Towards an Open Research Knowledge Graph
The 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.
VIVO-DE-Extension und VIVO-KDSF – Ontologien für den deutschsprachigen Raum
Der Aufbau einer deutschsprachigen Version der Fachinformationssystem-Software VIVO ist nicht so einfach, da sich auf allen Ebenen des Systems sprachspezifische Elemente finden -- von der Anzeige bis hin zu den enthaltenen Ontologien -- und da eine direkte Übersetzung aufgrund kultureller Unterschiede in den Wissenschaftslandschaften oft nicht möglich ist. In dieser Präsentation werden die entsprechenden Aktivitäten der deutschsprachigen VIVO-Community vorgestellt und es wird zur Beteiligung aufgerufen.
Voraussetzungen und Anwendungspotentiale einer präzisen Sacherschließung aus Sicht der Wissenschaft
Thesen: Intellektuelle und automatisierte Sacherschließung müssen ineinandergreifen – tief erschlossene Kerne, die für eine Skalierung durch automatisierte Methoden optimiert sind. Die Qualität der Sacherschließung in Titeldaten lässt sich durch hochqualitative Normdaten verbessern. Automatisierung: Nachhaltige Mischung von statistischen/heuristischen und semantischen/logischen Methoden. Eine Transformation hin zu interoperablen Semantic-Web-Formaten öffnet Möglichkeiten zur Qualitätssteigerung durch erleichterte Nachnutzung in den Fachcommunities.

Knowledge organization systems in mathematics and in libraries
Based on the project activities planned in the context of the Specialized Information Service for Mathematics (TIB Hannover, FAU Erlangen, L3S, SUB Göttingen) we give an overview over the history and interplay of subject cataloguing in libraries, the development of computerized methods for metadata processing and the rise of the Semantic Web. We survey various knowledge organization systems such as the Mathematics Subject Classification, the German Authority File, the clustering International Authority File VIAF, and lexical databases such as WordNet and their potential use for mathematics in education and research. We briefly address the difference between thesauri and ontologies and the relations they typically contain from a linguistic perspective. We will then discuss with the audience how the current efforts to represent and handle mathematical theories as semantic objects can help deflect the decline of semantic resource annotation in libraries that has been predicted by some due to the existence of highly performant retrieval algorithms (based on statistical, neuronal, or other big data methods). We will also explore the potential characteristics of a fruitful symbiosis between carefully cultivated kernels of semantic structure and automated methods in order to scale those structures up to the level that is necessary in order to cope with the amounts of digital data found in libraries and in (mathematical) research (e.g., in simulations) today.
