The document outlines the Judaicalink project, co-funded by the European Union, aimed at creating linked data from Jewish encyclopedias. It details the project's structure, data acquisition methods, and potential applications for enhancing authority data, including collaboration with partner organizations. Future plans involve seeking funding and expanding the data linking with scholarly and other encyclopedia content.

5. Dbpedia inspired

6. The YIVO Encyclopedia
JudaicaLink: Linked Data from Jewish Encyclopediae 620.01.2015

7. What data can we find?
• A title
• Describing text
• Links in texts
"Surface form"  Concept
• Pictures
• Description of pictures

8. More data?
• Subconcept relations
Minsk article links to
"Poland before 1795" calling it
"Polish-Lithuanian Commonwealth".
"Polish-Lithuanian Commonwealth"
is a subsection of "Poland before 1795"
in the main article "Poland".
• So is "Demography"… first level
of subsections seem to work better as
subconcepts, but not very reliable.

9. How do we get the data?
• https://github.com/kaiec/judaicalink-crawler
• Node.js based crawling scripts written in CoffeeScript:

10. Access to HTML via jQuery

11. Intermediate JSON representation

12. And finally: RDF and Linked Data

Backlinks
Same As Links
Alternative Labels

13. Encyclopedia on Russian Jewry
• Articles in Russian (about 20.000! Yivo: 2.300)
• No images
• Less links (~ 1.5 per article, Yivo: > 10!)

14. Upcoming: Das Jüdische Hamburg
• Articles in German (261)

15. Interlinking
• So far only preliminary links have been created.
• Very simple, label-based approach.
• Exploiting Dbpedia's multilinguality.

"Minsk" "Минск"
"Минск" @ru
"Minsk" @en

16. What can we do with the data?
• JudaicaLink is an alternative source for authority data:
Persons, Locations, Subjects.
• We are in contact with potential linking partners:
– Europeana,
– the German National Library and
– the National Library of Israel.
• The German National Library started to include data from
third-parties (like JudaicaLink) into the GND.
• Most promising for a successful "match&merge": Persons.

17. What else, what's next?
• We are looking for funding!
• Generate links from scholarly content to JudaicaLink
(Grant proposal submitted together with JSTOR).
• Generate links with other data resources and between
the encyclopediae (ongoing research).
• And of course: find more encyclopediae or similar
content to generate Linked Data from.
