Exhibition recommendation using British Museum data and Event Registry - ESWC SSchool 14 - Student project

Exhibition recommendation using British Museum data and Event Registry

Introduction • Group 1: Ninja Turtles • Kahina SEMAR-BITAH • Mohamed BEN ELLEFI • Aljaz KOSMERLJ • Peter CLARKE • Tutors • Barry NORTON • José María GARCÍA • •

Problem Definition • Exhibition data (time, date etc.) is stored in natural text in web pages and currently not stored as Linked Data. • Why is this an issue? • What could we do with this information in RDF format?

User workflow

Technology stack

British Museum schema

RETRIEVING BRITISH MUSEUM DATA • Example SPARQL query used to retrieve labels that will map to Dbpedia concept: • In this case, British Museum prefLabels correspond to DBpedia concepts with high accuracy.

Event Registry Integration http://eventregistry.org/json/event?action=getEvents&conceptUri=http://en.wikipedia.org/wiki/Vikings&conce ptUri=http://en.wikipedia.org/wiki/Museum&conceptUri=http://en.wikipedia.org/wiki/Art_exhibition&category Uri=http://www.dmoz.org/Reference/Museums&sortBy=rel&conceptLang=eng&page=0&count=25&resultTy pe=list

Application PROTOTYPE

lESSONS LEARNED • Important to use URIs rather than text for presenting content (DBpedia URI vs “China exhibition”) • In order to be more useful we would need to scrape prefLabels from a number of instances. • Time durations are inaccurate.

ASSUMPTIONS • Assumes a very, very general search over the British Museum data. • Assumes a method of aggregating potentially large number of EventRegistry results of a unreliable quality.

Future Work • Integrate databases from a broader range of museums, i.e. worldwide. • Extend functionality by creating user profiles, e.g. student studying Egyptian Civilization. • More accurate time period ranges. • Utilize tools such as SILK or LIMES for interlinking of museum concepts with DBpedia concepts. • Create more robust and feature-rich interface.
