## 🛠️ How to Use the Trained Model

### Basic Usage
```javascript
const EnhancedATSSkillMatcher = require('./enhanced_ats_matcher');

const matcher = new EnhancedATSSkillMatcher({
  domainAware: true,
  adaptiveThresholding: true
});

await matcher.initialize();

const result = await matcher.analyzeMatch(resumeText, jobDescription);
console.log('ATS Score:', result.ats_score);
console.log('Domain:', result.domain_classification.domain);
```
