Abstract

In the present environment of database searching, the research library user who is familiar with the concept of keyword searching with Boolean logic capabilities very often uses this same strategy in the online catalog rather than looking up the established form of the heading listed in 'Library of Congress Subject Headings' and 'Library of Congress Name Authorities'. Questions that needed to be addressed were: does keyword searching provide a satisfactory substitute for searching by the authorized heading, and what kind of service or disservice do libraries to their users when keyword searching is the only strategy tried? This study determined how many of of the nonauthorized headings listed as cross references in an authority system could be found in the bibliographic record. It also examined the necessity for truncation of the keyword terms derived from the nonauthorized heading. A weighted system measured the frequency with which individual MARC fields provided matches for the keywords. The results of this study lead to recommendations for maximizing search strategies

Abstract

Recognition, by libraries, of the need for improved efficiency and reliability in subject authority control in catalogues led to a study of the feasibility of automatically creating a subject heading validation file by scanning the OLUC. The premises were: that although the file would not be axhaustive, it would contain the majority of frequently used headings; and that the predicted level of accurary in the file would be high. A sample file of Library of Congress assigned subject headings, from the OCLC Subject Headings Corrections database was analyzed. Results showed that: the frequency of use varies inversely with the number of headings at a given rrate of use; a small number of headings with high frequencies of use accounts for the majority of total use, while a large proportion shows very low frequency of use; topical headings account for 2/3 of assigned headings; and error and obsolescence rates are both low and are in inverse relationship to the frequency of heading use. Concludes that an automatically generated subject heading validation file is feasible and could serve various purposes, including: verification of subject heading strings constructed by cataloguers; updating of subject headings in catalogue maintenance; and validation of subject headings during retrospective catalogue conversion

Abstract

Authority records complement bibliographic records, providing cataloguers with essential subject heading and related information. At present there is no international format standard comparable to ISBD for bibliographic records, though IFLA and the International Archives Council have set up working groups. The essential data form comprises of subject heading, structure, homonyms, with supplementary supporting information. In France MARC formats are most widely used, e.g. UNIMARC(A) for authority records and (B) for bibliographic. The National Library (BNF) is introducing new cataloguing software based on the reorganisation of its authotity files, using integrated INTERMARC. As an experiments, readers will for the first time have access to authority files, thus enriching, completing and clarifying the bibliographic records

Abstract

The 'Guida all'indicizzazione per soggetto', the outcome of the work of the GRIS collaborative project of Italian research and academic libraries on subject heading schemes for Italian libraries, was published in 1996, though not in a definitive form. Presents some notes as a contribution to the definitive version, particularly section 3. The latter is concerned with the control of terms, including the analysis of categories, the morphology of terms and the structure of vocabulary

Abstract

Discusses the problems in establishing commonly accepted principles for subject retrieval between different bibliographic systems. The Working Group on Principles Underlying Subject Heading Languages was established to devise general principles for any subject retrieval system and to review existing real systems in the light of such principles and compare them in order to evaluate the extent of their coverage and their application in current practices. Provides a background and history of the Working Group. Discusses the principles underlying subject headings and their purposes and the state of the work and major findings

Abstract

Discusses the development of Campus Wide Information Systems with reference to the work of Leuven University Library. A 4th phase can now be distinguished in the evolution of CWISs as they evolve towards Intranets. WWW technology is applied to organise a consistent interface to different types of information, databases and services within an institution. WWW servers now exist via which queries and query results are translated from the Web environment to the specific database query language and vice versa. The integration of Java will enable programs to be executed from within the Web environment. Describes each phase of CWIS development at KU Leuven

Abstract

Describes 2 research projects aimed at studying the parallel issues of image and video indexing, information retrieval and manipulation: VisualSEEK, a content based image query system and a Java based WWW application supporting localised colour and spatial similarity retrieval; and CVEPS (Compressed Video Editing and Parsing System) which supports video manipulation with indexing support of individual frames from VisualSEEK and a hierarchical new video browsing and indexing system. In both media forms, these systems address the problem of heterogeneous unconstrained collections

Abstract

Discusses various structural searching methods available on the Web. some databases such as the Brookhaven Protein Database use keyword searching which does not provide the desired substructure search capabilities. Others like CS ChemFinder and MDL's Chemscape use graphical plug in programs. Although plug in programs provide more capabilities, users first have to obtain a copy of the programs. Due to this limitation, Tripo's WebSketch and ACD Interactive Lab adopt a different approach. Using JAVA applets, users create and display a structure query of the molecule on the web page without using other software. The new technique is likely to extend itself to other electronic publications
