    Evolutionary Subject Tagging in the Humanities; Supporting Discovery and Examination in Digital Cultural Landscapes

    In this paper, the authors attempt to identify problematic issues for subject tagging in the humanities, particularly those associated with information objects in digital formats. In the third major section, the authors identify a number of assumptions that lie behind the current practice of subject classification that we think should be challenged. We move then to propose features of classification systems that could increase their effectiveness. These emerged as recurrent themes in many of the conversations with scholars, consultants, and colleagues. Finally, we suggest next steps that we believe will help scholars and librarians develop better subject classification systems to support research in the humanities.NEH Office of Digital Humanities: Digital Humanities Start-Up Grant (HD-51166-10

    Judging a book by its cover: interface elements that affect reader selection of ebooks

    Digital library research has demonstrated the impact of content presentation on both search and reading behaviours. In this paper, we scrutinise the influence of ebook presentation on user behaviour, focussing on document thumbnails and the first page view. We demonstrate that flaws in presentation increase the volume of short time-span reading, and reduce the likelihood of long-span reading when compared to other documents. This reflects other patterns of information seeking behaviour that demonstrate increased short-term reading when information content is uncertain, and suggests an ineffective use of reader time on less useful content

    Capitalizing on Information Organization and Information Visualization for a New-Generation Catalogue

    Subject searching is difficult with traditional text-based online public access library catalogues (OPACs), and the next-generation discovery layers are keyword searching and result filtering tools that offer little support for subject browsing. Next-generation OPACs ignore the rich network of relations offered by controlled subject vocabulary, which can facilitate subject browsing. A new generation of OPACs could leverage existing information-organization investments and offer online searchers a novel browsing and searching environment. This is a case study of the design and development of a virtual reality subject browsing and information retrieval tool. The functional prototype shows that the Library of Congress subject headings (LCSH) can be shaped into a useful and usable tree structure serving as a visual metaphor that contains a real world collection from the domain of science and engineering. Formative tests show that users can effectively browse the LCSH tree and carve it up based on their keyword search queries. This study uses a complex information-organization structure as a defining characteristic of an OPAC that goes beyond the standard keyword search model, toward the cutting edge of online search tools.published or submitted for publicatio

    The Default Art of Classifying the Occult

    Get PDF
    Even as the world of information moves increasingly away from print, academic librarians and patrons spend significant time in neighborhoods of books organized by Library of Congress Classification. Close attention to specific neighborhoods and historical inquiry into their organization opens windows into past and present constructions of knowledge. This essay examines one such neighborhood – the latter ranges of BF, and particularly its tail end, Occult Sciences. It explores the creation of this neighborhood in a deliberately recursive fashion, and the journey to determine how such content came to be collocated by the Library of Congress leads through other classification systems, bookseller catalogs, and even literature. As food for further thought many comments from the essay manuscript’s anonymous reviewers are appended

    Evolutionary Subject Tagging in the Humanities

    Interdisciplinary research in the humanities requires indexing that represents multiple disciplinary perspectives. Most literature has been indexed using traditional models for subject analysis that are either too broad to be helpful or represent a single disciplinary perspective. We question whether traditional print models of subject analysis serve humanistic researchers' needs in working with digital content. It is beyond the capacity of libraries to re-index this body of literature relying on human indexers. We need to develop scalable tools to both re-index extant bodies of literature and newly created literature. Web-scale searching, computational text analysis, and automated indexing each hold promise for addressing various aspects of the problem, but none seem to fully address the problem. This project will gather a group of scholars with expertise in the humanities, computational analysis of texts, and library and information science, to design an approach to the problem

    INTEGRATION OF AUDIO IN IMAGE PASSWORD PROTECTION SYSTEM

    Get PDF
    Usable security has unique usability challenges because the need for security often means that standard human-computer-interaction approaches cannot be directly applied. An important usability goal for authentication systems is to support users in selecting better passwords. Users often create memorable passwords that are easy for attackers to guess, but strong system-assigned passwords are difficult for users to remember. So researchers of modern days have gone for alternative methods wherein graphical pictures are used as passwords. Graphical passwords essentially use images or representation of images as passwords. Human brain is good in remembering picture than textual character. There are various graphical password schemes or graphical password software in the market. However, very little research has been done to analyze graphical passwords that are still immature. There for, this work merges persuasive cued click points and password guessing resistant protocol. The major goal of this work is to reduce the guessing attacks as well as encouraging users to select more random, and difficult passwords to guess. Well known security threats like brute force attacks and dictionary attacks can be successfully abolished using this method
