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)

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

 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

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
