- Abstract
- Purpose: To develop a prototype middleware framework between different terminology resources in order to provide a subject cross-browsing service for library portal systems. Design/methodology/approach: Nine terminology experts were interviewed to collect appropriate knowledge to support the development of a theoretical framework for the research. Based on this, a simplified software-based prototype system was constructed incorporating the knowledge acquired. The prototype involved mappings between the computer science schedule of the Dewey Decimal Classification (which acted as a spine) and two controlled vocabularies UKAT and ACM Computing Classification. Subsequently, six further experts in the field were invited to evaluate the prototype system and provide feedback to improve the framework. Findings: The major findings showed that given the large variety of terminology resources distributed on the web, the proposed middleware service is essential to integrate technically and semantically the different terminology resources in order to facilitate subject cross-browsing. A set of recommendations are also made outlining the important approaches and features that support such a cross browsing middleware service.

- Abstract
- Reports results of a study which applied a typological procedure, developed by Lazairsfeld from the social sciences, to a set of qualitative data on fiction reading habits for the purpose of forming a practical typology of fiction borrowers. The data was collected from a sample of 300 readers in 2 medium sized UK public libraries over a 2 month period. The procedure, using an inductive research approach, first mapped readers along 6 dimensions of reading habits which emerged from the data frequencies of borrowing, the numbers of authors currently read, the literary/recreational orientation of reading, searching approaches usually applied, sureness (confidence) in book selection and then proceeded to reduce the number of combinations formed by these dimensions, based on their relationships. A typology of 7 types of fiction borrowers was devised: readers of particularism; readers of frequent literary pluralism; readers of infrequent literary pluralism; readers of frequent recreational pluralism; readers of infrequent recreational pluralism; readers of frequent universalism; and readers of infrequent universalism

Subsequently, six further experts in the field were invited to evaluate the prototype system and provide feedback to improve the framework. Findings - The major findings showed that, given the large variety of terminology resources distributed throughout the web, the proposed middleware service is essential to integrate technically and semantically the different terminology resources in order to facilitate subject cross-browsing. A set of recommendations are also made, outlining the important approaches and features that support such a cross-browsing middleware service. Originality/value - Cross-browsing features are lacking in current library portal meta-search systems. Users are therefore deprived of this valuable retrieval provision. This research investigated the case for such a system and developed a prototype to fill this gap.

- Abstract
- The relevance of retrieved documents or document descriptions has been a central measurement in the evaluation of information retrieval (IR) systems. Online public access catalogues (OPACs) are similar in many ways and so relevance should be an appropriate evaluation tool in measuring their performance. The development of relevance in evaluating IR systems is described and also the important differences between such systems and OPACs. Characteristics of the end-users of both systems are discussed with the conclusion that end-users' motivation and behaviour are as yet not fully understood. The implcations of this is that relevance is a central feature, but only one, of an OPAC user's overall information need

- Abstract
- Shortened and revised version of a paper presented during an Education Librarian's Group session at the Under One Umbrella Two Conference, organized by the Library Association in Manchester, 9-11 Jul 93. With the possibility of free text searching and easy access to CD-ROM databases, users often do not realise that subject searching is enhanced by familiarity with the controlled vocabulary underlying the indexing system of the database. Discusses the construction of information retrieval thesauri, the problems of terminology and how the use of thesauri can make searching more effective, using education thesauri as examples

- 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
- Research conducted in the early 80's has shown that subject access is still one of the most dominant approaches in OPACs. However, while some of the subject searches result in no recall, others often retrieve so much that users are discouraged to proceed further. These and other problems were investigated and solutions were found in improving search methods (such as word stemming, extending search to full bibliographical record and providing end user thesaurus) and indexing techniques (such as ny enhancing subject headings with table of contents and back of the book indexes or by traditional systems). More recent research indicates that the real answer to the question of 'precision without sacrificing recall' lies in the developing 'user friendly novel interfaces' and also in designing 'knowledge based systems', wherein sers would not be expected to learn query formulation or even to be familiar with the indexing language of the system. Several interesting studies and research projects on the subject have produced a whole gamut of information, but one can still visualise the evolving trends of research vis-a-vis their future prospects as possible solutions
