  1. 1. Digital Enterprise Research Institute www.deri.i e Enrichment of Affiliation Networks in SKOS-based Datasets Julia Anaya <julia.anaya@deri.org>, Milan Stankovic and Alexandre Passant DERI – Galway Hypios – Paris SWAP 2010 Bressanone – 21th Sep. 2010© Copyright 2009 Digital Enterprise Research Institute.

  2. 2. OutlineDigital Enterprise Research Institute www.deri.i e Motivation Our Approach – Tripartite model + SKOS – Graph representations – Broader pattern relations – Extended graph A concrete case – Actors graph Perspectives and Conclusions
  3. 3. MotivationDigital Enterprise Research Institute www.deri.i e Users can benefit from LOD by annotating existing content with semantic-rich data However, two users tagging content with different tags are not connected even if the tags are related
  4. 4. Our approach: tripartite model + SKOSDigital Enterprise Research Institute www.deri.i e The tripartite model of tagging or Actors- Concepts-Instance model represent users (actors) annotating resources (instances) with tags (concepts) (P.Mika, 2005) We extend this model by using SKOS broader/narrower properties, that provide generic relation between concepts and available on the LOD cloud
  5. 5. Our approach: graph representationsDigital Enterprise Research Institute www.deri.i e The tripartite model can be represented as a tripartite graph: G=<V,E>, V=A U C U I This graph can be projected into a bipartite Actor- Concepts graph (AC) AC can be folded into 2 unipartite graphs: Actors graph and Concepts graph
  6. 6. Our approach: broader pattern relationsDigital Enterprise Research Institute www.deri.i e Broader/narrower relations between concepts can also be represented as a unipartite directed graph We identify three broader pattern relations: – Parent-child – Sibling – Co-ancestors
  7. 7. Our approach: extended graphDigital Enterprise Research Institute www.deri.i e
  8. 8. A concrete case: Actors graphDigital Enterprise Research Institute www.deri.i e Actors graph obtained from FPGG social networking site Dataset contains: – 14000 authors – 5000 publications – 6000 MeSH concepts
  9. 9. Perspectives and conclusionsDigital Enterprise Research Institute www.deri.i e Implementing an application – To enhance people and documents identification – To visualize the information in the network – To validate preliminary results with the users Enhance information discovery Identifying emerging relations between users based on semantic relation between topics Helping people to connect together Bringing a Social aspect to Semantic Web technologies.
