Abstract

Presents a brief, critical review of LISA PLaus: the CD-ROM database version of LISA and which includes the database of Current Research in Library and Information Science (CRLIS). The review covers the DOS version only, as it appeared in the Summer 1996 CD-ROM, noting that the Windows version was planned for the future. Points to the way LISA has found its mark, if not its fortune, in LISA Plus and notes its strengths, including: ideal suitability for current awareness in library and information science (LIS); massive and convenient consolidation of the published LIS literature; and massive increase in coverage from 7.900 abstracts in 1993 to over 12.000 currently. Criticizes certain features of LISA Plus, notably: the OPTI-Ware search interface; the combination of 2 databases (LISA and CRLIS) in a single, searchable database; and certain unexpected effects caused by the building of the Subject and Free Text indexes. Points particularly to great lack of consistency in the indexes and the indexing (faults that were fully rectified by a complete overhaul of the data in Summer 1996). Notes that LISA Plus is the first port of call for both information researchers and information science students. The Windows version of LISA Plus was launched in Spring 1997

Abstract

The growth of medical, academic resources on the World Wide Web has led to much greater incentives and opportunities for nursing and medical students, researchers and practitioners to access Web resources. However, usersindividual differences and the variety of information-retrieval mechanisms provided by medical web resources may combine to reduce the benefits of this information resource. In a study designed to qualitatively analyse the interaction of such individual- and system-differences, a reliable method of representing WWW navigational data was found to be important in assisting traditional methodologies of representation and analysis. The methodology of graphically representing such navigational data, and the support such a technique may offer the qualitative analysis of user-system interactions, is thus described in detail and with reference to one specific example drawn from the data collected. Further, some preliminary findings deriving from the use of graphical and more traditional methodologies in this study are also represented

Abstract

Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

Abstract

Standards for user interfaces for access to bibliographic data bases cannot be developed without more complete understanding of the current user, user attitude and capabilities. Gives 3 means of achieving this based on observing the user. 45% of access points in subject searches results in no retrievals. Errors in searching on-line catalogues occur with a 40% no hit title search rate and a 51% no hit author search rate when those records were on the data base. Stresses the importance of fundamental user interface components contained in the IBM staff publication systems guide. Concludes that although there is no such thing as a standard user it is still vital to develop user standards

Abstract

Science mapping is discussed in the general context of information visualization. Attempts to construct maps of science using citation data are reviewed, focusing on the use of co-citation clusters. New work is reported on a dataset of about 36.000 documents using simplified methods for ordination, and nesting maps hierarchically. an overall map of the dataset shows the multidisciplinary breadth of the document sample, and submaps allow drilling down the document level. An effort to visualize these data using advanced virtual reality software is described, and the creation of document pathways through the map is seen as a realization of Bush's associative trails

Abstract

The HIBROWSE design offers improved searching functionality for users of bibliographic databases. The interface provides a multi windowed view of data stored on a relational database management system, using layered attribute value aggregation and classification. The user interrogates the database by invoking automatically formulated SQL queries that filter the contents of each window according to user selected attribute values. The interface is described using 'hand crafted' screens to create realistic examples of HIBROWSE systems for EPOQUE, INSPEC, MEDLINE and EMBASE

Abstract

Modern online information systems have been criticized as being too complicated for the average information seeker. To overcome this problem interfaces have been developed to assist users at all stages of the information transfer process from searching to analysis and evaluation of retrieval data. However, the effectiveness of an interface will depend on the skills of the user. Further development of interfaces will be aided by the use of Windows and mouse controlled systems

Abstract

Describes the development, by the Faculty of Computer Science and Information Technology, Malaya University, of ONLIS (Online Library Information System), a customized user interface for coputerized MARC cataloguing and information retrieval, targeted for use in small libraries and information centres. Micro CDS/ISIS ver. 3.07 software package and its built in PAscal language were used for the design process and development. Design philosophy centres on the development of a very user friendly and simple interface, capable of mimicking the salient features of a contemporary commercial library package, yet easy to implement and maintain in a small library environment requiring little or no technical expertise. The system incorporates many new features and comprises 2 main components: data entry and file maintenace; and information retrieval. A security system is incorporated into the former environment to ensure data integrity and regulate important file maintenance tasks. While the system is ready for immediate implementation in libraries, modifications and enhancements are currently being undertaken to make it a truly reliable product. Concludes that some degree of user training in MARC and cataloguing using AACR2 is necessary to get the maximum benefits from the systems

Abstract

The purpose of this exploratory study is to develop research methods to compare the effectiveness of two video browsing interface designs, or surrogates-one static (storyboard) and one dynamic (slide show)-on two distinct information seeking tasks (gist determination and object recognition). Although video data is multimodal, potentially consisting of images, speech, sound, and text, the surrogates tested depend on image data only and use key frames or stills extracted from source video. A test system was developed to determine the effects of different key frame displays on user performance in specified information seeking tasks. The independent variables were interface display and task type. The dependent variables were task accuracy and subjective satisfaction. Covariates included spatial visual ability and time-to-completion. The study used a repeated block factorial 2x2 design; each of 20 participants interacted with all four interface-task combinations. No statistically significant results for task accuracy were found. Statistically significant differences were found, however, for user satisfaction with the display types: users assessed the static display to be "easier" to use than the dynamic display for both task types, even though there were no performance differences. This methodological approach provides a useful way to learn about the relationship between surrogate types and user tasks during video browsing

Abstract

Hypertext systems provide an appealing mechanism for informally browsing databases by traversing selectable links. However, in many fact finding situations string searching is an effective complement to browsing. Describes the application of the signature file method to achieve rapid and convenient strung search in small personal computer hypertext environments. The method has been implemented to a prototype, as well as in a commercial product. Presents performance data for search times and storage space from a commercial hypertext database and discusses user interface issues. Experience with the string search interface indicates that it was used successfully by novice users

Abstract

Discusses the human-computer interface for information retrieval and notes that research on human-computer interface design has generated many widely-accepted principles of interface design which should be of interest and value to designers of information retrieval systems. Work on display features such as highlighting, colour, icons, and windows has received considerable attention. research has also focused on how the user interacts with the system, whether by commands, menus, or direct manipulation. Studies of interfaces for information retrieval systems reveal that online searching has emphasised developments of front ends, with some novel uses of graphics. CD-ROM and optical media are characterised by interface diversity, again with some inclusion of graphic interfaces. Online catalogues and full text data bases have provided interesting comparisons of mode of interaction
