- ItemSurvey: Open Science in Higher Education(Zenodo, 2017) Heck, Tamara; Blümel, Ina; Heller, Lambert; Mazarakis, Athanasios; Peters, Isabella; Scherp, Ansgar; Weisel, LuzianBased on a checklist that was developed during a workshop at OER Camp 2016 and presented as a Science 2.0 conference 2016 poster [1], we conducted an online survey among university teachers representing a sufficient variety of subjects. The survey was online from Feb 6th to March 3rd 2017. We got 360 responses, whereof 210 were completes, see raw data [2]. The poster is presented at Open Science Conference, 21.-22.3.2017, Berlin.

Dabei werden aktuelle Entwicklungen von integrierten Forschungsinformationssystemen und aktuelle Standardisierungsinitiativen aufgezeigt und ein Einblick in ein Umsetzungsprojekt eines verteilten Systems gegeben. Der Beitrag schließt in mit einer Diskussion von Weiterentwicklungsszenarien verteilter Forschungsinformationssysteme im Wis-senschaftssystem.
- ItemThe quest for research information(Amsterdam : Elsevier, 2014) Blümel, Ina; Dietze, Stefan; Heller, Lambert; Jäschke, Robert; Mehlberg, MartinResearch information, i.e., data about research projects, organisations, researchers or research outputs such as publications or patents, is spread across the web, usually residing in institutional and personal web pages or in semi-open databases and information systems. While there exists a wealth of unstructured information, structured data is limited and often exposed following proprietary or less-established schemas and interfaces. Therefore, a holistic and consistent view on research information across organisational and national boundaries is not feasible. On the other hand, web crawling and information extraction techniques have matured throughout the last decade, allowing for automated approaches of harvesting, extracting and consolidating research information into a more coherent knowledge graph. In this work, we give an overview of the current state of the art in research information sharing on the web and present initial ideas towards a more holistic approach for boot-strapping research information from available web sources.
- ItemEfficient retrieval of 3D building models using embeddings of attributed subgraphs(Institut für Informatik II, Universität Bonn, 2011) Wessel, R.; Ochmann, S.; Vock, R.; Blümel, Ina; Klein, R.We present a novel method for retrieval and classification of 3D building models that is tailored to the specific requirements of architects. In contrast to common approaches our algorithm relies on the interior spatial arrangement of rooms instead of exterior geometric shape. We first represent the internal topological building structure by a Room Connectivity Graph (RCG). Each room is characterized by a node. Connections between rooms like e.g. doors are represented by edges. Nodes and edges are additionally assigned attributes reflecting room and edge properties like e.g area or window size. To enable fast and efficient retrieval and classification with RCGs, we transform the structured graph representation into a vector-based one. We first decompose the RCG into a set of subgraphs. For each subgraph, we compute the similarity to a set of codebook graphs. Aggregating all similarity values finally provides us with a single vector for each RCG which enables fast retrieval and classification. For evaluation, we introduce a classification scheme that was carefully developed following common guidelines in architecture.We finally provide comprehensive experiments showing that the introduced subgraph embeddings yield superior performance compared to state-of-the-art graph retrieval approaches.

- ItemTowards an Open Research Knowledge Graph(Zenodo, 2018) Auer, Sören; Blümel, Ina; Ewerth, Ralph; Garatzogianni, Alexandra; Heller,, Lambert; Hoppe, Anett; Kasprzik, Anna; Koepler, Oliver; Nejdl, Wolfgang; Plank, Margret; Sens, Irina; Stocker, Markus; Tullney, Marco; Vidal, Maria-Esther; van Wezenbeek, WilmaThe document-oriented workflows in science have reached (or already exceeded) the limits of adequacy as highlighted for example by recent discussions on the increasing proliferation of scientific literature and the reproducibility crisis. Despite an improved and digital access to scientific publications in the last decades, the exchange of scholarly knowledge continues to be primarily document-based: Researchers produce essays and articles that are made available in online and offline publication media as roughly granular text documents. With current developments in areas such as knowledge representation, semantic search, human-machine interaction, natural language processing, and artificial intelligence, it is possible to completely rethink this dominant paradigm of document-centered knowledge exchange and transform it into knowledge-based information flows by representing and expressing knowledge through semantically rich, interlinked knowledge graphs. The core of the establishment of knowledge-based information flows is the distributed, decentralized, collaborative creation and evolution of information models, vocabularies, ontologies, and knowledge graphs for the establishment of a common understanding of data and information between the various stakeholders as well as the integration of these technologies into the infrastructure and processes of search and knowledge exchange in the research library of the future. By integrating these information models into existing and new research infrastructure services, the information structures that are currently still implicit and deeply hidden in documents can be made explicit and directly usable. This revolutionizes scientific work because information and research results can be seamlessly interlinked with each other and better mapped to complex information needs. As a result, scientific work becomes more effective and efficient, since results become directly comparable and easier to reuse. In order to realize the vision of knowledge-based information flows in scholarly communication, comprehensive long-term technological infrastructure development and accompanying research are required. To secure information sovereignty, it is also of paramount importance to science – and urgency to science policymakers – that scientific infrastructures establish an open counterweight to emerging commercial developments in this area. The aim of this position paper is to facilitate the discussion on requirements, design decisions and a minimum viable product for an Open Research Knowledge Graph infrastructure. TIB aims to start developing this infrastructure in an open collaboration with interested partner organizations and individuals.
- ItemProfile, Studiengänge, Fakultäten: Bottom-Up-Entwicklung eines VIVO an der Hochschule Hannover(Zenodo, 2017) Blümel, InaEinblicke in ein studentisches VIVO-Projekt an der Fakultät III der Hochschule Hannover (HsH). Basierend auf einer Analyse der Eigendarstellungen aus Websiten und der sonstigen Selbstmarketing-Aktivitäten der Wissenschaftler/innen der der Fakultät III der HsH sollten die Bedarfe der Forschenden im Hinblick auf FIS-Visualisierungen ermittelt werden. Dazu wurden die Wissenschafter/innen eingehend befragt. Als Ergebnis des Projektes entstand ein VIVO, dass nicht von der Hochschulleitung initiiert wurde, sondern direkt aus Eigeninitiative der Fakultät entstand.

- ItemVIVO Lab at the German National Library of Science and Technology: Review and outlook(Zenodo, 2016) Walther, Tatiana; Blümel, Ina; Heller, LambertThis poster gives an overview about past, current and future activities of the VIVO Lab – a sub-group of the Open Science Lab at the German National Library of Science and Technology (TIB). In the past there have been several corporate projects and implementations around VIVO, including the past corporate VIVO project – VIVO for the TIB, which was complemented with the additional features (VIVOPath and VIVO Deutsches Handbuch). The current subject area of the VIVO Lab covers, among other things, the alignment of the Research Core Dataset (KDSF) to the VIVO-ISF and the integration of the national standard into VIVO, which is planned to be applied as a new model of the TIB VIVO for internal assessment and reporting.
