    Abstract
    While the Web has grown significantly in recent years, some portions of the Web remain largely underdeveloped, as shown in a lack of high-quality content and functionality. An example is the Arabic Web, in which a lack of well-structured Web directories limits users' ability to browse for Arabic resources. In this research, we proposed an approach to building Web directories for the underdeveloped Web and developed a proof-of-concept prototype called the Arabic Medical Web Directory (AMedDir) that supports browsing of over 5,000 Arabic medical Web sites and pages organized in a hierarchical structure. We conducted an experiment involving Arab participants and found that the AMedDir significantly outperformed two benchmark Arabic Web directories in terms of browsing effectiveness, efficiency, information quality, and user satisfaction. Participants expressed strong preference for the AMedDir and provided many positive comments. This research thus contributes to developing a useful Web directory for organizing the information in the Arabic medical domain and to a better understanding of how to support browsing on the underdeveloped Web.

    Abstract
    We present a study to develop an improved understanding of symbolic links in web directories. A symbolic link is a hyperlink which makes a directed connection from a webpage along one path through a directory to a page along another path. While symbolic links are ubiquitous in web directories such as Yahoo!, they are under-studied and, as a result, their uses are poorly understood. A cursory analysis of symbolic links reveals multiple uses: to provide navigational shortcuts deeper into a directory, backlinks to more general categories, and multiclassification. We investigated these uses in the Open Directory Project (ODP), the largest, most comprehensive, and most widely distributed human-compiled taxonomy of links to websites, which makes extensive use of symbolic links. The results reveal that while symbolic links in ODP are used primarily for multiclassification, only few multiclassification links actually span top- and second-level categories. This indicates that most symbolic links in ODP are used to create multiclassification between topics which are nested more than two levels deep and suggests that there may be multiple uses of multiclassification links. We also situate symbolic links vis à vis other semantic and structural link types from hypermedia. We anticipate that the results and relationships identified and discussed in this paper will provide a foundation for (1) users for understanding the usages of symbolic links in a directory, (2) designers to employ symbolic links more effectively when building and maintaining directories and for crafting user interfaces to them, and (3) information retrieval researchers for further study of symbolic links in web directories.

    Abstract
    This study developed a specialized directory system using an automatic classification technique. Economics was selected as the subject field for the classification experiments with Web documents. The classification scheme of the directory follows the DDC, and subject terms representing each class number or subject category were selected from the DDC table to construct a representative term dictionary. In collecting and classifying the Web documents, various strategies were tested in order to find the optimal thresholds. In the classification experiments, Web documents in economics were classified into a total of 757 hierarchical subject categories built from the DDC scheme. The first and second experiments using the representative term dictionary resulted in relatively high precision ratios of 77 and 60%, respectively. The third experiment employing a machine learning-based k-nearest neighbours (kNN) classifier in a closed experimental setting achieved a precision ratio of 96%. This implies that it is possible to enhance the classification performance by applying a hybrid method combining a dictionary-based technique and a kNN classifier

    Abstract
    Surfing the World Wide Web used to be cool, dude, real cool. But things have gotten hot - so hot that finding something useful an the Web is no longer cool. It is suffocating Web searchers in the smoke and debris of mountain-sized lists of hits, decisions about which search engines they should use, whether they will get lost in the dizzying maze of a subject directory, use the right syntax for the search engine at hand, enter keywords that are likely to retrieve hits an the topics they have in mind, or enlist a browser that has sufficient functionality to display the most promising hits. When it comes to Web searching, in a few short years we have gone from the cool image of surfing the Web into the frying pan of searching the Web. We can turn down the heat by rethinking what Web searchers are doing and introduce some order into the chaos. Web search strategies that are tool-based-oriented to specific Web searching tools such as search en gines, subject directories, and meta search engines-have been widely promoted, and these strategies are just not working. It is time to dissect what Web searching tools expect from searchers and adjust our search strategies to these new tools. This discussion offers Web searchers help in the form of search strategies that are based an strategies that librarians have been using for a long time to search commercial information retrieval systems like Dialog, NEXIS, Wilsonline, FirstSearch, and Data-Star.

    Abstract
    Children are increasingly using the Web. Cognitive theory tells us that directory structures are especially suited for information retrieval by children; however, empirical results show that they prefer keyword searching. One of the reasons for these findings could be that the directory structures and terminology are created by grown-ups. Using a card-sorting method and an enveloping system, we simulated the structure of a directory. Our goal was to try to understand what browsable, hierarchical subject categories children create when suggested terms are supplied and they are free to add or delete terms. Twelve groups of four children each (fourth and fifth graders) participated in our exploratory study. The initial terminology presented to the children was based on names of categories used in popular directories, in the sections on Arts, Television, Music, Cinema, and Celebrities. The children were allowed to introduce additional cards and change the terms appearing on the 61 cards. Findings show that the different groups reached reasonable consensus; the majority of the category names used by existing directories were acceptable by them and only a small minority of the terms caused confusion. Our recommendation is to include children in the design process of directories, not only in designing the interface but also in designing the content structure as well.

    Abstract
    Webkataloge sind gemeinsam mit Suchmaschinen die entscheidenden Navigationshilfen im Internet-, ursprünglich als Hobby begonnene Webverzeichnisse haben sich zu großen Internetportalen wie Yahoo! oder Web.de entwickelt. Die Kataloge sind innerhalb weniger Jahre bis auf über zwei Millionen Einträge gewachsen; das Vorgehen bei der Erstellung ihrer Systematik und die Qualität der Erfassung der Websites sind von diesem rapiden Wachstum geprägt. Die Tatsache, dass die Webkataloge überwiegend von "Nicht-Dokumentaren" erstellt werden, ist ein weiterer entscheidender Punkt zum Verständnis der Katalogentwicklung in den USA und Deutschland. Dokumentarisches bzw. bibliothekarisches Know-how spielt nur eine Nebenrolle bei ihrer Entwicklung. Am deutlichsten wird dies beim nichtkommerziellen "Open Directory Project", das in den letzten drei Jahren den weltgrößten Webkatalog erarbeitet hat. Auf Grund der Konkurrenzsituation auf dem Portalmarkt und des hohen Personalaufwands für die Katalogerstellung hat in den USA eine Marktbereinigung auf nur noch drei große Webkatalog-Anbieter stattgefunden; diese Faktoren werden auch die Entwicklung der Kataloge im deutschsprachigen Raum beeinflussen. Ein guter Zeitpunkt, um eine Zwischenbilanz zu ziehen und über die Trends in diesem Bereich zu berichten

    Abstract
    Auch wenn Suchmaschinen wie Google ihre Ergebnis-Qualität in den letzten Jahren stark gesteigert haben, sind Webkataloge weiterhin eine wertvolle RechercheAlternativefür relevante Internet-Ressourcen. Während die meisten Webkataloge aufgrund des Fachwissens ihrerBearbeiter nur Websites zu einem Thema erschließen, existiert mit dem "Open Directory Project (ODP)" ein weltweiter Webkatalog, in dem bereits über 4,5 Millionen Websites erfasst sind. In der öffentlichen Wahrnehmung spielen Webkataloge kaum eine Rolle, was u.a. an der extremen Heterogenität (sowohl der Katalog-Bearbeiter als auch der Katalog-Qualität) liegt wie auch an der Notwendigkeit, zuerst den geeigneten Katalog selbst recherchieren zu müssen. Mit dem Wissen, wo und wie gute Kataloge zu finden sind, und unter welchen Maßgaben sie entstehen, können viele InternetRecherchen effektiver durchgeführt werden. Neben der Vorstellung exemplarischer Webkataloge werden praxisorientierte Strategien für die Website-Auswahl und -Beschreibung vorgestellt.

    Abstract
    This paper presents a comparative study of six French-language Web directories (MSN, Nomade, Open Directory, Voila, Voila Pages Perso, and Yahoo). The study focuses an the quantitative and qualitative aspects of the organization of these directories, and an the way in which they describe sites. It reveals a wide variety of structures, content and organizational principles. In this respect, Web directories do not correspond to classic theories of classification. They highlight the difficulty of proposing a structured representation of the heterogeneous content of the Web.

    Abstract
    Concerns about health issues cover a wide spectrum. Consumer health information, which has become more available on the Internet, plays an extremely important role in addressing these concerns. A subject directory as an information organization and browsing mechanism is widely used in consumer health-related Websites. In this study we employed the information visualization technique Self-Organizing Map (SOM) in combination with a new U-matrix algorithm to analyze health subject clusters through a Web transaction log. An experimental study was conducted to test the proposed methods. The findings show that the clusters identified from the same cells based on path-length-1 outperformed both the clusters from the adjacent cells based on path-length-1 and the clusters from the same cells based on path-length-2 in the visual SOM display. The U-matrix method successfully distinguished the irrelevant subjects situated in the adjacent cells with different colors in the SOM display. The findings of this study lead to a better understanding of the health-related subject relationship from the users' traversal perspective.
