Hacker News with Generative AI: Knowledge Graphs

Options for Building GraphRAG: Frameworks, Graph Databases, and Tools (memgraph.com)
Building a GraphRAG (Graph-based Retrieval-Augmented Generation) system requires combining structured data (often stored in a knowledge graph) with LLMs to improve the precision and relevance of responses. But how do you go about building one?

Show HN: Knowledge graph of restaurants and chefs, built using LLMs (theophilecantelob.re)
For French restaurant intel, lefooding.com is the definitive data source. Their anonymous critics conduct systematic reviews of establishments across France (and now Belgium), documenting their findings in a witty - if peculiar - style. Beyond choosing the place for a delicious night out, they can be used to map and understand France’s culinary network.

A Guide to Evaluating LLM-Generated Knowledge Graphs (medium.com)
Creating Knowledge Graphs — structured representations of entities and their relationships — from unstructured data has become increasingly valuable beyond just Graph Retrieval Augmented Generation (GraphRAG). While Large Language Models (LLMs) have simplified this process, the critical step of evaluation is often overlooked or missing entirely. Drawing inspiration from comprehensive works on Applied LLM evaluations by Hamel Husain and Eugene Yan, this article provides a practical guide for evaluating your LLM-driven Knowledge Graph creation process.

The Knowledge Graph: things, not strings (2012) (google)
Search is a lot about discovery—the basic human need to learn and broaden your horizons. But searching still requires a lot of hard work by you, the user. So today I’m really excited to launch the Knowledge Graph, which will help you discover new information quickly and easily.

Wikidata as a Giant Crosswalk File (dbreunig.com)
Wikidata is Wikipedia’s structuralist younger brother. It’s contents are seemingly exhaustive, but rather than readable articles, Wikidata expresses itself with structured data. Pick a subject and check out it’s page; it’s like reading the back of a baseball card for, well, anything.
