- Abstract
- Structured abstracts are abstracts which include subheadings such as: background, aims, participants methods and results. These are rapidly replacing traditional abstracts in medical periodicals, but the number and detail of the subheadings used varies, and there is a range of different typographic settings. Reviews a number of studies designed to investigate readers' preferences for different typographic settings and layout. Over 400 readers took part in the study: students; postgraduates; research workers and academics in the social sciences. The most preferred version emerged from the last of 3 studies and 2 additional studies were then carried out to determine preferences for the overall position and layout of this most preferred version on a A4 page. The most preferred version for the setting of the subheadings are printed in bold capital letters

- Abstract
- Considers the principles of indexing and the intellectual skills involved in order to determine what automatic indexing systems would be required in order to supplant or complement the human indexer. Good indexing requires: considerable prior knowledge of the literature; judgement as to what to index and what depth to index; reading skills; abstracting skills; and classification skills, Illustrates these features with a detailed description of abstracting and indexing processes involved in generating entries for the mechanical engineering database POWERLINK. Briefly assesses the possibility of replacing human indexers with specialist indexing software, with particular reference to the Object Analyzer from the InTEXT automatic indexing system and using the criteria described for human indexers. At present, it is unlikely that the automatic indexer will replace the human indexer, but when more primary texts are available in electronic form, it may be a useful productivity tool for dealing with large quantities of low grade texts (should they be wanted in the database)

- 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
- Reference librarians, who are thoroughly familiar with the purpose, scope and arrangement of abstract periodicals, are uniquely qualified for the task of writing abstracts. The procedures described here offer a relatively simple way for them to write acceptable abstracts from the outset. Although research is being conducted in the area of machine generated abstracts, there wll continue to be a role for human abstractors.

- Abstract
- Graph-based ranking algorithms have recently been proposed for single document summarizations and such algorithms evaluate the importance of a sentence by making use of the relationships between sentences in the document in a recursive way. In this paper, we investigate using other related or relevant documents to improve summarization of one single document based on the graph-based ranking algorithm. In addition to the within-document relationships between sentences in the specified document, the cross-document relationships between sentences in different documents are also taken into account in the proposed approach. We evaluate the performance of the proposed approach on DUC 2002 data with the ROUGE metric and results demonstrate that the cross-document relationships between sentences in different but related documents can significantly improve the performance of single document summarization.

- Abstract
- Purpose - This paper aims to argue for a conception of information literacy (IL) that goes beyond the abilities of finding information as it includes communication skills. An important issue in this is that abstractors exercise IL on a professional level. Design/methodology/approach - By stressing the importance of the fact that information literacy extends towards verbal communication the paper takes an interdisciplinary approach, the main component of which is linguistics. Findings - It is found that verbal communication and especially analytic-synthetic writing activities play an important role in information literacy at the level of everyday language use, semi-professional and professional summarising of information. The latter level characterises abstracting. Originality/value - The paper adds to the body of knowledge about information literacy in general and in connection with communication and abstracting.

- Abstract
- Reports results of a study, conducted by the European Society of Paediatric Research (ESPR), to determine whether the information content of structured medical abstracts is greater than abstracts with traditional format and whether the efficacy of peer review is improved by the use of structured medical abstracts. The sample studied comprised the abstracts of papers submitted for the ESPR annual meeting and each abstract was assessed by a research worker by a research worker for information content by referring to a list of criteria. The words in each abstract were counted to obtain the information density of each and the abstracts were evaluated according to whether they were in an unstructured format, a semistructured format, or a more fully structured format. Although there was no significant difference in the scientific score of the scientific information density of the different formats there was significantly more information in the fully structured format. When the abstracts were resubmitted in structured format, there was always a highly significant increase in the information content

- 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
- The indexing process consists of the comprehension of the document to be indexed, followed by the production of a set of index terms. Differences between academic indexing and back-of-the-book indexing are discussed. Text comprehension is a branch of human information processing, and it is argued that the model of text comprehension and production debeloped by van Dijk and Kintsch can form the basis for a cognitive process model of indexing. Strategies for testing such a model are suggested

- 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
- The library and information science (LIS) literature on abstracting makes little mention about abstracting conducted in the corporate / business environment, whereas the business literature suggests that abstarcting is a very important component of business writing. Examines a variety of publications from LIS and business in order to compare and contrast their approaches to the following aspects of abstracting: definitions of abstracts; types of abstracts; purpose of abstracts; and writing of abstracts. Summarises the results of the examination which revealed a number of similarities, differences, and inadequacies in the ways in which both fields approach abstracting. Concludes that both fields need to develop more detailed guidelines concerning the cognitive process of abstracting and suggests improvements to the training af absractors based on these findings

- Abstract
- Reports on a comparison of the "content categories" listed in the ANSI/ISO abstracting standards to actual content found in abstracts from the sciences, social sciences, and the humanities. The preliminary findings question the fundamental concept underlying these standards, namely, that any one set of standards and generalized instructions can describe and elicit the optimal configuration for abstracts from all subject areas

- Abstract
- While it is easy to identify whether someone has found a piece of information during a search task, it is much harder to measure how much someone has learned during the search process. Searchers who are learning often exhibit exploratory behaviors, and so current research is often focused on improving support for exploratory search. Consequently, we need effective measures of learning to demonstrate better support for exploratory search. Some approaches, such as quizzes, measure recall when learning from a fixed source of information. This research, however, focuses on techniques for measuring open-ended learning, which often involve analyzing handwritten summaries produced by participants after a task. There are two common techniques for analyzing such summaries: (a) counting facts and statements and (b) judging topic coverage. Both of these techniques, however, can be easily confounded by simple variables such as summary length. This article presents a new technique that measures depth of learning within written summaries based on Bloom's taxonomy (B.S. Bloom & M.D. Engelhart, 1956). This technique was generated using grounded theory and is designed to be less susceptible to such confounding variables. Together, these three categories of measure were compared by applying them to a large collection of written summaries produced in a task-based study, and our results provide insights into each of their strengths and weaknesses. Both fact-to-statement ratio and our own measure of depth of learning were effective while being less affected by confounding variables. Recommendations and clear areas of future work are provided to help continued research into supporting sensemaking and learning.
