Abstract

Farradane's theory of relational analysis has wide applications in information retrieval. The major areas of application cover their use in retrospective searches, semantic analysis of information, concept organisation and control, efficiency as an information retrieval tool, multilingual indexing tool, in SDI term relations in thesauri, study of nature of subjects, computerised indexing systems, analysis and measuring of information and organisation of current information. Most of the applications were in scientific subjects and the data bases considered were too small to generalise. Suggests 5 new areas of research on relational indexing: compilations of a detailed manual; application in scientific, social sciences, and humanities literature; application in study of the nature of subject literature; comparative efficiency of relational indeximg; and a compilation of a relational thesaurus.

Abstract

Design aspects of bibliographic databases are of utmost importance for effective resource sharing and for providing better information retrieval services in libraries. Standard formats such as the Common Communication Format (CCF) may be adapted for the design of databases. Experience shows that some modifications to the CCF format may be more useful for manipulation of data for various libray operations. Proposes the design of a bibliographic database based on CCF for use in Micr-CDS/ISIS. Almost all the mandatory CCF fields have been adopted and a few new fields added for achieving better results. Formats for display of records conform to AACR2. Provides ample catalogue entries and sample indexes to illustrate how the proposed design helps perform various information retrieval operations in libraries. Modifications in the display of records may be achieved with little effort

Abstract

Reference services have taken a central place in library and information services. They are also regarded as personalised services since in most cases a personal discussion takes place between a user and a reference librarian. Based on this, the librarian points to the sources that are considered to be most appropriate to meet the specific information need(s) of the user. Since the Web and digital libraries are meant for providing direct access to information sources and services without the intervention of human intermediaries, the pertinent question that appears is whether we need reference services in digital libraries, and, if so, how best to offer such services. Current digital libraries focus more on access to, and retrieval of, digital information, and hardly lay emphasis on the service aspects. This may have been caused by the narrower definitions of digital libraries formulated by digital library researchers. This paper looks at the current state of research in personalised information services in digital libraries. It first analyses some representative definitions of digital libraries in order to establish the need for personalised services. It then provides a brief overview of the various online reference and information services currently available on the Web. The paper also briefly reviews digital library research that specifically focuses on the personalisation of digital libraries and the provision of digital reference and information services. Finally, the paper proposes some new areas of research that may be undertaken to improve the provision of personalised information services in digital libraries.
