  Lin, F.-T.: Drawing a knowledge map of smart city knowledge in academia.
  In: Knowledge organization. 46(2019) no.6, S.419-438.
  
  Abstract: This research takes the academic articles in the Web of Science's core collection database as a corpus to draw a series of knowledge maps, to explore the relationships, connectivity, dis-tribution, and evolution among their keywords with respect to smart cities in the last decade. Beyond just drawing a text cloud or measuring their sizes, we further explore their texture by iden-tifying the hottest keywords in academic articles, construct links between and among them that share common keywords, identify islands, rocks, reefs that are formed by connected articles-a metaphor inspired by Ong et al. (2005)-and analyze trends in their evolution. We found the following phenomena: 1) "Internet of Things" is the most frequently mentioned keyword in recent research articles; 2) the numbers of islands and reefs are increas-ing; 3) the evolutions of the numbers of weighted links have frac-tal-like structure; and, 4) the coverage of the largest rock, formed by articles that share a common keyword, in the largest island is converging into around 10% to 20%. These phenomena imply that a common interest in the technology of smart cities has been emerging among researchers. However, the administrative, social, economic, and cultural issues need more attention in academia in the future.

  Clavier, V.: Knowledge organization, data and algorithns : the new era of visual representation.
  In: Knowledge organization. 46(2019) no.8, S.615-621.
  
  Abstract: This article shows how visual representations have progressively taken the lead over classical language-based models of knowledge organization (KO). The paper adopts a theoretical and historical perspective and focuses on the consequences of the changes in the volume of data generated by data production on the KO models. Until now, data visualization tools have been used mainly by researchers with expertise in textual data processing or in computational linguistics. But now, these tools are accessible to a greater number of users. Thus, there are new issues at stake for KO, other professions and institutions for gathering data that contribute to defining new standards and KO representations.

  Kraker, P. ; Schramm, M. ; Kittel, C.: Open knowledge maps : visuelle Literatursuche basierend auf den Prinzipien von Open Science.
  In: Mitteilungen der Vereinigung Österreichischer Bibliothekarinnen und Bibliothekare. 72(2019) H.2-4, S.460-477.
  
  Abstract: Die Wissenschaft befindet sich in einer Auffindbarkeitskrise. Obwohl durch die Open Access-Bewegung Forschungsergebnisse besser zugänglich geworden sind, wird ein signifikanter Teil der Outputs nicht nachgenutzt. Einen großen Anteil an der Krise haben die Tools, die für die Literatursuche verwendet werden. Angesichts von drei Millionen Veröffentlichungen pro Jahr sind klassische Ansätze, wie etwa listenbasierte Suchmaschinen, nicht mehr ausreichend. Open Knowledge Maps hat es sich zum Ziel gesetzt, die Auffindbarkeit wissenschaftlichen Wissens zu verbessern. Dafür betreibt die gemeinnützige Organisation aus Österreich die weltweit größte visuelle Suchmaschine für Forschung. Das Grundprinzip besteht darin, Wissenslandkarten für die Literatursuche zu nutzen. Diese geben einen Überblick über ein Forschungsfeld und ermöglichen so einen schnelleren Einstieg in die Literatur. Open Knowledge Maps basiert auf den Prinzipien von Open Science: Inhalte, Daten und Software werden unter einer freien Lizenz veröffentlicht. Dadurch entsteht eine offene, wiederverwendbare Infrastruktur; Lock-In-Effekte, wie sie bei proprietären Systemen auftreten, werden vermieden. Open Knowledge Maps arbeitet seit Beginn eng mit Bibliotheken und BibliothekarInnen als ExpertInnen für Wissensorganisation und -verwaltung zusammen. Im Rahmen eines konsortialen Fördermodells werden Bibliotheken nun eingeladen, das System stärker mitzugestalten - unter anderem bei wichtigen Zukunftsthemen wie der besseren Auffindbarkeit von Datensätzen.

  Wu, I.-C. ; Vakkari, P.: Effects of subject-oriented visualization tools on search by novices and intermediates.
  In: Journal of the Association for Information Science and Technology. 69(2018) no.12, S.1428-1445.
  
  Abstract: This study explores how user subject knowledge influences search task processes and outcomes, as well as how search behavior is influenced by subject-oriented information visualization (IV) tools. To enable integrated searches, the proposed WikiMap + integrates search functions and IV tools (i.e., a topic network and hierarchical topic tree) and gathers information from Wikipedia pages and Google Search results. To evaluate the effectiveness of the proposed interfaces, we design subject-oriented tasks and adopt extended evaluation measures. We recruited 48 novices and 48 knowledgeable users, that is, intermediates, for the evaluation. Our results show that novices using the proposed interface demonstrate better search performance than intermediates using Wikipedia. We therefore conclude that our tools help close the gap between novices and intermediates in information searches. The results also show that intermediates can take advantage of the search tool by leveraging the IV tools to browse subtopics, and formulate better queries with less effort. We conclude that embedding the IV and the search tools in the interface can result in different search behavior but improved task performance. We provide implications to design search systems to include IV features adapted to user levels of subject knowledge to help them achieve better task performance.

  Abstract: Datenvisualisierungen sind ein wichtiges Werkzeug, um Inhalte und Muster in Datensätzen zu erkennen und ermöglichen so auch Laien den Zugang zu der Information, die in Datensätzen steckt. Data Visualization Literacy ist die Kompetenz, Datenvisualisierungen zu lesen, zu verstehen, zu hinterfragen und herzustellen. Data Visulaization Literacy ist daher eine wichtige Kompetenz der Informationsgesellschaft. Im Auftrag des Bundesrates hat das Bundesamt für Kommunikation BAKOM die Strategie "Digitale Schweiz" entwickelt. Die Strategie zeigt auf, wie die fortschreitende Digitalisierung genutzt und die Schweiz zu einer Informationsgesellschaft entwickelt werden soll. In der vorliegenden Arbeit wird untersucht, inwiefern die Strategie "Digitale Schweiz" die Förderung von Data Visualization Literacy in der Bevölkerung unterstützt. Dazu werden die Kompetenzen der Data Visualization Literacy ermittelt, Kompetenzstellen innerhalb des Bildungssystems benannt und die Massnahmen der Strategie in Bezug auf Data Visualization Literacy überprüft.

  Osinska, V. ; Kowalska, M. ; Osinski, Z.: ¬The role of visualization in the shaping and exploration of the individual information space : part 1.
  In: Knowledge organization. 45(2018) no.7, S.547-558.
  
  Abstract: Studies on the state and structure of digital knowledge concerning science generally relate to macro and meso scales. Supported by visualizations, these studies can deliver knowledge about emerging scientific fields or collaboration between countries, scientific centers, or groups of researchers. Analyses of individual activities or single scientific career paths are rarely presented and discussed. The authors decided to fill this gap and developed a web application for visualizing the scientific output of particular researchers. This free software based on bibliographic data from local databases, provides six layouts for analysis. Researchers can see the dynamic characteristics of their own writing activity, the time and place of publication, and the thematic scope of research problems. They can also identify cooperation networks, and consequently, study the dependencies and regularities in their own scientific activity. The current article presents the results of a study of the application's usability and functionality as well as attempts to define different user groups. A survey about the interface was sent to select researchers employed at Nicolaus Copernicus University. The results were used to answer the question as to whether such a specialized visualization tool can significantly augment the individual information space of the contemporary researcher.

  Salaba, A. ; Mercun, T. ; Aalberg, T.: Complexity of work families and entity-based visualization displays.
  In: Cataloging and classification quarterly. 56(2018) no.7, S.628-652.
  
  Abstract: Conceptual modeling of bibliographic data, including the FR models and the consolidated IFLA LRM, has provided an opportunity to shift focus to entities and relationships and to support hierarchical work-based exploration of bibliographic information. This paper reports on a study examining the complexity of a work's bibliographic family data and user interactions with data visualizations, compared to traditional displays. Findings suggest that the FRBR-based visual bibliographic information system supports work families of different complexities more equally than a traditional system. Differences between the two systems also show that the FRBR-based system was more effective especially for related-works and author-related tasks.

  Aletras, N. ; Baldwin, T. ; Lau, J.H. ; Stevenson, M.: Evaluating topic representations for exploring document collections.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.1, S.154-167.
  
  Abstract: Topic models have been shown to be a useful way of representing the content of large document collections, for example, via visualization interfaces (topic browsers). These systems enable users to explore collections by way of latent topics. A standard way to represent a topic is using a term list; that is the top-n words with highest conditional probability within the topic. Other topic representations such as textual and image labels also have been proposed. However, there has been no comparison of these alternative representations. In this article, we compare 3 different topic representations in a document retrieval task. Participants were asked to retrieve relevant documents based on predefined queries within a fixed time limit, presenting topics in one of the following modalities: (a) lists of terms, (b) textual phrase labels, and (c) image labels. Results show that textual labels are easier for users to interpret than are term lists and image labels. Moreover, the precision of retrieved documents for textual and image labels is comparable to the precision achieved by representing topics using term lists, demonstrating that labeling methods are an effective alternative topic representation.

  Mercun, T. ; Zumer, M. ; Aalberg, T.: Presenting bibliographic families using information visualization : evaluation of FRBR-based prototype and hierarchical visualizations.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.2, S.392-411.
  
  Abstract: Since their beginnings, bibliographic information systems have been displaying results in the form of long, textual lists. With the development of new data models and computer technologies, the need for new approaches to present and interact with bibliographic data has slowly been maturing. To investigate how this could be accomplished, a prototype system, FrbrVis1, was designed to present work families within a bibliographic information system using information visualization. This paper reports on two user studies, a controlled and an observational experiment, that have been carried out to assess the Functional Requirements for Bibliographic Records (FRBR)-based against an existing system as well as to test four different hierarchical visual layouts. The results clearly show that FrbrVis offers better performance and user experience compared to the baseline system. The differences between the four hierarchical visualizations (Indented tree, Radial tree, Circlepack, and Sunburst) were, on the other hand, not as pronounced, but the Indented tree and Sunburst design proved to be the most successful, both in performance as well as user perception. The paper therefore not only evaluates the application of a visual presentation of bibliographic work families, but also provides valuable results regarding the performance and user acceptance of individual hierarchical visualization techniques.

  Zhu, Y. ; Yan, E. ; Song, I.-Y..: ¬The use of a graph-based system to improve bibliographic information retrieval : system design, implementation, and evaluation.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.2, S.480-490.
  
  Abstract: In this article, we propose a graph-based interactive bibliographic information retrieval system-GIBIR. GIBIR provides an effective way to retrieve bibliographic information. The system represents bibliographic information as networks and provides a form-based query interface. Users can develop their queries interactively by referencing the system-generated graph queries. Complex queries such as "papers on information retrieval, which were cited by John's papers that had been presented in SIGIR" can be effectively answered by the system. We evaluate the proposed system by developing another relational database-based bibliographic information retrieval system with the same interface and functions. Experiment results show that the proposed system executes the same queries much faster than the relational database-based system, and on average, our system reduced the execution time by 72% (for 3-node query), 89% (for 4-node query), and 99% (for 5-node query).

  Wen, B. ; Horlings, E. ; Zouwen, M. van der ; Besselaar, P. van den: Mapping science through bibliometric triangulation : an experimental approach applied to water research.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.3, S.724-738.
  
  Abstract: The idea of constructing science maps based on bibliographic data has intrigued researchers for decades, and various techniques have been developed to map the structure of research disciplines. Most science mapping studies use a single method. However, as research fields have various properties, a valid map of a field should actually be composed of a set of maps derived from a series of investigations using different methods. That leads to the question of what can be learned from a combination-triangulation-of these different science maps. In this paper we propose a method for triangulation, using the example of water science. We combine three different mapping approaches: journal-journal citation relations (JJCR), shared author keywords (SAK), and title word-cited reference co-occurrence (TWRC). Our results demonstrate that triangulation of JJCR, SAK, and TWRC produces a more comprehensive picture than each method applied individually. The outcomes from the three different approaches can be associated with each other and systematically interpreted to provide insights into the complex multidisciplinary structure of the field of water research.

  Abstract: Die Bayerische Staatsbibliothek (BSB) zählt mit ihrem Bestand von knapp 11 Mio. Bänden zu den bedeutendsten Universalbibliotheken der Welt. Bereits 1,2 Mio. Werke sind digitalisiert, was die BSB zur größten digitalen Kulturinstitution in Deutschland macht. Dieser digitale Bestand umfasst vorwiegend urheberrechtsfreie Werke vom 8. bis ins 20. Jahrhundert, von der mittelalterlichen Bibelhandschrift bis zur Boulevardzeitung der 1920er-Jahre. Diese Vielfalt des zu digitalisierenden schriftlichen Kulturerbes und das hohe Tempo der Massendigitalisierung in den letzten Jahren haben ihren Preis - die inhaltliche Erschließung der Werke hinkt hinterher, insbesondere bei Werken, die nicht mittels Optical Character Recognition-Verfahren (OCR) automatisiert maschinenlesbar transformiert und zugänglich gemacht werden können. Dies gilt insbesondere für mittelalterliche Handschriften, Alte Druck- und Spezialbestände. Deshalb blieb auch der reichhaltige, in diesen Werken verborgene Bildbestand für den Nutzer weitestgehend verborgen und konnte lediglich durch das Durchblättern am Bildschirm entdeckt werden. Dies war Motivation für die Bayerische Staatsbibliothek, gemeinsam mit dem Fraunhofer Heinrich-Hertz-Institut in Berlin ein System zur ähnlichkeitsbasierten Bildsuche aufzubauen, welches sämtliche Bildinhalte aller 1,2 Mio. Digitalisate automatisch identifiziert. Hierbei werden mittels morphologischer Verfahren Bilder aus den Buchseiten extrahiert, die danach aufgrund von Farb- und Kantenmerkmalen klassifiziert werden. Bilder "ohne Informationswert" werden mit Hilfe von Methoden aus dem Bereich des maschinellen Lernens herausgefiltert. Damit konnten aus den digitalisierten Werken der BSB bislang mehr als 43 Mio. einzelne Bilder identifiziert werden, die mittels einer hochperformanten Suchmaschine über eine frei verfügbare Web-Applikation dem Anwender direkt zur Verfügung stehen. Dank der Vielfalt und Reichhaltigkeit der indexierten Bestände spricht dieses Angebot nicht nur Historiker und Buchwissenschaftler an, sondern Interessierte aus den unterschiedlichsten Fachrichtungen. Die Ähnlichkeitssuche stellt dabei unbekannte, ungewöhnliche und oftmals überraschende Bezüge zwischen unterschiedlichsten Werken her.

  Yan, B. ; Luo, J.: Filtering patent maps for visualization of diversification paths of inventors and organizations.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.6, S.1551-1563.
  
  Abstract: In the information science literature, recent studies have used patent databases and patent classification information to construct network maps of patent technology classes. In such a patent technology map, almost all pairs of technology classes are connected, whereas most of the connections between them are extremely weak. This observation suggests the possibility of filtering the patent network map by removing weak links. However, removing links may reduce the explanatory power of the network on inventor or organization diversification. The network links may explain the patent portfolio diversification paths of inventors and inventing organizations. We measure the diversification explanatory power of the patent network map, and present a method to objectively choose an optimal tradeoff between explanatory power and removing weak links. We show that this method can remove a degree of arbitrariness compared with previous filtering methods based on arbitrary thresholds, and also identify previous filtering methods that created filters outside the optimal tradeoff. The filtered map aims to aid in network visualization analyses of the technological diversification of inventors, organizations, and other innovation agents, and potential foresight analysis. Such applications to a prolific inventor (Leonard Forbes) and company (Google) are demonstrated.

  Minkov, E. ; Kahanov, K. ; Kuflik, T.: Graph-based recommendation integrating rating history and domain knowledge : application to on-site guidance of museum visitors.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.8, S.1911-1924.
  
  Abstract: Visitors to museums and other cultural heritage sites encounter a wealth of exhibits in a variety of subject areas, but can explore only a small number of them. Moreover, there typically exists rich complementary information that can be delivered to the visitor about exhibits of interest, but only a fraction of this information can be consumed during the limited time of the visit. Recommender systems may help visitors to cope with this information overload. Ideally, the recommender system of choice should model user preferences, as well as background knowledge about the museum's environment, considering aspects of physical and thematic relevancy. We propose a personalized graph-based recommender framework, representing rating history and background multi-facet information jointly as a relational graph. A random walk measure is applied to rank available complementary multimedia presentations by their relevancy to a visitor's profile, integrating the various dimensions. We report the results of experiments conducted using authentic data collected at the Hecht museum. An evaluation of multiple graph variants, compared with several popular and state-of-the-art recommendation methods, indicates on advantages of the graph-based approach.

  Zhang, Y. ; Zhang, G. ; Zhu, D. ; Lu, J.: Scientific evolutionary pathways : identifying and visualizing relationships for scientific topics.
  In: Journal of the Association for Information Science and Technology. 68(2017) no.8, S.1925-1939.
  
  Abstract: Whereas traditional science maps emphasize citation statistics and static relationships, this paper presents a term-based method to identify and visualize the evolutionary pathways of scientific topics in a series of time slices. First, we create a data preprocessing model for accurate term cleaning, consolidating, and clustering. Then we construct a simulated data streaming function and introduce a learning process to train a relationship identification function to adapt to changing environments in real time, where relationships of topic evolution, fusion, death, and novelty are identified. The main result of the method is a map of scientific evolutionary pathways. The visual routines provide a way to indicate the interactions among scientific subjects and a version in a series of time slices helps further illustrate such evolutionary pathways in detail. The detailed outline offers sufficient statistical information to delve into scientific topics and routines and then helps address meaningful insights with the assistance of expert knowledge. This empirical study focuses on scientific proposals granted by the United States National Science Foundation, and demonstrates the feasibility and reliability. Our method could be widely applied to a range of science, technology, and innovation policy research, and offer insight into the evolutionary pathways of scientific activities.

  Abstract: An event is a specific occurrence involving participants, which is a typed, n-ary association of entities or other events, each identified as a participant in a specific semantic role in the event (Pyysalo et al. 2012; Linguistic Data Consortium 2005). Event types may vary across domains. Representing relationships between events can facilitate the understanding of knowledge in complex systems (such as economic systems, human body, social systems). In the simplest form, an event can be represented as Entity A Entity B. This paper evaluates several knowledge organization and visualization models and tools, such as concept maps (Cmap), topic maps (Ontopia), network analysis models (Gephi), and ontology (Protégé), then proposes an event relationship model that aims to integrate the strengths of these models, and can represent complex knowledge expressed in events and their relationships.

  Choi, I.: Visualizations of cross-cultural bibliographic classification : comparative studies of the Korean Decimal Classification and the Dewey Decimal Classification.

  Abstract: The changes in KO systems induced by sociocultural influences may include those in both classificatory principles and cultural features. The proposed study will examine the Korean Decimal Classification (KDC)'s adaptation of the Dewey Decimal Classification (DDC) by comparing the two systems. This case manifests the sociocultural influences on KOSs in a cross-cultural context. Therefore, the study aims at an in-depth investigation of sociocultural influences by situating a KOS in a cross-cultural environment and examining the dynamics between two classification systems designed to organize information resources in two distinct sociocultural contexts. As a preceding stage of the comparison, the analysis was conducted on the changes that result from the meeting of different sociocultural feature in a descriptive method. The analysis aims to identify variations between the two schemes in comparison of the knowledge structures of the two classifications, in terms of the quantity of class numbers that represent concepts and their relationships in each of the individual main classes. The most effective analytic strategy to show the patterns of the comparison was visualizations of similarities and differences between the two systems. Increasing or decreasing tendencies in the class through various editions were analyzed. Comparing the compositions of the main classes and distributions of concepts in the KDC and DDC discloses the differences in their knowledge structures empirically. This phase of quantitative analysis and visualizing techniques generates empirical evidence leading to interpretation.
