Automatic Extraction of Ontologies from Teaching Document Metadata

SITS (Scrutable Intelligent Teaching System) is designed to make use of existing learning items in flexible and effective learning interactions.

A major hurdle for reuse is metadata, especially epistemological metadata since different teachers or courses may have different ontologies for a given domain. SITS takes a minimalist approach to metadata. It requires only that the author of a teaching environment should define document metadata specifying the concepts which each document teaches,
