Exploring Europeana - Opportunities, Challenges, Inspirations and Plans

  1. 1. Exploring Europeana -Opportunities, Challenges, Inspirations and Plans David Haskiya 2012-09-27 #TPDL2012
  2. 2. A little bit about me and this presentation• Once an archaeologist, now Product Developer and Product Owner• I’ll talk about browse options, present and future, in the Europeana portal
  3. 3. A little bit about the Europeana portal• Cross-domain: Libraries, Archives, Museums and Audio-visual archives• Multi-lingual: Metadata in 30 languages and content in more than 30 languages
  4. 4. Let’s explore some browse options
  5. 5. Map based search, browse and explore• Challenge 1: Lack of precise coordinates• Challenge 2: Performance with large result sets
  6. 6. Good examples in the GLAM-sector• Swedish National Heritage Board Archaeological Sites&Monuments Search - Fornsök
  7. 7. Good examples in the GLAM-sector• Old Maps Online
  8. 8. Good examples in the GLAM-sector• Neatline for Omeka
  9. 9. Timeline based search, browse and explore• Challenge 1: Lack of time/periods ontology• Challenge 2: Performance with large result sets
  10. 10. Good examples in the GLAM-sector• Mucha Foundation Interactive Timeline
  11. 11. Subject based search, browse and explore No such feature in our portal (but there is in our Exhbitions and Europeana 1914-1918)• Lack of “full domain and language coverage”-ontology is the blocker
  12. 12. A Europeana attempt with a limited scope• Europeana 1914-1918 – Stories of the First World War
  13. 13. A good example from the GLAM-sector• The Walters Art Museum
  14. 14. Person based search, browse and explore No such feature in our portal• Doable! Using VIAF and/or Dbpedia as authorities
  15. 15. Good examples in the GLAM-sector• The Walters Art Museum
  16. 16. Good examples in the GLAM-sector• BBC’s Your Paintings
  17. 17. Curated sets search, browse and explore No such feature in Europeana• Doable!• Challenge: To scale and to relate to curation sites like Pinterest
  18. 18. A good example in the GLAM-sector• The Walters Art Museum
  19. 19. But could we just support user curation?• Pinterest, Gallica’s page with art by Mucha and pins from Gallica
  20. 20. Similarity search, browse and explore No such feature in Europeana• Doable for images• Challenge: Other media types than audio, quality of results
  21. 21. Good examples in the GLAM-sector ?• Otherwise for images: Google Image Search&Googles, TinEye• And for Audio: Shazam
  22. 22. In the pipeline at Europeana
  23. 23. Features we’re considering for 2013• Spatio-temporal browse in the Exhibitions • Using the Neatline plug-in for Omeka• Person based search and browse in the Portal• Image Similarity Search in the Portal • And perhaps 3D similarity search• User curated sets/Digital Storytelling in the Portal• And with limited subject scope: Subject based browse in the Portal • Supported by improved semantic enrichment and ingestion of contextual resources from partners• The latter two we’re likely to do within a concept we’re working on: Europeana Channels
  24. 24. Auto-completion, suggested interaction• Completion suggestion will begin at the 3rd character • In decending order of frequency (so there’s an error in the mockup above…) • Choosing a suggested auto-completion will immediately execute the search • The user can of course ignore the completions and type in what they want• Completion suggestion will comprise phrases • The letters users have typed in matching a suggestion will be bolded (not shown in the mockup above)• Completion suggestions will show the number of hits if chosen• Completion suggestions will show from which field the • This field name will be shown right-aligned in the suggestions: • Title, Creator, Subject, Time/Period, Place • If a specific field has been chosen in the fielded search dropdown only suggestion from that index will be received and when the search is executed it will be as a fielded query
  25. 25. Person based search, browse and explore Creator Language navigation control, English is default Share&EmbedCreatorportrait Link to full Wikipedia article 12 works inBasic facts, some Europeananavigable Link to allAttribution works in Europeana
  26. 26. Image similarity search, browse and explore Link Link• Challenge 1: Quality of results• Challenge 2: Lack of access to high-res images
  27. 27. 3D similarity search, browse and explore Link• Challenge 1: Quality of results good enough?• Challenge 2: Lack of 3D-objects in Europeana
  28. 28. Concept: Europeana Channels
  29. 29. Europeana as a Portal Platform• If we can’t make the entirety of the Europeana portal browseable…• …we can, together with our partners, make sections of it browseable…• …by extending the Europeana portal to become a platform for thematic channels
  30. 30. Europeana Channels are…• “Sections” of the portal offering a richer user experience based on selected thematic content • Vertical search/Domain specific search• Created in collaboration with Europeana network partners/projects/content providers • Open for User Created Content/Annotations via e.g. Semantic tagging, Geotagging and Digital Storytelling• Based on a generic framework allowing the creation of a (theoretically) unlimited number of channels
  31. 31. Wikipedia says…A vertical search engine, as distinct from a general web searchengine focuses on a specific segment of online content. The verticalcontent area may be based on topicality, media type, or genre ofcontent.Vertical search offers several potential benefits over general searchengines: - Greater precision due to limited scope - Leverage domain knowledge including taxonomies and ontologies- Support specific unique user tasksDomain-specific search solutions focus on one area of knowledge,creating customized search experiences, that because of thedomains limited corpus and clear relationships between concepts,provide extremely relevant results for searchers
  32. 32. Specific branding Specific blurb Featured rich media content Specific social media presences Browse per category entry-points Featured thematic Creator page Specific Pinterest or Europeana pinterestSpecific blog or board feedEuropeana blogcategory
  33. 33. Thematic Creatorpage Shareable and embeddableContextual infofrom Dbpedia/Wikipedia Semi-editorially selected works by this Creator and in this theme
  34. 34. Only hits within the themeTheme specificfacets
  35. 35. Direct access to rich media User created galleries allowedAll content clearedfor re-use User tags (public and semantic) allowed
  36. 36. Rich media directaccess Rich media embed functionality
  37. 37. A richer user experience• Exploration by browsing and filtering based on faceted Type and Subject ontologies• Direct access to full media in the portal• Functions for re-use including full media • User created galleries, collections and other re-use functions• Ability to remix, tag and annotate records and media • Ability to upload personal content for inclusion in Europeana • Integration of the Eu. Awareness Digital Storytelling Platform• Access to contextually relevant Creator pages• Access to contextually relevant external sources• Other features, dependent on rich thematic content, can be added incrementally • And also be specific per thematic entry point
  38. 38. Higher demands on content• Must be segmented by topic or genre • Example used in this concept: The First World War• Must be classified into consistent types and/or subjects• Should include direct media links• Should be licensed for re-use• Should contain rich freetext descriptions• Should be multi-lingual
  39. 39. The portal as collaborative publicationplatform• Europeana partners can use the Europeana portal as their own end-user destination site• Europeana partners can brand and style their channel• Europeana partners can access the usage statistics for their channel• Europeana partners can embed their channel on their own site• Europeana partners can interact with users of their channel through semantic tagging and user created stories
