💡 Key Innovations
1. Language Bridge
Problem: Companies say "tech firm"
Candidates say "Python"
→ No match! ❌
Solution: Use job postings as translator
Postings say "Python needed"
→ Perfect match! ✅
2. Cosine Similarity
Why not Euclidean distance?
- Scale-dependent ❌
- Magnitude-sensitive ❌
Why cosine similarity?
- Scale-invariant ✅
- Direction-focused ✅
- Standard in NLP ✅
3. Modular Design
Mock data → Real data = Change 1 line
Easy to:
- Test
- Deploy
- Maintain
- Extend

🎤 Demo Script
Opening (30 seconds)
"This is HRHUB, our bilateral HR matching system.
It uses NLP to match candidates with companies
based on semantic similarity, not keyword matching."
Feature Tour (2 minutes)
1. "Here's a candidate profile" [show left panel]
2. "Top 10 company matches" [show scores]
3. "Interactive network" [drag nodes]
4. "We can adjust parameters" [use sliders]
Technical Deep-Dive (1 minute)
"Under the hood:
- 384-dimensional embeddings
- Cosine similarity matching
- Real-time visualization
- Scalable to 180K companies"
Future Vision (30 seconds)
"Next steps:
- Load real embeddings
- Add candidate selection
- Implement weighted matching
- Build company-side view"
