  • 1. Motivation Data on the Web Some eyecatching opener illustrating growth and or diversity of web data LinkedUp – Linking Web Data (for Education) Project Stefan Dietze (L3S Research Center, DE, @stefandietze, http://purl.org/dietze) Stefan Dietze 21/03/14
  • 2. Linked Data for “Open Education”/Learning? Stefan Dietze 1. Linked Data for data sharing, enrichment and interpretation  LD stack (RDF, SPARQL, deref. URIs) to improve interoperability of learning/user data  facilitate vision of Open Education & OER across isolated platforms 2. Linked Data as body of knowledge for learning & education  Vast amount of publicly available resources and (meta)data  Dedicated OER and university data + „knowledge resources“ (from DBpedia to Slideshare) 21/03/14  http://linkededucation.org &  http://linkeduniversities.org
  • 3. „Success models“: data & applications Stefan Dietze 21/03/14 3  LinkedUp Challenge to identify innovative tools & applications  Evaluation methods and approaches “LinkedUp” – Linking Web Data (for Education) L Data curation & profiling Technology transfer & community-building  Collecting & exposing open data of educational relevance => LinkedUp Data Catalog  Profiling and linking of Web Data => LOD dataset profiles  Disseminating knowledge & building communities (educators, computer scientists, data engineers)  Gathering stakeholder feedback: use cases, and requirements European project aimed at advancing take-up of open data and related technologies http://linkedup-challenge.org/#usecases http://linkedup-project.eu/events http://www.linkedup-challenge.org/ http://linkedup-project.eu http://data.linkededucation.org
  • 4. Stefan Dietze 21/03/14 17/09/2013 4 Who we areL LinkedUp Network LinkedUp Consortium LinkedUp Advisory Board
  • 5. Too many/diverse datasets, too little information Stefan Dietze 21/03/14 ? ? ? ?? ?  Which datasets are useful & trustworthy for case XY (eg „learning about the solar system“) ?  Which topics (eg „Astronomy“) are covered?  Accessability/reliability?  Which datasets describe/offer videos (slides, publications, statistics etc)?
  • 6. Data curation and dataset profiling LinkedUp Dataset Catalog Stefan Dietze 21/03/14  Catalog of data (LinkedUp Catalog): classification of datasets according to resource types, disciplines/topics, data quality, accessability, etc  Infrastructure for distributed/federated querying describes  Which datasets are useful & trustworthy for case XY (eg „learning about the solar system“) ?  Which topics (eg „Astronomy“) are covered?  Accessability/reliability?  Which datasets describe/offer videos (slides, publications, statistics etc)?
  • 7. LinkedUp Data Catalog in a nutshell http://datahub.io/group/linked-education http://data.linkededucation.org/linkedup/catalog/  RDF (VoID) dataset catalog: browse & query distributed datasets & mappings  Live information about endpoint accessibility  Federated queries using type mappings Stefan Dietze 21/03/14 http://datahub.io/group/linked-education
  • 8. Dataset profiling: exploring LOD datasets/topics in a nutshell http://data-observatory.org/lod-profiles/ Stefan Dietze 21/03/14  Automatic extraction of dataset “topics” [ESWC2014]  Visualisation & exploration of dataset-topic graph (datasets, topics, relationships)  Includes all (responsive) datasets of LOD Cloud
  • 9. LinkedUp Challenge: using open data for learning  Open Data Competition to promote tools and applications that analyse / integrate (Linked) Web data  Organised by LinkedUp project over 2 years (“Veni”, “Vidi”, “Vici”) with 40.000 EUR awards  Veni Competition - 22 submissions, 8 shortlisted for presentation at Open Knowledge Conference (17 September, Geneva Switzerland) http://linkedup-challenge.org Stefan Dietze 21/03/14 9
  • 10.  Open & focused track(s)  Final events at ESWC2014 (May, Crete)  Open Track only  Final events at OKCon 2013 (September 2013, Geneva)  Open track & focused tracks  Submission details and calls to be released soon  Final events at ISWC2014 (October, Riva del Garda, Italy) May –September 2013 October 2013 – May 2014 May 2014 – October 2014 ?
