Abstract

Describes work carried out at doctoral level which investigated the ways in which journalists construct environmental news in Scotland. Focuses on the methods and tacit rules which reporters employ to locate, select and retrieve information for news stories. Journalists retrieve information from a complex range of sources. Addresses the information sources which are used in the news process. Examines the preference for human sources as opposed to library based information and discusses the influence of pragmatic constraints like time and space on the production of news

Abstract

Presents a method for the automated analysis and comprehension of foreign affairs news produced by a Chinese news agency. Notes that the development of the method was prededed by a study of the structuring rules of the news. Describes how an abstract of the news story is produced automatically from the analysis. Stresses the main aim of the work which is to use specch act theory to analyse and classify sentences

Abstract

Urges librarians engaged in bibliographical instruction to develop programmes in mass media news sources, and suggests how the theory of news framing and sourcing may be used to develop critical thinking, in particular for multicultural populations. Reports on a comparison of 2 news topics as they were covered by what are described as corporate news sources and independent non corporate sources. Suggests ways in which decisions about framing and sourcing can serve an ideological agenda that is not sensitive to multicultural viewpoints

"Wer im Jahr 2003 in seinen Lieblingsthemen detailliert informiert sein möchte, klappert täglich Dutzende von News-Sites und Webmagazinen ab. Ein Unterfangen, das mitunter recht mühselig sein kann: Neben, über und unter den gewünschten Nachrichten quälen sich bei jedem Aufruf Menüleisten, Banner und Grafiken durch die Leitung, und oft genug wurde die Seite seit seinem vergangenen Besuch nicht einmal aktualisiert. RSS-Clients, auch Feedreader genannt, könnten künftig Surfern die zeitaufwendige Handarbeit abnehmen. Das Prinzip ist denkbar einfach: Die Betreiber von Webangeboten stellen - neben den HTML-Seiten, die übliche Browser benötigen - einen so genannten Newsfeed zur Verfügung. Genau genommen handelt es sich dabei um nichts Weiteres. als eine speziell kodierte Textdatei mit berschriften, Zusammenfassungen und Textausschnitten der jeweils jüngsten Meldungen. Der Feedreader dreht in regelmäßigen Abständen seine Runden, holt diese Dateien und - wieder daheim - präsentiert die enthaltenen Informationen übersichtlich lesbar. Erst ein Klick auf eine Überschrift lädt den entsprechenden Originalartikel schließlich in den Webbrowser. Statt sich der Reizüberflutung auf Dutzenden, unterschiedlich gestylten Websites auszusetzen, genügt so ein Blick auf die systematisch geordneten Texteinträge im Fenster des Feedreaders, um zu entscheiden, welche Beiträge einer genaueren Betrachtung würdig sind und welche nicht. Diese Sammel-und-Zeige-Programme gibt es mittlerweile in vielen Geschmacksrichtungen und für nahezu jedes Betriebssystem (siehe "Feedreade"). Der Haken: Die Betreiber der Webangebote müssen den Dienst unterstützen und die nötigen RSS-Dateien zur Verfügung stellen. Da sich die meisten News-Magazine allerdings mit Bannerwerbung finanzieren, standen ihre Herausgeber dieser Verbreitung ihrer Texte bisher skeptisch gegenüber. Doch langsam denken viele um: Immerhin kann das System Besucher anlocken. Und nicht irgendwelche. Die Leser sind ausgesprochen interessiert und motiviert, da sie sich explizit für ein bestimmtes Angebot entschieden haben - und nicht zufällig oder unter Zeitdruck durch die einzelnen Seiten stolpern. Spätestens seit mit Yahoo einer der großen Anbieter seine aktuellen Meldungen als Newsfeed verbreitet, darf man davon ausgehen, dass etliche Mitbewerber folgen werden. So könnte die praktische Technologie in absehbarer Zeit zum nützlichen Alltagswerkzeug werden. Bis das soweit ist, übernehmen spezialisierte Dienste den Job des Mittlers zwischen den Welten: Unter NewsIsFree.com kann sich jeder User seine individuelle Auswahl an RSSFeeds zusammenstellen. Sollte das betreffende Internet-Angebot die Technik noch nicht unterstützen, wird einfach kurzerhand der notwendige Feed extern generiert - ob es dem Betreiber nun passt oder nicht. Der Service ist in der Basis-Version kostenlos. RSS steht für "Rich Site Summary". Doch zuletzt werden die drei Buchstaben häufiger als Akronym für "Really Simple Syndication" eingesetzt. Die Idee geht zurück auf das Jahr 1999, als das mittlerweile beinahe verblichene Unternehmen Netscape mit Hilfe dieses Verfahrens die Popularität seines Portals MyNetscape.com erhöhen wollte. Der Durchbruch kam mit der Verbreitung der Weblogs. Angeregt durch die Integration des RSS-Standards in das beliebte Blog-Tool Radio Userland, übernahmen die Hersteller anderer Publishing-Systeme schnell diese Strategie, und heute kommt kaum noch ein Online-Journal ohne eigenen Newsfeed aus - erkennbar am kleinen XML-Button auf der Startseite.
Die Neuigkeits-Ströme können mehr, als einen schnellen Überblick über frische Artikel zu verschaffen: Mit Hilfe kleiner, handlicher Skripte lassen sich die externen Inhalte problemlos in eigene Webseiten einbinden. Die Aktualisierung läuft dabei automatisch. Einmal integriert, kann man so seinen Besuchern, neben den eigenen, stets aktuelle Meldungen aus anderen Ecken des Netzes anbieten. Vor allem wissenschaftliche oder fachspezifische Portale nutzen das zunehmend. Unterschiedliche Entwicklerteams mit verschiedenen Zielrichtungen haben in den vergangenen Jahren unglücklicherweise für eine recht unübersichtliche Versionsvielfalt im RSS-Lager geführt. Will man auf Nummer sicher gehen, empfiehlt sich der angestaubte Standard 0.91. Zwar hat sich eine Gruppe von Programmierern aufgemacht, News-Syndication mit einem einheitlichen Format aufs nächste Level zu befördern. Doch einstweilen scheinen zunächst noch einige Glaubenskriege ausdiskutiert zu werden. Bislang herrscht noch nicht einmal Einigkeit über den Projektnamen. Davon gänzlich ungerührt schickt sich die RSS-Technologie an, mindestens einen Veteranen aus den Anfangstagen des Internets abzulösen: den Newsletter. In den zunehmend überquellenden Postfächern finden die elektronischen Rundmails sowieso kaum Beachtung, und wer regelmäßig seinen Feedreader im Auge behält, benötigt schlichtweg keine Benachrichtigungen per E-Mail. Ob künftig kommerzielle Websites die Möglichkeiten der News-Syndication nutzen und Hinweise auf fremde Seiten in ihr Angebot integrieren werden, darf bezweifelt werden. Man stelle sich folgendes Szenario in der Offline-Welt vor: Neben einem Artikel im gedruckten Spiegel findet sich ein Kasten mit den Hinweisen: Zu diesem Thema finden Sie im aktuellen Focus diesen Beitrag und im neuen Stern jenen. Unvorstellbar. Aber bei genauerer Betrachtung wahrscheinlich sogar vorteilhaft für alle Beteiligten. Im Web ist das technisch bereits ohne weiteres machbar. Allein der Wille fehlt. Bisher."

Abstract

NewsAgent for Libraries is one of the projects funded by the eLib programme in the UK. Following a brief historical account of the original ideas behind the project, describes the main stages in developing the project: which aims to create a user configurable electronic news and current awareness service for library and information professionals with a mixture of content streams, including metadata. Users' interests are specified by profiles which are then matched with incoming records so that users are alerted by electronic mail of items of potential interest. Examples of creating profiles and of some of the 'input feeds' in the project are given as well as an example of the use of the Dublic Core metadata format for describing resources covered in NewsAgent

Abstract

The provision of access to materials in special collections intersects the fields of cataloging and special collections librarianship, sharing characteristics and challenges with both. In order to reveal the changing expectations regarding special collections cataloging professionals, the author examined job notices for positions advertised in C&RL News from 1980 to 2000. Three related hypotheses were tested in this study: fixed-term appointments would become more common; published requirements for consideration would be more rigorous; and positions would offer less relative compensation than in the past. These hypotheses were demonstrated to be untrue. In a larger context, the results of this study can be extrapolated to suggest means of improving education and training for professionals in special collections cataloging, highlighting the skills and abilities future employing institutions will be seeking.

Abstract

This study investigates how privacy as an ethical concept exists in two languages: Mandarin Chinese and American English. The exploration relies on two genres of corpora from 10 years: social media posts and news articles, 2010-2019. A mixed-methods approach combining structural topic modeling (STM) and human interpretation were used to work with the data. Findings show various privacy-related topics across the two languages. Moreover, some of these different topics revealed fundamental incompatibilities for understanding privacy across these two languages. In other words, some of the variations of topics do not just reflect contextual differences; they reveal how the two languages value privacy in different ways that can relate back to the society's ethical tradition. This study is one of the first empirically grounded intercultural explorations of the concept of privacy. It has shown that natural language is promising to operationalize intercultural and comparative privacy research, and it provides an examination of the concept as it is understood in these two languages.

Abstract

The delivery of personalized news content depends on the ability to predict user interests. We evaluated different methods for acquiring user profiles based on declared and actual interest in various news topics and items. In an experiment, 36 students rated their interest in six news topics and in specific news items and read on 6 days standard, nonpersonalized editions and personalized (basic or adaptive) news editions. We measured subjective satisfaction with the editions and expressed preferences, along with objective measures, to infer actual interest in items. Users' declared interest in news topics did not strongly predict their actual interest in specific news items. Satisfaction with all news editions was high, but participants preferred the personalized editions. User interest was weakly correlated with reading duration, article length, and reading order. Different measures predicted interest in different news topics. Explicit measures predicted interest in relatively clearly defined topics such as sports, but were less appropriate for broader topics such as science and technology. Our results indicate that explicit and implicit methods should be combined to generate user profiles. We suggest that a personalized newspaper should contain both general information and personalized items, selected based on specific combinations of measures for each of the different news topics. Based on the findings, we present a general model to decide on the personalization of news content to generate personalized editions for readers.

Abstract

Comprehensiveness and consistency in newspaper indexing depend on the effectiveness of subject analysis of the news items. Discusses indexing skills required in order to identify indexable concepts. Describes practical aspects of conceptual analysis, crystalises criteria and methods for the indexing of news stories, and eludicates reasons form providing multiple subject-entries for certain news items. Suggests rules for news analysis and speedy and accurate allocation of subject headings, and illustrates the technique of dealing with complex and diversified news headings reported at intervals. As the headlines do not always indicate the real subject of a news story, the identification of indexable concepts can become arduous and cumbersome. Discusses the methods, skills and capability needed to tackle such problems

Abstract

Filtering, vetting, and verifying digital information is an area of core interest in information science. Online fake news is a specific type of digital misinformation that poses serious threats to democratic institutions, misguides the public, and can lead to radicalization and violence. Hence, fake news detection is an important problem for information science research. While there have been multiple attempts to identify fake news, most of such efforts have focused on a single modality (e.g., only text-based or only visual features). However, news articles are increasingly framed as multimodal news stories, and hence, in this work, we propose a multimodal approach combining text and visual analysis of online news stories to automatically detect fake news. Drawing on key theories of information processing and presentation, we identify multiple text and visual features that are associated with fake or credible news articles. We then perform a predictive analysis to detect features most strongly associated with fake news. Next, we combine these features in predictive models using multiple machine-learning techniques. The experimental results indicate that a multimodal approach outperforms single-modality approaches, allowing for better fake news detection.

Abstract

Previous studies of user-generated vocabularies (e.g., Golder & Huberman, 2006; Munk & Mork, 2007b; Yoon, 2009) have proposed that a primary source of tag agreement across users is due to wide-spread use of tags at the basic level of abstraction. However, an investigation of levels of abstraction in user-generated tagging vocabularies did not support this notion. This study analyzed approximately 8000 tags generated by 40 subjects. Analysis of 7617 tags assigned to 36 online resources representing four content categories (TOOL, FRUIT, CLOTHING, VEHICLE) and three resource genres (news article, blog, ecommerce) did not find statistically significant preferences in the assignment of tags at the superordinate, subordinate or basic levels of abstraction. Within the framework of Heidegger's (1953/1996) notion of handiness , observed variations in the preferred level of abstraction are both natural and phenomenological in that perception and understanding -- and thus the meaning of "things" -- arise out of the individual's contextualized experiences of engaging with objects. Operationalization of superordinate, subordinate and basic levels of abstraction using Heidegger's notion of handiness may be able to account for differences in the everyday experiences and activities of taggers, thereby leading to a better understanding of user-generated tagging vocabularies.
