Grand tour of concepts for object-orientation from a database point of view

Nelson M. Mattos, Klaus Meyer-Wegener, Bernhard Mitschang
1993 Data & Knowledge Engineering  
Numerous papers have defined one or another of its underlying concepts (sometimes in quite different ways), and some systems have been developed following those heterogeneous definitions.  ...  For this reason, the goal of this paper is not to add yet another definition of object-oriented concepts, but to identify existing relationships among these basic concepts that allow one to cover and classify  ...  Acknowledgment The helpful comments of S. Deßloch, L. Golendziner, E. Rahm, and U. Schreier are gratefully acknowledged.  ...

Evidential force aggregation

2003 Sixth International Conference of Information Fusion, 2003. Proceedings of the  
The result of these processes is a complete force aggregation on all levels handled.  ...  These methods work with different type of elements (intelligence reports, vehicles, military units) on different hierarchical levels using specific conflict assessment methods on each level.  ...  The conflict function then returns zero if one classification is a descendant of the other and otherwise returns one. We used the hierarchy shown in Figure 7 .  ...

Aggregation in Ontologies: Practical Implementations in OWL [chapter]

Csaba Veres
2005 Lecture Notes in Computer Science  
We explore possible techniques for modeling aggregation with OWL, investigate the semantics of aggregation, and consider the merits of aggregation over generalization for modeling knowledge in particular  ...  It is based on the observation that current ontologies emphasize the abstraction mechanism of generalization but ignore the various forms of aggregation.  ...  Acknowledgements This work was partly sponsored by the Norwegian Research Council through the WISEMOD project, number 160126V30 in the IKT-2010 program.  ...

On the Key Role of Composition in Object-Oriented Modelling [chapter]

Friedrich Steimann, Jens Gößner, Thomas Mück
2003 Lecture Notes in Computer Science  
We contrast our view of composition with that of it being a special kind of association, with the composition of deployable elements, and with UML's model management constructs such as packaging. »The  ...  The success of object-oriented software modelling depends to a large extent on the ability to create adequate abstractions.  ...  However, such is really a design pattern and not a native modelling element of the language. A UML subsystem constitutes an independent part of the whole system.  ...
