Linked  Data:  Open  Research  Problems  

Consuming  Linked  Data  Tutorial  World  Wide  Web  Conference  2010

Exactly  1  year  ago  at  WWW2009  

•  BOF  on  a  Research  Agenda  for  Linked  Data  •  hHp://esw.w3.org/SweoIG/TaskForces/CommunityProjects/LinkingOpenData/MadridBOF  

Page 3: Open Research Problems in Linked Data -

2009’s  Top  10  Linked  Data  Research  Issues  

•  Privacy  •  Inter-­‐culturalizaVon  •  CreaVng  Linked  Data  – CreaVng  and  maintaining  links  – Co-­‐reference  – Design  Methodology  

– NLP  for  link  extracVon

2009’s  Top  10  Linked  Data  Research  Issues  

•  UpdaVng  Linked  Data  – SynchronizaVon  Datasets  and  Links  – SPARUL  Federated  TransacVons  – History,  logs,  change  sets,  temporal  tracking  

•  EvaluaVon,  metrics  and  benchmarks  •  Trust  and  Provenance  •  Publish  Linked  Data  – Licensing  – Legal  and  social  implicaVons

What  are  the  hot  topics  of  2010  

In  Our  Opinion  

Page 7: Open Research Problems in Linked Data -

Hot  Topics  •  Interlinking  Algorithms  •  Provenance  and  Trust  •  Dataset  Dynamics  •  UI  •  Distributed  Query  •  EvaluaVon  –  “You  want  a  good  thesis?  IR  is  based  on  precision  and  recall.  The  minute  you  add  semanVcs,  it  is  a  meaningless  feature.    Logic  is  based  on  soundness  and  completeness.  We  don’t  want  soundness  and  completeness.  We  want  a  few  good  answers  quickly.”  –  Jim  Hendler  at  WWW2009  during  the  LOD  gathering

Linked  Data  TriplificaVon  Challenge  

•  Open  Track  – Novel  data  sets  that  are  published  as  part  of  the  Web  of  Data  demonstraVng  potenVal  benefit  of  use  within  applicaVons  

– Novel  generic  mechanisms,  approaches  and  technologies  to  publish  Linked  Data    

– ApplicaVons  showcasing  the  benefits  of  Linked  data  to  end-­‐users

Linked  Data  TriplificaVon  Challenge  

•  Open  Government  Track  – Build  web  applicaVon  that  makes  use  of  open  government  datasets  (i.e.  environmental,  cadastral,  geographic,  traffic,  historical,  public  speeches,  elecVon,  corporate  spending,  etc)  

– At  least  one  source  must  be  part  of  Linked  Open  Data.

It’s  lunch  Vme!    •  You  learned  what  Linked  Data  is  •  You  realized  that  there  is  a  lot  of  data  out  on  the  web  

•  You  got  excited  about  Linked  Data  •  You  learned  about  the  different  ways  of  consuming  linked  data  

•  You  realized  that  there  is  sVll  work  to  be  done  •  You  want  to  create  a  Linked  Data  applicaVon  (and  parVcipate  in  the  TriplificaVon  Challenge)
