Generalization/specialization and role in object oriented conceptual modeling

Monique Snoeck, Guido Dedene
1996 Data & Knowledge Engineering  
However, in the area of conceptual modeling, it seems that current Object Oriented Analysis methods put most emphasis on the structural aspects of the "IS A"-relationship while inheritance and sharing  ...  Decision criteria on the use of generalization/specialization are discussed and a formal taxonomy of processes corresponding to the generalization/specialization hierarchy is presented.  ...  In the following section it is argued that in the area of conceptual modeling the generalization/specialization and role concepts must be treated very carefully.  ...

On the representation of roles in object-oriented and conceptual modelling

Friedrich Steimann
2000 Data & Knowledge Engineering  
and the objects that engage in them.  ...  The duality of objects and relationships is so deeply embedded in our thinking that almost all modelling languages include it as a fundamental distinction.  ...  Object-oriented design and implementation LODWICK ODW ICK is intended to be an exploratory language for object-oriented modelling with roles at the conceptual level.  ...

Introduction to the Generic Special Issue

Charles H. P. Zuckerman
2021 Language in society  
Generics'--and 'generic reference'--should be a key analytic for understanding the relation between language and the 'social'. Generics 'express general claims about kinds and categories' (  ...  order as the kinds and categories that underlie and are produced by 'semiotic ontologies' (Kockelman 2013) ; or whether our understanding of conceptual categories is itself modeled on our use of generic  ...  We might wonder, for example, whether the kinds to which generics refer are discursive objects, always linguistically mediated in time, or whether they are conceptual ones; whether they are of the same  ...

Functional and Structural Integration without Competence Overstepping in Structured Semantic Knowledge Base System

Marek Krótkiewicz, Krystian Wojtkiewicz
2014 Journal of Logic, Language and Information  
It was one of the reasons that logic has been founded as the universal language of mathematics and formalized communication in more extensive sense.  ...  Natural language processing in the context of logics or information processing is ineffective, not to say pointless in the means of certainty.  ...  Unlike in Object-Oriented approach the language has been developed along with application and modeling methodology.  ...

Conceptual Modelling versus Semantic Web: the two sides of the same coin?

Oscar Pastor, Joan Fons, Victoria Torres, Vicente Pelechano
2004 The Web Conference  
The required conceptual primitives are presented, including those data and functional more conventional primitives, and those navigation and presentation more specific of Web Appls.  ...  In any case, the set of relevant conceptual primitives has to be properly represented. In this paper both approaches are studied as two different strategies to solve a common problem.  ...  Generalization/specialization conceptual primitives include the specification of roles as specialization mechanisms that gets activated only in periods of a given object live.  ...

Handling Conceptual Multidimensional Models Using XML through DTDs [chapter]

Enrique Medina, Sergio Luján-Mora, Juan Trujillo
2002 Lecture Notes in Computer Science  
In this paper, we present how to handle MD models by using the eXtensible Markup Language (XML) through a Document Type Denition (DTD) and the eXtensible Stylesheet Language Transformations (XSLT).  ...  In the last years, several approaches have been proposed to easily capture main multidimensional (MD) properties at the conceptual level.  ...  Finally, in Section 4 we present our conclusions and future works. 2 Object-Oriented Multidimensional Modeling In this section, we summarize how an OO MD model, based on the Unied Modeling Language (  ...

Automatically generating object models from natural language analysis

Hector G. Perez-Gonzalez, Jugal K. Kalita
2002 Companion of the 17th annual ACM SIGPLAN conference on Object-oriented programming, systems, languages, and applications - OOPSLA '02  
This set of methods maximizes analysis process agility, promotes reusability and constitutes a valuable tool in the learning process of object thinking.  ...  Our goal is to enable rapid production of static and dynamic object models from natural language description of problems. Rapid modeling is achieved through automation of analysis tasks.  ...  The research project is sponsored by Universidad Autonoma de San Luis Potosi and PROMEP-SEP, Mexico, as part of Phd studies scholarship.  ...

The OO-binary relationship model : A truly object oriented conceptual model [chapter]

O. Troyer
1991 Lecture Notes in Computer Science  
In this paper we show that is possible to turn such a conventional conceptual model (in particular the Binary Relationship Model) into a truly object oriented conceptual model which combines the assets  ...  Conventional conceptual models like the Binary Relationship Model (also known as NIAM) or the Entity-Relationship Model do not fit well with the promising object oriented database systems.  ...  This generalization/specialization mechanism allows to abstract away the detailed differences of several class descriptions and to factor out the commonalities as a common superclass.  ...
