From Semantics of Change to Change of Semantics
On 19 May 2015 PERICLES partners ran a half day workshop devoted to the importance of dependency drifts in digital preservation and covered four interlocking research areas:
- the design of a OWL ontology called LRM (Linked Resource Model) to describe change and dependencies in evolving digital ecosystems on a high level;
- the application of the LRM to the representation of domain-specific knowledge, and the principle of "ontology evolution" for the measurement of semantic drift in collections;
- the visualization of evolving semantics using the methaphor of physical fields (ie. using vector field instead of a vector space to model drifting document content and index term meaning);
- the significance of long-term digital preservation in the space science domain and the B.USOC case study.
The sessions have been recorded and can be viewed here:
