What is the Semantic Web and linked data?
Web 2.0
What is the web?
Document or information retrieval
Search engines
HTML to understand the syntax of the document
Data is mostly stored as metadata
You search and you retrieve which is fine if you know
exactly what you are looking for
Rigid and the information is held in silos
Web 3.0
“I have a dream for the Web [in which computers] become capable of
analyzing all the data on the Web – the content, links, and transactions
between people and computers. A ‘Semantic Web’, which should make this
possible, has yet to emerge, but when it does, the day-to-day mechanisms
of trade, bureaucracy and our daily lives will be handled by machines
talking to machines. The ‘intelligent agents’ people have touted for ages
will finally materialize.”
— Tim Berners-Lee, 1999
What is the Semantic Web?

Taxonomy Development
For example, the GSE taxonomy contains
Climate change, pollution & environmental impacts
- Water pollution
- Air pollution
After enhancing with Library of Congress classification
Climate change, pollution & environmental impacts
- Water pollution – variants: aquatic pollution, water contamination
Marine pollution – variants: ocean pollution, sea pollution
Oil pollution of water – variants: petroleum pollution of water
Estuarine pollution – variants: estuary pollution
- Air pollution
Improved search - Enhancing auto-suggest
Using taxonomy information for “did you mean”

But why do we need it?
Time poor users, information rich environment
Information overload
Content existing in various sites and silos
Low tolerance, users want to find information quickly and easily
Increased reliance on search engines (but tertiary)
In the context of publishing…
Solid foundation for content storage & delivery
Income - Flexibility to repackage content, create new products, drive new features
User can find relevant information – discoverability
Semantically enrich content – gives meaning to the searches so the search engines deliver relevant results
Improving usage of content
User centric digital strategy
Ability to break down content silos & enrich products
Interoperability
Providing external context to content
