# MeetSpot
### AI Agent for Multi-Person Meeting Point Recommendations
*Not just a search tool. An autonomous agent that decides the fairest meeting point for everyone.*

## Why MeetSpot?
Most location tools return results near *you*. MeetSpot calculates the **geographic center** of all participants and returns AI-ranked venues that minimize everyone's travel time.
| Traditional Tools | MeetSpot |
|-------------------|----------|
| Search near your location | Calculate fair center for all |
| Keyword-based ranking | AI-powered multi-factor scoring |
| Static results | Adaptive dual-mode routing |
| No reasoning | Explainable AI with chain-of-thought |
---
## Agent Architecture
MeetSpot is an **AI Agent** - it makes autonomous decisions based on request complexity, not just executes searches.

### Intelligent Mode Selection
The Agent autonomously decides which processing mode to use:
| Factor | Score | Example |
|--------|-------|---------|
| Location count | +10/location | 4 locations = 40 pts |
| Complex keywords | +15 | "quiet business cafe with private rooms" |
| Special requirements | +10 | "parking, wheelchair accessible, WiFi" |
- **Score < 40**: Rule Mode (fast, deterministic, pattern-matched)
- **Score >= 40**: Agent Mode (LLM reasoning, semantic understanding)
### Agent Mode Scoring
```
Final Score = Rule Score × 0.4 + LLM Score × 0.6
```
The LLM analyzes semantic fit between venues and requirements, then blends with rule-based scoring. Results include **Explainable AI** visualization showing the agent's reasoning process.
### 5-Step Pipeline
| Step | Function | Details |
|------|----------|---------|
| **Geocode** | Address → Coordinates | 90+ smart mappings (universities, landmarks) |
| **Center Calc** | Fair point calculation | Spherical geometry for accuracy |
| **POI Search** | Venue discovery | Concurrent async search, auto-fallback |
| **Ranking** | Multi-factor scoring | Base(30) + Popularity(20) + Distance(25) + Scenario(15) + Requirements(10) |
| **HTML Gen** | Interactive map | Amap JS API integration |
