Levels of knowledge representation
- The degree of formalization of concepts and their relations varies
considerably between various domains of knowledge
- Lower end
- lexicons and simple taxonomies (ordered classification system where
terms are related hierarchically)
- example: Iconclass
- Middle level
- thesauri (controlled vocabularies that are structured
to show relationships between terms and concepts, and, for example, allow for
retrieving them from a database)
- example: Art & Architecture Thesaurus
(AAT)
- High end
- axiomatised logic theories, which include rules to ensure
the well-formedness and logical validity of statements expressed in the language
of the scientific discipline
- example: CIDOC object-oriented Conceptual Reference Model (CIDOC CRM)
