  • 9. Traditional experienceUsually, inside an art gallery we can find few information elementsas: Information cards with minor information. Tourism experience at art galleries 4 / 33
  • 10. Traditional experienceUsually, inside an art gallery we can find few information elementsas: Information cards with minor information. Audioguides with extended information. Tourism experience at art galleries 4 / 33
  • 11. Limitations The area of the information cards is limited. The hardware of audioguides is limited to audio and few text characters. Deaf people can not use them. Tourism experience at art galleries 5 / 33
  • 12. How can we enrich theinformation received inside an art gallery?
  • 13. Our proposalIncluding the capabilities of the smartphones in the environmentof the museums. Tourism experience at art galleries 7 / 33

  • 15. Smartphones into art galleriesThere are some art galleries that have their own mobileapplications: Orsay’s Museum (Paris). MoMA (New York). Museo de reproducciones (Bilbao). Related Work 9 / 33
  • 16. MoMuMoMu (Mobile Museum) offers additional information about the ´ ˜pieces of art, using TRIP codes [Lopez-de-Ipina02].MoMu does not offer any innovation in the informationrecovery process. Related Work 10 / 33
  • 17. Our solution Usage of QR Codes to identify the pieces of art. Linked Data to manage the recovery of information. Related Work 11 / 33

  • 19. What is Linked Data?Linked Data is a set of best practices enunciated by TimBerners-Lee and promoted by W3C to publish data on the Web.There are four principles to publish our data as Linked Data[Berners-Lee06]. 1. Use URIs as names for things. 2. Use HTTP URIs so that people can look up those names. 3. When someone looks up a URI, provide useful information using the standards (RDF*, SPARQL). 4. Include links to other URIs so that they can discover more things. Linked Data 13 / 33

  • 22. Information Enrichment ScenarioA web application to ease the work of the data curator of the artgallery. 1. The data curator inserts the title and the author of the piece of art. 2. This input data is queried against DBPedia. 3. The data curator filters the information given by DBPedia. 4. At last, the data curator can add information manually.These Linked Open Data can be reused by another museums! :-) System Architecture 16 / 33
  • 23. Information Consuming ScenarioEnables the user to access enriched information about a concretepiece of art. 1. The user accesses to the application of the museum. 2. Scans the QR Code of the piece of art. 3. The information is shown at his/her smartphone. System Architecture 19 / 33
  • 24. Some notesThe workflow of our system requires many HTTP requests anddata transmission...The DBPedia can return ambiguous results... System Architecture 21 / 33

  • 31. OutlineTourism experience at art galleriesRelated WorkLinked DataSystem ArchitectureExperimentationConclusions and Future Work
  • 32. Conclusions The synergy between QR Codes and Linked Data increases the tourism experience in art galleries. QR Codes can identify everyday objects and Linked Data can enrich the information about these objects. The proposed solution is easily deployable and no special hardware is needed. User interface can be adapted to the needs of different users. Our system can be migrated to many tourism infrastructures. Conclusions and Future Work 29 / 33
  • 33. Future Work We have tested the system at Sala Kubo (Kursaal, ´ Donostia/San Sebastian). CICTourgune is analysing the system in terms of usage and usability. Improve the percentage of authors found adding more semantic resources like Amsterdam Museum semantic repository or GoogleArt wrapper. Increase the user experience improving the visualization of the data into the smartphone. Conclusions and Future Work 30 / 33
