4. Who am I? 4 th year RMIT student Environmental Science/Social Science Citizen Science Future directions / Career in Environmental Science 4 | Summer of Vocabs| Megan Williams

5. Place within CSIRO Working with Simon Cox and the Environmental informatics team at Highett. Finding and Formalizing content for the Semantic web 5 | Summer of Vocabs| Megan Williams

6. Vocabularies and the semantic web

7. 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 7 | Summer of Vocabs| Megan Williams

8. Vocabularies A lists of terms, preferably with definitions Governed by a recognized authority, and adopted by a relevant community Accessible 8 | Summer of Vocabs| Megan Williams

10. 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 Summer of Vocabs| Megan Williams 10 |

20. Reflections

21. 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 Summer of Vocabs | Megan Williams 21 |
