Many learning methods ignore domain knowledge in synthesis of concept approximation. We propose to use hierarchical schemes for learning approximations of complex concepts from experimental data using inference diagrams based on domain knowledge. Our solution is based on the rough set and rough mereological approaches. The effectiveness of the proposed approach is performed and evaluated on art...

Graphs are a commonly used formalism for modeling many different kinds of static and dynamic data. In many applications, data modeling can be improved by using hierarchically structured graphs. But, while there already exist hierarchical graph data models, no generalpurpose hierarchical graph data model exists yet, which unifies common features of these domain-specific models. In this paper, we...

During the post-Darwinian history of taxonomy, the Linnaeän hierarchy has maintained its role as a means for representing hierarchical taxononaic relationships. During the same period, the principle of descent has tallen on an increasingly important role as the basis for reformulated versions of fundamental taxonomic concepts and principles. Early in this history, the principle of descent provi...

Appropriate and eecient representations of domains, objects, and scenes are an important issue in the elds of geometric modelling , numerical simulation, and visualiza-tion. Though various techniques have been developed and are successfully used as single-purpose solutions, there is still some lack of comprehensive approaches that allow to base modelling, simulation, and visualization on the sa...
