Abstract

Since it is obviously impossible to "hold" live performances in library collections (in contrast to recorded performances and motion pictures), such creations are barely accounted for in library catalogues and cataloging prescriptions, even as a topic in subject headings. The way AACR and the Anglo-American cataloging tradition deals with performing arts is discussed at length. Conversely, specialized institutions have developed their own rules for the description of live performances: the Dance Heritage Coalition (New York) creates authority records for choreographic works, and the Département des Arts du Spectacle at Bibliothèque nationale de France creates bibliographic records for theatrical, operatic, and choreographic performances. As a conclusion, a tentative modeling of performing arts as bibliographic entities, strictly based on FRBR, is proposed.

Abstract

Undergraduates were tested to establish how they searched databases, the effectiveness of their searches and their satisfaction with them. The students' cognitive and learning styles were determined by the Lancaster Approaches to Studying Inventory and Riding's Cognitive Styles Analysis tests. There were significant differences in the searching behaviour and the effectiveness of the searches carried out by students with different learning and cognitive styles. Computer-assisted learning (CAL) packages were developed for three departments. The effectiveness of the packages were evaluated. Significant differences were found in the ways students with different learning styles used the packages. Based on the experience gained, guidelines for the teaching of information skills and the production and use of packages were prepared. About 2/3 of the searches had serious weaknesses, indicating a need for effective training. It appears that choice of searching strategies, search effectiveness and use of CAL packages are all affected by the cognitive and learning styles of the searcher. Therefore, students should be made aware of their own styles and, if appropriate, how to adopt more effective strategies

Abstract

In 2004, the ALCTS (Association for Library Collections & Technical Services) Cataloging and Classification Section Subject Analysis Committee (SAC) produced the report Recommendations for Providing Access to, Display of, Navigation within and among, and Modifications of Existing Practice Regarding Subject Reference Structures in Automated Systems. This document is one important outcome of nearly ten years' work by three SAC (Subject Analysis Committee) subcommittees investigating the theoretical, pragmatic, and political dimensions of improving subject access through better use of reference structure data. The work of those subcommittees is reviewed and their recommendations are described and summarized. Potential future effects of the report are discussed, as is a snapshot view of several major automation systems' current compliance with the recommendations.

Abstract

The research reported here was an exploratory study that sought to discover the effects of human individual differences an Web search strategy. These differences consisted of (a) study approaches, (b) cognitive and demographic features, and (c) perceptions of and preferred approaches to Web-based information seeking. Sixtyeight master's students used AItaVista to search for information an three assigned search topics graded in terms of complexity. Five hundred seven search queries were factor analyzed to identify relationships between the individual difference variables and Boolean and best-match search strategies. A number of consistent patterns of relationship were found. As task complexity increased, a number of strategic shifts were also observed an the part of searchers possessing particular combinations of characteristics. A second article (published in this issue of JASIST; Ford, Miller, & Moss, 2005) presents a combined analyses of the data including a series of regression analyses.

Abstract

This is the second of two articles published in this issue of JASIST reporting the results of a study investigating relationships between Web search strategies and a range of human individual differences. In this article we provide a combined analysis of the factor analyses previously presented separately in relation to each of three groups of human individual difference (study approaches, cognitive and demographic features, and perceptions of and approaches to Internet-based information seeking). It also introduces two series of regression analyses conducted an data spanning all three individual difference groups. The results are discussed in terms of the extent to which they satisfy the original aim of this exploratory research, namely to identify any relationships between search strategy and individual difference variables for which there is a prima facie case for more focused systematic study. It is argued that a number of such relationships do exist. The results of the project are summarized and suggestions are made for further research.

Abstract

Authority records were compared for established headings that are identical in LCSH (18th ed.) and Moving Image Materials (MIM). The Use For, Broader Term, Narrower Term, and Related Term references in the LCSH authority file were compared with their counterparts in MIM, to determine the proportion of duplication existing between them. Fewer that 10% of these reference headings are identical. A qualitative comparison was made of the 'semantic spaces' inhibited by identical headings in different contexts: a general purpose subject access list is compared with a medium specific form and genre access list. It was found that, in many cases, headings that are identical as character strings have markedly differnt meanings in different contexts. The conclusion offered is that, both quantitatively and qualitatively, pairs of identical headings differ sufficiently from each other that the creation of authority records for each usage represents no duplication in any meaningful sense. The striking divergence, in many instances, between semantic spaces poses intellectual questions regarding the differences between the meaning of subjects and of forms and genres

Abstract

Purpose - A common criticism of research into information seeking on the internet is that information seekers are restricted by the demands of the researcher. Another criticism is that the search topics, are often imposed by the researcher, and; particularly when working with children, domain knowledge could be as important as information-seeking skills. The research reported here attempts to address both these problems. Design/methodology/approach - A total of 15 children, aged 11 to 16, were each set three "think aloud" internet searches. In the first, they were asked to recall the last time they had sought information on the internet, and to repeat the search. For the second, they were given a word, asked to interpret it, then asked to search for their interpretation. For the third, they were asked to recall the last time they had been unsuccessful in a search, and to repeat the search. While performing each task, the children were encouraged to explain their actions. Findings - The paper finds that the factors that determined a child's ability to search successfully appeared to be: the amount of experience the child had of using the internet; the amount of guidance, both from adults and from peers; and the child's ability to explore the virtual environment, and to use the tools available for so doing. Originality/value - Many of the searches performed by participants in this paper were not related to schoolwork, and so some of the search approaches differed from those taught by teachers. Instead, they evolved through exploration and exchange of ideas. Further studies of this sort could provide insights of value to designers of web environments.

Abstract

Some LCSH have the potential to be used for either subject or form/genre access. A selection of LCSH, cognates with terms from Moving image materials: Genre terms, was searched in OCLC's OLUC to determine the degrees to which they were used for each of these two types of access. it was discovered that the set of 'subject headings' under study was used for form/genre access between 6% and 99% of the time, with a mean average of just over 50%. The guidance provided to catalogers by information contained in LoC authority records is also discussed

Abstract

This article reports the results of a study of the role of individual differences in Internet searching. The dimensions of individual differences forming the focus of the research consisted of: cognitive styles; levels of prior experience; Internet perceptions; study approaches; age; and gender. Sixty-nine Masters students searched for information on a prescribed topic using the AItaVista search engine. Results were assessed using simple binary relevance judgements. Factor analysis and multiple regression revealed interesting differences, retrieval effectiveness being linked to: male gender; low cognitive complexity; an imager (as opposed to verbalizer) cognitive style; and a number of Internet perceptions and study approaches grouped here as indicating low self-efficacy. The implications of these findings for system development and for future research are discussed.

Abstract

In this issue Ford, Miller and Moss utilize 68 volunteers from a population of 250 Master's students to complete on the web three search tasks with clear fact based goals and three or less facets. One task required broadening the search concepts from those given, a second provided a specific terminology for one facet but required a second facet that would require translation, and the third required general to specific transformation. The students were measured as to their performance on Entewistle's Revised Inventory of Approaches to Studying providing values for ten study variables and asked to assess their experience on the Internet, with Alta Vista, and with Boolean search. Searches were conducted on Alta Vista using Netscape Navigator 4 with participants free to choose and switch Boolean, best match or combined search modes at will while a front end script recorded all submitted searches and help access. Search related variables extracted were from Boolean only queries, best match only queries, and combined queries. Factor analyses were conducted on all variables for each search mode for each search. In task one Boolean is differentiated from best match search by sharing high loads on active interest, intention to reproduce, fear of failure, and relating ideas. The combined searcher is linked with the best match searcher with low active interest, low intention to reproduce and low fear of failure. In task 2 Boolean is differentiated from best match search by sharing high loads on intention to reproduce and low on intention to understand. Best match loads positively with intention to understand and negatively with intention to reproduce. Combined searching linked with both good and with poor time management. In task 3 the loads mimic task 1. It seems Boolean is consistently linked to a reproductive rather than a meaning seeking approach, but also with high levels of interest and fear of failure. Best match associates with the converse of these measures.

Abstract

This paper reports the results of a study funded by the Arts and Humanities Research Board which sought to investigate links between Web search strategies and retrieval effectiveness. A total of 68 students, enrolled on masters programmes in librarianship, information management and information systems, searched for two topics using the AltaVista search engine. Logs of the resultant 341 queries, along with relevance judgements for over 4,000 retrieved items, were analysed using factor analysis and regression. The differing but complementary types and strengths of evidence produced by these two forms of analysis are discussed and presented. Retrieval effectiveness was associated positively with best-match searching and negatively with Boolean searching. The implications of these findings for Web searching are discussed.
