1Spina, D. ; Trippas, J.R. ; Cavedon, L. ; Sanderson, M.: Extracting audio summaries to support effective spoken document search.
In: Journal of the Association for Information Science and Technology. 68(2017) no.9, S.2101-2115.
Abstract: We address the challenge of extracting query biased audio summaries from podcasts to support users in making relevance decisions in spoken document search via an audio-only communication channel. We performed a crowdsourced experiment that demonstrates that transcripts of spoken documents created using Automated Speech Recognition (ASR), even with significant errors, are effective sources of document summaries or "snippets" for supporting users in making relevance judgments against a query. In particular, the results show that summaries generated from ASR transcripts are comparable, in utility and user-judged preference, to spoken summaries generated from error-free manual transcripts of the same collection. We also observed that content-based audio summaries are at least as preferred as synthesized summaries obtained from manually curated metadata, such as title and description. We describe a methodology for constructing a new test collection, which we have made publicly available.

2Wilson, M.J. ; Wilson, M.L.: ¬A comparison of techniques for measuring sensemaking and learning within participant-generated summaries.
In: Journal of the American Society for Information Science and Technology. 64(2013) no.2, S.291-306.
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.

4Alonso, M.I. ; Fernández, L.M.M.: Perspectives of studies on document abstracting : towards an integrated view of models and theoretical approaches.
In: Journal of documentation. 66(2010) no.4, S.563-584.
Abstract: Purpose - The aim of this paper is to systemize and improve the scientific status of studies on document abstracting. This is a diachronic, systematic study of document abstracting studies carried out from different perspectives and models (textual, psycholinguistic, social and communicative). Design/methodology/approach - A review of the perspectives and analysis proposals which are of interest to the various theoreticians of abstracting is carried out using a variety of techniques and approaches (cognitive, linguistic, communicative-social, didactic, etc.), each with different levels of theoretical and methodological abstraction and degrees of application. The most significant contributions of each are reviewed and highlighted, along with their limitations. Findings - It is found that the great challenge in abstracting is the systemization of models and conceptual apparatus, which open up this type of research to semiotic and socio-interactional perspectives. It is necessary to carry out suitable empirical research with operative designs and ad hoc measuring instruments which can measure the efficiency of the abstracting and the efficiency of a good abstract, while at the same time feeding back into the theoretical baggage of this type of study. Such research will have to explain and provide answers to all the elements and variables, which affect the realization and the reception of a quality abstract. Originality/value - The paper provides a small map of the studies on document abstracting. This shows how the conceptual and methodological framework has extended at the same time as the Science of Documentation has been evolving. All the models analysed - the communicative and interactional approach - are integrated in a new systematic framework.

Abstract: Despite their changing role, abstracts remain useful in the digital world. Aimed at both information professionals and researchers who work and publish in different fields, this book summarizes the most important and up-to-date theory of abstracting, as well as giving advice and examples for the practice of writing different kinds of abstracts. The book discusses the length, the functions and basic structure of abstracts. A new approach is outlined on the questions of informative and indicative abstracts. The abstractors' personality, their linguistic and non-linguistic knowledge and skills are also discussed with special attention. The process of abstracting, its steps and models, as well as recipient's role are treated with special distinction. Abstracting is presented as an aimed (purported) understanding of the original text, its interpretation and then a special projection of the information deemed to be worth of abstracting into a new text.Despite the relatively large number of textbooks on the topic there is no up-to-date book on abstracting in the English language. In addition to providing a comprehensive coverage of the topic, the proposed book contains novel views - especially on informative and indicative abstracts. The discussion is based on an interdisciplinary approach, blending the methods of library and information science and linguistics. The book strives to a synthesis of theory and practice. The synthesis is based on a large and existing body of knowledge which, however, is often characterised by misleading terminology and flawed beliefs.

6Hartley, J. ; Betts, L.: Common weaknesses in traditional abstracts in the social sciences.
In: Journal of the American Society for Information Science and Technology. 60(2009) no.10, S.2010-2018.
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.
7Koltay, T.: Abstracting: information literacy on a professional level.
In: Journal of documentation. 65(2009) no.5, S.841-855.
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.
8Sauperl, A. ; Klasinc, J. ; Luzar, S.: Components of abstracts : logical structure of scholarly abstracts in pharmacology, sociology, and linguistics and literature.
In: Journal of the American Society for Information Science and Technology. 59(2008) no.9, S.1420-1432.
Abstract: The international standard ISO 214:1976 defines an abstract as "an abbreviated, accurate representation of the contents of a document" (p. 1) that should "enable readers to identify the basic content of a document quickly and accurately to determine relevance" (p. 1). It also should be useful in computerized searching. The ISO standard suggests including the following elements: purpose, methods, results, and conclusions. Researchers have often challenged this structure and found that different disciplines and cultures prefer different information content. These claims are partially supported by the findings of our research into the structure of pharmacology, sociology, and Slovenian language and literature abstracts of papers published in international and Slovenian scientific periodicals. The three disciplines have different information content. Slovenian pharmacology abstracts differ in content from those in international periodicals while the differences between international and Slovenian abstracts are small in sociology. In the field of Slovenian language and literature, only domestic abstracts were studied. The identified differences can in part be attributed to the disciplines, but also to the different role of journals and papers in the professional society and to differences in perception of the role of abstracts. The findings raise questions about the structure of abstracts required by some publishers of international journals.

9Hartley, J. ; Betts, L.: Revising and polishing a structured abstract : is it worth the time and effort?.
In: Journal of the American Society for Information Science and Technology. 59(2008) no.12, S.1870-1877.
Abstract: Many writers of structured abstracts spend a good deal of time revising and polishing their texts - but is it worth it? Do readers notice the difference? In this paper we report three studies of readers using rating scales to judge (electronically) the clarity of an original and a revised abstract, both as a whole and in its constituent parts. In Study 1, with approximately 250 academics and research workers, we found some significant differences in favor of the revised abstract, but in Study 2, with approximately 210 information scientists, we found no significant effects. Pooling the data from Studies 1 and 2, however, in Study 3, led to significant differences at a higher probability level between the perception of the original and revised abstract as a whole and between the same components as found in Study 1. These results thus indicate that the revised abstract as a whole, as well as certain specific components of it, were judged significantly clearer than the original one. In short, the results of these experiments show that readers can and do perceive differences between original and revised texts - sometimes - and that therefore these efforts are worth the time and effort.
10Bowman, J.H.: Annotation: a lost art in cataloguing.
In: Cataloging and classification quarterly. 44(2007) nos.1/2, S.95-111.
Abstract: Public library catalogues in early twentieth-century Britain frequently included annotations, either to clarify obscure titles or to provide further information about the subject-matter of the books they described. Two manuals giving instruction on how to do this were published at that time. Following World War I, with the decline of the printed catalogue, this kind of annotation became rarer, and was almost confined to bulletins of new books. The early issues of the British National Bibliography included some annotations in exceptional cases. Parallels are drawn with the provision of table-of-contents information in present-day OPAC's.

11Montesi, M. ; Mackenzie Owen, J.: Revision of author abstracts : how it is carried out by LISA editors.
In: Aslib proceedings. 59(2007) no.1, S.26-45.
Abstract: Purpose - The literature on abstracts recommends the revision of author supplied abstracts before their inclusion in database collections. However, little guidance is given on how to carry out such revision, and few studies exist on this topic. The purpose of this research paper is to first survey 187 bibliographic databases to ascertain how many did revise abstracts, and then study the practical amendments made by one of these, i.e. LISA (Library and Information Science Abstracts). Design/methodology/approach - Database policies were established by e-mail or through alternative sources, with 136 databases out of 187 exhaustively documented. Differences between 100 author-supplied abstracts and the corresponding 100 LISA amended abstracts were classified into sentence-level and beyond sentence-level categories, and then as additions, deletions and rephrasing of text. Findings - Revision of author abstracts was carried out by 66 databases, but in just 32 cases did it imply more than spelling, shortening of length and formula representation. In LISA, amendments were often non-systematic and inconsistent, but still pointed to significant aspects which were discussed. Originality/value - Amendments made by LISA editors are important in multi- and inter-disciplinary research, since they tend to clarify certain aspects such as terminology, and suggest that abstracts should not always be considered as substitutes for the original document. From this point-of-view, the revision of abstracts can be considered as an important factor in enhancing a database's quality.
12Hartley, J. ; Betts, L.: ¬The effects of spacing and titles on judgments of the effectiveness of structured abstracts.
In: Journal of the American Society for Information Science and Technology. 58(2007) no.14, S.2335-2340.
Abstract: Previous research assessing the effectiveness of structured abstracts has been limited in two respects. First, when comparing structured abstracts with traditional ones, investigators usually have rewritten the original abstracts, and thus confounded changes in the layout with changes in both the wording and the content of the text. Second, investigators have not always included the title of the article together with the abstract when asking participants to judge the quality of the abstracts, yet titles alert readers to the meaning of the materials that follow. The aim of this research was to redress these limitations. Three studies were carried out. Four versions of each of four abstracts were prepared. These versions consisted of structured/traditional abstracts matched in content, with and without titles. In Study 1, 64 undergraduates each rated one of these abstracts on six separate rating scales. In Study 2, 225 academics and research workers rated the abstracts electronically, and in Study 3, 252 information scientists did likewise. In Studies 1 and 3, the respondents rated the structured abstracts significantly more favorably than they did the traditional ones, but the presence or absence of titles had no effect on their judgments. In Study 2, no main effects were observed for structure or for titles. The layout of the text, together with the subheadings, contributed to the higher ratings of effectiveness for structured abstracts, but the presence or absence of titles had no clear effects in these experimental studies. It is likely that this spatial organization, together with the greater amount of information normally provided in structured abstracts, explains why structured abstracts are generally judged to be superior to traditional ones.
13Wang, F.L. ; Yang, C.C.: ¬The impact analysis of language differences on an automatic multilingual text summarization system.
In: Journal of the American Society for Information Science and Technology. 57(2006) no.5, S.684-696.
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.

14Cross, C. ; Oppenheim, C.: ¬A genre analysis of scientific abstracts.
In: Journal of documentation. 62(2006) no.4, S.428-446.
Abstract: Purpose - The purpose of the paper is to analyse the structure of a small number of abstracts that have appeared in the CABI database over a number of years, during which time the authorship of the abstracts changed from CABI editorial staff to journal article authors themselves. This paper reports a study of the semantic organisation and thematic structure of 12 abstracts from the field of protozoology in an effort to discover whether these abstracts followed generally agreed abstracting guidelines. Design/methodology/approach - The method adopted was a move analysis of the text of the abstracts. This move analysis revealed a five-move pattern: move 1 situates the research within the scientific community; move 2 introduces the research by either describing the main features of the research or presenting its purpose; move 3 describes the methodology; move 4 states the results; and move 5 draws conclusions or suggests practical applications. Findings - Thematic analysis shows that scientific abstract authors thematise their subject by referring to the discourse domain or the "real" world. Not all of the abstracts succeeded in following the guideline advice. However, there was general consistency regarding semantic organisation and thematic structure. Research limitations/implications - The research limitations were the small number of abstracts examined, from just one subject domain. Practical limitations - The practical implications are the need for abstracting services to be clearer and more prescriptive regarding how they want abstracts to be structured as the lack of formal training in abstract writing increases the risk of subjectivity and verbosity and reduces clarity in scientific abstracts. Another implication of the research are that abstracting and indexing services must ensure that they maintain abstract quality if they introduce policies of accepting author abstracts. This is important as there is probably little formal training in abstract writing for science students at present. Recommendations for further research are made. Originality/value - This paper reports a study of the semantic organisation and thematic structure of 12 abstracts from the field of protozoology.

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.
16Montesi, M. ; Urdiciain, B.G.: Recent linguistic research into author abstracts : its value for information science.
In: Knowledge organization. 32(2005) no.2, S.64-78.
Abstract: This paper is a review of genre analysis of author abstracts carried out in the area of English for Special Purposes (ESP) since 1990. Given the descriptive character of such analysis, it can be valuable for Information Science (IS), as it provides a picture of the variation in author abstracts, depending an the discipline, culture and language of the author, and the envisaged context. The authors claim that such knowledge can be useful for information professionals who need to revise author abstracts, or use them for other activities in the organization of knowledge, such as subject analysis and control of vocabulary. With this purpose in mind, we summarize various findings of ESP research. We describe how abstracts vary in structure, content and discourse, and how linguists explain such variations. Other factors taken into account are the stylistic and discoursal features of the abstract, lexical choices, and the possible sources of blas. In conclusion, we show how such findings can have practical and theoretical implications for IS.

Abstract: We investigated an approach to automatic discourse parsing of sociology dissertation abstracts as a sentence categorization task. Decision tree induction was used for the automatic categorization. Three models were developed. Model 1 made use of word tokens found in the sentences. Model 2 made use of both word tokens and sentence position in the abstract. In addition to the attributes used in Model 2, Model 3 also considered information regarding the presence of indicator words in surrounding sentences. Model 3 obtained the highest accuracy rate of 74.5 % when applied to a test sample, compared to 71.6% for Model 2 and 60.8% for Model 1. The results indicated that information about sentence position can substantially increase the accuracy of categorization, and indicator words in earlier sentences (before the sentence being processed) also contribute to the categorization accuracy.
Inhalt: 1. Introduction This paper reports our initial effort to develop an automatic method for parsing the discourse structure of sociology dissertation abstracts. This study is part of a broader study to develop a method for multi-document summarization. Accurate discourse parsing will make it easier to perform automatic multi-document summarization of dissertation abstracts. In a previous study, we determined that the macro-level structure of dissertation abstracts typically has five sections (Khoo et al., 2002). In this study, we treated discourse parsing as a text categorization problem - assigning each sentence in a dissertation abstract to one of the five predefined sections or categories. Decision tree induction, a machine-learning method, was applied to word tokens found in the abstracts to construct a decision tree model for the categorization purpose. Decision tree induction was selected primarily because decision tree models are easy to interpret and can be converted to rules that can be incorporated in other computer programs. A well-known decision-tree induction program, C5.0 (Quinlan, 1993), was used in this study.

18Kuhlen, R.: Informationsaufbereitung III : Referieren (Abstracts - Abstracting - Grundlagen).
In: Grundlagen der praktischen Information und Dokumentation. 5., völlig neu gefaßte Ausgabe. 2 Bde. Hrsg. von R. Kuhlen, Th. Seeger u. D. Strauch. Begründet von Klaus Laisiepen, Ernst Lutterbeck, Karl-Heinrich Meyer-Uhlenried. Bd.1: Handbuch zur Einführung in die Informationswissenschaft und -praxis. München : Saur, 2004. S.189-206.
Abstract: Was ein Abstract (im Folgenden synonym mit Referat oder Kurzreferat gebraucht) ist, legt das American National Standards Institute in einer Weise fest, die sicherlich von den meisten Fachleuten akzeptiert werden kann: "An abstract is defined as an abbreviated, accurate representation of the contents of a document"; fast genauso die deutsche Norm DIN 1426: "Das Kurzreferat gibt kurz und klar den Inhalt des Dokuments wieder." Abstracts gehören zum wissenschaftlichen Alltag. Weitgehend allen Publikationen, zumindest in den naturwissenschaftlichen, technischen, informationsbezogenen oder medizinischen Bereichen, gehen Abstracts voran, "prefe-rably prepared by its author(s) for publication with it". Es gibt wohl keinen Wissenschaftler, der nicht irgendwann einmal ein Abstract geschrieben hätte. Gehört das Erstellen von Abstracts dann überhaupt zur dokumentarischen bzw informationswissenschaftlichen Methodenlehre, wenn es jeder kann? Was macht den informationellen Mehrwert aus, der durch Expertenreferate gegenüber Laienreferaten erzeugt wird? Dies ist nicht so leicht zu beantworten, zumal geeignete Bewertungsverfahren fehlen, die Qualität von Abstracts vergleichend "objektiv" zu messen. Abstracts werden in erheblichem Umfang von Informationsspezialisten erstellt, oft unter der Annahme, dass Autoren selber dafür weniger geeignet sind. Vergegenwärtigen wir uns, was wir über Abstracts und Abstracting wissen. Ein besonders gelungenes Abstract ist zuweilen klarer als der Ursprungstext selber, darf aber nicht mehr Information als dieser enthalten: "Good abstracts are highly structured, concise, and coherent, and are the result of a thorough analysis of the content of the abstracted materials. Abstracts may be more readable than the basis documents, but because of size constraints they rarely equal and never surpass the information content of the basic document". Dies ist verständlich, denn ein "Abstract" ist zunächst nichts anderes als ein Ergebnis des Vorgangs einer Abstraktion. Ohne uns zu sehr in die philosophischen Hintergründe der Abstraktion zu verlieren, besteht diese doch "in der Vernachlässigung von bestimmten Vorstellungsbzw. Begriffsinhalten, von welchen zugunsten anderer Teilinhalte abgesehen, abstrahiert' wird. Sie ist stets verbunden mit einer Fixierung von (interessierenden) Merkmalen durch die aktive Aufmerksamkeit, die unter einem bestimmten pragmatischen Gesichtspunkt als wesentlich' für einen vorgestellten bzw für einen unter einen Begriff fallenden Gegenstand (oder eine Mehrheit von Gegenständen) betrachtet werden". Abstracts reduzieren weniger Begriffsinhalte, sondern Texte bezüglich ihres proportionalen Gehaltes. Borko/ Bernier haben dies sogar quantifiziert; sie schätzen den Reduktionsfaktor auf 1:10 bis 1:12

Abstract: Bericht über die Integration von Abstracts in den Katalog
Inhalt: "Der etwas provokante Titel soll keineswegs eine Dichotomie zwischen bibliothekarischer und nutzerorientierter Erschließung implizieren, sondern zwei Fragen stellen: Was suchen Nutzer in Bibliotheken? Was wollen Nutzer wissen? Die Antwort darauf wird immer heißen: Nutzer suchen nach Inhalten und wollen Informationen über Inhalte. Formale Aspekte, die unter bibliothekarischen Gesichtspunkten durchaus bedeutend sind, spielen für den Nutzer keine große Rolle, Schlagworte als Instrumente der verbalen Sacherschließung beschreiben Inhalte häufig unzureichend und sind für Nutzer vielfach unverständlich. Die bunten Kataloge der Internet-Buchhändler stellen zunehmend einen Kontrast, aber auch eine Konkurrenz zu unseren OPACs dar. Wer in diesen Katalogen recherchiert, findet zwar meist nur eine rudimentäre und natürlich bibliothekarischen Kriterien nicht entsprechende Titelbeschreibung, dafür jedoch regelmäßig zusätzliche Informationen wie Abstracts oder Verlagsinformationen, Rezensionen, Abbildungen, Textproben. Sollen wir uns nun den Katalog von Amazon.de (und seiner Konkurrenten) zum Vorbild nehmen? Wir meinen ja und erfassen daher Abstracts und andere Inhaltsinformationen, die wir mit unseren Titelaufnahmen im Verbund verlinken. Wir sehen darin eine Fortsetzung unseres seit einigen Jahren verfolgten Zieles, die traditionelle Sach- und Formalerschließung um neue Komponenten zu erweitern. Seit 1997 beteiligen wir uns an der kooperativen Aufsatzerschließung, insbesondere durch die Katalogisierung von Festschriftenaufsätzen. Aufsätze in fortlaufenden Sammelwerken katalogisieren wir nur ausnahmsweise, jedoch weisen wir von den Verlagen im Internet angebotene Inhaltsinformationen über Zeitschriften (Inhaltsverzeichnisse, Abstracts, Volltexte) auf der lokalen Ebene nach. Mit unserem Versuch, Abstracts in eine Datenbank des Verbundes einzustellen, haben wir Ende 2000 begonnen. Von ausgewählten Monographien werden Klappentexte, Verlagsinformationen und Abstracts erfasst und mit der Titelaufnahme verlinkt. Unser bisheriges Verfahren ist handgestrickt - hat aber den Vorteil, dass es ohne zusätzliche Technik auskommt und unmittelbar umsetzbar ist: In einem ersten Schritt werden Klappentexte und Inhaltsinformationen von geeigneten Werken ausgewählt. Die Auswahl berücksichtigt sowohl die Bedeutung des Buches wie Umfang und Qualität der Inhaltsinformationen. Das Erfassen der Texte geschieht durch Einscannen oder - wenn dies bei kurzen Texten effizienter ist - durch Abschreiben. Bei einzelnen Verlagen ist es möglich, die Texte direkt von den Webseiten des Verlages per copy-and-paste zu übernehmen. Die Doktoranden unserer Fakultät bitten wir um die Lieferung des Abstracts als Textdatei. Die durch Einscannen, Abschreiben oder Kopieren erzeugte Textdatei wird im nächsten Schritt in eine vom BSZ entwickelte Muster-HTML-Datei kopiert, konvertiert und mit der SWBIdentnummer versehen. Anschließend senden wir diese Datei per E-Mail an den Verbund. Der Verbund stellt unsere Dateien in den BSZ-Medienserver (http://www.bszbw.de/diglib/medserv/metainfhtml) ein, auf dem z.B. auch die ebenfalls mit den VerbundTiteldaten verlinkten IfB- und ekz-Rezensionen gespeichert werden."

20Pinto, M.: Abstracting/abstract adaptation to digital environments : research trends.
In: Journal of documentation. 59(2003) no.5, S.581-608.
Abstract: The technological revolution is affecting the structure, form and content of documents, reducing the effectiveness of traditional abstracts that, to some extent, are inadequate to the new documentary conditions. Aims to show the directions in which abstracting/abstracts can evolve to achieve the necessary adequacy in the new digital environments. Three researching trends are proposed: theoretical, methodological and pragmatic. Theoretically, there are some needs for expanding the document concept, reengineering abstracting and designing interdisciplinary models. Methodologically, the trend is toward the structuring, automating and qualifying of the abstracts. Pragmatically, abstracts networking, combined with alternative and complementary models, open a new and promising horizon. Automating, structuring and qualifying abstracting/abstract offer some short-term prospects for progress. Concludes that reengineering, networking and visualising would be middle-term fruitful areas of research toward the full adequacy of abstracting in the new electronic age.
