Semantic Wikis have matured to become much more than wikis. Recent advances in Semantic MediaWiki make it an ideal, low cost platform for data integration and authoring of Linked Data. A practical example applied to Translational Research will be provided. Slides from BioIT World 2011 talk - Informatics track.

3. How to produce Linked
Data ?
• Support still emerging in
existing platforms
• Commercial tools are
available
• Many more academic or
experimental tools

4. Augment existing HTML
pages
• RDFa
• Lightweight
annotaNons
• Adopted by
• Content
Management
Systems
(e.g.
Drupal
7)
• Search
engines
• Google
Rich
Snippets
• Yahoo
SearchMonkey

5. Map Databases
• D2RQ
• Non-­‐RDF
databases
mapped
as
virtual
RDF
graph
• R2RML
• W3C’s
RDB

7. Linked Data using Semantic MediaWiki
• Extension(s) to
MediaWiki
• Used by large BioWikis
• SNPedia,
NeuroLex
• Looks like a wiki - Acts
as Linked Data
• SemanNc
annotaNons
• Tags
with
meaning

8. Many data integration options
MediaWiki extensions
• Page attribution, social
media, authentication
Semantic extensions
• Forms, drill-down, data
integration, result
formats, RDFa, triple
store connectors

9. Standardize annotations with forms

10. Collaboration, Knowledge Management
tools

11. Seamless semantic layer

12. Triple store synchronization

13. Application to Translational Research
• Collaborative data source
catalog
• Origin and nature of
content
• How to access it
• How it is licensed
• Relationships to other
data sources
• Enables easier queries
from a single tool
• Both internal and
external data sources

16. What next ?
• Semantic MediaWiki can
also consume Linked
Data
• MediaWiki
extensions
:
LinkedWiki,
RDFIO,
SMW+
• Standalone
project
:
ShorNpedia
• Upcoming version will use
RDF triples as primary
storage
