Virtual Reference for Video Collections: System Infrastructure, User Interface and Pilot User Study

A new video-based Virtual Reference (VR) tool called VideoHelp was designed and developed to support video navigation escorting, a function that enables librarians to co-navigate a digital video with patrons in the web-based environment. A client/server infrastructure was adopted for the VideoHelp system and timestamps were used to achieve the video synchronization between the librarians and patrons. A pilot usability study of using VideoHelp prototype in video seeking was conducted and the preliminary results demonstrated that the system is easy to learn and use, and real-time assistance from virtual librarians in video navigation is desirable on a conditional basis

Using Search Engine Technology to Improve Library Catalogs

This chapter outlines how search engine technology can be used in online public access library catalogs (OPACs) to help improve users’ experiences, to identify users’ intentions, and to indicate how it can be applied in the library context, along with how sophisticated ranking criteria can be applied to the online library catalog. A review of the literature and current OPAC developments form the basis of recommendations on how to improve OPACs. Findings were that the major shortcomings of current OPACs are that they are not sufficiently user-centered and that their results presentations lack sophistication. Further, these shortcomings are not addressed in current 2.0 developments. It is argued that OPAC development should be made search-centered before additional features are applied. While the recommendations on ranking functionality and the use of user intentions are only conceptual and not yet applied to a library catalogue, practitioners will find recommendations for developing better OPACs in this chapter. In short, readers will find a systematic view on how the search engines’ strengths can be applied to improving libraries’ online catalogs

Revisiting the archival finding aid

Archivists have been creating finding aids for generations, and in the last three decades they have done this work via a succession of standardized formats. However, like many other disciplines, they have carried out such work in violation of systems analysis. Although purporting to have the users of finding aids systems first and foremost in their mind, archivists have carried out their descriptive work apart from and with little knowledge of how researchers find and use archival sources. In this article, questions are raised about the utility of archival finding aids and how they will stand the test of time. Indeed, archivists, purportedly concerned with considering how records function and will be used over time, ought to apply the same kind of analysis and thinking to their finding aids. In this article, we explore three ways archival finding aids might be examined by outsiders, namely, those concerned with museum exhibitions, design experts, and accountability advocates. Doing this should assist archivists to reevaluate their next wave of experimentation with descriptive standards and the construction of finding aids. Archivists should expand the notion of what we are representing in archival representation. © 2007 by The Haworth Press

Designing Search: Effective Search Interfaces for Academic Library Websites

Academic libraries customize, support and provide access to myriad information systems, each with complex graphical user interfaces (GUIs). The number of possible information entry points on an academic library Web site is both daunting to the end user and consistently challenging to library Web site designers. Faced with the challenges inherent in designing online search interfaces and the ever-growing amount of resources available online, VCU Libraries sought to explore how to build effective search interfaces that, at the same time, support a wide variety of computer users and provide comprehensive access to assorted collections of electronic resources. Over a 9 month period, the Libraries designed, implemented and tracked the usage of 2 different search interfaces on their homepage. Each interface allowed the user to choose between 4 different search targets. In this case study, the authors discuss the complexities of designing search interfaces, outline findings from the 9 month study, evaluate the effectiveness of the 2 interface designs and about talk about future research in these areas

End-users\u27 perceptions : an exploration on the study of electronic resources

The introduction of technology into the quest for information stimulates a need to educate, instruct, and guide end-users in their ability to effectively manipulate various electronic resources (i e, online public access catalogs (OPAC), CD-ROM databases, and the Internet). A study from the end-user’s perspective was conducted at Emmanuel School of Religion, a graduate seminary, located in Johnson City, Tennessee to illustrate the need for end-user education. Over 80% of the end-users surveyed indicate a greater use of the Internet than to the Online Public Access Catalog (OPAC) and CD-ROM databases (American Theological Library Association (ATLA) and Religious and Theological Abstracts (RTA)). Respondents, in spite of the age of technology, continue to find human interaction, i.e., personal assistance from a librarian or another student to be a useful part of the instruction process. This study also reveals that many of the respondents do not use available help screens even though there is an active use of the electronic resource. = Suggestions to the information professional as to how they can develop programs geared toward end-user instruction are made based on the responses generated from the end-user’s perspective

Ariadne: An interface to support collaborative database browsing:Technical Report CSEG/3/1995

This paper outlines issues in the learning of information searching skills. We report on our observations of the learning of browsing skills and the subsequent iterative development and testing of the Ariadne system – intended to investigate and support the collaborative learning of search skills. A key part of this support is a mechanism for recording an interaction history and providing students with a visualisation of that history that they can reflect and comment upon

User Models for Information Systems: Prospects and Problems

Expert systems attempt to model multiple aspects of human-computer interaction, including the reasoning of the human expert, the knowledge base, and characteristics and goals of the user. This paper focuses on models of the human user that are held by the system and utilized in interaction, with particular attention to information retrieval applications. User models may be classified along several dimensions, including static vs. dynamic, stated vs. inferred, and short-term vs. longterm models. The choice of the type of model will depend on a number of factors, including frequency of use, the relationship between the user and the system, the scope of the system, and the diversity of the user population. User models are most effective for well-defined tasks, domains, and user characteristics and goals. These user-system aspects tend not to be well defined in most information retrieval applications.published or submitted for publicatio

Applying the User-Centered Paradigm to Cataloging Standards in Theory and Practice: Problems and Prospects

Dervin and Nilan’s (1986) article, “Information needs and uses,” has been an influential article in Library and Information Science (LIS), because it calls for a paradigm shift in LIS away from research that focuses on systems and standards to research that focuses on users. This article also has been influential on library and information practice. Librarians and other information workers are called on to be user-centered and place users at the center of library programs and services. Conforming to the user-centered paradigm, however, has been problematic for broad representational systems, like library cataloging, that must meet the diverse needs of global users. Despite calls to focus on users, the cataloging field has not taken a user-centered approach in research or in the development of cataloging standards. Instead, the responsibility to meet users’ needs has been placed on cataloging practitioners, who are encouraged to customize bibliographic records to meet their local users’ needs. Dissertation research by Hoffman (2008) suggests that catalogers are limited in their ability to customize bibliographic records, because catalogers do not know who their users are and cannot identify their users’ needs. In addition, library administrators discourage customization in favor of efficient cataloging processes. There are limits to LIS’s user-centered paradigm in the area of cataloging, and perhaps it needs to examined and reconsidered. Is the user-centered paradigm still applicable to cataloging? How should cataloging meet users’ needs? This paper will examine the problems of the user-centered paradigm in cataloging
