abstract = {Ontologies have become an established data model for conceptualizing knowledge entities and describing semantic relationships between them. They are used to model the concepts of specific domains and are widespread in the areas of the semantic web, digital libraries and multimedia database management. To gain the most possible benefit from this data model, it is important to offer adequate visualizations, so that users can easily acquire the knowledge. Most ontology visualization techniques are based on hierarchical or graph-based visualization metaphors. This may result in information-loss, visual clutter, cognitive overload or context-loss. In this paper we describe a new approach of ontology visualization technique called \textit{SemaSun} that is based on the sunburst visualization metaphor. We improved this metaphor, which is naturally designed for displaying hierarchical data, to the tasks of displaying multiple inheritance and semantic relations. This approach also offers
incremental ontology exploring to reduce the cognitive load without losing the informational context.},

abstract = {The following paper describes the conceptual design of an Intelligent Exploration System (IES) that offers a user-adapted graphical environment of web-based knowledge repositories, to support and optimize the explorative learning. The paper starts with a short definition of learning by exploring and introduces the Intelligent Tutoring System and Semantic Technologies for developing such an Intelligent Exploration System. The IES itself will be described with a short overview of existing learner or user analysis methods, visualization techniques for exploring knowledge with semantics technology and the explanation of the characteristics of adaptation to offer a more efficient learning environment.},

abstract = {The enhancement of the individual knowledge is a basic need that came up with changes in our society, whereas the process of learning disappears more and more. In the recent past the disappearance of a predefined learning process was named ambient learning, which came up to cope the changing need of every time and everywhere learning. Learning contents get more structure by new technologies like semantics, which specifies and defines more the semantic structure and with it the meaning of information. Users working with information system are confronted with different processes for getting the required information. The following paper introduces a new visualization technique, which uses the everyday processes of information search for imparting knowledge. The visualization technique utilizes the surplus of semantics to encourage the process of ambient learning.},
