    Abstract
    Online discussion forums have become a popular medium for users to discuss with and seek information from other users having similar interests. A typical discussion thread consists of a sequence of posts posted by multiple users. Each post in a thread serves a different purpose providing different types of information and, thus, may not be equally useful for all applications. Identifying the purpose and nature of each post in a discussion thread is thus an interesting research problem as it can help in improving information extraction and intelligent assistance techniques. We study the problem of classifying a given post as per its purpose in the discussion thread and employ features based on the post's content, structure of the thread, behavior of the participating users, and sentiment analysis of the post's content. We evaluate our approach on two forum data sets belonging to different genres and achieve strong classification performance. We also analyze the relative importance of different features used for the post classification task. Next, as a use case, we describe how the post class information can help in thread retrieval by incorporating this information in a state-of-the-art thread retrieval model.

    Abstract
    Language barrier is the major problem that people face in searching for, retrieving, and understanding multilingual collections on the Internet. This paper deals with query translation and document translation in a Chinese-English information retrieval system called MTIR. Bilingual dictionary and monolingual corpus-based approaches are adopted to select suitable tranlated query terms. A machine transliteration algorithm is introduced to resolve proper name searching. We consider several design issues for document translation, including which material is translated, what roles the HTML tags play in translation, what the tradeoff is between the speed performance and the translation performance, and what from the translated result is presented in. About 100.000 Web pages translated in the last 4 months of 1997 are used for quantitative study of online and real-time Web page translation

    "Bin gestern im MoMA gewesen. Hab dann noch mal in der Tate vorbeigeschaut. Nachher dann noch einen Abstecher in die Alte Nationalgalerie gemacht. New York, London, Berlin an einem Tag, das ist dank Google kein Problem mehr. Auf der Plattform www.googleartproject.com bietet der Netz-Gigant jetzt einige virtuelle Museumsrundgänge durch einige der bekanntesten und bedeutendsten Häuser der Welt an. Googles neuestes Angebot unterscheidet sich von den in der Regel gut aufgestellten Homepages der Museen vor allem durch die Street-View-Technologie, mit der man von Raum zu Raum und von Bild zu Bild wandeln kann. Dazu hat der Besucher die Möglichkeit, zahlreiche Informationen zu den Kunstwerken abzurufen, oder die Werke in hochauflösenden Vergrößerungen anzuschauen. Aus jeder der teilnehmenden 17 Sammlungen hat Google ein Werk in einer Auflösung von sieben Milliarden Pixeln fotografiert. Wenn man da beim Rundgang durch die Alte Nationalgalerie auf Edouard Manets "Dans la Serre" (Im Wintergarten) trifft und nur einmal den Fingerring des Mannes heranzoomt, wird er gleichsam zur Unkenntlichkeit vergrößert, und man sieht wie unter einem Mikroskop jedes kleinste Detail des Farbauftrags, jeden feinsten Riss. Faszinierend. Auch wenn es das Original nicht ersetzt."

    Abstract
    Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.

    Abstract
    In this paper, we report on the second part of an empirical study designed to observe how users interact with World Wide Web resources. Applying a holistic approach, the researches examine users' cognitive, affective, and physical behaviors during user-Web interaction in order to understand better the nature of information retrieval on the Web, the needs of Web users, and the problem-solving strategies Web users employ. From analyses and the participant verbalizations collected during monitored searches, the researchers developed a taxonomy of problem solving strategies. The coding scheme was developed based on a content analysis of the integrated process data. Information from triangulation follow-up with participants via anonymously completed questionnaires, the taxonomy, and analyses of search transcripts were collected to determine 1) what problems users encountered during the interaction and how users solved these problems; and 2) which problem-solving strategies Web users considered and selected for finding factual information. The focus of the coding was on the participants' cognitive, affective, and physical behaviors in response to the components of the problems encountered, which included problems of the following types: Web interfaces, users' mental models, and the Web information sources. Searching behavior and problem-solving patterns are described and interpreted within the relevant situational context and the problems users encountered are identified and analyzed. Both the problems users faced and their problem-solving approaches endeavored evidence a strong reliance on mental models of the features available on sites, the location of those features, and other interface design concepts

    Abstract
    Die Hyperlinktechnologie des WWW wird von immer mehr bibliographischen Datenbanken genützt, um eine schnelle und umfassende Information und vor allem einen unmittelbaren Zugang zu den Informationsdokumenten wie Aufsätzen, Reports usw. anzubieten. Die Rechercheergebnisse einer webbasierten Datenbank sind dementsprechend oft mit einer ganzen Reihe von Hyperlinks ausgestattet. So gibt es in vielen Datenbanken Hyperlinks, die zu den Standortnachweisen von Zeitschriften in einem Verbundkatalog oder evtl. zur elektronischen Version einer Zeitschrift, d.h. zu deren Homepage, hinführen. In manchen Datenbanken führen Hyperlinks auch unmittelbar zum Volltext des einzelnen Artikels hin. Bei dieser mit dem englischen Fachausdruck Reference Linking bezeichneten bibliographischen Verknüpfungstechnik entsteht das Problem, wie ein auf einer Webseite zitierter oder von einer Datenbank als Treffer angezeigter Aufsatz so mit einer URL verbunden werden kann, dass als Ziel des Hyperlinks z.B. die entsprechende elektronische Version angesteuert oder der Bestandsnachweis der angegebenen Zeitschrift in einem Online-Katalog ermittelt wird. Eine akzeptable Lösung des Problems wäre eine standardisierte und frei zugängliche Art der URL-Adresse, ein sogen. OpenURL, der universell einsetzbar ist. Datenbanken, in denen diese Verknüpfungen bereits integriert sind, verwenden vielfach den DOI oder andere Metadaten in ihren Hyperlinkadressen. Der wesentliche Unterschied zwischen DOI und OpenURL besteht darin, dass die Daten für den DOI intern von den Datenbankanbietern vergeben werden, während die Daten für den OpenURL aus jedem einfachen Zitat genommen werden können. Daher ist der OpenURL leicht verwendbar und verknüpfbar, während die Verwendung des DOI in Verknüpfungssystemen davon abhängig ist, ob in dem Originaldokument bzw. der originalen Trefferanzeige ein solcher DOI auch angezeigt wird, was nicht immer der Fall ist. Selbst wenn in kommerziellen Datenbanken eine Verknüpfung mit elektronischen Zeitschriften integriert ist, zeigen diese meist keine Limitierung auf einen lokal verfügbaren Bestand an, so dass eine etwa vorhandene Zugänglichkeit auf Grund einer Subskription nicht erkennbar ist und die Verknüpfung oft ins Leere geht. Zudem führt ein Hyperlink oft nur dann auf den für eine Bibliothek verfügbaren Volltext, wenn die betreffende Zeitschrift beim Datenbankanbieter registriert ist. Die Linksysteme des Multisuchsystems E-Connect sind so konzipiert, dass sie durch ein vorangehendes Suchverfahren in einer Bestandsliste einen tatsächlichen (nicht bloß potentiellen!) Verfügbarkeitsnachweis für eine bestimmte Bibliothek herstellen. Dadurch ist sofort ein Überblick über evtl. zugängliche Volltexte vorhanden. Durch ein speziell von mir entwickeltes Verknüpfungsverfahren über die OpenURLs bzw. die Suchsysteme der Verlage und Gesellschaften ist außerdem der direkte Zugang zum Volltext möglich, unabhängig von einer etwaigen Registrierung und unabhängig davon, ob überhaupt in der Datenbank eine Verbindung zur betreffenden Zeitschrift besteht. Von dem Zugang zum Volltext abgesehen ist außerdem eine Verbindung eines angezeigten Treffers mit Verbundkatalogen wünschenswert, was von Datenbanken bisher nur wenig, von diesen Linksystemen aber durchweg realisiert wird. Das ist insofern wichtig, als es für viele Zeitschriften entweder überhaupt keine E-Version gibt oder keine Subskription vorliegt, so dass man auf die Printversion zurückgreifen muß. Bei einer Verbindung zum OPAC besteht außerdem auch vielfach die Möglichkeit einer Online-Bestellung, wodurch das Bestellverfahren beschleunigt und vereinfacht wird.

    Abstract
    The Internet now provides access to so much information that it is a problem to know what is available and how to navigate through it. The Wide Area Information Server (WAIS) is one project aiming to help solve the problem for the end user, by means of a graphical user inferface and the use of natural language for queries, which is then translated into the WAIS protocol. Describes how WAIS was developed, how it works, and difficulties with the project

    Abstract
    The Internet refers to more than 50.000 backbone regional and local computer networks in more than 50 countries with an estimated user base of over 3 million people. Finding out who has what available on the Internet has become a real problem since the network is expanding so quickly. Describes Archie (the McGill School of Computer Science Archive Server Listing Service), a tool which was developed to help solve this problem. Also describes Gopher, a distributed networking and document delivery system designed to access electronic information and navigate the Internet
