The COVID-19 Problem
License CC-BY-SA 4.0 (International).3
The COVID-19 Problem: Data, Information, Knowledge
Global Understanding of this Virus is suboptimal due to shortcomings
related to:
• Measurements (Data)
• Subject Test Count?
• Metrics (Information)
• Infection, Fatality, Recovery Rates
• Insights (Knowledge)
• Curves across Continents, Countries, Provinces, Municipalities
Compounded by Disparate Data, Dashboards, and Data Visualizations!
License CC-BY-SA 4.0 (International)4
The COVID-19 Solution: Loosely-Coupled Data,
Information, Knowledge
Creating Harmonized Data, Information, and Knowledge without the
impedance of Data Wrangling, courtesy of existing Open Standards.
The cost of ignoring Open Standards has always been high, but now it is
a real problem experienced by everyone, courtesy of the COVID-19
pandemic!
License CC-BY-SA 4.0 (International)5
The FORCE Behind The Solution
License CC-BY-SA 4.0 (International).6
The FORCE: Linked Data, Information, Knowledge
Global generation of Data, Information, and
Knowledge Networks at rates that match and
exceed the COVID-19 infection rate, courtesy
of Open Standards.
Existing Network Examples Include:
• Computer Networks (Internet)
• Document Networks (Web)
• Data Networks (Linked Data)
• Knowledge Networks (LOD Cloud
Knowledge Graph)

The LOD Cloud Knowledge Graph
Initialized in 2007, courtesy of two
major bootstrap nodes:
• DBpedia – General Knowledge
from Wikipedia
• Bio2RDF – Healthcare and Life
Sciences Data, Information, and
Knowledge across a spectrum of
databases and knowledge bases.
License CC-BY-SA 4.0 (International)16
Life Sciences Sub-Cloud –
Segment of the LOD Cloud seeded by Bio2RDF
License CC-BY-SA 4.0 (International)17
Harnessing The FORCE
License CC-BY-SA 4.0 (International).18
Progressively Update the LOD Cloud
Knowledge Graph by leveraging
Hyperlinks as powerful “Super Keys”
for harmonized access to Disparate Data
Sources.
Thereby bringing the magic of the World
Wide Web to the fight against COVID-19.
Hyperlinks as Entity, Entity Type,
Entity Relationship Type Identifiers
License CC-BY-SA 4.0 (International)19
Use of Bookmarking interaction
pattern to create and update
Knowledge Graphs —
• Visit a Document of interest
• Click on the a complimentary
Browser Extensions
(or just use a known URL-pattern)
And the following happens
• Entity Extraction
• Entity Identification
• Entity Description
No Data Wrangling Friction!
Use-case – Progressive Knowledge Graph Population
License CC-BY-SA 4.0 (International)20
Generates Linked Open Data from a
wide variety of Data Sources:
• URL-Patterns
• Browser Extensions that generate
required URL-Pattern
• Public SPARQL Query Service
integration exposed via an Endpoint
That includes:
• CSV Documents
• JSON Documents
• KML Documents
• RDF-Turtle, RDF-XML, JSON-LD etc
• Others

• My COVID-19 Notes
• Data Wrangling and Progressive LOD Cloud Knowledge Graph Enhancement
• What is the Linked Open Data Cloud, and why is it important?
• Simple Linked Data Deployment Tutorial
• What is Small Data, and why is it Important?
• What is the Virtuoso Sponger Middleware about, and why is it important?
