    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
    Information technology (IT) encompassing an integrated library system, computer hardware and software, CDROM, Internet, and other domains, including MARC 21 formats, CORC, and metadata standards (Dublin Core, TEI, XML, RDF) has produced far-reaching changes in the job functions of catalogers. Libraries are now coming up with a new set of recruiting requirements for these positions. This paper aims to review job advertisements published in American Libraries (AL) and College and Research Libraries News (C&RL NEWS) to assess the impact of the use of IT in libraries an job requirements and qualifications for catalogers.

    Abstract
    This is the era of social networking, collective intelligence, participation, collaborative creation, and borderless distribution. Every day we are bombarded with more publicity about collaborative environments, news feeds, blogs, wikis, podcasting, webcasting, folksonomies, social bookmarking, social citations, collaborative filtering, recommender systems, media sharing, massive multiplayer online games, virtual worlds, and mash-ups. This sort of anarchic environment appeals to the digital natives, but which of these so-called 'Web 2.0' technologies are going to have a real business impact? This paper addresses the impact that issues such as quality control, security, privacy and bandwidth may have on the implementation of social networking in hide-bound, large organizations.

    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
    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
    Purpose - The purpose of this research is to develop a method for automatic construction of multi-document summaries of sets of news articles that might be retrieved by a web search engine in response to a user query. Design/methodology/approach - Based on the cross-document discourse analysis, an event-based framework is proposed for integrating and organizing information extracted from different news articles. It has a hierarchical structure in which the summarized information is presented at the top level and more detailed information given at the lower levels. A tree-view interface was implemented for displaying a multi-document summary based on the framework. A preliminary user evaluation was performed by comparing the framework-based summaries against the sentence-based summaries. Findings - In a small evaluation, all the human subjects preferred the framework-based summaries to the sentence-based summaries. It indicates that the event-based framework is an effective way to summarize a set of news articles reporting an event or a series of relevant events. Research limitations/implications - Limited to event-based news articles only, not applicable to news critiques and other kinds of news articles. A summarization system based on the event-based framework is being implemented. Practical implications - Multi-document summarization of news articles can adopt the proposed event-based framework. Originality/value - An event-based framework for summarizing sets of news articles was developed and evaluated using a tree-view interface for displaying such summaries.

    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
    Themenentdeckung und -verfolgung (topic detection and tracking; TDT) fasst unterschiedliche Dokumente zu einem Thema zusammen und bietet dem Nutzer zunächst das Thema und erst in einem zweiten Schritt die einzelnen Dokumente zur Anzeige an. TDT ist nützlich bei Nachrichten sowie bei Blog-Einträgen. Ein bekanntes Beispiel ist Google News. Der Artikel bespricht den Forschungsstand zu TDT und diskutiert den Einsatz von TDT bei News-Informationsdiensten wie z.B. Factiva oder LexisNexis. Dort ist TDT zweifach wichtig: Erstens ist es (analog zu Google News) bei Profildiensten einsetzbar, zweitens ist es möglich, Dokumente zum gleichen Thema in einen Ordner zu klassieren, um bei einer retrospektiven Recherche die Treffermenge geordnet nach unterschiedlichen Themen anzubieten (und dies ohne Nutzung einer Dokumentationssprache).
