So-called “Meaning Triangle” CONCEPT Refers To Symbolizes “Rose”, “ClipArt” Stands For Referent • Concept world • Representation world • Real world Source:Emerging Semantic Technology Standards by Bruce Bargmeye , OFMR2009, Seoul
Meaning triangle and ISO 1087-1 CONCEPT Refers To Symbolizes “Rose”, “ClipArt” Stands For Referent • ISO 1087-1 uses the framework of “Meaning triangle” • 3.2 Concept Example: concept, concept system • Concept world • Representation world • Real world Example: designation, nomenclature, definition • 3.4 Designations 3.5 Terminology 3.3 Definition • 3.1 (Language and) reality Example: Object, Subject field
ISO 1087-1 and MDR CONCEPT Refers To Symbolizes “Rose”, “ClipArt” Stands For Referent • 3.2 Concept • Concept world Example: concept, concept system Very confusing Example: Concept, Concept_System Example: designation, nomenclature, definition • 3.4 Designations 3.5 Terminology 3.3 Definition • Real world MDR • Representation world
Meaning triangle and RDF, OWL, Common Logic etc. A model, which is an interpretation that makes all the sentences true, may be interpreted as a concept system since it is a kind of function from Representation world. • 3.2 Concept • Concept world CONCEPT • 3.4 Designations 3.5 Terminology 3.3 Definition Refers To • 3.1 (Language and) reality Symbolizes “Rose”, “ClipArt” Stands For • Real world Referent • Representation world • Most of ontology languages such as RDF, OWL, Common Logic etc. handles Real world and Representation world only.
MDR and RDF, OWL, Common Logic etc. RDF, OWL, Common Logic etc.represent Real world • Concept world MDR represents Concept world RDF, OWL, Common Logic etc. • 3.2 Concept CONCEPT • 3.4 Designations 3.5 Terminology 3.3 Definition Refers To • 3.1 (Language and) reality Symbolizes “Rose”, “ClipArt” Stands For • Real world Referent • Representation world MDR
Inconsistency of term definition in MDR CONCEPT Refers To Symbolizes “Rose”, “ClipArt” Stands For Referent • Concept and relation lie in the different world. (cf. JPN-p01-005) • 3.2 Concept Example: concept, concept systemC • Concept world MDR uses the definitions of ISO 1087-1 for concept and concept system. • Real world relation, universe of discourse • Representation world Relation is defined in terms of universe of discourse in MDR. Universe of discourse lies in Real world both in the sense of TR9007 and ISO/IEC 24707 Common Logic.
