....value refinement. This is due to the fact that the combined use of Isa and Risa relations allows us to derive that the value domain of the inherited property is subclass of several classes. Finally, we would like to emphasize that several rich data models recently proposed, e.g. PSM [16] and ORM [5], do not provide formalizations of property inheritance. 8. CONCLUSIONS In this paper, we have studied a particular form of knowledge inference, namely, property inheritance. Our motivation comes from the fact that when the properties of a class are semantically related, confusion may arise as ....

We call the information (both explicit and derived) that a semantic network carries, the semantics of the network. Several data models use semantic networks to organize information [10, 19, 34, 37, 5, 21, 30, 27, 17, 20, 7] and their usefulness to conceptual modeling is unquestionable. However, many of these models do not provide a formalism defining what the semantics of the semantic network is. This can lead to inconsistencies as (procedurally) derived information cannot be always validated against the ....

Associations and Roles in Object-Oriented Modeling - Chu, Zhang (1997) (6 citations) (Correct)
....are not as well organized and have been criticized as not being object oriented, since they are not tied with any objects. Association class construct makes multiple polymorphism a natural property of association instances, an extension to the current object oriented model. Object role modeling [Bron95, SD96] allows bottom up analysis, based on local relationship properties. Then the roles can be integrated into classes. Object with roles extension to object oriented systems [GSR96, RS91, Pern90, Alba93, WCL97] aims at solving the object evolution problem, thus provides more flexibility to the ....

A Comparison of Role Mechanisms in Object-Oriented.. - Kappel, Retschitzegger.. (1998) (4 citations) (Correct)
....an object with changing behavior is playing one or several roles and that it may learn and forget roles. Note, this notion of a role is in contrast to roles in semantic data models, such as the ER model and the NIAM model, where a role models the part of an entity within a specific relationship [Bron95]. Encountering this obstacle the traditional object oriented model has been extended to cover role related behavior. Some of these extensions are introduced in the next section. 3. Proposed Solutions The notion of role in data modeling is almost as old as data modeling itself and has been ....
