1 like1,532 views
The document outlines key research issues in linked data from a 2010 tutorial at the WWW Conference, emphasizing topics like privacy, interlinking algorithms, and user interface design. It highlights ongoing challenges such as maintaining links, evaluation metrics, and publishing linked data, alongside the introduction of the linked data triplification challenge for promoting practical applications. Participants are encouraged to engage with linked data and innovate solutions by competing in the challenge, increasing awareness and usability of this data.
Open Research Problems in Linked Data - WWW2010
- 1. Linked Data: Open Research Problems Consuming Linked Data Tutorial World Wide Web Conference 2010
- 2. Exactly 1 year ago at WWW2009 • BOF on a Research Agenda for Linked Data • hHp://esw.w3.org/SweoIG/TaskForces/ CommunityProjects/LinkingOpenData/ MadridBOF
- 3. 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
- 4. 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
- 5. 2009’s Top 10 Linked Data Research Issues • UI – User Interface/InteracVon and Usability – Visualizing Linked Data – Natural Language Interfaces • Internet of Things (sensors) • Social and Economic Impact • Web Scale Data Management – Indexing – crawling
- 6. What are the hot topics of 2010 In Our Opinion
- 7. 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
- 8. 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
- 9. 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
- 10. 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)
