Abstract

Google News and other newsbots have automated the process of news selection, providing Internet users with a virtually limitless array of news and public information dynamically culled from thousands of news organizations all over the world. In order to help users cope with the resultant overload of information, news leads are typically accompanied by three cues: (a) the name of the primary source from which the headline and lead were borrowed, (b) the time elapsed since the story broke, and (c) the number of related articles written about this story by other news organizations tracked by the newsbot. This article investigates the psychological significance of these cues by positing that the information scent transmitted by each cue triggers a distinct heuristic (mental shortcut) that tends to influence online users' perceptions of a given news item, with implications for their assessment of the item's relevance to their information needs and interests. A large 2 x 3 x 6 withinsubjects online experiment (N = 523) systematically varied two levels of the source credibility cue, three levels of the upload recency cue and six levels of the number-ofrelated-articles cue in an effort to investigate their effects upon perceived message credibility, newsworthiness, and likelihood of clicking on the news lead. Results showed evidence for source primacy effect, and some indication of a cue-cumulation effect when source credibility is low. Findings are discussed in the context of machine and bandwagon heuristics.

Abstract

News is information about recent events of general interest, especially as currently reportes by newspapers, periodicals, radio or television. News is the quintessential multimedia data. While newspaper editors (human and/or algorithmic) may still define the core content of electronic news, new communication technologies will enable the integration of news from a wide variety of sources and provide access to supplemental material from enormous archives of electronic news data (text, photos, and video) in digital libraries as well as the continual streams of newly created data. The goal of electronic news delivery within this context is, however, distiguishable from both news news groups and document retrieval. Electronic news promises to deliver to the reader an edited collage of recent events from wide domains in a manner that is both comprehensive and personalized. As part of a long-term research project into the design of future news delivery systems, we have developed an overall architecture and several prototypes. These prototypes are presented in the article, along with a discussion of issues related to the presentation metaphor and to the functionality of electronic news delivery services. A prototype was demonstrated at the 1995 G-7 Economic Summit in Halifax, Canada, integrating newspaper text and photographs with television news video clips across an ATM network

Content

"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

Mit erfundenen Meldungen lässt sich im Internet viel Geld und politisch Stimmung machen. Wie kann man sie erkennen? Ein Beitrag zum Thema Fake News. Fazit: "Ein Rezept, mit dem man Fake News erkennt, gibt es noch nicht. Bader und Rinsdorf sind aber auf der Suche danach. Im Moment analysieren sie Tausende Fake News auf auffällige Textmerkmale. Anschließend sollen Algorithmen programmiert werden, die in Sekundenschnelle erkennen, mit welcher Wahrscheinlichkeit es sich um eine gefälschte Nachricht handelt. Bader und Rinsdorf: "Wer die Nachrichtenvielfalt nutzt, sich breit informiert und Informationen im Netz mit einer gewissen Grundskepsis begegnet, kann Fake News schneller durchschauen.""

Abstract

Although the Internet has become a major source for accessing news, there is little research regarding users' experience with news sites. We conducted an experiment to test a comprehensive model of user experience with news sites that was developed previously by means of an online survey. Level of adoption (novel or adopted site) was controlled with a between-subjects manipulation. We collected participants' answers to psychometric scales at 2 times: after presentation of 5 screenshots of a news site and directly after 10 minutes of hands-on experience with the site. The model was extended with the prediction of users' satisfaction with news sites as a high-level design goal. A psychometric measure of trust in news providers was developed and added to the model to better predict people's intention to use particular news sites. The model presented in this article represents a theoretically founded, empirically tested basis for evaluating news websites, and it holds theoretical relevance to user-experience research in general. Finally, the findings and the model are applied to provide practical guidance in design prioritization.

Abstract

Examines the problem of a compelling online news delivery system by focusing on how mass media audiences and online users differ in their assessment of news. It employed a 2-wave USA national survey to study the perception of interactivity in mass media and computer networks and its relationship to the assessment of news. The 1st wave looked a national probability sample, ahile the 2nd targeted viewers of NBC Nightly News who responded to the show via e-mail. NBC respondents rated mass media to be less interactive, while they rated computer communication more interactive than the national sample. The NBC group also rated mass media news less important and of lower quality than did the national sample. Interactivity ratings did not predict mass media credibility assessment for either group. However, respondents who defined interactivity as cybernetic feedback or who contacted NBC by e-mail rated computer communication to be more credible than thos who did not

Abstract

Electronic news has long held the promise of personalized and dynamic delivery of current event new items, particularly for Web users. Although wlwctronic versions of print news are now widely available, the personalization of that delivery has not yet been accomplished. In this paper, we present a methodology of associating news documents based on the extraction of feature phrases, where feature phrases identify dates, locations, people and organizations. A news representation is created from these feature phrases to define news objects that can then be compared and ranked to find related news items. Unlike tradtional information retrieval, we are much more interested in precision than recall. That is, the user would like to see one or more specifically related articles, rather than all somewhat related articles. The algorithm is designed to work interactively the the user using regular web browsers as the interface

Abstract

As the Web has become a major channel of information dissemination, many newspapers expand their services by providing electronic versions of news information on the Web. However, most investors find it difficult to search for the financial information of interest from the huge Web information space-information overloading problem. In this article, we present a personal agent that utilizes user profiles and user relevance feedback to search for the Chinese Web financial news articles on behalf of users. A Chinese indexing component is developed to index the continuously fetched Chinese financial news articles. User profiles capture the basic knowledge of user preferences based on the sources of news articles, the regions of the news reported, categories of industries related, the listed companies, and user-specified keywords. User feedback captures the semantics of the user rated news articles. The search engine ranks the top 20 news articles that users are most interested in and report to the user daily or on demand. Experiments are conducted to measure the performance of the agents based on the inputs from user profiles and user feedback. It shows that simply using the user profiles does not increase the precision of the retrieval. However, user relevance feedback helps to increase the performance of the retrieval as the user interact with the system until it reaches the optimal performance. Combining both user profiles and user relevance feedback produces the best performance

Abstract

We study the news reading behavior of several hundred thousand users on 65 highly visited news sites. We focus on a specific phenomenon: users reading several articles related to a particular news development, which we call story-focused reading. Our goal is to understand the effect of story-focused reading on user engagement and how news sites can support this phenomenon. We found that most users focus on stories that interest them and that even casual news readers engage in story-focused reading. During story-focused reading, users spend more time reading and a larger number of news sites are involved. In addition, readers employ different strategies to find articles related to a story. We also analyze how news sites promote story-focused reading by looking at how they link their articles to related content published by them, or by other sources. The results show that providing links to related content leads to a higher engagement of the users, and that this is the case even for links to external sites. We also show that the performance of links can be affected by their type, their position, and how many of them are present within an article.

Abstract

Most on-line news sources are electronic versions of "ink-on-paper" newspapers. These are versions that have been filtered, from the mass of news produced each day, by an editorial board with a given community profile in mind. As readers, we choose the filter rather than choose the stories. New technology, however, provides the potential for personalized versions to be filtered automatically from this mass of news on the basis of user profiles. People read the news for many reasons: to find out "what's going on," to be knowledgeable members of a community, and because the activity itself is pleasurable. Given this, we ask the question, "How much filtering is acceptable to readers?" In this study, an evaluation of user preference for personal editions versus community editions of on-line news was performed. A personalized edition of a local newspaper was created for each subject based on an elliptical model that combined the user profile and community profile as represented by the full edition of the local newspaper. The amount of emphasis given the user profile and the community profile was varied to test the subjects' reactions to different amounts of personalized filtering. The task was simply, "read the news," rather than any subject specific information retrieval task. The results indicate that users prefer the coarse-grained community filters to fine-grained personalized filters

Abstract

Virtually all UK and US newspapers and the vast majority of regional and even local titles are now represented on the web. Indeed, the Yahoo news and media directory lists no less than 114 UK newspapers online (as of November 1998). Broadcasters from the BBC and Sky downwards, and all the famous news agencies (Press Association, Reuters etc.) also boast comprehensive Internet services. With such an array of sources available, the future of mass access to the Internet, possibly via TV terminals, suggests that more and more people may soon opt for this medium to receive the bulk of their news information. This paper gives an overview of the characteristics of the medium illustrated with examples of how these are being used to both facilitate and enhance the content and dissemination of the news product. These characteristics include hyperlinking to external information sources, providing archive access to past reports, reader interactivity and other features not possible to incorporate into more passive media such as the hardcopy newspaper. From a survey of UK and US news providers it is clear that American newspapers are exploiting the advantages of web information dissemination to a far greater extent than their British counterparts, with the notable exception of The Electronic Telegraph. UK broadcasters, however, generally appear to have adapted better to the new medium, with the BBC rivaling CNN in its depth and extent of news coverage, use of links and other elements.
