    Abstract
    Due to the advances in information retrieval in the past decades, search engines have become extremely efficient at acquiring useful sources in response to a user's query. However, for more prolonged and complex information seeking tasks, these search engines are not as well suited. During complex information seeking tasks, various stages may occur, which imply varying support needs for users. However, the implications of theoretical information seeking models for concrete search user interfaces (SUI) design are unclear, both at the level of the individual features and of the whole interface. Guidelines and design patterns for concrete SUIs, on the other hand, provide recommendations for feature design, but these are separated from their role in the information seeking process. This chapter addresses the question of how to design SUIs with enhanced support for the macro-level process, first by reviewing previous research. Subsequently, we outline a framework for complex task support, which explicitly connects the temporal development of complex tasks with different levels of support by SUI features. This is followed by a discussion of concrete system examples which include elements of the three dimensions of our framework in an exploratory search and sensemaking context. Moreover, we discuss the connection of navigation with the search-oriented framework. In our final discussion and conclusion, we provide recommendations for designing more holistic SUIs which potentially evolve along with a user's information seeking process.

    Abstract
    We present an overview of the NTCIR Math Tasks organized during NTCIR-10, 11, and 12. These tasks are primarily dedicated to techniques for searching mathematical content with formula expressions. In this chapter, we first summarize the task design and introduce test collections generated in the tasks. We also describe the features and main challenges of mathematical information retrieval systems and discuss future perspectives in the field.

    Abstract
    This paper discusses the use of wiki technology to provide a navigation structure for a collection of newspaper clippings. We overview the architecture of the wiki, discuss the navigation structure and pose the question: is the navigation structure an index, and if so, what type, or is it just a linkage structure or topic map. Does such a distinction really matter? Are these definitions in reality function based?

    Abstract
    Several authors emphasize the need for a change in classification theory due to the influence of a dogmatic and monistic ontology supported by an outdated essentialism. These claims tend to focus on the fallibility of knowledge, the need for a pluralistic view, and the theoretical burden of observations. Regardless of the legitimacy of these concerns, there is the risk, when not moderate, to fall into the opposite relativistic extreme. Based on a narrative review of the literature, we aim to reflectively discuss the theoretical foundations that can serve as a basis for a realist position supporting pluralistic ontological classifications. The goal is to show that, against rather conventional solutions, objective scientific-based approaches to natural classifications are presented to be viable, allowing a proper distinction between ontological and taxonomic questions. Supported by critical scientific realism, we consider that such an approach is suitable for the development of ontological Knowledge Organization Systems (KOS). We believe that ontological perspectivism can provide the necessary adaptation to the different granularities of reality.

    Abstract
    COVID-19 is an unprecedented global health crisis that will have immeasurable consequences for our economic and social well-being. Tedros Adhanom Ghebreyesus, the director general of the World Health Organization, stated "We're not just fighting an epidemic; we're fighting an infodemic". Currently, there is no robust scientific basis to the existing definitions of false information used in the fight against the COVID-19infodemic. The purpose of this paper is to demonstrate how the use of a novel taxonomy and related model (based upon a conceptual framework that synthesizes insights from information science, philosophy, media studies and politics) can produce new scientific definitions of mis-, dis- and malinformation. We undertake our analysis from the viewpoint of information systems research. The conceptual approach to defining mis-,dis- and malinformation can be applied to a wide range of empirical examples and, if applied properly, may prove useful in fighting the COVID-19 infodemic. In sum, our research suggests that: (i) analyzing all types of information is important in the battle against the COVID-19 infodemic; (ii) a scientific approach is required so that different methods are not used by different studies; (iii) "misinformation", as an umbrella term, can be confusing and should be dropped from use; (iv) clear, scientific definitions of information types will be needed going forward; (v) malinformation is an overlooked phenomenon involving reconfigurations of the truth.

    Abstract
    Cataloging practices, as exemplified by the five user tasks of the IFLA Library Reference Model, can support information literacy practices. The six frames of the Framework for Information Literacy for Higher Education are used as lenses to examine the user tasks. Two themes emerge from this examination: context matters, and catalogers must tailor bibliographic descriptions to meet users' expectations and information needs. Catalogers need to solicit feedback from various user communities to reform cataloging practices to remain current and viable. Such conversations will enrich the catalog and enhance (reclaim?) its position as a primary tool for research and learning. Supplemental data for this article is available online at https://doi.org/10.1080/01639374.2021.1939828.

    Abstract
    The initial dimensions extracted by latent semantic analysis (LSA) of a document-term matrixhave been shown to mainly display marginal effects, which are irrelevant for informationretrieval. To improve the performance of LSA, usually the elements of the raw document-term matrix are weighted and the weighting exponent of singular values can be adjusted.An alternative information retrieval technique that ignores the marginal effects is correspon-dence analysis (CA). In this paper, the information retrieval performance of LSA and CA isempirically compared. Moreover, it is explored whether the two weightings also improve theperformance of CA. The results for four empirical datasets show that CA always performsbetter than LSA. Weighting the elements of the raw data matrix can improve CA; however,it is data dependent and the improvement is small. Adjusting the singular value weightingexponent often improves the performance of CA; however, the extent of the improvementdepends on the dataset and the number of dimensions.

    Abstract
    We consider use of ontological background knowledge in intelligent information systems and analyze directions of their reduction in compliance with specifics of particular user task. Such reduction is aimed at simplification of knowledge processing without loss of significant information. We propose methods of generation of task thesauri based on domain ontology that contain such subset of ontological concepts and relations that can be used in task solving. Combinatorial optimization is used for minimization of task thesaurus. In this approach, semantic similarity estimates are used for determination of concept significance for user task. Some practical examples of optimized thesauri application for semantic retrieval and competence analysis demonstrate efficiency of proposed approach.

    Abstract
    The content of master's programs accredited by the American Library Association was examined to assess the status of knowledge organization (KO) as a subject in current training. Data collected show that KO remains very visible in a majority of programs, mainly in the form of required and electives courses focusing on descriptive cataloging, classification, and metadata. Observed tendencies include, however, the recent elimination of the required KO course in several programs, the reality that one third of KO electives listed in course catalogs have not been scheduled in the past three years, and the fact that two-thirds of those teaching KO specialize in other areas of information science.

    Abstract
    Die Informationswissenschaft, eine Disziplin ohne Theorie, ohne Bezugsrahmen und ohne Klärung ihres Grundbegriffes. Zahlreiche FachvertreterInnen der Informationswissenschaft bereiten erst recht das Feld für Hate Speech und Fake News vor - mit ihrem ungeklärten (Un)begriff der "Information", - mit ihrer Forderung nach "Informationskompetenz", ein Terrain, das eigentlich der Bibliothekswissenschaft zusteht, - mit ihrer Theorielosigkeit, - mit ihrer unkritischen Ablehnung einer ernsthaften Auseinandersetzung sowie - mit ihrem ungeklärten Domänenverständnis.

    Auf der im März 2021 abgehaltenen (virtuellen) "16th International Symposium of Information Science" ("ISI 2021", Regensburg 8. März -10.März 2021) wurde nochmals nachdrücklich auf die domänenspezifische, fast mit Alleinstellungsanspruch versehene "Informationskompetenz" (Information Literacy) der Bibliotheks- und Informationswissenschaft hingewiesen. Erneut wurden "Zukunftsdiskurse" zu "Informationskompetenz und Demokratie" angekündigt und "Positionspapiere" zur Informationskompetenz und Informationskompetenzvermittlung präsentiert (D. Cetta, J. Griesbaum, T. Mandl, E. Montanari: Positionspapiere. Informationskompetenz und Informationskompetenzvermittlung: Aktueller Stand und Perspektiven. Hildesheim 2019).

    Abstract
    Informationskompetenz in den Bibliotheken und in der Informationswissenschaft. Es ist erschreckend, dass im Zeitalter der vieldiskutierten "Desinformationen" und "Fake News" im Medienbereich der einzige Beitrag der Informationswissenschaft in der Betonung einer irgendwie ausgestalteten "Informationskompetenz", manchmal ergänzt um eine ebenso imaginäre "Medienkompetenz" besteht. Man möchte sich gern zum verbindlichen Entscheider darüber erklären, was wahre und falsche Information, was Hate Speech und Fakten sind. Der Türöffner dafür soll das bibliothekarisch besetzte Feld der "Informationskompetenz" sein, dass man nunmehr für den Gesamtbereich der "Information" besetzen möchte. Die ursprüngliche Beschränkung der bibliothekarischen Domäne der Informationskompetenz auf eine berufsrelevante Vermittlung von InformationsSUCHkompetenz wird dafür geopfert. Der Ursprung des Begriffes "Informationskompetenz" liegt im Bibliotheksbereich und sollte dort beheimatet bleiben.

    Abstract
    Information als "Wissen in Aktion" zu definieren, scheint der Informationswissenschaft zu reichen. Und das in einer Welt, wie das Fachportal woxiwon (https://synonyme.woxikon.de/synonyme/information.php) ausweist, bei über 460 Synonyma für den Begriff "Information", die in fast dreißig Gruppen geclustert sind. Cluster 1: "Aufmerksamkeit" mit den Dimensionen der Nutzererwartungen "Aktualität", "Werbung", "Schlagzeilen" sowie "Provokation durch Fake & Klatsch". Cluster 2: "Verbundenheit" Cluster 3: "Gemeinsamkeit" Cluster 4: "Intellektuelle Leistung"

    Abstract
    The paper examines the development of facet analysis as a methodology and the role it plays in building classifications and other knowledge-organization tools. The use of categorical analysis in areas other than library and information science is also considered. The suitability of the faceted approach for humanities documentation is explored through a critical description of the FATKS (Facet Analytical Theory in Managing Knowledge Structure for Humanities) project carried out at University College London. This research focused on building a conceptual model for the subject of religion together with a relational database and search-and-browse interfaces that would support some degree of automatic classification. The paper concludes with a discussion of the differences between the conceptual model and the vocabulary used to populate it, and how, in the case of religion, the choice of terminology can create an apparent bias in the system.

    Abstract
    A systematic literature review is carried out, detailing the research topics and the methods and techniques used in information science in studies published between 2000 and 2019. The results obtained allow us to affirm that there is no consensus on the core topics of information science, as these evolve and change dynamically in relation to other disciplines, and with the dominant social and cultural contexts. With regard to the research methods and techniques, it can be stated that they have mostly been adopted from social sciences, with the addition of numerical methods, especially in the fields of bibliometric and scientometric research.

    Abstract
    I wonder if you would consider an English perspective on the exchange between Bernd Jörs and Hermann Huemer. In my career in the independent education sector I can recall many discussions and Government reports about cross-curricular issues such as logical reasoning and critical thinking, In the IB system this led to the inclusion in the Diploma of "Theory of Knowledge." In the UK we had "key skills" and "critical thinking." One such key skill is what we now call "information literacy." "In his parody of Information literacy, Dr Jörs seems to have confused a necessary condition for a sufficient condition. The fact that information competence may be necessary for serious academic study does not of course make it sufficient. When that is understood the joke about the megalomaniac rather loses its force. (We had better pass over the rant which follows, the sneer at "earth sciences" and the German prejudice towards Austrians)."

    Abstract
    In the blooming area of Internet technology, the concept of Internet-of-Things (IoT) holds a distinct position that interconnects a large number of smart objects. In the context of social IoT (SIoT), the argument of trust and reliability is evaluated in the presented work. The proposed framework is divided into two blocks, namely Verification Block (VB) and Evaluation Block (EB). VB defines various ontology-based relationships computed for the objects that reflect the security and trustworthiness of an accessed service. While, EB is used for the feedback analysis and proves to be a valuable step that computes and governs the success rate of the service. Support vector machine (SVM) is applied to categorise the trust-based evaluation. The security aspect of the proposed approach is comparatively evaluated for DDoS and malware attacks in terms of success rate, trustworthiness and execution time. The proposed secure ontology-based framework provides better performance compared with existing architectures.

    Abstract
    Im Mittelpunkt dieses Beitrags steht das 2016 von der Association of College & Research Libraries (ACRL) veröffentlichte Framework for Information Literacy for Higher Education, dessen Kernideen und Entwicklung aus Vorläufern wie den 2000 von der ACRL publizierten Information Literacy Competency Standards for Higher Education heraus skizziert werden. Die Rezeptionsgeschichte dieser Standards im deutschen Sprachraum wird vor dem Hintergrund der Geschichte ihrer (partiellen) Übersetzung nachgezeichnet und hieraus das Potenzial abgeleitet, das die nun vorliegende vollständige Übersetzung des Framework ins Deutsche für eine zeitgemäße Förderung von Informationskompetenz bietet. Die vielfältigen Herausforderungen einer solchen Übersetzung werden durch Einblicke in die Übersetzungswerkstatt exemplarisch reflektiert.
