Laura Hollink from the Free University of Amsterdam gives an introduction on the semantic Web (SW).
Two reasons for the use of semantic web techniques:
- Machine processable representation of semantic information. Your search engine can reason with the knowledge stored in the the thesaurus.
- Interoperability, link your collection to other collections and let other people/institutions link to your collection and thus enable cross-collection access.
After explaining the building blocks of SW she highlights the SW for libraries and Archives. The standard language for LIS is SKOS. After touching the interoperability challenge, she goes on to highlight some excellent examples of vocabularies available. Union list of artist names, Wordnet, Thesaurus of Geographical Names (TGN).
There follows an example to search collections with different vocabularies making use alignment between thesauri. The examples she is showing come from the e-culture demonstrator. She shows also and exaple in which two pictures are linked to each other based on Semantic Web Rules. How a picture of van Gogh and Gaugin are related to each other. Works in some instances, but not always. Really experimental.
At the end she mentions briefly that these project are in some instances hampered by copyrights as well.
