    Cloud4health – On effective ways to deal with sensitive patient data in a secure Cloud environment
    (PARS-Mitteilungen: Vol. 31, Nr. 1, 2014) Claus, Steffen; Schwichtenberg, Horst; Laufer, Julian; Berger, Florian
    The cloud4health project researches secondary analysis of clinical patient data, such as surgeryand discharge-reports in a secure and trusted Cloud infrastructure. Given the data’s sensitive nature, a main emphasis rests on guaranteeing its confidentiality during the course of the analysis. The paper outlines infrastructure developments of the first year of the cloud4health project and highlights requirements towards a secure Cloud environment. The first solution architecture is sketched and the lifecycle of data processing is presented.

    Generating Structured Data by Nontechnical Experts in Research Settings
    (i-com: Vol. 17, No. 1, 2018) Breitenfeld, Andre; Berger, Florian; Hong, Ming-Tung; Mackeprang, Maximilian; Müller-Birn, Claudia
    Semantic technologies provide meaning to information resources in the form of machine-accessible structured data. Research over the past two decades has commonly focused on tools and interfaces for technical experts, leading to various usability problems regarding users unfamiliar with the underlying technologies – so-called nontechnical experts. Existing approaches to semantic technologies consider mostly consumers of structured data and leave out the creation perspective. In this work, we focus on the usability of creating structured data from textual resources, especially the creation of relations between entities. The research was conducted in collaboration with scholars from the humanities. We review existing research on the usability of semantic technologies and the state of the art of annotation tools to identify shortcomings. Subsequently we use the knowledge gained to propose a new interaction design for the creation of relations between entities to create structured data in the subject-predicate-object form. We implemented our interaction design and conducted a user study which showed that the proposal performed well, making it a contribution to enhance the overall usability in this field. However, this research provides an example of how technically sophisticated technology needs to be “translated” to make it usable for nontechnical experts. We need to extend this perspective in the future by providing more insight into the internal functioning of semantic technologies.

    Toward Cyber-Physical Research Practice based on Mixed Reality
    (Mensch und Computer 2017 - Workshopband, 2017) Hoffmeister, Anouk; Berger, Florian; Pogorzhelskiy, Michael; Zhang, Guangtao; Zwick, Carola; Müller-Birn, Claudia
    Research practice has benefited greatly from advances in technology. Yet, disciplines handling physical objects still experience several limitations when connecting analog research practices to digital resources. Utilizing recent developments in mixed reality technology, we propose a digital research environment that overcomes these limitations. We present a soft- and hardware prototype that blends analog annotation practices with its digital counterpart. Our approach advances the state of the art by enabling real-time handling of digital representations by manipulating actual physical objects. We discuss our future work concepts of blending objects and augmenting information using mixed reality technologies, and connecting object-centered research practices to online data sources.
