Vocabularies and the semantic web
![Page 7: Summer of Vocabs: Knowledge Organisation Water Resources Management - Environmental Information Infrastructures Megan Williams| Vacation Scholar 29 January.](https://reader034.fdocuments.in/reader034/viewer/2022042800/5a4d1b647f8b9ab0599aec03/html5/thumbnails/7.jpg)
What is the semantic web?
How does it differ from the world wide web ?
• Adds depth to web frameworks
• Uses machine readable formatting
• W3C standards RDF, SPARQL, SKOS
Benefits and Users
• Turns the web into a global database
• Increases usability of data across scientific fields
• Interoperability

Vocabularies
• A lists of terms, preferably with definitions• Governed by a recognized authority, and adopted by a relevant
community• Accessible

Simplified Knowledge Organization System SKOS: a W3C Standard
Focus on the concept rather than the term
• Web/Linked data principle: Concept is identified by a URI • Concept is annotated with text labels (i.e. the traditional ‘term’)
• Structured using hierarchical relations within a vocabulary• broader, narrower
• Matching relations between vocabularies• broadMatch, closeMatch, exactMatch

Reflections
What I’ve Learned
• Existence of Semantic web• Benefits of well maintained
vocabulary services• New computer skill • Gained insight to the world
of computer science• An appreciation of the
complexity behind large projects
What I’m grateful for
• The opportunity to work with CSIRO before finishing my undergrad
• Insight into the research career
• Chance to contribute quality science
• Time and generosity from everyone I’ve worked with
