## 🎯 What This Is

A **dual-pipeline GraphRAG system** with **14 novel techniques** from cutting-edge 2024–2025 research, **12 LLM providers** (including free Ollama local), **OpenClaw agent integration**, and a **production Next.js dashboard** — all built on TigerGraph.

| Pipeline A (Baseline) | Pipeline B (GraphRAG) |
|---|---|
| Query → LLM → Answer | Query → **PolyG Router** → **PPR Scoring** → **Spreading Activation** → **Path Pruning** → **Token Budget** → LLM → Answer |
| Simple, expensive | Smart, graph-enhanced, cost-controlled |

## 🌟 14 Novel Techniques

### Graph Retrieval Innovations (from 6 papers)

| # | Technique | Paper | Key Result | Implementation |
|---|-----------|-------|------------|----------------|
| 1 | **PPR Confidence-Weighted Retrieval** | CatRAG `2602.01965` | Best reasoning completeness on 4 benchmarks | `PPRConfidenceScorer` — Personalized PageRank from seed entities, scores = context confidence |
| 2 | **Spreading Activation Context Scoring** | SA-RAG `2512.15922` | **+39% answer correctness** on MuSiQue | `SpreadingActivation` — propagates activation through graph with decay, ranks by signal strength |
| 3 | **Flow-Pruned Path Serialization** | PathRAG `2502.14902` | **62–65% win rate** vs LightRAG | `PathPruner` — finds reasoning paths, prunes by flow threshold, serializes high-reliability first (exploits lost-in-the-middle bias) |
| 4 | **Graph Token Budget Controller** | TERAG `2509.18667` | **97% token reduction** at 80%+ accuracy | `TokenBudgetController` — caps context by token limit, prioritizes by score × relevance |
| 5 | **PolyG Hybrid Retrieval Router** | RAGRouter-Bench `2602.00296` | Adaptive > any fixed paradigm | `PolyGRouter` — 4-class query taxonomy (entity/relation/multi-hop/summarization) → optimal strategy |
| 6 | **Incremental Graph Updates** | TG-RAG `2510.13590` | O(new) vs O(all) recomputation | `IncrementalGraphUpdater` — merge by embedding similarity, scoped community re-detection |

### Architecture Innovations

| # | Technique | Paper | Description |
|---|-----------|-------|-------------|
| 7 | **Schema-Bounded Entity Extraction** | Youtu-GraphRAG `2508.19855` | 9 entity types + 15 relation types — ~90% extraction cost reduction, +16% accuracy |
| 8 | **Dual-Level Keyword Retrieval** | LightRAG `2410.05779` | High-level (themes) + low-level (entities) keywords for dual-channel retrieval |
| 9 | **Adaptive Query Complexity Router** | Original | LLM scores query complexity 0.0–1.0 → routes simple to baseline, complex to GraphRAG |
| 10 | **Graph Reasoning Path Explanation** | Original | Natural language step-by-step traversal explanation (Entry → Traversal → Evidence → Conclusion) |

### System Innovations

| # | Technique | Description |
|---|-----------|-------------|
| 11 | **12-Provider Universal LLM** | Single interface for OpenAI, Claude, Gemini, Mistral, Ollama, Groq, DeepSeek, etc. |
| 12 | **OpenClaw Agent Skills** | GraphRAG as autonomous agent capabilities (CIK model: SOUL + IDENTITY + MEMORY + Skills) |
| 13 | **Live Dashboard Benchmarking** | "Run Benchmark Now" button — judges can evaluate both pipelines in real-time |
| 14 | **Advanced GSQL Queries** | PPR, shortest paths, spreading activation, neighborhood extraction — all as installable TigerGraph queries |

### How the Novelty Engine Works (Pipeline B)

```
Query: "Were Einstein and Newton of the same nationality?"

Step 1: PolyG Router → "multi_hop" (score=0.7) → use graph_traversal
Step 2: PPR from seeds [Einstein, Newton] → score all reachable entities
Step 3: Spreading Activation → expand to 2-hop neighborhood with decay
Step 4: Combined scoring (0.6×PPR + 0.4×Activation) per chunk
Step 5: Token Budget (2000 tokens) → select top chunks, prune 60%+ redundancy
Step 6: Path Serialization → "Einstein →BORN_IN→ Germany, Newton →BORN_IN→ England"
Step 7: LLM generates answer with ranked, pruned, path-structured context
