    Blockchains and the crypto city
    (it - Information Technology: Vol. 59, No. 6, 2017) Potts, Jason; Rennie, Ellie; Goldenfein, Jake
    Drawing on economic transaction cost theory, this paper explores how blockchain and distributed ledger technology could shift the smart city agenda by altering transaction costs with implications for the coordination of infrastructures and resources. Like the smart city the crypto city utilizes data informatics, but can be coordinated through distributed rather than centralized systems. The data infrastructure of the crypto city can enable civil society to run local public goods and services, and facilitate economic and social entrepreneurship.

    Co-creating digital public services with older citizens: Challenges and opportunities
    (INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft, 2019) Jarke, Juliane; Gerhard, Ulrike; Kubicek, Herbert
    Older citizens are excluded above average from digital public services as they do not meet older adults’ needs and expectations. Yet most digital technologies, designed for an ageing population, reproduce particular images about age and ageing, such as the old age defined by ill health, deficits and limitations or an emphasis on active ageing. Digital public services are no different. We are interested in understanding through what kind of methods older adults may be enabled to become active co-creators of information systems and in so doing may transform our images of an ageing population. The paper is based on a collaborative research project in which older adults co-created a digital neighbourhood guide. We describe a framework of interventions which facilitated the co-creation process and discuss associated challenges and opportunities.

    Designing an ethical technology project with the help of Data Feminism
    (SKILL 2021, 2021) Gleißner, Lea-Kathrin; Bui, Magdalena; Kühn, Fey; Nenninger, Amelie
    Algorithms and new technologies help people in several life situations, but society pays a high price for their advantages. Several scandals occurred recently, showing that algorithms are neither neutral nor fair – quite the contrary: They discriminate people as humans do. One approach to create less biased data science projects is the “Data Feminism” method, presented by Catherine D’Ignazio and Lauren F. Klein in their book of the same title. This paper evaluates how feasible the method can be implemented in student projects based on the experiences four Leipzig students made by trying to implement the method into their project ‘Questioning Street Names Leipzig’. The paper focusses on three main concepts: subjective viewpoints and context, crediting all forms of labour, and building and linking communities through public tagging events, thus opening the academic question for some citizen science help. The project utilizes open data and open data sources such as Wikidata and OpenStreetMap. The authors of “Data Feminism” want to encourage students, as well as academic professionals, to think about their bias in their data and to use the data feminism approach to reduce the impact of them and create more ethical computer science projects.

    Designing Granular Competency Frameworks for Adaptive Learning on the Example of Naïve Bayes Classifiers
    (Proceedings of DELFI Workshops 2022, 2022) Selmanagić, André; Simbeck, Katharina
    Adaptive learning environments that follow a competency-based learning approach require granular, domain-specific competency frameworks (models) for the continuous assessment of a learner’s knowledge and skills as well as for the subsequent personalization of instruction. This case-study describes the iterative creation process for a competency framework in the domain of Naïve Bayes classifiers, including the design principles that led to the framework and the tools used for making it publishable as linked, open data.

    Discover Barrier-free Accessible Locations with the Location Navigator
    (INFORMATIK 2017, 2017) Abicht, Konrad; Ackermann, Simeon; Martin, Michael
    We present the current version of the Location Navigator, which supports users by finding locations in Leipzig, that can be accessed without barriers. Besides this current version of the prototype we present additionally experiences regarding its engineering process and the previously performed conversion of Open Data provided by the registered association Behindertenverband Leipzig e.V. (BVL). Our vision of the underlying data is an inter-commune data network, in order to support persons with special needs and, furthermore, to apply developments such as the Location Navigator to other municipalities. For this purpose, RDF will be used for the representation and linking of data in the future. Besides the presentation of the Location Navigator, we sketch some approaches we evaluated during the creation of the respective data model.

    Dynamic indoor navigation and orientation system for people with impairments
    (Mensch und Computer 2020 - Tagungsband, 2020) Richter, Julia; Lorenz, Jeanine; Costantino, Maria; Traubinger, Verena; Tauchmann, Nico; Graichen, Thomas; Heinkel, Ulrich
    Assistive technologies play an important role on the way to an inclusive society. At this point, mobile indoor navigation for persons with impairments is a task far from being solved. Existing studies mainly focus on outdoor navigation, are closed source and closed data or are aimed at one single target group only, and consequently represent isolated solutions. Therefore, this study reports a design for an indoor navigation system for persons with different impairments, following the idea of open source and open data to facilitate a long-term and sustainable solution everyone can contribute to. The proposed system components are discussed, which include novel indoor mapping methodologies, user profile-specific indoor extensions for routing, navigation instructions and rendering, as well as an accurate technology for indoor positioning. Both modularity of the proposed system as well as the design-for-all approach allow, for the first time, the general application of mobile navigation addressing a variety of impairments.

    Including Data Management in Research Culture Increases the Reproducibility of Scientific Results
    (INFORMATIK 2022, 2022) Riedel,Christian; Geßner,Hendrik; Seegebrecht,Anja; Ayon,Safial Islam; Chowdhury,Shafayet Hossen; Engbert,Ralf; Lucke,Ulrike
    Reproducible research results are among the pillars of sustainable science, and considerable progress has been achieved in this direction recently. However, there is much room for improvement across the research communities. Here we analyze the reproducibility of 108 publications from an interdisciplinary Collaborative Research Center on applied mathematics in various scientific fields. Based on a previous reproducibility study in hydrology, we identify the rate of reproducible scientific results and why reproducibility fails. We identify the main problems that hinder reproducible results and relate them to previous interventions targeting the research culture of reproducible scientific findings. Thus, the success of our measures can be estimated, and specific recommendations for future work can be derived. In our study, the number of publications that allow for at least partly reproducible research results increased over time. However, we see an ongoing need for directives and support in research data management among research communities since issues concerning data accessibility and quality limit the reproducibility of scientific results. We argue that our results are representative of other interdisciplinary research areas.
