Exploiting vocabularies and Linked Data: in practice

  1. 1. Exploiting Vocabularies and Linked Data: in practice Kate Fernie, CARARE Abbaye de Saint-Génis-des-Fontaines, PMR Maeyaert, CC-BY-SA
  2. 2. Background CARARE has been working with heritage organisations and archaeologists across Europe since 2010 offering them support and practical assistance in sharing their datasets with Europeana. http://www.carare.eu Network Advice Services Digital heritage
  3. 3. CARARE receives datasets for aggregation to Europeana mainly exported from databases but some captured using spreadsheets or XML editors. We develop tools to help make it easier for people to share their data and improve the quality.
  4. 4. Projects Two recent projects gave us an opportunity to develop new services which exploit vocabularies and linked data: 1. Share 3D: Metadata capture dashboard 2. Europeana Archaeology: Vocabulary services for mapping and enrichment
  5. 5. How can we make it easy for people to use vocabularies and linked data? Share3D focussed on 3D models, but the challenge is the same for all content. Market Cross, Glendalough, The Discovery Programme, CC-BY-NC-ND https://www.europeana.eu/en/item/2020741/object_HA_213
  6. 6. Fast, secure and easy to create We all want to catalogue our content as easily as possible! Printed vocabularies and wordlists are great but these days when you enter data into a system, the system can help ease the process. Extract from the Thesaurus of Monument Types, Forum on Information Standards in Heritage, 2020 http://www.heritage-standards.org.uk/fish-vocabularies/
  7. 7. Share3D dashboard incorporates: ● Getty’s Art and Architecture Thesaurus for subject and period concepts https://share3d.eu/dashboard/ Demo
  8. 8. Demo Share3D dashboard produces: ● Metadata in Europeana’s EDM format https://share3d.eu/dashboard/
  9. 9. Roman tombstone, Society of Antiquaries of London, INC-EDU Most of the datasets CARARE receives include terms from local wordlists in the national language. How can we exploit Linked Data for these datasets?
  10. 10. Mapping vocabularies to Linked Data Vocabularies can be mapped using a simple spreadsheet. It takes time Can we make the process easier for people to exploit their mappings on their datasets? Native Term Lang Aat concept label Aat uid sídlištní cs settlement (population activity) 300410475 pohřbívání cs burials 300263485 výroba cs production (process) 300054713 těžba cs mining 300054710 kult cs rituals (events) 300065284 komunikace cs transportation 300055244 deponování cs storage 300056390
  11. 11. Extracting keywords from a provided dataset - Europeana Archaeology Vocabulary tool: ● Easy to use mapping editor ● Mappings can be imported and built up over time Demo https://europeanaarchaeology.carare.eu/project-results/
  12. 12. Demo Vocabulary tool produces: ● Mappings which can be downloaded ● And used to enrich the original dataset with Linked Data https://europeanaarchaeology.carare.eu/project-results/
  13. 13. Demo The enriched records include URLs pointing to the Getty Vocabularies LOD which gives access to: ○ Preferred concept labels in multiple languages ○ Alternative labels in multiple languages ○ Broader and narrower concepts
  14. 14. Exploiting Linked Data ● Automatic semantic enrichment ● Europeana de-references AAT URLs to add concept labels in all available languages -> enables multilingual searches
  15. 15. How does it look in Europeana? The concept labels are displayed according to the language you choose for your browser Users can browse by concept -> improves discovery
  16. 16. Conclusion Using vocabularies and Linked Data can ease data entry and improve consistency. Using Linked Data can improve discovery of your content by helping users to find connected items using their own language. The Share3D dashboard and Europeana Archaeology Vocabulary service are both freely available online. If you would like to know more please contact CARARE. Network Advice Services Digital heritage
