How to tell the AI what you found. Learn the specific techniques for translating raw graph triplets into descriptive natural language sentences that maximize the LLM's understanding.

Introduction to Graph Data Science (GDS): Data-Driven RAG

Move beyond simple queries. Learn how Graph Data Science (GDS) provides the mathematical metrics to identify 'Importance' and 'Structure' automatically across your knowledge base.

Neighbor Ranking: Selecting the Best Context

More isn't always better. Learn how to rank the neighbors of a retrieved node to ensure that only the most relevant, high-quality facts make it into your AI's limited context window.

Centrality Algorithms: Finding the Key Players

Discover the mathematical heart of your graph. Learn how to use PageRank, Degree Centrality, and Betweenness to automatically identify the most influential entities in your RAG system.

Building Narrative Context via Path Descriptors: Connecting the Dots

Tell the story of the connection. Learn how to describe multi-hop paths to an LLM so it understands the 'Chain of Evidence' between two distant entities.

Community Detection: Contextual Clustering

Find the hidden tribes in your data. Learn how to use the Leiden and Louvain algorithms to group your Knowledge Graph into semantic communities for automated hierarchical summarization.

Handling Token Limits in Graph Expansion: The Budgeting Act

Don't choke the LLM. Learn how to manage the 'Explosion' of context that happens during graph expansion and how to use 'Soft' and 'Hard' token budgets to keep your costs under control.

Link Prediction: Guessing the Missing Facts

Fill the gaps in your knowledge base. Learn how to use Link Prediction algorithms to identify relationships that SHOULD exist but were never explicitly recorded in your data.

Few-Shot Prompting with Graph Samples: Learning the Grammar

Model the behavior. Learn how to use Few-Shot examples to teach your LLM how to parse graph triplets and follow multi-hop reasoning paths correctly.

Entity Reconciliation: Cleansing the Graph

Solve the 'Duplicate Entity' problem mathematically. Learn how to use Similarity algorithms to identify when multiple nodes actually represent the same real-world object.

Structured Context: YAML vs Markdown vs JSON for Graphs

The syntax of success. Explore the pros and cons of different data formats for presenting Knowledge Graph subgraphs to an LLM and find the one that balances token cost with reasoning accuracy.

Using GDS to Pre-Rank Knowledge for RAG

Prepare your knowledge for the spotlight. Learn how to combine centrality, community, and similarity scores into a single 'Retrieval Score' that guides your AI to the best facts in milliseconds.

Module 12: Reasoning and Multi-Hop Inference

Enable complex multi-step answering using explicit graph-based paths.

Implicit vs Explicit Reasoning in Graph RAG

The two paths to truth. Learn the difference between letting the LLM 'Guess' the connections (Implicit) and providing the exact topological path (Explicit) for reliable answers.

The Metrics of Graph Retrieval: Measuring Success

Master the KPIs of Graph RAG. Learn how to calculate Recall, Precision, and Faithfulness, and why these metrics differ when you are measuring connections vs. simple semantic similarity.

Teaching models to 'Walk' the Path: Chain-of-Topology

Master the art of 'Chain-of-Topology' prompting. Learn how to instruct an LLM to navigate a series of relationships step-by-step to arrive at a multi-hop logical conclusion.

G-Eval for Graph-Grounded Evaluation: The Judge Agent

Let the AI grade itself. Learn how to use G-Eval to build a 'Judge LLM' that evaluates the reasoning chains and relationship accuracy of your Graph RAG system.

Recursive Retrieval: The Thinking Agent

Iterate to clarity. Learn how to build 'Recursive' retrieval loops where the AI agent queries the graph, evaluates the results, and performs follow-up queries until the information gap is closed.

Building a Test Suite: The Graph Benchmark

Challenge your AI with the impossible. Learn how to create a diverse suite of test questions that stress-test your graph's depth, breadth, and multi-hop reasoning capabilities.

Constraint Injection in Multi-Step Inference

Stay in the lines. Learn how to inject hard business constraints—like time, budget, or department—into your AI's reasoning chain to ensure its conclusions are practical and permitted.

Measuring Hallucination: The Multi-Hop Reality Check

Detect the invisible lies. Learn how multi-hop reasoning increases the risk of 'Imaginary Links' and how to build automated checks to verify every step of the AI's logical chain.

Detecting Path Contradictions in Reasoners: The Truth Auditor

Solve the 'Conflicting Fact' problem. Learn how to instruct an LLM to identify when two different paths in the graph lead to contradictory conclusions and how to resolve the conflict using 'Mathematical Authority' scores.

End-to-End Performance Benchmarking: Latency vs. Wisdom

Measure the speed of thought. Learn how to profile the entire Graph RAG pipeline—from embedding generation to complex graph traversal—to identify the bottlenecks in your AI infrastructure.

The 'Graph-Grounded' Answer: Verifying the Logic

The final proof. Learn how to implement a 'Verification Step' that programmatically checks if every claim in the AI's final answer can be traced back to an explicit edge in your Knowledge Graph.

Continuous Improvement: The Feedback Loop

Build a self-improving system. Learn how to use user feedback (thumbs up/down) to automatically identified 'Weak Spots' in your graph and refine your ingestion and retrieval strategies over time.

Module 14: Performance, Scale, and Cost Optimization
