Abstract

W.S. Cooper's utility theory was used to evaluate end user and mediated searching of online and CD-ROM databases. The searches were conducted by 510 end users, using MEDLINE. The relevance of the references and the usefulness of the documents retrieved were examnied. The study also assessed the perceived value to end users of the information retrieved. Mediated online searching cost 3 times as much as end user CD-ROM searching, but was only about twice as effective in terms of user satisfaction; user convenience should be a high priority for the information provider and mediated CD-ROM searching may be the best compromise currently available as regards cost effectiveness and successful information retrieval for end users

Abstract

Our catalog should not be called a FRBR catalog perhaps, but instead a "FRBR Inspired catalog." As such our main goal has been "practical findability," we are seeking to support the four identified user tasks of the FRBR model, or to "Search, Identify, Select, and Obtain," rather than to create a FRBR catalog, per se. By encoding as much information as possible in the MODS and MADS records we have created, we believe that useful searching will be supported, that by using unique identifiers for works and authors users will be able to identify that the entity they have located is the desired one, that by encoding expression level information (such as the language of the work, the translator, etc) users will be able to select which expression of a work they are interested in, and that by supplying links to different online manifestations that users will be able to obtain access to a digital copy of a work. This white paper will discuss previous and current efforts by the Perseus Project in creating a FRBRized catalog, including the cataloging workflow, lessons learned during the process and will also seek to place this work in the larger context of research regarding FRBR, cataloging, Library 2.0 and the Semantic Web, and the growing importance of the FRBR model in the face of growing million book digital libraries.

Abstract

The aim of the project was to gain a better understanding of the nature of collaboration in the information searching process, and to consider how information systems design could better address and support collaboration activity. Objectives were: to undertake a small scale study of the nature of collaborative activity in the process of searching for information; examine how the transition to increasingly digital libraries will affect the nature of this collaboration; and to make recommendations for enhancing the beneficial effects of collaborative searching with existing technology and for influencing the development of library systems that actively support social activities

Abstract

Reports results of an investigation, undertaken at Sheffield University, Departmant of Information Studies, UK into the effects of postings information (the display on the screen of the number of references in the retrieved sets) on searching behaviour. Linked online searches were conducted, on the LISA database on CD-ROM, with and without postings information. Performance in terms of the number of relevant references, precision and recall was not significantly different whether postings information was available or not; but searches with postings information took more time and more sets were viewed than in searches without postings. Searchers thought that the lack of postings information had affected 90% of their searches. Proposes that training should place greater emphasis on the value of postings information at different stages of the search and should optimize the searching behaviour of those with different searching styles

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

Describes the results of a project to develop conflation tools for searching databases of Latin text. Reports on the results of a questionnaire sent to 64 users of Latin text retrieval systems. Describes a Latin stemming algorithm that uses a simple longest match with some recoding but differs from most stemmers in its use of 2 separate suffix dictionaries for processing query and database words. Describes a retrieval system in which a user inputs the principal component of their search term, these components are stemmed and the resulting stems matched against the noun based and verb based stem dictionaries. Evaluates the system, describing its limitations, and a more complex system

Abstract

Explores the extent to which techniques of word association can be applied to the development of interfaces for data browsing and searching for which the present methods are either not adequate or completely ineffective. Focuses on the development, application and evaluation of aids for browsing associative semantics displayed textually in interfaces as a network of related terms, or displayed visually as a network of terms and pictures

Abstract

Databases of historical texts are increasingly becoming available for end user searching via online or CD-ROM databases. Many of the words in these databases are spelt differently from today with resultant loss of retrieval. The project evaluated a range of techniques that can suggest historical variants of modern language query words, the work deriving from earlier work on spelling correction

Abstract

Considers teleworking in the UK from the perspective of the library and information community the effects of isolation on teleworkers' access to information. Examines the actual and potential roles of libraries, business support services, electronic networks, associations for teleworkers and unions in the provision of information for teleworkers. Concludes that associations for teleworkers and electronic networks are useful sources of information and new contacts. The potential of public libraries could be realized more fully as librarians become skilled in Internet searching. Libraries will become more attractive to teleworkers if the recommendations of the final report of the Public Library Review are implemented

Abstract

The study of subject access to UK academic library catalogues was based on a questionnaires end out during Summer 1991. 86 out of a possible 110 questionnaires were returned. All universities and polytechniques now have OPACs which are progressing well towards comprehensive bibliographical coverage of their libraries' stocks. The MARC format is now widely used. Subject access strategies are usually based on either Library of Congress Subject Headings or inhouse indexing systems but almost half the OPACs studies have no separate subject searching option based on subject indexing is expensive and future subject indexing strategies are best based on pre-existing controlled vocabularies. Strategies authority control is essential. A limited range of software strategies is recommended including the need to limit search results

Abstract

Reports a study of undergraduate students' use of computer-based information retrieval services in relation to their cognitive and learning styles. Includes a survey of staff at Sheffield University, UK on their use of computer databases and the extend to which undergraduates are made aware of these services. Results show that undergraduate use is low and varies greatly between students of differnt faculties. Student searching behaviour was found to be basic and their performance inadequate. Significant correlation's between cognitive and learning styles and search behaviour were found. Computer-assisted learning (CAL) packages were developed and customised for 3 departments. Guidelines were drawn up based on the project's findings for introducing a computerised information sources programme into the undergraduate curriculum and preparing CAL teaching packages on information skills
