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…

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…

Interactive Argumentation Support for Invasion Biology
Developing a good, new argument is not an easy task. In real-world argumentation scenarios, arguments presented in texts (e.g. scientific publications) often constitute the end result of a long and tedious process. A lot of work on computational argumentation has focused on detecting, analyzing, and aggregating these products of argumentation processes, i.e. argumentative texts. In this project, we adopt a complementary perspective: we aim to develop an argumentation machine that supports users in and during}the argumentation process in a scientific context, enabling them to follow ongoing argumentation in a scientific community and to develop their own arguments. To achieve this ambitious goal, we will focus on a particular phase of the scientific argumentation process, namely the initial phase of claim or hypothesis development. According to Toulmin (1986), the starting point of an argument is a claim, and also data that serves as a basis for the claim. In scientific argumentation, a carefully developed and thought-through hypothesis (which we see as Toulmin’s “claim” in a scientific context) is often crucial for researchers to be able to conduct a successful study and, in the end, present a new, high-quality finding or argument. Thus, an initial hypothesis needs to be specific enough that a researcher can test it based on data, but, at the same time, it should also relate to and extend previous general claims made in the community. In this project, we investigate how argumentation machines can (i) represent concrete and more abstract knowledge on hypotheses and their underlying concepts, (ii) automatically compute semantic relations between hypotheses made in scientific publications, and between hypotheses and datasets, and (iii) interactively support a user in developing her own hypothesis based on these resources.

AgriSem: Semantic Web Technologies for Agricultural Data Interoperability
This project aims to enhance and improve the interoperability of agricultural data in Egypt collected and coordinated by CLAES. To achieve this goal, we are going first to apply a number of steps from the data management life cycle to revise the collected data and its associated metadata. After that we are planning to semantically model and enrich these data to allow data integration and reuse. Semantic web technologies can provide a common structured representation of information gathered from real-time sensors as well as from non-real time sources such as producer and retail systems. Data integration is becoming one of the major issues in agriculture. Consequently semantic web technologies are starting to play a more important role.

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…
