Share: discovery: a focus on papers

  1. 1. SHARE Discovery:Focus on papers @LorcanD Lorcan Dempsey, OCLC 11 October 2013 ARL Fall Forum: Mobilizing the research enterprise #ARLforum13
  2. 2. Aggregation is a pain
  3. 3. Shenghui Wang (OCLC), Antoine Isaac (Europeana), Valentine Charles (Europeana), Rob Koopman (OCLC), Anthi Agoropoulou (Europeana), and Titia van der Werf (OCLC) Hunting for Semantic Clusters: Hierarchical Structuring of Cultural Heritage Objects within Large Aggregations 17th International conference on Theory and Practice of Digital Libraries (TPDL), 22-26 September 2013, Valletta (Malta)
  4. 4. Duplicates
  5. 5. Duplicates? Same object: different providers
  6. 6. Duplicates? Same page: different digital copies
  7. 7. Cataloging error Harvested – points to repository splash page Analytic – essay in book Loaded from Elsevier Loaded from Crossref Three „expressions‟. Cataloging now fixed  Catalan translation
  8. 8. Cross repository record matching issues – confused identities • Different data models – Mapping is lossy. – Relationship issues, e.g. • • • • • Preprint Published article Publisher splash page Repository splash page … • Replication of content across repositories • Different content and „fullness‟ standards • Granularity issues – What is being described? • „Business‟ issues – Publisher wants separate display?
  9. 9. From strings to things … an emerging pattern? Search engines Linked data
  10. 10. The social graph
  11. 11. Three benefits acc to Google: 1. Find the right thing 2. Get the best summary 3. Go deeper and broader Within a discovery service … 1. Aspire to a singular identity for entities/things (people, works, places, organizations, …) 2. Gather data associated with those identities (e.g. „cards‟) 3. Create relationships between identities.
  12. 12. Make data work harder so that the user doesn‟t • Create singular identity („entification‟) • Gather information about entities (e.g. cards) • Create relationships between entities (navigation – citation, co-creation, derivative, affiliation, recommendations, …) • • • Plural - Work with what you have. Wikipedia – an addressible knowledgebase Wikidata/Freebase – source of structured data • Strongly leverage four types of metadata about things .. – „Professional‟ – Crowdsourced (claiming profiles, …) – Programmatically promoted (entity extraction, categorization, clusters, ….) – Usage (relationships based on usage) • Now: shredding records • Future: manage entities in linked data world
  13. 13. National Libraries German Wikipedia VIAF Matching Algorithm Submit VIAF IDs / Show centralized data Wikidata Wikibase VIAF matches Articles / Wikipedia shows matched IDs Read data 3rd Party Users A small example of links/entities Submit VIAF IDs / Show centralized data English Wikipedi Other Wikipedias
  14. 14. The scholarly graph? • Architecture components – Author IDs – Paper/work IDs – Institutions? • Signals of interest – Research analytics – Research workflow • Questions – What is the role of libraries/SHARE/….? – Vivo? – Who will manage entity backbones in linked data world?
  15. 15. Questions and issues …
  16. 16. Repository scope Campus bibliography *-prints Digital materials Tactical ‘structure up’/SEO More links to entities in records - Identifiers Orcid, ISNI, VIAF, … DOI, Pubmed ID, … Schema.org markup Site maps; ResourceSync What do hubs want to see? (e.g. Scholar)
  17. 17. Purposeful syndication Share data with network/disciplinary hubs A discovery service? A discovery destination? The bar is getting higher … A source of data for others?
  18. 18. Sourcing and scaling … Workflow, Repository, Disclosure, Discovery, … Scaling Rightscaling Different things done at different scales Institution, Consortium, ARL, world? Sourcing Collaboratively sourced? Third party? Existing agency? Multiple approaches?
  19. 19. Discovery and SHARE What is Share’s role in creating and/or maintaining the scholarly graph?
