Demo: Taking Notes and Adding Relationship between Documents/WebPages as part of a progressive Knowledge Graph enrichment process

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”.


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:

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

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

[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

[3] Courtesy of our OpenLink Structured Data Sniffer (OSDS) Browser Extension I verified my notes by clicking on the OSDS icon in the tool bar of my browser.

Here’s what OSDS revealed

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.
