Abstract

Converting UDC numbers manually to a complex format such as the one mentioned above is an unrealistic expectation; supporting building these representations, as far as possible automatically, is a well-founded requirement. An additional advantage of this approach is that the existing records could also be processed and converted. In my dissertation I would like to prove also that it is possible to design and implement an algorithm that is able to convert pre-coordinated UDC numbers into the introduced format by identifying all their elements and revealing their whole syntactic structure as well. In my dissertation I will discuss a feasible way of building a UDC-specific XML schema for describing the most detailed and complicated UDC numbers (containing not only the common auxiliary signs and numbers, but also the different types of special auxiliaries). The schema definition is available online at: http://piros.udc-interpreter.hu#xsd. The primary goal of my research is to prove that it is possible to support building, retrieving, and analyzing UDC numbers without compromises, by taking the whole syntactic richness of the scheme by storing the UDC numbers reserving the meaning of pre-coordination. The research has also included the implementation of a software that parses UDC classmarks attended to prove that such solution can be applied automatically without any additional effort or even retrospectively on existing collections.

Abstract

The increasing popularity of the Internet and social media is creating new and unique challenges for parents and adolescents regarding the boundaries between parental control and adolescent autonomy in virtual spaces. Drawing on developmental psychology and Communication Privacy Management (CPM) theory, we conduct a qualitative study to examine the challenge between parental concern for adolescent online safety and teens' desire to independently regulate their own online experiences. Analysis of 12 parent-teen pairs revealed five distinct challenges: (a) increased teen autonomy and decreased parental control resulting from teens' direct and unmediated access to virtual spaces, (b) the shift in power to teens who are often more knowledgeable about online spaces and technology, (c) the use of physical boundaries by parents as a means to control virtual spaces, (d) an increase in indirect boundary control strategies such as covert monitoring, and (e) the blurring of lines in virtual spaces between parents' teens and teens' friends.

Abstract

This study is a citation analysis of a set of theses and dissertations in the Ohio State University's online catalog, for which the author-assigned keywords and cataloger-assigned Library of Congress Subject Headings (LCSH) are known. Correlations are sought between the types and ages of resources cited and the number of unique keywords and unique LCSH that were found. The author presents results found in three general discipline areas: arts and humanities, the social sciences, and science, technology, engineering, and medicine.

Abstract

We present a methodological approach, called Group Informatics, for understanding the social connections that are created between members of technologically mediated groups. Our methodological approach supports focused thinking about how online groups differ from each other, and diverge from their face-to-face counterparts. Group Informatics is grounded in 5 years of empirical studies of technologically mediated groups in online learning, software engineering, online political discourse, crisis informatics, and other domains. We describe the Group Informatics model and the related, 2-phase methodological approach in detail. Phase one of the methodological approach centers on a set of guiding research questions aimed at directing the application of Group Informatics to new corpora of integrated electronic trace data and qualitative research data. Phase 2 of the methodological approach is a systematic set of steps for transforming electronic trace data into weighted social networks.

Abstract

Purpose The purpose of this paper is to examine participation in online social platforms consisting of information exchange, social network interactions, and political deliberation. Despite the proven benefits of online participation, the majority of internet users read social media data but do not directly contribute, a phenomenon called lurking. Design/methodology/approach A survey was administered electronically to 507 participants and consisted of ten sections in a questionnaire to gather data on the relationship between online participation and the following variables: anonymity, social value orientation, motivations, and participation in offline activities, as well as the internet's political influence and personality traits. Findings Findings show that users with high levels of participation also identify themselves, report higher levels of extroversion, openness, and activity outside the internet, the motivations being an intermediary variable in the relationship between the variables value. Originality/value The study shows that participation in online social platforms is not only related to personality traits, but they are impacted by the nature of the motivations that drive them to participate in the particular social platform, as well as by the interest toward the specific topic, or the type or nature of the social group with whom they are communicating.

Abstract

Purpose The purpose of this paper is to examine some drivers of users' participation in online social question-and-answer (Q&A) communities based on social cognitive theory and then identify the underlying mechanism of this process. Design/methodology/approach This study developed a research model to test the proposed hypotheses, and an online survey was employed to collected data. Totally, 313 valid responses were collected, and partial least squares structural equation modeling was adopted to analyze these data. Findings This study empirically finds that the outcome expectations (personal outcome expectations and knowledge self-management outcome expectations) are positively related to participation in online social Q&A communities. At the same time, users' self-efficacy positively influences their participation behaviors. It can not only directly motivate users' participation, but also indirectly promote participation behaviors through the two dimensions of outcome expectations. Besides, perceived expertise and perceived similarity are two positive and significant environmental elements affecting users' participation. Originality/value This study extends the understanding about how participation behaviors will be motivated in the context of online social Q&A communities. Drawing on the social cognitive theory, constructs were established based on the features of these communities. Meanwhile, some mediating effects in the motivating process were also discussed.

Abstract

Am 29. und 30. Oktober 2009 fand in der Königlichen Bibliothek in Den Haag das zweite internationale UDC-Seminar zum Thema "Classification at a Crossroad" statt. Organisiert wurde diese Konferenz - wie auch die erste Konferenz dieser Art im Jahr 2007 - vom UDC-Konsortium (UDCC). Im Mittelpunkt der diesjährigen Veranstaltung stand die Erschließung des World Wide Web unter besserer Nutzung von Klassifikationen (im Besonderen natürlich der UDC), einschließlich benutzerfreundlicher Repräsentationen von Informationen und Wissen. Standards, neue Technologien und Dienste, semantische Suche und der multilinguale Zugriff spielten ebenfalls eine Rolle. 135 Teilnehmer aus 35 Ländern waren dazu nach Den Haag gekommen. Das Programm umfasste mit 22 Vorträgen aus 14 verschiedenen Ländern eine breite Palette, wobei Großbritannien mit fünf Beiträgen am stärksten vertreten war. Die Tagesschwerpunkte wurden an beiden Konferenztagen durch die Eröffnungsvorträge gesetzt, die dann in insgesamt sechs thematischen Sitzungen weiter vertieft wurden.

Abstract

We propose, in this work, a method of medical image indexing and research by exploiting their own digital component. We represent the image digital component by a vector of characteristics what we will call: numerical signature of the image. Using the Gabor wavelets, each image of the training medical base is indexed and represented by its characteristics (texture). We thus will build (in offline) a numerical data base of signature. This enables us (in online) to carry out a numerical search for similarity compared to a request image. In order to evaluate the performances we tested our application on a training mammography images basis. The results obtained show well that the representation of the digital component of the images proves to be significant as regards search for information in imagery.

Abstract

Purpose Online knowledge communities make great contributions to global knowledge sharing and innovation. Resource tagging approaches have been widely adopted in such communities to describe, annotate and organize knowledge resources mainly through users' participation. However, it is unclear what causes the adoption of a particular resource tagging approach. The purpose of this paper is to identify factors that drive users to use a hybrid social tagging approach. Design/methodology/approach Technology acceptance model and social cognitive theory are adopted to support an integrated model proposed in this paper. Zhihu, one of the most popular online knowledge communities in China, is taken as the survey context. A survey was conducted with a questionnaire and collected data were analyzed through structural equation model. Findings A new hybrid social resource tagging approach was refined and described. The empirical results revealed that self-efficacy, perceived usefulness (PU) and perceived ease of use exert positive effect on users' attitude. Moreover, social influence, PU and attitude impact significantly on users' intention to use a hybrid social resource tagging approach. Originality/value Theoretically, this study enriches the type of resource tagging approaches and recognizes factors influencing user adoption to use it. Regarding the practical parts, the results provide online information system providers and designers with referential strategies to improve the performance of the current tagging approaches and promote them.

Abstract

In den letzten Jahren wurde die Vermittlung von lnformationskompetenz (und manchmal darüber hinausgehend die Medienkompetenz) als ein neuer zentraler Baustein des Berufsbildes der Bibliothekarin/des Bibliothekars entwickelt. Ausgehend von den Führungen durch die Bibliothek und Schulungen in der Handhabung des Katalogs gehören mittlerweile neben der Katalogrecherche zur Informationskompetenzvermittlung auch die Datenbankrecherche und die Recherche in Suchdiensten nach frei im Netz verfügbaren Informationen. Aber nicht nur die Suchdienste, auch die recherchierbaren Inhalte haben sich erweitert. Ebenso hat man didaktisch konzeptionell viele Überlegungen angestellt und diese pädagogisch auf der Höhe der Zeit in einem stimmigen Konzept zusammengefasst, der Teaching Library. Hierzu gehören beispielsweise Grundsätze wie - Verschlankung des zu vermittelnden Inhalts - zusätzliche Visualisierung der Information ist besser als alleinige Übermittlung durch Sprache - selbst Ausprobieren bringt den Teilnehmern/Teilnehmerinnen mehr Lernerfolge als Inhalte und Lösungen lediglich vorgeführt zu bekommen Darüber hinaus bemühen sich viele Bibliotheken, die Inhalte von Schulungen zusätzlich in Tutorials und Selbstlernkursen auf der Homepage der Bibliothek anzubieten und auch sonst Anleitungstexte dort zu platzieren, wo Benutzer Defizite in der Handhabung von Suchdiensten und des Wissens über Fachrecherche haben könnten, beispielsweise direkt beim Online-Katalog (OPAC). Das macht Sinn, erreicht man doch durch Präsenzveranstaltungen aus verschiedenen Gründen nur einen Bruchteil der Benutzer und vermittelt nur teilweise die notwendigen Schlüsselqualifikationen zur Recherche, die für ein solides und effektives wissenschaftliches Arbeiten vonnöten wären. Online-Kurse und -Informationen zur Recherche sind hochverfügbar, die Benutzer können sie durcharbeiten oder abrufen, wann immer sie das Bedürfnis verspüren, Wissenslücken über die Recherche auszugleichen. Aber stimmt dieses positive Bild mit der Realität überein? Erreichen die Online-Tutorials ihre Zielgruppen? Werden die richtigen Methoden zur Umsetzung der Inhalte gewählt, so dass dieses eLearning effektiver ist als eine Vermittlung in der Face-to-face-Situation einer Schulung? Welche Anforderungen, welche Möglichkeiten, welche Hemmnisse gibt es hier? Diese Checkliste soll zumindest das Feld der Möglichkeiten und Widrigkeiten umreißen und Umsetzungsmöglichkeiten aufzeigen, wie man - angemessen an die jeweiligen Zielgruppen - Informationskompetenz als Schlüsselqualifikation online vermitteln kann.

Abstract

In order to enhance the use of Universal Decimal Classification (UDC) numbers in information retrieval, the authors have represented classification with multilingual thesaurus descriptors and implemented this solution in an automated way. The authors illustrate a solution implemented in a BiblioPhil library system. The standard formats used are UNIMARC for subject authority records (i.e. the UDC-based multilingual thesaurus) and MARC XML support for data transfer. The multilingual thesaurus was built according to existing standards, the constituent parts of the classification notations being used as the basis for search terms in the multilingual information retrieval. The verbal equivalents, descriptors and non-descriptors, are used to expand the number of concepts and are given in Romanian, English and French. This approach saves the time of the indexer and provides more user-friendly and easier access to the bibliographic information. The multilingual aspect of the thesaurus enhances information access for a greater number of online users

Abstract

This study examines the aggregate bandwagon effect of popularity cues on the viewership of online user-generated videos. Cognitive and behavioral theories of information processing suggest that Web users, overwhelmed by information and quality uncertainty, will gravitate toward the popular choices made by earlier decision makers, which appear via indicators such as hit counts to forge quality impressions. Building on the theories, we hypothesize that how much viewer exposure videos will attract at any future time depends on their viewership accumulated individually; furthermore, this viewership cascade is moderated by pictorial and verbal preview because such information reduces quality uncertainty for content shoppers. Our longitudinal model tests these hypotheses using an extensive real-life dataset on video clips retrieved from a video-sharing site.

Abstract

This comprehensive annotated webliography describes online cataloging resources that are free to use, currently updated, and of high quality. The major aim of this webliography is to provide assistance for catalogers who are new to the profession, unfamiliar with cataloging specific formats, or unable to access costly print and subscription resources. The annotated resources include general websites and webpages, databases, workshop presentations, streaming media, and local documentation. The scope of the webliography is limited to resources reflecting traditional cataloging practices using the Anglo-American Cataloguing Rules, 2nd edition, RDA: Resource Description and Access, and MAchine Readable Cataloging (MARC) standards. Non-MARC metadata schemas like Dublin Core are not covered. Most components of cataloging are represented in this webliography, such as authority control, classification, subject headings, and genre terms. Guidance also is provided for cataloging miscellaneous formats including sound and videorecordings, streaming media, e-books, video games, graphic novels, kits, rare materials, maps, serials, realia, government documents, and music.

Abstract

Words symbolically represent communicative and behavioral intent, and can provide clues to a communicator's future actions in online communication. This paper describes a sociotechnical study conducted from 2008 through 2015 to identify deceptive communicative intent within group context as manifested in language-action cues. Specifically, this study used an online team-based game that simulates real-world deceptive insider scenarios to examine several dimensions of group communication. First, we studied how language-action cues differ between groups with and groups without a compromised actor. We also examine how these cues differ within groups in terms of the group members' individual and collective interactions with the compromised actor. Finally, we look at how the cues of compromised actors differ from those of noncompromised actors, and how communication behavior changes after an actor is presented with an ethical dilemma. The results of the study further our understanding of language-action cues as indicators for unmasking a potential deceptive insider.
