Accessing Cultural Heritage collections using Semantic Web techniques
Background
• CATCH • Continuous Access To Cultural Heritage• Funded by NWO• 10 computer science research projects applied to the
Cultural Heritage field• Personalization of access• Image and text analysis for creating metadata• …
• STITCH• SemanTic Interoperability To access Cultural
Heritage• Exchanging and integrating metadata

Accessing Cultural Heritage collections using Semantic Web techniques
Some Needs for Cultural Heritage Collections
• Representation of objects and knowledge about them • Pointing at collection objects• Describing them (creating metadata)
according to specific• Metadata structures (schemes)• Controlled expert vocabularies (e.g. thesauri)
• Accessing object using metadata • E.g. search using information contained in
thesauri

Cultural Heritage Collections and Semantic Web
• Need to categorize/classify things• Need to structure representations
• Using MD schemes is similar to using relations
Semantic Web techniques are good candidate for representing Cultural Heritage metadata

Accessing Cultural Heritage collections using Semantic Web techniques
Publishing Cultural Heritage vocabularies on the Semantic Web
• Situation: a lot of knowledge up there• Aim: providing domain expertise to the outside
world• Thesaurus web services
• Aim: a global network of collection and vocabularies• Coordinating different vocabularies
• Problem: need to enforce some homogenization• Many different models and formats

Cultural Heritage Interoperability Problems
• Current trend: accessing different collections simultaneously
• Problem: integrating different databases/metadata schemes/vocabularies
• Syntactic interoperability can be solved• Common metadata scheme• Common vocabulary model (SKOS?)
• How about conceptual heterogeneity?
![Page 27: Accessing Cultural Heritage Collections using Semantic Web Techniques Antoine ISAAC (inluding cool graphics by Frank van Harmelen) STITCH Project Book.](https://reader035.fdocuments.us/reader035/viewer/2022070307/551a749c550346761a8b4ab4/html5/thumbnails/27.jpg)
Accessing Cultural Heritage collections using Semantic Web techniques
The semantic interoperability problem
• There is no standard thesaurus• We don’t really want it
different vocabularies for different expertise domains, traditions, tasks
• Consequence:• “klassieke ruïnes” vs. “landschap met ruïnes”• “maagd Maria” vs. “Heilige Moeder”
• Practical problem:• Searching for “Heilige Moeder” misses “maagd
Maria”• Unless we know both vocabularies

Accessing Cultural Heritage collections using Semantic Web techniques
Vocabulary alignment
• STITCH aim: find correspondences between vocabulary elements• “klassieke ruïnes” ≈ “landschap met ruïnes”• “maagd Maria” = “Heilige Moeder”
• Doing it automatically• Vocabularies are big (tens of thousands concepts)• They evolve• Application can change their reference vocabularies
• Using techniques from• Linguistics• Computer science• Statistics

Conclusion: Semantic Web can help Cultural Heritage
• Representation of collections and
associated expert vocabularies• Publication and access• Semantic integration
New opportunities for making knowledge accessible
