RDF Schema (RDFS) and RDF are evolving as the de facto languages for the Semantic Web. Whereas RDFS can be used to define concepts in a domain ontology, RDF can be used to define instances of that ontology. In an attempt to make these modeling languages evolvable and extensible, the current languages lack a clear semantic support. While RDF and RDFS are easy to use, they are hard to understand ...

This paper introduces, and provides a cognitive basis for, a prototype meta-modeling process called ESCAPE. This process involves users Explicitly Stating their own model of an entity of interest, CAPturing an alternative or correct model of that entity and consequently re-Evaluating their own model. The paper shows the model’s implicit, but already well established, use in the software enginee...

Graphical models are used to depict various aspects of enterprise architectures. Process modeling methods in particular have evolved from simple flowcharts to newer methods that include a large number of diagramming symbols, which increases their perceived complexity. To date, two main approaches for the complexity evaluation of conceptual modeling techniques have been proposed: a set of metric...

Multi-level meta-modeling hinges on the precise conceptualization of the instantiation relation between elements of the meta-model and the model. In this paper, we propose a new algebraic instantiation approach, the Dynamic Multi-Layer Algebra. The approach aims to provide a solid algebraic foundation for multi-level meta-modeling, which is easily customizable through different bootstrap elemen...

In a recent Philosophy of Science article Gerhard Schurz proposes meta-inductivistic prediction strategies as a new approach to Hume’s Problem [6]. This comment examines the limitations of Schurz’s approach. It can be proven that the meta-inductivist approach does not work any more if the meta-inductivists have to face an infinite number of alternative predictors. With this limitation it remain...

Despite the recent interest for Model Driven Engineering approaches, the so-called four-layers metamodelling architecture is subject to a lot of debate. The relationship that exists between a model and a metamodel is often called instanceOf, but this terminology, which comes directly from the object oriented technology, is not appropriate for the modelling of similar meta-pyramids in other doma...

Choosing a suitable classifier for a given data set is an important part of a data mining process. Since a large variety of classification algorithms are proposed in literature, nonexperts, as teachers, do not know which method should be used in order to achieve a good pattern. Hence, a recommender service which guide on the process or automatize it is welcome. In this paper, we rely on meta-le...

This position paper presents META-NORD project which develops Nordic and Baltic part of the European open language resource infrastructure. META-NORD works on assembling, linking across languages, and making widely available the basic language resources used by developers, professionals and researchers to build specific products and applications. Goals of the project, overall approach and speci...

This case study discusses variation and formalization strategies for managing technology-use mediation of Web-based groupware technologies in an organizational context. Research and development projects of a multi-national pharmaceutical company entail a close collaboration between many geographically distributed actors. The use of a groupware technology in long term, cross-disciplinary and dis...

This study employed meta-analytic procedures to evaluate the potential validity of a model of planned organizational change. Hypotheses derived from this model focus on the relationships among planned change interventions and three classes of organizational variables, assessing work settings, individual behavior, and organizational outcomes. The aggregated results of 52 evaluations of planned c...
