Dear all, I propose an discussion on new topic: Should Closed World Assumption(CWA) and Open World Assumption(OWA) be integrated? My initial argumentations: CWA vs. OWA could be interprated at serveral levels:(1) as notations: CWA and OWA are supposed to be bound to concepts(CPT);we also call that this argumentation is at notation expression level.At this level, integration means simply composition of notations. (2) as concepts: CWA and OWA are supposed to represent the semantics of the individuals who utilize these two concepts to construct their expressions;we also call that this argumentation is at conceptual level (conceptual modeling);At this level, integration actually rely on the integration of both notations and semantics. (3) as semantics: CWA and OWA are different in the sense of existence or ontologically.They can not be integrated since that the level of existence is supposed to be not transcendable in an ultimate sense.We call that this level is at semantic level.At this level, integration actin will mean defying the sense of ultimate of existence/ontology which is the inner character of semantic.Whatever can be done at this level is to identify the order (ORD) and classification (CLA) for the reference of conceptual modeling and validation of compositions of notations of concepts.
