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.

Authoring Linked Data using Semantic MediaWiki

  1. 1. Authoring Linked Datawith Semantic MediaWiki Laurent Alquier, Pharma R&D Informatics Center, Johnson & Johnson Pharmaceutical Research & Development, L.L.C
  2. 2. Linked DataLinking  Open  Data  cloud  diagram,  by  Richard  Cyganiak  and  Anja  Jentzsch.  h@p://lod-­‐cloud.net/  
  3. 3. How to produce LinkedData ?•  Support still emerging in existing platforms•  Commercial tools are available•  Many more academic or experimental tools Photo  -­‐  shu@erhacks,  “Books”  August  27,  2008  via  Flickr,  CreaNve  Commons  A@ribuNon.  
  4. 4. Augment existing HTMLpages•  RDFa •  Lightweight  annotaNons    •  Adopted by •  Content  Management   Systems  (e.g.  Drupal  7)   •  Search  engines     •  Google  Rich  Snippets   •  Yahoo  SearchMonkey  Photo  -­‐  Hans  Põldoja,    “Tag  cloud”  November,  12  2009  via  Flickr,  CreaNve  Commons  A@ribuNon.  
  5. 5. Map Databases•  D2RQ •  Non-­‐RDF  databases  mapped  as   virtual  RDF  graph    •  R2RML •  W3C’s  RDB  to  RDF  Mapping   language  •  Triplify •  Database  queries/views   mapped  to  RDF   Photo  –  Nate  Grigg,    “IndicaNng”  March  19,  2009  via  Flickr,  CreaNve  Commons  A@ribuNon.  
  6. 6. Convert Files•  ‘RDFizers’ •  CSV   •  XML   •  iCal   •  EXIF,  …  Photo  –  Ravikiran  Rao,    “DSC00391”  February  17,  2006  via  Flickr,  CreaNve  Commons  A@ribuNon.  
  7. 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. 8. Many data integration optionsMediaWiki extensions •  Page attribution, social media, authenticationSemantic extensions •  Forms, drill-down, data integration, result formats, RDFa, triple store connectors
  9. 9. Standardize annotations with forms
  10. 10. Collaboration, Knowledge Managementtools
  11. 11. Seamless semantic layer
  12. 12. Triple store synchronization
  13. 13. Application to Translational Research•  Collaborative data sourcecatalog •  Origin and nature of content •  How to access it •  How it is licensed •  Relationships to other data sources•  Enables easier queriesfrom a single tool •  Both internal and external data sources

  16. 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 storagePhoto  –  Reed  Sturtevant,    “Linked  Data  candies”  January  15,  2010  via  Flickr,  CreaNve  Commons  A@ribuNon.
