  1. CHIME project Mark van Assem Vrije Universiteit Amsterdam supervisor: Guus Schreiber

  2. Cultural Heritage • CHIME: Cultural Heritage in an Interactive Multimedia Environment • Goal: make cultural heritage (more) accessible • Institutions such as Rijksmuseum have large databases with metadata on their collections

  3. Museum Data • Often database or XML • Art works + background info • No links between data • Own set of metadata items to describe objects, e.g. “title”, “maker” • Own set of vocabularies for metadata values (no ontologies, but thesauri or lists)

  4. Problems • Syntactic interoperability (DB, XML, proprietary text format) • Semantic interoperability • Different names for properties of objects “author” vs. “creator” • Different vocabularies “Rembrandt” vs. “Rembrandt van Rijn”

  5. Solutions • Use Semantic Web technology • Syntactic: convert data to RDF or OWL • Work done: method to convert thesauri to RDF/OWL • Semantic • Use standard metadata schema Dublin Core, VRA • Use standard vocabularies AAT, WordNet, TGN, ULAN • Provide mappings between local and global schemas

  6. Metadata schema • Dublin Core metadata schema: creator • Schema 1: author • Schema 2: maker • s1:author rdfs:subPropertyOf dc:creator • s2:maker rdfs:subPropertyOf dc:creator

  7. Standard Vocabularies • tgn: World, Asia, Thailand • Painting1 s1:createdIn Siam • Painting2 s2:madeIn Thailand • s1:Siam owl:sameAs World, Asia, Thailand • s2:Thailand owl:sameAs …

  8. Current focus • Observation: much mapping research is on how to semi-automatically find them • My focus: how to represent mappings and in which situations they may be useful • Role of ontology learning/text analysis techniques: help in converting museum data, finding semantic links between items
