As indicated in a previous post:
You don’t need to be a programmer to take advantage of the awesome power of Linked Data.

Here is another end-user centric demonstration, using an SAP tweet titled “What are Knowledge Graphs? An Overview”.

Goal

I wanted to rapidly capture some notes as part of a progressive Knowledge Graph enrichment process via a bridge to OpenLink’s Glossary entry for the Knowledge Graph concept which is identified by the Linked Data Principles compliant Hyperlink: About: Knowledge Graph.

Here are the 3 simple steps that I used to achieve my goal:

[1] Download and Install OpenLink Structured Data Sniffer browser extension

OSDS

[2] Describe the article of interest using RDF-Turtle written to a local file.

In this case, simply add a relation that connects (associates or relates) the article to Knowledge Graph entry in the OpenLink Terminology Glossary.

My Notes – using Nanotation

Naturally, once published, you can integrate your notes into the massive LOD Cloud Knowledge Graph using our URIBurner Service, which is a public Virtuoso instance with the Virtuoso Linked Data Middleware module (a/k/a “Sponger”) enabled.
