Current Projects

GFBio (https://www.gfbio.org) is a national infrastructure and contact point for issues concerning research data management and standardization of biological and environmental data. The project was established in 2013 with the main goal is to support scholars in all steps of the data life cycle, from acquisition to archiving and data publication. Five years later, GFBio provides a data portal with access to more than 5 Mio biodiversity metadata files. The majority of this data is linked with primary research data which can be further analyzed in an interactive visualization tool. Furthermore, GFBio is the national contact point for submitting biological data and mediates data archiving in dedicated data centers to ensure sustainable, long-term preservation and publication of research data. In addition, it organizes and supports education and training of scholars on all facets of research data management.

Jena Data Center (JDC)
The Jena Data Center (JDC) at the Friedrich Schiller University Jena is a conglomerate of data repositories belonging to various small to mid-scale biodiversity and ecological projects, that are using BEXIS2 research data management tool. The aim of the data centre is to provide F.A.I.R principles-based data and ensure long-term preservation and availability along with its high-quality descriptive metadata, to facilitate open science and biodiversity conservation. As part of the long-term preservation objective, after the completion of the project tenure, the data centre will integrate the associated BEXIS2 based data repositories within the Jena data centre e-infrastructure so as to ensure the data is available…

Adaptive Semantic Assistants in Online Applications
The rapid growth rate of available textual documents underlines a prominent need for novel approaches to overcome the information overload that knowledge workers are faced with. In such situations, new information filtering and analysis techniques are required to provide end users with information related to their context and task at hand. In cooperation with the Semantic Software Lab at Concordia University in Montréal, Canada (http://www.semanticsoftware.info), we have been developing a new generation of portals that automatically adapt to their users context using novel techniques from the Natural Language Processing (NLP) and Semantic Computing domains. The vision is to extend an…

The CoSRe project of the Friedrich-Schiller-University of Jena investigates how computers can support the entire scientific life cycle. Today in each science computers are needed, not only for the storage of experimental data, but also for generating simulation data and futhermore for the analysis of different kinds of data. Over the internet scientists can work together and can share their results. This collaboration leads to new knowledge and new challenges. To deal with this "flood of information" the complete scientific cycle has to be supported by computers. For more information about CoSRe - please visit the project website http://cosre.c3e.de/

Semantic User Modeling for the Recommendation of Scientific Data
Collaboration with the  Semantic Software Lab, Concordia University, Montréal, Canada Researchers in the medical and life sciences are faced with an increasing abundance of data in scientific repositories. Thus, handling and filtering of data becomes a more and more time-consuming and challenging task. Semantic recommender systems are a new rising research area using underlying knowledge bases, e.g., ontologies in the recommendation process. That allows to present relevant results that go beyond a user’s stored preferences and to include other semantic related terms that are not explicitly mentioned in the user profile. One obstacle for semantic recommendation is the poor description of personalization settings in state-of-the-art user model ontologies. Apart from storing general user interests it is not possible to specify further needs. We aim at the establishment of a formal semantic user model for scientific research objects and its integration and usage in semantic recommender systems.
