GraphGeeks Explainer S2 Ep1: Exploring News at Scale with On-the-Fly Graphs

How do you build a knowledge graph that processes millions of new entities and relationships every day—and make it easy to explore through natural conversation? In this talk, Rob Caulk, the founder of Emergent Methods and open source veteran with over 1000 academic citations, will share how their team fine-tuned Phi-3-mini-4k to outperform Claude Sonnet 3.5 in graph extraction for dynamic knowledge wrangling at scale. Rob will take you behind the scenes, breaking down key innovations: creative dataset engineering, novel loss metrics, and subjective evaluation methods that significantly boost accuracy in the AskNews software. You’ll also learn how the team enabled on-the-fly sub-graph creation to enable targeted, domain-specific exploration of news. We’ll wrap up with a live demo, showing how to build and interact with a custom finance sub-graph—giving you practical strategies to apply knowledge graph exploration for your own use cases.
