Within forest growth modeling LOGIT models are used to predict individual tree mortality. In this paper we present, Multi-Layer Perceptron, Learning Vector Quantization and Cascade Correlation networks as different formalisms for mortality predictions. The data set for parameterizing the LOGIT model and training the different neural network types comes from(More)
Playing is an essential part of human culture, even more so nowadays with computer-based games. Gaming is also regarded as an effective means to transfer knowledge and spark interest in a particular topic. This family of games is referred to as educational games and serious games.

In contrast to other user-interfaces for art-databases, we created the explorARTorium to compare artworks along different dimensions without having to rely on textual information that excludes people without sophisticated knowledge(More)

A considerable number of Learning Games have been published over the last years. Since there are no clear guidelines for developers, they may not always meet the learner's expectations. Games are a powerful mediator for learning, but flaws in planning and design can have a negative effect on their potential. This paper describes the design of two Serious(More)
In recent years, the number of data collections that are publicly available via the Internet has dramatically increased. Web based semantic databases like Wikipedia derivate DbPedia extend the functionality of Wikipedia by allowing semantic annotations to the information that is usually in form of free text. Since these data collections also cover broad(More)
The perception of art is a subjective affair - being influenced by our feelings, education and cultural background. Contrary, the study of art history uses formal methods to classify artworks. This discrepancy often poses a risk of being insurmountable -- especially for users without prior knowledge of art history. The concept of social tagging provides the(More)
