorithm. Distinguishes semantic changes from refactorings or code movements using control-flow and data-flow similarity analysis. Use when analyzing bug-fix commits to trace back to bug-introducing changes, investigating software evolution, conducting empirical studies on defect prediction, or reducing false positives in bug localization. Supports git repositories and provides explanations for why commits are identified as bug-introducing.

# Semantic SZZ Analyzer
## Overview
Semantic SZZ Analyzer extends the traditional SZZ (Sliwerski-Zimmermann-Zeller) algorithm by incorporating semantic analysis to identify bug-introducing commits more accurately. It distinguishes actual semantic changes from refactorings or code movements by analyzing control-flow and data-flow similarity across versions.
## Core Capabilities
### 1. Semantic Change Detection
Analyze commits to distinguish between:
- **Semantic changes**: Modifications that alter program behavior
- **Refactorings**: Code restructuring without behavior changes
- **Code movements**: Relocations of code blocks without semantic impact
