- Abstract
- Indexing and abstracting are not activities that should be looked upon as ends in themselves. It is the results of these activities that should be evaluated and this can only be done within the context of a particular database, whether in printed or machine-readable form. In this context, the indexing can be judged successful if it allows searchers to locate items they want without having to look at many they do not want. This book intended primarily as a text to be used in teaching indexing and abstracting of Library and information science. It is an immense value to all individuals and institutions involved in information retrieval and related activities, including librarians, managers of information centres and database producers.

- 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
- 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
- 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
- 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
- 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
- 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
