- Abstract
- A new search paradigm, in which the primary user activity is the guided exploration of a complex information space rather than the retrieval of items based on precise specifications, is proposed. The author claims that this paradigm is the norm in most practical applications, and that solutions based on traditional search methods are not effective in this context. He then presents a solution based on dynamic taxonomies, a knowledge management model that effectively guides users to reach their goal while giving them total freedom in exploring the information base. Applications, benefits, and current research are discussed.

- Abstract
- View based searching and multi view searching using HIBROWSE proposes a new paradigm for information retrieval from bibliographic databases and database management systems. The paradigm replaces command line and form based interaction with query specification and interaction which requires the user to identify views relating to query facets of the subject of their query. Attempted to apply techniques from human-computer interaction design in the development, construction and usability evaluation of a view based searching system for a very large bibliographic database. As the development of the HIBROWSE system had been in progress before usability became a major concern, as well as the class of system being developed, greater progress towards improved usability was made by adopting a less structured development life-cycle. Examined the usefulness of a number of usability evaluation methods in the context of trying to determine the usability of designs in interactive information retrieval systems. Measurement of the subjective usability of prototypes reinforced the finding of users' difficulties in forming a useful account of the system behaviour and functionality from the training material provided, highlighted some aspects of the system that could be improved, and the greater usability of the HIBROWSE prototypes over an extant commercial bibliographic database system

- 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

- Abstract
- CD-ROM data bases are being adopted rapidly by libraries and are being made available to end-users. Compares online information retrieval systems and CD-ROM based retrieval systems, assessing structure and content characteristics that contribute to user behaviour. CD-ROM systems are comparable in database content and in interface style, although CD-ROM systems often provide multiple user interfaces, have smaller databases, less time pressure, and no telecommunications requirements. Some of the differences might lead to better retrieval performance by novice users, but many unanswered questions remain about the influence of time pressure, database size, interface style, training, and skill transfer among systems

- Abstract
- We describe a prototype Information Retrieval system; SENTINEL, under development at Harris Corporation's Information Systems Division. SENTINEL is a fusion of multiple information retrieval technologies, integrating n-grams, a vector space model, and a neural network training rule. One of the primary advantages of SENTINEL is its 3-dimensional visualization capability that is based fully upon the mathematical representation of information with SENTINEL. The 3-dimensional visualization capability provides users with an intuitive understanding, with relevance/query refinement techniques athat can be better utilized, resulting in higher retrieval precision

- Abstract
- An evidence-based practice approach to search interface design is proposed, with the goal of designing interfaces that adequately support search strategy formulation and reformulation. Relevant findings from studies of information professionals' searching behaviors, end users' searching of bibliographic databases, and search behaviors on the Web are highlighted. Three brief examples are presented to illustrate the ways in which findings from such studies can be used to make decisions about the design of search interfaces. If academic research can be effectively connected with design practice, we can discover which design practices truly are best practices and incorporate them into future search interfaces.

- Abstract
- The search tools familiar from the personal computer are propagating to mobile devices. Are users willing to type keywords with the limited keypad of an ordinary mobile phone? How does mobile search differ from stationary search? The author found that users are surprisingly willing to use search also with the traditional phone keypad, and foresees a search revolution as mobile devices enable location-based search.

- 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
- The Internet is a medium for education, entertainment, communication, and personal expression. User behavior has developed three main modalities for using this medium effectively - searching, browsing, and monitoring - which are supported to different degrees by conventional tools. Understanding the nature of the interaction allows us to design and implement a system called Mitsukeru to support browsing behaviors, while retaining the free-form movements between other interaction styles. The system uses agent-based modeling and look-ahead to provide informative yet nonintrusive guidance to the user, and is described in detail.

- 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
- This article presents one part of a wider study, performed at the Department of library and information science and book studies (LIS & BS) at the University of Ljubljana (UL). The study investigated the perceptions of user friendliness of information-retrieval systems (IRS) and the role of individual characteristics of users in these perceptions. Based on an expert study, a user study with 61 postgraduate students of the UL was performed. Three interfaces of e-journals were studied: Science Direct, Proquest Direct, and Ebsco Host. Questionnaires and observations were used for data collection. The users'perceptions of user friendliness and of importance of auxiliary functions were investigated. Also, the connections between these perceptions and the users'individual characteristics were identified. Three sets of individual characteristics were included: approaches to studying, thinking styles, and hemisphere leanings. In connection with the dimensions of individual characteristics, very different perceptions of user friendliness were expressed. Some dimensions of individual characteristics were also found to be connected to the users'academic areas. It is shown that participants from different academic areas have different requirements and perceptions of user friendliness. The results of the study are relevant for the design of the user interfaces of disciplinary IR systems. They also have implications for other areas, for example, user education and training.

- Abstract
- With the many choices that can be built into information systems, it is possible to customize such systems for users, based on the tasks that users are accomplishing, on the personal characteristics of users, or a combination of these factors. Reports results of an experiment which detailed logging of use of experimental information systems and was used to determine the optimal configuration of these systems for each user. 4 experimental systems were specially designed and all used a single database of 668 bibliographic records. Tasks were varied, and the cognitive abilities of users were tested to assess one important personal characteristic. Results showed that it was possible to create an optimal configuration to match the cognitive abilities of users, but that it was more difficult to assess which configuration was the best match for specific tasks. The person in task interaction proved to be the least powerful indicator of design configurations. These results suggest that usable information systems can be created for users by careful analysis of the interaction of design features with personal characteristics such as cognitive abilities

- 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.
