Data Quality with ICV

Michael Soren

Getting data into the graph is only the first step. Stardog’s Integrity Constraint Validation (ICV) services provide a powerful way to improve data quality in the Knowledge Graph. We’ll learn how this works by looking at some examples from the Knowledge Graph project at NASA that is built on Stardog.

How to Debug Reasoning

Stephen Nowell

This tutorial summarizes the most common questions about reasoning in Stardog. Note that Stardog includes both logical and statistical reasoning capabilities. In this tutorial I’m focusing only on logical reasoning. Background Chances are pretty good you know what reasoning is, what it does, and why it’s important. But just in case, let’s take a very quick refresher on what reasoning is: Reasoning is a declarative way to either derive new nodes and edges in a graph or specify integrity constraints on a (possibly distributed) graph or to do both at the same time.
