Privacy Defense

User privacy on the internet is an important and unsolved problem. So far, no sufficient and comprehensive solution has been proposed that helps a user to protect his or her privacy while using the internet. Data is collected and assembled by numerous service providers. Solutions so far focused on the side of the service providers … Read more

The Smell of Fear

While the physiological response of humans to emotional events or stimuli is well-investigated for many modalities (like EEG, skin resistance, …), surprisingly little is known about the exhalation of so-called Volatile Organic Compounds (VOCs) at quite low concentrations in response to such stimuli. VOCs are molecules of relatively small mass that quickly evaporate or sublimate … Read more


enviPath is both, a database and a prediction system, for the microbial biotransformation of organic environmental contaminants. The database provides the possibility to store and view experimentally observed biotransformation pathways, and supports the annotation of pathways with experimental and environmental conditions. The pathway prediction system provides different relative reasoning models to predict likely biotransformation pathways … Read more


Machine Learning methods and algorithms are often highly modular in the sense that they rely on a large number of subalgorithms that are in principle interchangeable. For example, it is often possible to use various kinds of pre- and post-processing and various base classifiers or regressors as components of the same modular approach. We propose … Read more


Boolean matrix decomposition is a method to obtain a compressed representation of a matrix with Boolean entries. BMaD (Boolean Matrix Decomposition Framework) is a modular framework, written in Java, that unifies several Boolean matrix decomposition algorithms, and provide methods to evaluate their performance. The main advantages of the framework are its modular approach and hence the flexible … Read more


The overall objective of the EU FP7 project OpenTox was to develop a framework that provides a unified access to toxicity data, (Q)SAR models, procedures supporting validation and additional information that helps with the interpretation of (Q)SAR predictions. The OpenTox framework has been developed as an open source project to optimize the dissemination and impact, to allow … Read more


To fully support the analysis of complex and structured data, new efficient computational methods  and suitable interfaces for data exploration have to be developed. Moreover, it is desirable to perform all tasks in the knowledge discovery process, from pre-processing to post-processing, on the basis of query languages. Inductive query languages should allow handling patterns/models as … Read more
