    Reduced reference image and video quality assessments: review of methods
    (New York, NY : Hindawi Publishing Corp., 2022) Dost, Shahi; Saud, Faryal; Shabbir, Maham; Khan, Muhammad Gufran; Shahid, Muhammad; Lovstrom, Benny
    With the growing demand for image and video-based applications, the requirements of consistent quality assessment metrics of image and video have increased. Different approaches have been proposed in the literature to estimate the perceptual quality of images and videos. These approaches can be divided into three main categories; full reference (FR), reduced reference (RR) and no-reference (NR). In RR methods, instead of providing the original image or video as a reference, we need to provide certain features (i.e., texture, edges, etc.) of the original image or video for quality assessment. During the last decade, RR-based quality assessment has been a popular research area for a variety of applications such as social media, online games, and video streaming. In this paper, we present review and classification of the latest research work on RR-based image and video quality assessment. We have also summarized different databases used in the field of 2D and 3D image and video quality assessment. This paper would be helpful for specialists and researchers to stay well-informed about recent progress of RR-based image and video quality assessment. The review and classification presented in this paper will also be useful to gain understanding of multimedia quality assessment and state-of-the-art approaches used for the analysis. In addition, it will help the reader select appropriate quality assessment methods and parameters for their respective applications.

    Responsible Knowledge Management in Energy Data Ecosystems
    (Basel : MDPI, 2022) Janev, Valentina; Vidal, Maria-Esther; Pujić, Dea; Popadić, Dušan; Iglesias, Enrique; Sakor, Ahmad; Čampa, Andrej
    This paper analyzes the challenges and requirements of establishing energy data ecosystems (EDEs) as data-driven infrastructures that overcome the limitations of currently fragmented energy applications. It proposes a new data- and knowledge-driven approach for management and processing. This approach aims to extend the analytics services portfolio of various energy stakeholders and achieve two-way flows of electricity and information for optimized generation, distribution, and electricity consumption. The approach is based on semantic technologies to create knowledge-based systems that will aid machines in integrating and processing resources contextually and intelligently. Thus, a paradigm shift in the energy data value chain is proposed towards transparency and the responsible management of data and knowledge exchanged by the various stakeholders of an energy data space. The approach can contribute to innovative energy management and the adoption of new business models in future energy data spaces.

    3D@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, Irina
    immer 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.

    A PDF Test-Set for Well-Formedness Validation in JHOVE - The Good, the Bad and the Ugly
    (Zenodo, 2017) Lindlar, Michelle; Tunnat, Yvonne; Wilson, Carl
    Digital preservation and active software stewardship are both cyclical processes. While digital preservation strategies have to be reevaluated regularly to ensure that they still meet technological and organizational requirements, software needs to be tested with every new release to ensure that it functions correctly. JHOVE is an open source format validation tool which plays a central role in many digital preservation workflows and the PDF module is one of its most important features. Unlike tools such as Adobe PreFlight or veraPDF which check against requirements at profile level, JHOVE’s PDF-module is the only tool that can validate the syntax and structure of PDF files. Despite JHOVE’s widespread and long-standing adoption, the underlying validation rules are not formally or thoroughly tested, leading to bugs going undetected for a long time. Furthermore, there is no ground-truth data set which can be used to understand and test PDF validation at the structural level. The authors present a corpus of light-weight files designed to test the validation criteria of JHOVE’s PDF module against “well-formedness”. We conclude by measuring the code coverage of the test corpus within JHOVE PDF validation and by feeding detected inconsistencies of the PDF-module back into the open source development process.

    Functional access to electronic media collections using emulation-as-a-service
    (2014) Bähr, Thomas; Lindlar, Michelle; Rechert, Klaus; Liebetraut, Thomas
    Over the last 30 years the German National Library of Science and Technology (TIB) accumulated a large collection of various electronic media, such as floppies or CD-ROMs. This poster describes both practical workflows as well as technical infrastructure to provide authentic and interactive access to the TIB’s large electronic media collection.

    Linked Heritage – ein europäisches Projekt
    (Berlin : de Gruyter, 2013) Mensing, Petra
    Das Hauptziel des EU-Projektes Linked Heritage1 war die Einspielung von 3 Millionen neuen Datensätzen in die Europeana. Die 38 Projektpartner kamen aus 20 europäischen Ländern plus Israel und Russland. Die Technische Informationsbibliothek (TIB) Hannover stellte für dieses Projekt Metadaten aus dem Kompetenzzentrum für nichttextuelle Materialen sowie aus dem Bereich Forschungsdaten bereit und war an drei der sieben Arbeitspakete2 beteiligt.

    Workflow management of sprints and software tests: Coordination, consensus, and cooperation in the enterprise wiki of the German National Library of Science and Technology
    (New York, NY : International Institute for Science, Technology and Education, 2016) Strobel, Sven
    This paper discusses the workflow management of sprints and software tests at the German National Library of Science and Technology (TIB) and pays special attention to how the enterprise wiki can be used to support forms of group interaction such as coordination, consensus (finding), and cooperation. The enterprise wiki helps to organize who has to do what by when (coordination). At TIB, it essentially supports the project managers in planning, organizing, and controlling the workflows of the project. Moreover, it facilitates and accelerates the decision making within the team (consensus) and helps the team members to share knowledge and develop ideas by editing common documents (cooperation). The workflows for sprints and software tests as well as their management are illustrated by the example of the TIB project relaunching the TIB|AV-Portal. The paper argues that establishing workflows in the wiki makes collaborative working more efficient and easier to handle. This is shown with respect to the team’s coordination, consensus finding, and cooperation in the project. The paper also specifies the TIB concepts for sprints – a method to develop concepts collaboratively – and software tests. The topic discussed here relates to subject areas such as knowledge management and project management and, more specifically, to collaborative working and computer-supported cooperative work.
