Abstract

Im Jahr 1995 entstand in interdisziplinärer Zusammenarbeit der Prototyp Bücherschatz, ein Bibliotheks-Online_katalog für Kinder. Beteiligt waren Studierende und eine Professorin der FH Hamburg, Fb Bibliothek und Information, ein Designer und 2 Informatikerinnen der Universität Hamburg. In diesem Bericht werden sowohl das Produkt Bücherschatz als auch der Prozeß seiner Entwicklung beschrieben. Ein Schwerpunkt liegt in der Auseinandersetzung mit theoretischen Modellen der Softwaretechnik - hier STEPS und Prototyping - und ihrer Anpassung an konkrete Projekterfordernisse. Weiterhin werden Fragen nach der Gestaltung kindgerechter Software, der Organisation eines großen Projektteams und nach der Art der Partizipation der Benutzer thematisiert. Das Gesamtprojekt wird in einen wissenschaftlichen Kontext der Informatik eingeordnet, und zentrale Erfahrungen und Erkenntnisse hinsichtlich interdisziplinärer und partizipativer Softwareentwicklung werden zusammengefaßt

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

Describes a feasibility study funded by BLRDD to test a new concept in bibliographic control in OPACs based on the manifestation of the work. The research was conducted at Bradford University, leading directly from the QUALCAT project, and used bibliographic records supplied by OCLC. A new type of hierarchical bibliographic record structure was used to import sets of bibliographic records into a hierarchical relational database. This was used for an experimental Windows based OPAC. Much of the early part of the project was spent clarifying the practical and theoretical implications of the manifestations concept

Abstract

A project to design a graphical user interface for the OKAPI online catalogue search system which uses the basic term weighting probabilistic search engine. Presents a research context of the project with a discussion of interface and functionality issues relating to the design of OPACs. Describes the design methodology and evaluation methodology. Presents the preliminary results of the field trial evaluation. Considers problems encountered in the field trial and discusses contributory factors to the effectiveness of interactive query expansion. Highlights the tension between usability and functionality in highly interactive retrieval and suggests further areas of research

Abstract

Describes work of the BOPAC2 project, funded by the British Library Research and Inoovation Centre, from Sep 1996 to Jan 1997, to investigate the issues involved in managing large and complex retrievals involving Z39.50 searches, including searches of multiple databases. The system is a WWW front end that allows simultaneously access to a number of library OPACs via Z39.50. The system is designed to make access to large and complex retrieval simpler, similar records are clustered together and retrievals may be sorted in a number of ways and by different criteria. Describes the design, development and evaluation of the system with suggestions for future work

Abstract

The ENQUIRE project forms part of a series of investigations on query expansion in the Okapi experimental text retrieval system. A configurable user interface was implemented as an evaluative tool and tested in two locations on two different databases: the library catalogue of The London Business SChool and the computing section of INSPEC. The system offered a range of possible strategies based on thesaural terms for reformulating queries. These could be initiated automatically by the system or interactively with the user. The formative phase of the evaluation established the appropriateness and usability of the interface as well as users' perceptions of the underlying functionality. The aim of the large scale field trial was to determine to what extent user would select thesaural terms suggested by the system to reformulate queries, and to evaluate the effectiveness of a new dynamic form of query expansion implemented for this project
