Abstract

Reports results of 2 studies to determine if structured abstracts offer any advantage to users in terms of whether they are easier to search. In study 1, using a specially prepared electronic database of abstracts in either their original format or the structured format, 52 users were asked to find the answers to 2 questions for each of 8 abstracts in traditional format followed by 2 questions for each of 8 abstracts set in the structured format. Time and error data were recorded automatically. In study 2, using a printed database, 56 users were asked to to find 5 abstracts that reprted a particular kind of study and then find 5 more references that reported another kind of study. In study 1 users performed significantly faster and made fewer errors with structured abstracts but there were some unexplainable practice effects. In study 2, the users again performed significantly faster and made fewer errors with structured abstracts. However, there were asymmetrical transfer effects: users who responded first to the structured abstracts responded more quickly to the following traditional abstracts than did those users who responded first to the traditional abstracts. Nevertheless, the overall findings support the hypothesis that it is easier for user to search structured abstracts than it is to search traditional abstracts

Abstract

Presents a structured abstract of the actual article. Outlines the debate on the value of structured abstracts and describes a research project into their use, which investigated records of cardiovascular disease downloaded from MEDLINE and tested against clinical questions derived from a survey of CD-ROM use in 3 health science libraries. It was found that structured abstracts improve precision at the expense of recall and place heavier demands on the skills of selecting fields to search within the abstract. Indicates directions for further research

Abstract

Structured abstracts have now become widespread in medical research journals. Considers whether or not such structured abstracts can be used effectively in social science journals. Reviews a a selection of studies to see if structured abstracts written for social science journals are more informative, easier to read and easier to search than their traditional equivalents. Results suggest that structured abstracts are appropriate for social science journals. Editors of social science journals should consider adopting structured abstracts

Abstract

Reports results of a study to determine how easy and quickly research articles in library and information science could be retrieved from the LISA Plus CD-ROM database. Results show that the search with the descriptor 'research' retrieves all types of articles and it is necessary to read through every abstract to locate the research articles. The introductory sentence of a substantial number of abstracts hinder the process of identification since the sentence provides such information as the conference where the paper was presented, the special issue or the section of a periodical where the article is located; or obvious background information. Suggests measures whereby research articles can be identified easily and rapidly

Abstract

Reports results of a study to explore the possibilities of extending the use of structured abstracts (which use subheadings such as background, aims, participants method, results, conclusions) of the type often found in biomedical periodicals; to test whether or not such structured abstracts are more easily searched, comprehended and recalled than abstracts set in the traditional manner; and to examine readers' preferences for different typographic settings for structured abstracts. Results indicated: that it is possible to produce structured abstracts for periodical articles in the social sciences; and that such abstracts may be easier to read, search and recall than abstracts presented in the traditional manner. Suggests that abstracts use 6 subheadings (background, aims, method, results, conclusions, and, optionally, comment) and recommends that these subheadings are conveyed in bold capital letters and, ideally, set apart from the main text by printer's rules
