Abstract

This article presents a novel user-oriented interface for generalised informetric analysis and demonstrates how informetric calculations can easily and declaratively be specified through advanced data modelling techniques. The interface is declarative and at a high level. Therefore it is easy to use, flexible and extensible. It enables end users to perform basic informetric ad hoc calculations easily and often with much less effort than in contemporary online retrieval systems. It also provides several fruitful generalisations of typical informetric measurements like impact factors. These are based on substituting traditional foci of analysis, for instance journals, by other object types, such as authors, organisations or countries. In the interface, bibliographic data are modelled as complex objects (non-first normal form relations) and terminological and citation networks involving transitive relationships are modelled as binary relations for deductive processing. The interface is flexible, because it makes it easy to switch focus between various object types for informetric calculations, e.g. from authors to institutions. Moreover, it is demonstrated that all informetric data can easily be broken down by criteria that foster advanced analysis, e.g. by years or content-bearing attributes. Such modelling allows flexible data aggregation along many dimensions. These salient features emerge from the query interface's general data restructuring and aggregation capabilities combined with transitive processing capabilities. The features are illustrated by means of sample queries and results in the article.

Abstract

The effect that content and layout of bibliographic displays had on the ability of end-users to process catalog information was tested using a 2 x 2 factorial experimental design. Participants were asked to perform two related tasks during the course of the experiment. In the first task, they were asked to select a set of items that they would examine further for a hypothetical paper they must write, using a simulated online catalog to make their assessments of relevance. In the second task, they were asked to examine 20 bibliographic records, decide whether they would choose to examine these items further on the shelf, and identify the data elements that they used to formulate their relevance decision. One group viewed bibliographic records on an interface similar to current online catalogs, one that used data labels and contained data elements commonly found. A second group viewed these records on an interface in which the labels had been removed, but the data elements were the same as those in the first. The third group viewed these records on a labeled display that included enhanced data elements on the brief record display. The final group viewed these records with the same brief record data elements as the third group, but with the labels removed, using ISBD and AACR2 punctuation standards. For the first task, participants using enhanced brief screen interfaces viewed more brief screens and fewer full screens than their counterparts. Screen durations for the second 10 screens were found to have dropped from those of the first 10 screens. Statistical analyses comparing demographic variables to the screen frequencies uncovered many significant differences. Participants using the enhanced-content interfaces made fewer selections from index and full screens, and more selections from brief screens. For the second task, participants who used enhanced-content interfaces were able to make some sort of relevance judgment more frequently than those who used standard-content interfaces.

Abstract

The authors describe user interface tools based on search histories to support legal information seekers. The design of the tools was informed by the results of a user study (Komlodi, 2002a) that examined the use of human memory, external memory aids, and search histories in legal information seeking and derived interface design recommendations for information storage and retrieval systems. The data collected were analyzed to identify potential task areas where search histories can support information seeking and use. The results show that many information-seeking tasks can take advantage of automatically and manually recorded history information. These findings encouraged the design of user interface tools building on search history information: direct search history displays, history-enabled scratchpad facilities, and organized results collection tools.

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

Visual Interfaces to Digital Libraries exploit the power of human vision and spatial cognition to help individuals mentally organize and electronically access and manage large and complex information spaces. They draw on progress in the field of information visualization and seek to shift the users' mental load from slow reading to faster perceptual processes such as visual pattern recognition.Based on two workshops, the book presents an introductory overview as well as a closing listing of the top ten problems in the area by the volume editors.

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
