PATHS at the EAA conference 2013

  1. 1. Tools  for  exploring  Digital  Cultural   Heritage  Spaces   Kate Fernie, Jillian Griffiths,, Mark Stevenson, Paul Clough, Eneko Agirre, Aitor Soroa, Stein Runar Bergheim, Mark Hall and Konstantinos Chandrinos EAA 2013, New Digital Developments in Heritage Management and Research
  2. 2. PATHS: project basics •  A STREP funded under the FP7 programme •  36 month project - 1/1/2011 to 31/12/2013 •  6 partners in 5 countries •  University of Sheffield •  Universidad del Pais Vasco •  i-sieve technologies Ltd •  Asplan Viak Internet Ltd •  MDR Partners •  (Alinari 24 Ora Spa) http://www.paths-project.eu
  3. 3. Introduction Large quantities of digital cultural heritage material have become available online yet digital libraries are often limited to a simple keyword search EAA 2013, New Digital Developments in Heritage Management and Research
  4. 4. Introducing paths We’re introducing the idea of paths into digital library collections They can be created by experts or general users. This is not a new idea – some examples are Walden’s Paths, Trailmeme, Timelines, museum exhibitions EAA 2013, New Digital Developments in Heritage Management and Research
  5. 5. We think we can do more Research areas: •  Information access: Methods for exploring and navigating digital cultural heritage collections, including paths, topic maps, tag-clouds, hierarchical concept structures and recommender services. •  Natural Language Processing: analysing item metadata to improve indexing, enable use of ontologies, and generating links between items in the collection and with external background material (e.g. Wikipedia articles). EAA 2013, New Digital Developments in Heritage Management and Research
  6. 6. User-centred development What do people want from digital libraries / how might they use paths? Users Gather user requirements and behaviours Develop prototype system Evaluate and test system with potential end users http://www.paths-project.eu/eng/Resources/User-Requirements-Analysis
  7. 7. Technology •  PATHS has a flexible modular architecture consisting of web-services, data storage and end-user interfaces •  Natural language processing of the metadata allows search capabilities to be enhanced •  A hybrid model combines RDF/SPARQL with RDB/SQL to deliver performance and robustness •  Web services support users, path creation and editing, querying, interacting with topic hierarchies and a SolrProxy service. EAA 2013, New Digital Developments in Heritage Management and Research
  8. 8. End user interface •  Based on the Web Services and data stores •  The content is from Europeana, enriched by the project EAA 2013, New Digital Developments in Heritage Management and Research
  9. 9. Analysing and enriching metadata •  Initial analysis -> Part-of-speech tagging, named entity recognition, identification of dates, events, multiple word phrases •  Thematic organisation -> analysis of subjects and themes to produce a taxonomy with item clusters •  Intra-collection links -> the similarity between pairs of items in the collection is computed •  Links to Wikipedia -> using Wikipedia Miner •  Links to websites -> using Sentiment Analysis EAA 2013, New Digital Developments in Heritage Management and Research
  10. 10. Demo http://explorer.paths-project.eu/
  11. 11. Published Paths Paths can be created by experts or any registered user
  12. 12. Overview Paths can be linear or include branches And they can intersect with other paths
  13. 13. Path following Continue on this path Description by path creator
  14. 14. Starting to explore Going off the path and exploring the links
  15. 15. Search EAA 2013, New Digital Developments in Heritage Management and Research
  16. 16. Browsing using the thesaurus EAA 2013, New Digital Developments in Heritage Management and Research
  17. 17. Visualising the collection as a tag cloud Same taxonomy, different view EAA 2013, New Digital Developments in Heritage Management and Research
  18. 18. Collection as a topic map Same taxonomy different view
  19. 19. Browsing and finding items All 3 exploration methods - thesaurus, tag cloud or topic map – find the same set of items
  20. 20. Creating paths Users who have registered and logged into the system can add items to their workspace and create their own paths
  21. 21. Workspace You can add items to your workspace until you’re ready to start creating a path
  22. 22. Editing Paths You can edit one of your existing paths by going to your profile page
  23. 23. Editing paths This is an unpublished path that I’m still working on
  24. 24. Drag and drop from workspace I’ve created a new branch by dragging and dropping an item from the workspace
  25. 25. Editing nodes Users can add their own descriptions of the item nodes on a path which can include links to external resources, notes or exercises
  26. 26. Adding text nodes Users can also add text only nodes to a path
  27. 27. Editing the path metadata Each path has metadata which can include keywords, duration, a cover image, description Paths are hidden until you decide to publish
  28. 28. Preview EAA 2013, New Digital Developments in Heritage Management and Research
  29. 29. User scenarios Classroom activities Curated collections Leisure users Paths Local historians Researchers EAA 2013, New Digital Developments in Heritage Management and Research
  30. 30. User study “Imagine you are a student who has been asked to create a path as part of a university assignment. You have been asked to use primary source materials to create a mini online exhibition suitable for a target group within the general public and/or school visitor categories. Your goal is to introduce a historical or artfocussed topic in a popular, accessible way, and to encourage further use and exploration of cultural heritage resources.” EAA 2013, New Digital Developments in Heritage Management and Research
  31. 31. Exploitation •  We’re currently in the final stage of our second development cycle •  The PATHS API is available for testing •  Intended to be suitable for implementation in any digital library system •  Market study and exploitation plan this autumn – some initial findings •  Potential demand for stand-alone components •  Also for consultancy services EAA 2013, New Digital Developments in Heritage Management and Research
