## What the Demo Shows

### The Virtuous Cycle

```
Step 1: Initial Coverage      → 50% SKOS coverage
Step 2: Initial Mapping        → 45% success rate, 8 unmapped columns
Step 3: First Enrichment       → Add SKOS labels for high-confidence suggestions
Step 4: Re-validate Coverage   → 70% SKOS coverage
Step 5: Re-map with Enrichment → 75% success rate, 3 unmapped columns
Step 6: Second Enrichment      → Add more SKOS labels
Step 7: Final Mapping          → 90% success rate, 1 unmapped column
Step 8: Analyze Statistics     → View quantified improvement
```

### Quantified Results

| Metric | Initial | After 1st | After 2nd | Total Δ |
|--------|---------|-----------|-----------|---------|
| SKOS Coverage | 50% | 70% | 85% | **+35%** |
| Mapping Success | 45% | 75% | 90% | **+45%** |
| Avg Confidence | 0.52 | 0.72 | 0.88 | **+0.36** |
| Unmapped Cols | 8 | 3 | 1 | **-7** |
| High Conf Matches | 2 | 8 | 12 | **+10** |

## How to Run the Demo

### Quick Start (5 minutes)

```bash
cd /path/to/SemanticModelDataMapper
python3 examples/demo/run_demo.py
```

The script will pause between steps for observation.

### Manual Exploration

```bash
cd examples/demo

# 1. Check initial coverage
rdfmap validate-ontology \
  --ontology ontology/hr_ontology_initial.ttl \
  --verbose

# 2. Try initial mapping
rdfmap generate \
  --ontology ontology/hr_ontology_initial.ttl \
  --data data/employees.csv \
  --target-class http://example.org/hr#Employee \
  --alignment-report alignment_reports/report_1.json

# 3. Enrich ontology
rdfmap enrich \
  --ontology ontology/hr_ontology_initial.ttl \
  --alignment-report alignment_reports/report_1.json \
  --output ontology/hr_ontology_enriched_1.ttl \
  --auto-apply --min-confidence 0.7

# 4. Re-map with enriched ontology
rdfmap generate \
  --ontology ontology/hr_ontology_enriched_1.ttl \
  --data data/employees.csv \
  --target-class http://example.org/hr#Employee \
  --alignment-report alignment_reports/report_2.json

# 5. View improvement statistics
rdfmap stats \
  --reports-dir alignment_reports/ \
  --verbose
```
