6. Evolving Semantics: Ontology Evolution & Semantic Drifts

This Part introduces the notions of evolving semantics and semantic drift and discusses how ontology evolution could serve as a means for measuring drifts in semantics.

 

Expected learning outcome
  • Get introduced to the advanced notions of evolving semantics, semantic drift, ontology evolution.
  • Be acquainted with a methodology for quantitatively measuring the evolution of ontologies over time.
Level of advancement Advanced – the underlying concepts are rather advanced.
Elements in this part
  1. Recorded lecture.
  2. Supplementary reading: Paper by Wang et al., introducing the methodology for measuring semantic drift in ontologies.
Chronological order  Though not essential, it could help if Supplementary reading: Paper by Wang et al., introducing the methodology for measuring semantic drift in ontologies was read before viewing Recorded lecture.
Estimated time required for completion of the part  Approximately 3.5 hours
