Abstract: Describes the coming together of 2 independent user interface softwares for improving access to databases: MenUSE (Menu-based User Search Engine) and HIBROWSE (High Resolution Interface for Database Specific BROWsing and SEarching). MenUSE was developed for searching bibliographic databases whilst HIBROWSE is a front end for searching information stored on structured relational database management systems. Combining these 2 approaches affords users much greater access capabilities than is possible using traditional information retrieval systems. Describes the power of HIBROWSE in the context of EPOQUE (the European Parliament Online QUEry system) and the INSPEC database

Abstract

The application of classification schemes and thesauri to improve online information retrieval can be traced back to the beginnings of online searching itself, but the true potential for using knowledge structures in the user interface has yet to be realized. View-based searching seeks to exploit the classified arrangements in thesauri and existing classification schemes to improve the performance of such systems. HIBROWSE for EMBASE is a system which demonstrates the power of applying an approach to information retrieval which is strongly related to faceted classification. It does this by employing a point a click user interface with mutually constraining views utilising knowledge structure hierarchies for both query specification and the presentation of results. The relevance of this approach to library OPACs is discussed in the context of the digital library, concluding that out legacy of research in classification and indexing is more relevant than ever in the design of systems to cope with the problems of information access

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

The HIBROWSE design offers improved searching functionality for users of bibliographic databases. The interface provides a multi windowed view of data stored on a relational database management system, using layered attribute value aggregation and classification. The user interrogates the database by invoking automatically formulated SQL queries that filter the contents of each window according to user selected attribute values. The interface is described using 'hand crafted' screens to create realistic examples of HIBROWSE systems for EPOQUE, INSPEC, MEDLINE and EMBASE

Abstract

Demonstrates that a mode of interaction, analogous to the optomechanical principles applied in the Peek-a-Boo system, can be applied in computerized retrieval systems to enhance the quality of human-computer interaction radically and increase effectiveness. The MenUSE (Menu based User Search Engine) software has evolved from constructing explicit Boolean combinations of concepts automatically to using an implicit Boolean searching approach, similar to Peek-a-Boo. Thesauri and classification schemes, together with other searchable values, provide the user with views of a database and a means for the recognition and selection of concepts and other parameters by the end user. The resulting filtering model has been implemented for searching the European Parliament's EPOQUE database and for INSPEC. This second application provides illustrations of the technique for this paper

Abstract

This paper presents a description and initial results of an evaluation of EuroMenUSE for the MAC, a system which offers an alternative mode of access to EPOQUE, the document database of the European Parliament. Subjects with a professional interest in European Parliament business, but with no prior knowledge of information retrieval systems, were able to search EPOQUE using EuroMenUSE for the Mac. These end-users achieved better retrieval results than similar subjects using the current Guided Search mode in use at the Parliament. They also performed better than subjects knowledgeable in information retrieval, but who had less subject knowledge, using the SIMBAD Common Command Language interface, the mode of access used by professional documentalists in the Parliament and other European Union Institutions

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
