    Abstract
    Examines the concept of hypertext and how it relates to the World Wide Web, along with a discussion of why this is important to librarians. Includes examples of library Web pages and products that take advantage of the medium and some that do not, along with a specific discussion of crafting text, structure and linking for the Web.

    Abstract
    The paradigm shift from the old system centered view to a user centered approach involves new tools needed for accessing library resources under the condition that the user's needs are taken into account. An end-user, who has only a little knowledge of classification systems or thesauri, understands little of the mode of the representation of contents and the use of authority lists. In addition, he will have difficulty in formulating his question in a precise manner. He needs to know better what the library proposes in order to define of what use it would be for him. Many studies have been carried out on the use of controlled vocabularies (classification, authority lists, thesauri) as searching devices. It is surprising to find that relatively little attention has been given to the role of these tools in filtering and browsing processes. We have developed a prototype named CATHIE (CATalog Hypertextuel Interactif et Enrichi) that supports such filtering and interactive reformulation features

    Natural language generation techniques can be used to dynamically produce hypertext dynamic catalogues on the Web, resulting in DYNAMIC HYPERTEXT. A dynamic hypertext document can be tailored more precisely to a particular user's needs and background, thus helping the user to search more effectively. Describes the automatic generation of WWW documents and illustrates with 2 implemented systems

    Abstract
    Richer graph models permit authors to 'program' the browsing behaviour they want WWW readers to see by turning the hypertext into a hyperprogram with specific semantics. Multiple browsing streams can be started under the author's control and then kept in step through the synchronization mechanisms provided by the graph model. Adds a Semantic Web Graph Layer (SWGL) which allows dynamic interpretation of link and node structures according to graph models. Details the SWGL and its architecture, some sample protocol implementations, and the latest extensions to MHTML

    Abstract
    We present a declarative language for the construction of hypertext views on databases. The language is based on an object-oriented data model and a simple hypertext model with reference and inclusion links. A hypertext view specification consists in a collection of parameterized node schemes which specify how to construct node and links instances from the database contents. We show how this language can express different issues in hypertext view design. These include: the direct mapping of objects to nodes; the construction of complex nodes based on sets of objects; the representation of polymorphic sets of objects; and the representation of tree and graph structures. We have defined sublanguages corresponding to particular database models (relational, semantic, object-oriented) and implemented tools to generate Web views for these database models

    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
    A materialized hypertext view is a hypertext containing data coming from a database and whose pages are stored in files. A Web site presenting data coming from a database is an example of such a view, where the hypertext pages are HTML files. Even if the most popular approach to the generation of such sites is the virtual one, there is also a rationale for a materialized apporach. This paper deals with the maintenance issues required by these derived hypertext to enforce consistency between page content and database state

    Abstract
    The World Wide Web (WWW) is one of the newest tools available to assist in the navigation of the Internet. As with other client/server network tools such as Gopher and WAIS, developments with the Web are in a dynamic state of change. Basically, WWW is an effort to organize information on the Internet plus local information into a set of hypertext documents; a person navigates the network by moving from one document to another via a set of hypertext links

    Abstract
    The OtaOnline project at the Helsinki University of Technology, Finland, has been deploying the distribution of Finnish newspapers such as Iltalehti, Aamulehti and Kauppalehi on the Internet since 1994. The editors produce the electronic counterpart of these papers by a conversion process from QuarkXpress documents to HTML. The project is about to introduce an approach which provides many new features. Describes an object-oriented approach which implements the logical model of a hypermedia newspaper. It encapsulates the structures of the hypermedia documents as well as their capability for transforming into different presentation formats. It also provides a semantical rating mechanism to be used with intelligent agents. Presents a distribution scheme which enables efficient use of this model

    Rez. in: nfd 54(2003) H.8, S.497 (T. Mandl): "Gesetze der digitalen Anarchie - Hyperlinks im Internet entstehen als Ergebnis sozialer Prozesse und können auch als formaler Graph im Sinne der Mathematik interpretiert werden. Die Thematik Hyperlinks ist im Information Retrieval höchst aktuell, da Suchmaschinen die Link-Struktur bei der Berechnung ihrer Ergebnisse berücksichtigen. Algorithmen zur Bestimmung des "guten Rufs" einer Seite wie etwa PageRank von Google gewichten eine Seite höher, wenn viele links auf sie verweisen. Barabási erklärt dem Leser seines Buches darüber hinaus noch, wie es zu solchen Phänomenen kommt. Soziale Prozesse im Netz wirken so, dass bereits bekannte Seiten mit größerer Wahrscheinlichkeit auch wieder weitere Links oder neue Besucher anziehen. Barabási ist Physiker an der Notre-Dame University und ihm fehlt ebenso wie Huberman die informationswissenschaftliche Perspektive. Er fragt also kaum, wie kann das Wissen über Netzwerke zu Verbesserungen in Informationssystemen führen, die Benutzerbedürfnisse besser erfüllen. Gleichwohl lohnt sich die Lektüre auch für Informationswissenschaftler. Barabäsi stellt die aktuelle Forschung zur Netzwerkstruktur des Internets auf einfache Weise fast ohne Zugeständnisse an Aktualität und Komplexität dar. Wie Huberman verzichtet auch er weitgehend auf Formeln und andere Formalismen. Der in Ungarn geborene Barabási lässt darüber hinaus keine Anekdote aus, sei es über die Begründer der Graphen-Theorie, im peer-review abgelehnte Beiträge und persönliche Begegnungen mit anderen Forschern. Barabási beginnt mit einfachen Netzwerkstrukturen und schreitet didaktisch über internet-ähnliche Netzwerke weiter zu Anwendungen und praktischen Beispielen aus unterschiedlichsten Disziplinen. Er schafft mit seinem Buch "Linked" unter anderem Links zwischen der ungarischen Literatur, dem I-Love-You Computer-Virus, der Verbreitung von Aids, den Theorien Einsteins, den Aufsichtsräten der wichtigsten amerikanischen Firmen, dem Al-Qaeda-Netzwerk und der Struktur und der Funktion biologischer Zellen. Zu Beginn seines Buches berichtet Barabási von sogenannten kleinen Welten, in denen viele Objekte über wenige Verbindungen zusammenhängen. Ein Blick in den eigenen größeren Bekanntenkreis mag bestätigen, dass viele Menschen über wenige Schritte zwischen Bekannten erreichbar sind. Sowohl Barabäsi als auch Huberman gehen auf die Geschichte des ersten sozialwissenschaftlichen Experiments zu diesem Thema ein, das in den 1960er Jahren versuchte, die Anzahl von Schritten zwischen gemeinsamen Bekannten zu bestimmen, welche vom Mittleren Westen der USA an die Ostküste führt. Die genauere Struktur solcher Systeme, in denen manche Knoten weitaus mehr Beziehungen zu anderen eingehen als der Durchschnitt, führt hin zum Internet. Im Web lässt sich keineswegs immer ein Pfad zwischen zwei Knoten finden, wie noch vor wenigen Jahren vermutet wurde. Die durchschnittliche Entfernung war damals noch mit 19 Klicks berechnet worden. Vielmehr herrscht eine differenziertere Struktur, die Barabási vorstellt und in der zahlreiche Seiten in Sackgassen führen. Huberman wie Barabási diskutieren auch negative Aspekte des Internet. Während Huberman die Wartezeiten und Staus bei Downloads analysiert, bespricht Barabási die rasante Verbreitung von ComputerViren und weist auf die Grundlagen für diese Gefährdung hin. Das vorletzte Kapitel widmen übrigens beide Autoren den Märkten im Internet. Spätestens hier werden die wirtschaftlichen Aspekte von Netzwerken deutlich. Beide Titel führen den Leser in die neue Forschung zur Struktur des Internet als Netzwerk und sind leicht lesbar. Beides sind wissenschaftliche Bücher, wenden sich aber auch an den interessierten Laien. Das Buch von Barabási ist etwas aktueller, plauderhafter, länger, umfassender und etwas populärwissenschaftlicher."
