PATHS @ LATECH 2013

  1. 1. Generating Paths through Cultural Heritage Collections Samuel Fernando, Paula Goodale, Paul Clough, Mark Stevenson, Mark Hall, Eneko Agirre LaTeCH 2013, ACL Workshop, Sofia, Bulgaria.
  2. 2. Introduction Museums have guided tours with narratives organised by theme or chronology while digital libraries are often limited to a simple keyword search LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  3. 3. Introducing paths We introduce the idea of paths into digital library collections. These may be created by experts or end-users. LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  4. 4. Overview What do people want from paths /how might they use them? User studies Analyse properties of created paths Problem: users do not add background text Propose automatic methods to address this LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  5. 5. User interpretations of paths Hypertext trails Search history Learning process Process oriented Information seeking journey Paths Transaction process LaTeCH 2013, ACL Workshop, Sofia, Bulgaria Linked metadata Through route Augmented reality Starting point / way in Encouraging exploration and enriching data
  6. 6. User scenarios Classroom activities Curated collections Paths Leisure users LaTeCH 2013, ACL Workshop, Sofia, Bulgaria Local historians Researchers
  7. 7. Creating a path (1) Select items from the collection Colosseum Palatine Hill LaTeCH 2013, ACL Workshop, Sofia, Bulgaria Constantine Arch
  8. 8. Creating a path (2) Arrange items to form a path or narrative Colosseum Palatine Hill LaTeCH 2013, ACL Workshop, Sofia, Bulgaria Constantine Arch
  9. 9. Creating a path (3) Add background text /titles etc. Grand Tour of Rome Lorem ipsum dolor sit amet, consectetur adipiscing elit. Colosseum Lorem ipsum dolor sit amet, consectetur adipiscing elit. Palatine Hill LaTeCH 2013, ACL Workshop, Sofia, Bulgaria Lorem ipsum dolor sit amet, consectetur adipiscing elit. Constantine Arch
  10. 10. 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.” LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  11. 11. Search/explore behaviour LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  12. 12. Properties of paths LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  13. 13. Types of ordering LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  14. 14. Adding contextual information LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  15. 15. Automatically adding context Sequence of items (S) Process Key Wikipedia article (K), the most relevant article for S LaTeCH 2013, ACL Workshop, Sofia, Bulgaria Sentences from K summarising S
  16. 16. Methods 1. Choose the first n sentences from K 2. Find key topics W from S and use this to select sentences from K. a. W comprises titles of Wikipedia articles (from using Wikipedia Miner). b. Score each sentence in K by occurrence of words from W multiplied by confidence values. c. Return n highest scoring sentences LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  17. 17. Method 2 example Path: “Bronze age metallurgy” K = “Bronze Age” comprising items and debris W = Bronze Age (0.9) , Copper (0.9), from Bronze Age Alloy (0.8), Tin(0.6), Bronze (0.6) Output 1: A region could be in the Bronze Age either by smelting its own copper and alloying with tin or by trading for bronze from production areas elsewhere (score 3.8) Output 2: The Bronze Age in Ireland commenced around 2000 BC, when copper was alloyed with tin and used to manufacture Ballybeg type flat axes and associated metalwork (score 2.4) LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  18. 18. Results LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  19. 19. Conclusions • Studies analysing different behaviours when creating paths, and properties of created paths • Experts rate importance of context in path, but users tend not to add this when creating their own paths • Automatic methods for adding context show good results using a very simple approach using a key Wikipedia article LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
  20. 20. Future work • Automatic methods for selecting key Wikipedia article • Filter out information from summary that is already present in path • Thank you for your time – please visit the paths system at http://explorer.pathsproject.eu LaTeCH 2013, ACL Workshop, Sofia, Bulgaria
