- Abstract
- Presents the preliminary results of a pilot research project on disorientation in hypertextual educational systems. It explores spatial cognition's correlation with hypermedia navigation. Analyzes mental models, in order to justify their use as a basis for interface design. Introduces the notion of disorientation in a hypermedia environment. Illustrates the co-ordinates of experiments set up to verify the assumption that users need to build some form of conceptual representation of devices they are interacting with in order to understand them, and reports the results. Redefines the notions of spatial metaphor and of maps in the light of the results

- Abstract
- Reports and combines the results of 2 assessments of full bibliographic displays in the online catalogue of academic libraries. The first assessment evaluated displays in 12 OPACs while the second evaluated displays in 10 WWW based catalogues. Displays were evaluated against a checklist of desirable features derived from published display guidelines. Results showed that, on average, displays in OPACs scored 58% and displays in Web catalogues scored 60%. Discusses some of the weaknesses identified by the assessments, focusing on those found in the majority of the displays evaluated

- Abstract
- Reports text information retrieval experiments performed as part of the 3 rd round of Text Retrieval Conferences (TREC) using the Okapi online catalogue system at City University, UK. The emphasis in TREC-3 was: further refinement of term weighting functions; an investigation of run time passage determination and searching; expansion of ad hoc queries by terms extracted from the top documents retrieved by a trial search; new methods for choosing query expansion terms after relevance feedback, now split into methods of ranking terms prior to selection and subsequent selection procedures; and the development of a user interface procedure within the new TREC interactive search framework

- Abstract
- An approach to accessing databases, which makes extensive use of structured thesaurus views for presenting and searching a large bibliographic database through progressive refinement, is being investigated in a research project which is seeking to apply usability criteria as the determinant for interface design. It aims to investigate measurements of retrieval performance in an application of graphical user interface techniques using multi-windowed layered attribute value aggregation, including those provided by a structured thesaurus, to access bibliographic databases. This paper reports on the progress made in the first year of the project of the application of usability methodologies, the revision of a preliminray design and the resulting prototype development. Implications for more widespread applications are discussed

- Abstract
- Reports the results of a research project, conducted by the School of Computing and Mathematics and the Library of Huddersfield Polytechnic, into the problem of matching the user interface of OPACs to the needs of users. The project brought together issues involving: Human Computer Instruction (HCI); system methods in the determinination of user requirements; and user centred design, and prototyping in a sequence of design and evaluation cycles. These cycles applied appropriate HCI styles, techniques and equipment (such as Graphical User Interface (GUI) and a mouse pointing device) and incorporated the lessons of each evaluation, to produce an OPAC user interface, ICARUS, which differs considerably in style, behaviour and characteristcs from those commonly encountered in academic and public libraries. The project concluded by evaluating ICARUS, against the BLCMP OPAC with 38 subjects in the Library of Huddersfield Polytechnic, and demonstrating a significant improvement in performance for different tasks for the ICARUS interface

- Abstract
- Reports results of a study to compare 3 CD-ROM interfaces working on MEDLINE databases: SPIRS (ver. 3.11) and WinSPIRS (ver. 1.0) from SilverPlatter and OVID (ver. 3.0, DOS and WINDOWS interfaces) from CD Plus Technologies (now OVID Technologies). Though the database is the same, there are substantial differences between the interfaces in the way the data is presented and can be searched. Discusses these different approaches and includes a detailed comparative table. Concludes that all 3 interfaces are good yet none of them is perfect; each has desirable and unfortunate features. Together, they offer an enormous range of possibilities. Users would benefit if most of the better features listed (such as easy menu, free text retrieval, pre exploded thesaurus terms) were implemented in future versions of these interfaces and if system operators were given greater latitude to determine the system defaults appropriate to their specific situations and customers. A full, comparative table of features are presented for SPIRS, WinSPIRS, OVID(DOS) and OVID(Windows)

- Abstract
- Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues

- Abstract
- Geographic maps are a well-established way of representing domain-specific knowledge in a way which integrates symbolic and pictorial representation. This paper proposes an interdisciplinary approach to the understanding of how maps represent and organise knowledge, combining artificial intelligence knowledge representation theory with empirical findings and methods from cognitive psychology. Schematic maps represent knowledge in a different way than topographic or city maps; in particular, distances and directions cannot be evaluated in the same way as in topographic or city maps. However, information from different types of maps must often be combined to answer everyday questions. An inference task involving such a combination, in order to locate a train station shown in a schematic map with respect to a part of a city map, was analysed theoretically with respect to how location judgments change with assumptions about what spatial information is contained in the schematic map. The same task was investigated empirically in a study in which subjects were asked to locate a train station and to describe their thinking in a subsequent verbal report. Results indicate that subjects' judgements and verbal reports can be grouped according to the theoretical analysis
