AquaDiva D01 - Semantic Technologies for Scientific Data management and Text Mining (SemDaTe)
The Collaborative Research Centre AquaDiva (CRC 1076), funded by the German Research Foundation (DFG), focuses on the important roles of water (Aqua) and biodiversity (Diva) for shaping the structure, properties, and functions of the subsurface. This project aims to answer fundamental questions about the Earth’s Critical Zone (CZ) that begins below the highest density of plant roots (~0.3 meters) and extends down into the first aquifers (~100 meters): What biota live there? How do they interact with and reflect on their environment? and How do they reflect surface properties? In cooperation with the research group of Prof. Dr. Udo Hahn…

Completed Projects

BioDialog: Intercultural Dialog through Biodiversity Informatics
Ein Kooperationsprojekt der Universität Jena mit der Assiut University und der Ain Shams University, Ägypten und der Sfax University, Tunesien This project serves to prepare a more ambitious three-year project aiming to bring together two vital topics: data management on the one hand and biodiversity research on the other hand. The BioDialog project has the following main objectives: It aims firstly, to establish a scientific exchange, founded on regional expertise which allows understanding biodiversity and biodiversity informatics practices in their specific local context. Biodiversity and biodiversity informatics are common phenomena. However, they have different effects in different contexts which cannot…
