  • 1. PATHS: Personalising access to digital cultural heritage spaces Kate Fernie MDR Partners (Consulting) Ltd UK Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 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 Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 3. Motivation Large quantities of digital cultural heritage material have become available online Museum exhibitions offer narratives organised by theme yet digital libraries are often limited to a simple keyword search Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 4. Introducing paths We’re introducing the idea of paths into digital library collections This is not a new idea – some online examples are Walden’s Paths, Trailmeme and Timelines Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 5. Research Objectives •  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. •  Educational informatics: adapting to individual learners in relation to being directed and being allowed the freedom to explore autonomously Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 6. User-centred development methodology 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 Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 7. PATHS system The system consists of web-services, data storage and an end-user interface. Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 8. Enriched metadata The PATHS system is based on content from Europeana that has been processed and enriched. Our aims were to: •  Linguistic processing – enrich text metadata with additional keywords and index terms •  Thematic organisation – find a vocabulary to use to organise the items in the collection automatically •  Intra-collection links – to create a network of links between related items in the collection •  Links to Wikipedia – create links to contextual information in Wikipedia •  Links to websites – use Sentiment Analysis to establish links to closely related external websites Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 9. Demo •  Two cycles of user evaluation of prototype systems have been completed •  Here follows a quick demo of the main features Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 10. Published Paths Paths can be created by experts or any registered user Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 11. Path following Continue on this path Description by path creator Users can simply follow a path in a similar way to reading a narrative or viewing an exhibition. Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 12. Encouraging exploration of the collection Going off the path and exploring the links Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 13. Different user scenarios Classroom activities Curated collections Leisure users Local historians Paths Researchers •  PATHS system incorporates tools to support different activity levels from path following to active exploration and use of the contents Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 14. Searching the collections There is a conventional keyword search Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 15. Tools for browsing: thesaurus Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 16. Browsing the collection as a tag cloud Same taxonomy, different view Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 17. Collection overviews: topic map Same taxonomy different view Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 18. Case 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 art-focussed topic in a popular, accessible way, and to encourage further use and exploration of cultural heritage resources.” eCult Dialogue Day, 19th September 2013, Dubrovnik Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 19. Creating paths Users who have registered and logged into the system can add items to their workspace and create their own paths Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 20. Finding items Users can find items to include in their path by any of the methods above – selecting from paths, search results or by browsing using the thesaurus, tag cloud or topic map Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 21. Workspace You can add items to your workspace until you’re ready to start creating a path or editing one of your existing paths Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 22. Editing paths You can drag and drop items from your workspace to your path, add and edit nodes Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 23. 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 Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 24. User evaluation •  Second round of evaluation trials just completed •  User feedback on the prototype systems has been very good: very positive feedback on path creation tools and search mechanisms •  About to start field trials and evaluation of a mobile app. Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 25. Outcomes •  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. •  Published set of results from the user evaluation trials Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 26. Outcomes •  Potential business benefits include: –  Improving user experiences when searching large collections of data (more than a million items) and to help users discover content which is more relevant –  To implement tools which automatically improve and enrich the quality of the item metadata that is available –  Provision of tools that enable users to collect content, annotations and background material to create a story, trail or exhibition, or to document the sources used in a piece of research Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
  • 27. Route from research to market •  We’re currently in the final stage of our research and development cycle •  The PATHS API is available for testing and system documentation is available •  Market study is currently underway to understand the future market potential. Initial findings suggest: •  Potential demand is for stand-alone components •  and for consultancy services on NLP and evaluation studies •  Suggests that the route to market will be as a suite of tools for implementation in digital library systems Session 8b: 10th October 2013 eChallenges e-2013 Copyright 2013 PATHS
