- Abstract
- Compares and contrasts online searching on DataStar using the 'classic' command language, with access via the more recent Web interface (DataStar Web). The search functionality of the 2 interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike

- Abstract
- The physical organisation of items on library shelves using any classification scheme is inevitable a compromise. The best efforts to achieve an arrangement that is helpful to users will be thwarted by the multifaceted nature of these items and the specific needs of the user and the library. Items on a particular subject will be scattered throughout the library building(s) across disciplines, by physical form, by frequency of use and whether and for how long they may be borrowed. Even thought he rich information content of multifaceted items may be represented in the notation, the items required by a user will be scattered across library shelves when the item is placed in a single relative location. This paper explores these issues uisng examples from a University Library classified using the DDC. The electronic context of the library OPAC can transcend the constraints imposed by the predominantly physical nature of library collections, yet the current use of classification schemes in on-line systems retains many of these limitations. Examples of such systems applying DDC on the WWW are discussed and compared with a system that seeks to use DDC in what is called view-based searching. The interface and the resulting browsing and searching capability of a view-based OPAC are described. Ways in which subject access to library collections can be improved and disciplinary scatter resolved by assigning multiple class number to items and exploiting the rich Dewey structure in a faceted form are discussed. It is suggested that the informative power of visual classificatory structures at the search interface will be beneficial to the broader learning experience of the user. The paper concludes that the application of classification schemes in electronic interfaces should not be bound by the the physical constraints that no longer apply in an electronic context but be exploited to provide a complete, flexible and individual interface as determined by the needs of each user

- Abstract
- Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system

- Abstract
- In the short term, technological advances will not solve the problems of information saturation and electronic gridlock on the Internet. Advocates interface design techniques as the only effective means of addressing the usability problems that frustrate interaction with Internet resources. Collaborative approaches to information retrieval, where search engines are augmented by advice from human experts, can reduce the problems of electronic gridlock and information saturation

- Abstract
- Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

- Abstract
- Focuses on the user and human-computer interaction (HCI) aspects of the research based on the Okapi text retrieval system. Describes 3 experiments using different approaches to query expansion, highlighting the relationship between the functionality of a system and different interface designs. These experiments involve both automatic and interactive query expansion, and both character based and GUI (graphical user interface) environments. The effectiveness of the search interaction for query expansion depends on resolving opposing interface and functional aspects, e.g. automatic vs. interactive query expansion, explicit vs. implicit use of a thesaurus, and document vs. query space

- Abstract
- The design and development of the Open Agent Architecture (OAA) system has focused on providing access to agent-based applications, through an intelligent, cooperative, distributed, and multimodal agent-based interface. Only the primary user interface agents need run on the local computer, thereby simplifying the task of using a range of applications from a variety of platforms, especially low-powered computers. An important consideration in the design of the OAA was to facilitate the reuse of agents in new and unanticipated applications and to support rapid prototyping. The utility of the agents and tools developed has been demonstrated by their use as infrastructure in unrelated projects

- Abstract
- Information retrieval systems such as library OPACs have been largely designed to give the impression of being single user systems, the existence and activity of other users being hidden from each other. However, informal observations indicate significant collaboration between users despite the fact that existing systems fail to support this. Describes the development of an interface, the Ariadne system, that supports collaboration through the storage and re-use of others' search processes promoting better visualization of the information data structures being browsed and more effective means of communicating the browsing process. Discusses issues relating to privacy and ownership resulting from the storage of users' searches. Argues that introducing support for collaboration into information retrieval systems would help users to learn and use the systems more effectively

- Abstract
- Information retrieval and exploration of work domains through databases and integrated information systems has become increasingly important in many modern work settings (as well as in libraries). The problem space of the users is defined on occasion by the dynamically changing requirements from their tasks and goals. it is argued that IR system design should be based on an analysis of the properties of the work domain, the task situation and the user characteristics. The paper describes a general framework for IR system design that has been used in the design of a library system. A special problem identified from use of the framework in domain analysis of fiction retrieval is treated in more detail: mapping the authors' domain structures to the domain structures expressed in users' needs in indexing and representation of fiction

- 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
- Develops a framework for assessing the appropriateness of alternative interfaces and user tasks for systems in which significance of computational delays cannot be ignored. The framework is motivated by the ability of users to attune to the duration and pace of events in their environment. The framework is applied to interactive information retrieval, assessing alternative design, and identifying how interface design details can enhance effective interactive information retrieval. Temporal interface requirements can have a significant influence upon overall system design and the view of task adopted by users

- Abstract
- Reports on work in progress to define an object oriented model of a probabilistic information retrieval system (OKAPI), the central component of which is the query itself. Considers how to represent queries both internally and at the user interface level, and their relationship with other components of the model. The model will form the basis of a configurable user interface, which allows controlled experiments to be undertaken, and could be adapted to the needs of different users accessing different databases. Implementation will involve the use of a high level interpreted scripting language for overall control, communicating with an internal model and an interface model, designed and developed using object oriented techniques

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
- This paper examines issues relating to the use of the Dewey Decimal Classification (DDC) in a future development of view-based searching to Online Public Access Catalogues (OPAC). View-based searching systems, exercising the principles of fully faceted classification techniques for both bibliographic and corporate database retrieval applications, are now being applied to utilise Dewey concept hierarchies in a University OPAC. Issues of efficiency and effectiveness in the evolving organisation and classification of information within libraries are examined to explain why fully faceted classification schemes have yet to realise their full potential in libraries. The key to their application in OPACs lies in the use of faceted classification as pre-coordinated indexing and abandoning the single dimension relative ordering of books on shelves. The need to maintain a single relative physical position on a bookshelf is the major source of complexity in classification. Extensive latent benefits will be realised when systematic subject arrangements, providing alternative views onto OPACs, are coupled to view-based browser and search techniques. Time and effort will be saved, and effectiveness increased, as rapid access is provided to the most appropriate information to satisfy the needs of the user. A future for Dewey Classification divorced from its decimal notation is anticipated

- Abstract
- Reports the findings of a study, conducted by Temple, Barker and Sloane Inc., MA, which identified 7 measurable benefits of graphic user interfaces to computerized information retrieval systems; higher speed; more accurate work; higher productivity; less frustration; less fatigue, more facilities to self teach and explore system; greater facilities for novices to learn more about the system's capabilities. Concludes that, when compared with character based user interfaces, graphic user interfaces generate higher work outputs per work hour through higher productivity; higher work output per employee through lower levels of frustration and fatigue; and greater returns on information technology investment through reduced demand for user training
