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

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

Summarizing is the process of reducing the large information size of something like a novel or a scientific paper to a short summary or abstract comprising only the most essential points. Summarizing is frequent in everyday communication, but it is also a professional skill for journalists and others. Automated summarizing functions are urgently needed by Internet users who wish to avoid being overwhelmed by information. This book presents the state of the art and surveys related research; it deals with everyday and professional summarizing as well as computerized approaches. The author focuses in detail on the cognitive pro-cess involved in summarizing and supports this with a multimedia simulation systems on the accompanying CD-ROM

Abstract

As a result of the transition to full-text storage, multimedia and networking, information systems are becoming more efficient but at the same time more difficult to use, in particular because users are confronted with information volumes that increasingly exceed individual processing capacities. Consequently, there is an increase in the demand for user aids such as summarising techniques. Against this background, the interdisciplinary Dagstuhl Seminar 'Summarising Text for Intelligent Communication' (Dec. 1993) outlined the academic state of the art with regard to summarising (abstracting) and proposed future directions for research and system development. Research is currently shifting its attention from text summarising to summarising states of affairs. Recycling solutions are put forward in order to satisfy short-term needs for summarisation products. In the medium and long term, it is necessary to devise concepts and methods of intelligent summarising which have a better formal and empirical grounding and a more modular organisation

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
