Traditional experience
Usually, inside an art gallery we can find few information elementsas:
I Information cards with minor information.
I Audioguides with extended information.

Tourism experience at art galleries 4 / 33
Limitations
I The area of the information cards is limited.I The hardware of audioguides is limited to audio and few text
characters.I Deaf people can not use them.

How can we enrich theinformation received inside an art
gallery?
Our proposal
Including the capabilities of the smartphones in the environmentof the museums.

Smartphones into art galleries
There are some art galleries that have their own mobileapplications:
I Orsay’s Museum (Paris).I MoMA (New York).I Museo de reproducciones (Bilbao).

MoMu
MoMu (Mobile Museum) offers additional information about thepieces of art, using TRIP codes [Lopez-de-Ipina02].
MoMu does not offer any innovation in the informationrecovery process.

Our solution
I Usage of QR Codes to identify the pieces of art.I Linked Data to manage the recovery of information.

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.

Architecture Overview
1) Information insertion
4) <HTML>
5) Data curation
System Architecture 15 / 33
Information Enrichment Scenario
A 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 ofart.
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
Information Consuming Scenario
Enables 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
Some notes
The workflow of our system requires many HTTP requests anddata transmission...The DBPedia can return ambiguous results...

Conclusions
I The synergy between QR Codes and Linked Data increasesthe tourism experience in art galleries.
I QR Codes can identify everyday objects and Linked Data canenrich the information about these objects.
I The proposed solution is easily deployable and no specialhardware is needed.
I User interface can be adapted to the needs of different users.I Our system can be migrated to many tourism
infrastructures.
Conclusions and Future Work 29 / 33
Future Work
I We have tested the system at Sala Kubo (Kursaal,Donostia/San Sebastian).
I CICTourgune is analysing the system in terms of usage andusability.
I Improve the percentage of authors found adding moresemantic resources like Amsterdam Museum semanticrepository or GoogleArt wrapper.
I Increase the user experience improving the visualization ofthe data into the smartphone.
