Abstract

As mentioned above, the guidelines are intended to apply to all types of catalogue, including Web-based catalogues, GUI-based interfaces, and Z39.50-web interfaces. The focus of the guidelines is on the display of cataloguing information (as opposed to circulation, serials check-in, fund accounting, acquisitions, or bindery information). However, some general statements are made concerning the value of displaying to users information that is drawn from these other types of records. The guidelines do not attempt to cover HELP screens, searching methods, or command names and functions. Thus, the guidelines do not directly address the difference between menu-mode access (so common now in GUI and Web interfaces) vs. command-mode access (often completely unavailable in GUI and Web interfaces). However, note that in menu-mode access, the user often has to go through many more screens to attain results than in command-mode access, and each of these screens constitutes a display. The intent is to recommend a standard set of display defaults, defined as features that should be provided for users who have not selected other options, including users who want to begin searching right away without much instruction. It is not the intent to restrict the creativity of system designers who want to build in further options to offer to advanced users (beyond the defaults), advanced users being those people who are willing to put some time into learning how to use the system in more sophisticated and complex ways. The Task Force is aware of the fact that many existing systems are not capable of following all of the recommendations in this document. We hope that existing systems will attempt to work toward the implementation of the guidelines as they develop new versions of their software in the future.

Abstract

In an effort to assist users in the identification of significant Internet resources, libraries and librarians have begun to apply established library classification and subject schemes as the organizational framework for accessing and navigating these electronic sources. We will profile selected notable applications of national and international library classification schemes for organizing World Wide Web (WWW) resources as well as sites that have applied controlled vocabularies to facilitate access to selected collections of Net resources. With these and similar efforts as a conceptual foundation, we then focus on the potential application of new and emerging technologies to further enhance use of digital collections, notably intelligent software agents, information visualization techniques, auditory displays and haptic interactive devices. We conclude with a review of significant Natural Language Processing (NLP) technologies and computer-based ontologies, and speculate on their potential application for representing, accessing, and navigating digital resources

Abstract

When faced with an interface to an unknown system or device humans adopt exploratory interactive behaviour in order to gain information and insight. This paper describes a computer program which probes, observes and models the input-output space of unknown systems. We use a schema concept as the memory structure for recording events and adopt a constructive approach that avoids preprocessing the raw data. We believe qualitative assessments are important in early analysis and employ techniques from qualitative reasoning research in order to capture correlation behaviour. The aim is to gain insight into the nature of an unknown system for guidance in future model selection. A series of experiments and their results are discussed, together with the assumptions and limitations of the method. We suggest further developments for future experiments that appear promising.

Abstract

There is a huge amount of information and data stored in publicly available online databases that consist of large text files accessed by Boolean search techniques. It is widely held that less use is made of theses databases than could or should be the case, and that one reason for this is that potential users find it difficult to identify which databases to search, to use the various command languages of the hosts and to construct the Boolean search statements required. This reasoning has stimulated a considerable amount of exploration and development work on the construction of search interfaces, to aid the inexperienced user to gain effective access to these databases. The aim of our paper is to review aspects of the design of such interfaces; to indicate the requirements that must be met if maximum aid is to be offered to the inexperienced searcher; to spell out the knowledge that must be incorporated in an interface if such aid is to be given; to describe some of the solutions that have been implemented in experimental and operational interfaces; and to discuss some of the problems encountered. The paper closes with an extensive bibliography of references relevant to online search aids, going well beyond the items explicitly mentioned in the text. An index to software appears after the bibliography at the end of the paper

Abstract

This paper outlines strategies and methods for tackling the enormous challenges presented by an emerging Information Society in which the resources of libraries and museums are gradually being made available on-line in electronic form. It begins from two fundamental premises: first, that the experience of libraries, museums, archives and similar institutions in organising, ordering, classing and accessing knowledge is an obvious point of departure for serious strategies of search and access. A second premise is that the methods used for presentation of knowledge in libraries offer valuable clues for a coherent access, interface and strategy, offering a key to a common look and feel for all our activities, be it creating, classing, publishing or accessing. Following from these premises is a new approach to the traditions of knowledge collection, organisation and retrieval. At one end of the spectrum there has been a dream that everything could be collected in one centralized institution. This inspired the Library of Alexandria, the British Museum and a host of other efforts. At the other end of the spectrum there has been an assumption that everything could be decentralised in a completely distributed system. Our claim is that neither of these extremes can work, which means that a new model is called for: a centralised repository of meta-data, a digital reference room which is effectively a cumulative collection of all existing reference sections in libraries and museums

Abstract

Purpose - The purpose of this paper is to determine whether a faceted OPAC interface offers improvements to information discovery in scholarly research. Design/methodology/approach - The 5.2 million records of an entire library catalog were loaded into a faceted navigation interface and an attractive search term suggestion tool. Humanities PhD students at the dissertation level and familiar with this collection were observed while using this interface to continue their research into the literature on their dissertation topic. Findings - From a group of 12 subjects, nine reported finding materials that they had not found in their previous use of the traditional catalog interface. Research limitations/implications - No attempt is made to isolate the effects of relevance ranking on discovery from those of faceted navigation or the search term suggestions. The differences between the circumstances of scholars who did and did not find previously undiscovered materials are not examined. Practical implications - Faceted interface and search term suggestion in a library catalog may enable those scholars who are highly dependent on library materials to find materials that would remain hidden in a traditional library catalog. Originality/value - This article considers whether faceted navigation increases the range of relevant materials that scholars discover, and is of interest to libraries which are considering adding faceted navigation and other features to their catalog interface.
