Talk given at BioDiversity Next, Leiden, 23 October 2019

1. BioStor Next
(AKA: Text-mining BHL: towards new interfaces to the biodiversity
literature)
@rdmpage

2. Biodiversity literature challenges
•Discovery (is it online?)
•Accessibility (can I read it?)
•Machine-friendly (can I process it?)
•Knowledge-friendly (is it linked?)

3. BHL makes stuff available… but where are the articles?

4. BHL Item 261937 before BioStor...

5. … and after BioStor

6. An article from BHL Item 261937 on BioStor
200K+ articles from BHL, running since 2009 (new version last week), https://biostor.org

7. • Extract figures from PDF
• Upload to Zenodo, each with a DOI
• Searchable at ocellus.punkish.org
• Can we do this for BHL?
Beyond the PDF…
(see plazi.ch)

Born digital is “easy” 

Scanned content not so easy 

10. Map of localities extracted from BioStor article

12. H3: A Hexagonal Hierarchical Geospatial Indexing System
https://github.com/uber/h3

14. Biodiversity knowledge graph

15. Linking BHL
Begonia sumbawaensis
https://www.ipni.org/n/77157221-1
BHL doesn’t know
that this is a new
species…
… but IPNI knows that
Begonia sumbawaensis
is described on this page!

16. Time to join the dots…
• Linking BHL to databases (in both directions)
• Link BHL entities to Wikidata (e.g., authors, journals,
articles) (happening already)
• Represent BHL content as linked data (e.g.,
annotations, cf. International Image Interoperability
Framework, IIIF)

17. Extract more articles
Geographic search
Atomise articles
Embed in knowledge graph
