    Footnote
    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."

    Abstract
    Most existing hypermedia authoring systems incorporate facilities for the creation of static links between pieces of information, termed nodes. Such links usually support only browsing activities over the hypermedia web, carrying little or no information about the conceptual relationship the nodes might have. Thus indecision occurs: the reader of the hypermedia can traverse a link but has no indication what link to choose and what he might expect from the traversal. At the same time, the creation of these links requires a great effort from the author, moreover if there are certain criteria that guide linking. This paper presents a two-layered hypermedia semantic model that enriches the semantic links, and alsoprovides the means for dynamic link creation. To accomplish these objectives, we adopt the use of fuzzy set theory and fuzzy logic as the mathematical framework for link characterization and dynamic link creation. Some aspects of a prototype system, named Platon, are also presented

    Abstract
    The C(K)onstance Hypertext system (KHS) is an elaborated example of an open hypertext system. Open hypertext systems combine heterogeneous resources and different hypertext applications such as email, text and image hypertexts with access to online data bases or other information resources. These hypertexts, to which heterogeneous users have access, grow steadily in size. This paper takes an object-oriented approach and proposes a rigorous typing of hypertext objexts to overcome the problems of open hypertext. The advantage of this typing is shown an an e-mail hypertext as a special application of the KHS system. KHS is written in Smalltalk and is being developed an UNIX-machines.

    Abstract
    Proposes a conceptual model to examine hypertext information presentation effects on decision making performance when compared with traditional sequentional information presentation and access. Considers which combination of task knowledge type (superficial, and causal) and information presentation styles (sequential, hypertext) yield the best decision making performance. This is achieved by comparing performance effect of hypertext and sequential information presentation when applied to superficial and causal type of knowledge required for the task. The 2 surrogates used for measuring the outcome of the performance effects are decision time and secision accuracy

    Abstract
    This article examines searcher behavior and affective response to a hypertext-based bibliographic information retrieval system called HyperLynx for searchers with different search skills and backgrounds. Search times and number of nodes visited were recorded for five specified search queries, and views of the system were recorded for each searcher. No significant differences were found in search times or user satisfaction with the system, indicating that a hypertext-based approach to bibliographic retrieval could be appropriate for a variety of searcher experience levels

    Abstract
    Analyzes an abstract model for hypermedia pplications. The model, Labyrinth, allows: the design of platform-independent hypermedia applications; the categorisation, generalisation and abstraction of unstructured heterogeneous information in multiple and interconnected levels, the creation of personalisations in multiuser hyperdocuments for both groups and individual users and the design of advanced security mechanisms for hypermedia applications

    Abstract
    In a hypertext database, the information is presented as a network of nodes connected by links. Such nodes may be text, graphics, audio, video, and even other software. Although hypertext provides a new approach to information management, it also leaves a whole new set of problems for the designers of the hypertext database to solve. As the volume of information grows, the task of authoring a hypertext database becomes much more complex. In this article, the author presents the experiences during the development of a hypertext version of the user's guide for information services on JANET, in the UK, by using HyperPAD, a hypertext shell for the IBM PC. It may be the first step to explore the proper way to solve those problems which come together with the increasing application of hypertext

    Abstract
    Part of a special issue on hypertext and information retrieval. Conventional information retrieval systems provide little support for browsing. Browsing is the major method of searching in hypertext system but users can become disoriented even when browsing small information space. If hypertext is to be used to support browsing in bibliographic databases navigational assistance will be required. Examines the role of thesauri as navigational aids for subject domains of Bibliographic databases. Presents the design of an experimental hypertext-based browsing inference for a thesaurus and its implementation using a commercially available hypertext program. Examines strategies for linking the thesaurus to a database
