The ELAG 2014 workshop focused on linking biographical data using various data sources, highlighting tools like LOD Refine and Silk for creating 'sameas' triples. Participants noted challenges in identifying entities and matching work titles due to a lack of identifiers and inconsistencies in legacy systems. Overall, the event emphasized the need for more open data and robust SPARQL endpoints to facilitate better data linking.
Linking Data with sameAs: Challenges and Solutions - Workshop
- 1. ELAG 2014 Workshop. Bath, UK. 11–12th June 2014 Adrian Stevenson and Jane Stevenson Mimas, University of Manchester, UK @adrianstevenson @janestevenson Linking Data with sameAs: Challenges and Solutions

- 5. Matching • LOD Refine • http://code.zemanta.com/sparkica/download.html • SILK Framework • http://wifo5-03.informatik.uni- mannheim.de/bizer/silk/#workbench 5
- 6. LOD Refine 6
- 7. SILK 7
- 8. Comments on the workshop • ‘great lead-through on LOD refine’ • LOD Refine and Silk seem to be workable tools for creating sameAs triples that can help matching • ‘purpose and possibilities of Silk perhaps a little rushed for me’ • ‘made me realize how disconnected my concept of Silk restrictions and Sparql was. This is now fixed. Ta!’
- 9. Comments on Linking Lives • ‘Great to see the British National Biography (BNB) being used’ • Linking Lives project shows the need for more open data!’ • ‘We need robust Sparql endpoints!’
- 10. Comments… • ‘Funny how hard it is to find useful stuff to link to, and how the user is to make sense of it’. • ‘I feel reconciled!’ • ‘Linking = hard work’
- 11. Challenges Identifying entities: • One of the main problems we came up with in our linked data pilot connecting library catalogue data and theatre performance data was the lack of identifiers for people and works • String matching on personal names and work titles in legacy heterogenous systems is extremely important
- 12. Challenges • Question is how to match work titles in multiple languages.
Editor's Notes
- #2: Mention this is a very gentle and won’t go into much detail given only 4 hours Aim is to get people actually creating some linked data Will inevitably have to gloss over a number of issues. Please leave if think it might be too simple
