- Abstract
- Clear guidelines have been provided for structuring the abstracts of original research and review articles and, in the past 10 years, several major medical periodicals have adopted the policy of including such abstracts with all their articles. A review of the literature reveals that proponents claim that structured abstracts enhance peer review, improve information retrieval, and ease critical appraisal. However, some periodicals have not adopted structured abstracts and their opponents claim that they make articles longer and harder to read and restrict author originality. Concludes that previous research on structured abstracts focused on how closely they followed prescribed structure and include salient points of the full text, rather than their role in increasing the usefulness of the article

- Abstract
- Comments on the value of abstracts or summary notes to information available online via the Internet and WWW and concludes that automated abstracting techniques would be highly useful if routinely applied to cataloguing or metadata for Internet documents and documents in other databases. Information seekers need external summary information to assess content and value of retrieved documents. Examines traditional models for writers, in library audiovisual cataloguing, periodical databases and archival work, along with innovative new model databases featuring robust cataloguing summaries. Notes recent developments in automated techniques, computational research, and machine summarization of digital images. Recommendations are made for future designers of cataloguing and metadata standards

- Abstract
- Die Qualität der Dokumentenanlyse entscheidet über die Wirksamkeit eines Dokumentationsvorhabens, denn Auswahl und Darstellung von Informationselementen bilden die Grundlage zum Wiederfinden des dokumentierten Wissens. Kurzreferate informieren über den Inhalt einer Veröffentlichung. Verschiedene Typen von Inhaltsangaben werden entsprechend der DIN 1426 vorgestellt, Vorschriften und Anweisungen an Referate werden analysiert und die Bewertung der Qualität von Kurzreferaten diskutiert. Das zunehmende Wissen über den Aufbau und das Information Retrieval von Faktendatenbanken führt zu der Schlußfolgerung, daß über die verbale Kurzdarstellung des Dokumenteninhalts hinaus Fakten extrahiert und in speziellen Datenbanken gespeichert werden sollten

- Abstract
- Based on the salient features of the documents, automatic text summarization systems extract the key sentences from source documents. This process supports the users in evaluating the relevance of the extracted documents returned by information retrieval systems. Because of this tool, efficient filtering can be achieved. Indirectly, these systems help to resolve the problem of information overloading. Many automatic text summarization systems have been implemented for use with different languages. It has been established that the grammatical and lexical differences between languages have a significant effect on text processing. However, the impact of the language differences on the automatic text summarization systems has not yet been investigated. The authors provide an impact analysis of language difference on automatic text summarization. It includes the effect on the extraction processes, the scoring mechanisms, the performance, and the matching of the extracted sentences, using the parallel corpus in English and Chinese as the tested object. The analysis results provide a greater understanding of language differences and promote the future development of more advanced text summarization techniques.

- Abstract
- Abstracts from 7 Internet subject trees (Euroferret, Excite, Infoseek, Lycos Top 5%, Magellan, WebCrawler, Yahoo!), 5 Internet subject gateways (ADAM, EEVL, NetFirst, OMNI, SOSIG), and 3 online databases (ERIC, ISI, LISA) were examined for their subject content, treatment of various enriching features, physical properties such as overall length, anf their readability. Considerable differences were measured, and consistent similarities among abstracts from each type of source were demonstrated. Internet subject tree abstracts were generally the shortest, and online database abstracts the longest. Subject tree and online database abstracts were the most informative, but the level of coverage of document features such as tables, bibliographies, and geographical constraints were disappointingly poor. On balance, the Internet gateways appeared to be providing the most satisfactory abstracts. The authors discuss the continuing role in networked information retrieval of abstracts and their functional analoques such as metadata

- Abstract
- A survey of abstracting policies by producers of bibliographical databases examined abstracting guidelines which aim to enhance free- text retrieval. Of the 123 database policies examined, fifty-seven (46 per cent) included such instructions. Editors consider contents of abstracts and their language as a primary factor in retrieval enhancement. Most recommend that once abstractors decide which concepts to include in abstracts and in which form to represent them, these terms should be co-ordinated with index terms assigned from a controlled vocabulary. Guidelines about the type of abstracts, i.e., informative or indicative, and about their length are not affected by the capability of free-text retrieval

- 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 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
- Detailed checklists and questionnaires have been used in the past to assess the quality of structured abstracts in the medical sciences. The aim of this article is to report the findings when a simpler checklist was used to evaluate the quality of 100 traditional abstracts published in 53 different social science journals. Most of these abstracts contained information about the aims, methods, and results of the studies. However, many did not report details about the sample sizes, ages, or sexes of the participants, or where the research was carried out. The correlation between the lengths of the abstracts and the amount of information present was 0.37 (p < .001), suggesting that word limits for abstracts may restrict the presence of key information to some extent. We conclude that authors can improve the quality of information in traditional abstracts in the social sciences by using the simple checklist provided in this article.
