Exactly 1 year ago at WWW2009 •  BOF on a Research Agenda for Linked Data •  hHp://esw.w3.org/SweoIG/TaskForces/ CommunityProjects/LinkingOpenData/ MadridBOF

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

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 Thanks Michael Hausenblas

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. Submission due MAY 18 hHp://www.triplify.org/Challenge/2010

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)
