- ItemPROBADO 3D - Integration von 3D-Objekten in Digitale Bibliotheken. Ein Dienstleistungsangebot für Architektur und Ingenieurwesen zur Erschließung und Bereitstellung von Multimediadokumenten(2011) Blümel, Ina; Sens, Irina[no abstract available]
- ItemÜberblick über den aktuellen Stand der Forschungsberichterstattung: Integration, Standardisierung, verteilte Informationssysteme(Karlsruhe : KIT, 2015) Riechert, Mathias; Tobias, Regine; Heller, Lambert; Blümel, Ina; Biesenbender, SophieDieses Diskussionspapier gibt einen Überblick über die Entwicklung der Forschungsberichterstattung im Wissenschaftssystem. 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.
- ItemEntwicklung eines Verfahrens zur automatischen Sammlung, Erschließung und Bereitstellung multimedialer Open-Access-Objekte mittels der Infrastruktur von Wikimedia Commons und Wikidata(Zenodo, 2014) Blümel, Ina; Cartellieri, Simone; Heller, Lambert; Wartena, Christian[no abstract available]
- ItemScience 2.0 & open science in higher education(Hannover : Technische Informationsbibliothek, 2016) Blümel, Ina; Heck, Tamara; Heise, Christian; Peters, Isabella; Scherp, Ansgar; Weisel, Luzian[no abstract available]
- 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.
- ItemCoScience - Gemeinsam forschen und publizieren mit dem Netz(Hannover : Technische Informationsbibliothek, 2014-05-24) Arning, Ursula; Bargheer, Margo; Blümel, Ina; Dietze, Stefan; Fenner, Martin; Friesike, Sascha; Hauschke, Christian; Heise, Christian; Heller, Lambert; Hohmann, Tina; Jäschke, Robert; Kleinwechter, Ulrich; Leiß, Caroline; Lemke, Dorothea; König, Mareike; Mehlberg, Martin; Neumann, Janna; Pampel, Heinz; Peters, Isabella; Schmidt, Birgit; Schmitz, Jasmin; Teichert, Astrid; Tullney, Marco; Heller, Lambert; Hochschule HannoverDer Arbeitsalltag von Wissenschaftlerinnen und Wissenschaftlern hat sich in den letzten Jahren dramatisch verändert. Forschen, Schreiben und Publizieren sind mittlerweile stark durch netzbasierte Anwendungen geprägt. Das digitale Zeitalter aber hat nicht nur neue technische Werkzeuge hervorgebracht, sondern auch neue Wege eröffnet, um Wissen zu generieren und zu verbreiten. Dies gilt sowohl innerhalb der akademischen Weltals auch über diese hinaus. Das Arbeiten mit dem Netz stellt unsere bisherigen etablierten wissenschaftlichen Praktiken in Frage. Forschung wird zunehmend vernetzt, kollaborativ, multimedial, trans- bzw. interdisziplinär durchgeführt.
- Item3D@Technische Informationsbibliothek (TIB) : das Projekt PROBADO zeigt effiziente Möglichkeiten zur Suche in 3D-Daten. In: Web Science - die Zukunft des Internets(Hannover : Leibniz Universität Hannover, 2012) Blümel, Ina; Sens, Irinaimmer mehr digitale Wissensobjekte finden Eingang in Bibliotheken. innerhalb der Future Internet Initiative ist die TIB Mitglied der Arbeitsgruppe Internet of Contents, die Fragestellungen rund um die Erschließung und Nutzung von nichttextuellen, insbesondere audiovisuellen Daten in den Blick nimmt. Am Beispiel des Projekts PROBADO zeigen die Autorinnen, wie 3D-Modelle in die bibliothekarische Prozesskette integriert werden können.
- ItemDiscovery and efficient reuse of technology pictures using Wikimedia infrastructures. A proposal(Zenodo, 2016) Heller, Lambert; Blümel, Ina; Cartellieri, Simone; Wartena, ChristianMultimedia objects, especially images and figures, are essential for the visualization and interpretation of research findings. The distribution and reuse of these scientific objects is significantly improved under open access conditions, for instance in Wikipedia articles, in research literature, as well as in education and knowledge dissemination, where licensing of images often represents a serious barrier. Whereas scientific publications are retrievable through library portals or other online search services due to standardized indices there is no targeted retrieval and access to the accompanying images and figures yet. Consequently there is a great demand to develop standardized indexing methods for these multimedia open access objects in order to improve the accessibility to this material. With our proposal, we hope to serve a broad audience which looks up a scientific or technical term in a web search portal first. Until now, this audience has little chance to find an openly accessible and reusable image narrowly matching their search term on first try - frustratingly so, even if there is in fact such an image included in some open access article.
