    Abstract
    Citation analysis has long been used by librarians as an important tool of collection development and the advent of Internet technology and especially the WWW adds a new facet to the role played by citation analysis. One of the reasons why librarians create WWW homepages is to provide users with further sources of interest or reference and to do this libraries include links from their own homepages to other information sources. Reports current research on the analysis of WWW pages as an introduction to an examination of the homepages of 25 art libraries to determine what sites are most often included. The types of linked sites are analyzed based on 3 criteria: location, focus and evidence that the link was evaluated before the connection was establisheds

    Abstract
    Homepages usually describe important semantic information about conceptual or physical entities; hence, they are the main targets for searching and browsing. To facilitate semantic-based information retrieval (IR) at a Web site, homepages can be identified and classified under some predefined concepts and these concepts are then used in query or browsing criteria, e.g., finding professor homepages containing information retrieval. In some Web sites, relationships may also exist among homepages. These relationship instances (also known as homepage relationships) enrich our knowledge about these Web sites and allow more expressive semantic-based IR. In this article, we investigate the features to be used in mining homepage relationships. We systematically develop different classes of inter-homepage features, namely, navigation, relative-location, and common-item features. We also propose deriving for each homepage a set of support pages to obtain richer and more complete content about the entity described by the homepage. The homepage together with its support pages are known to be a Web unit. By extracting inter-homepage features from Web units, our experiments on the WebKB dataset show that better homepage relationship mining accuracies can be achieved.

    Abstract
    Presents Dynamic Reference Sifting - a novel architecture that attempts to provide both maximally comprehensive coverage and highly precise responses in real time, for specific home page categories. Describes Ahoy! The Homepage Finder (http://www.cs.washington.edu/research/ahoy), a fielded Web service that embodies Dynamic Reference Sifting for the domain of personal homepages. Ahoy! filters the output of mulptile Web indices to extract 1 or 2 references that are most likely to point to the person's homepage. If it finds no likely candidates, Ahoy! uses knowledge of homepage placement conventions, which it has accumulated from previous experience, to guess the URL for the desired homepage. Ahoy! finds the target homepage and ranks it as the top reference. 9% of the targets are found by guessing the URL. altaVista can find 58% of the targets and ranks only 23% of these as the top reference

    Content
    "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
    Selten wurde ein Dienst so stark diskutiert wie 'RealNames', da sowohl seine Suchwörter als auch die darauf aufsetzenden Links auf Homepages verkauft werden. Machen wir uns doch nichts vor: Das WWW ist ein kommerzielles Unternehmen, die Dienstleistungen müssen finanziert werden. Und warum soll nicht ein Privatunternehmen mit Inhaltserschließung Gewinne erzielen? RealNames mit seinem 'Internet Keyword System' ist eine interessante Idee, das Retrieval nach Homepages zielgenau durchzuführen. Was bringt RealNames den Nutzern? Wann sollte jemand, der Sites im WWW unterhält, Suchwörter und Links bei RealNames abonnieren (und was kostet das)? Im Oktober 1999 haben wir RealNames genauer angeschaut. Analysiert wurde das gezielte Retrieval nach Homepages bei AltaVista, Fireball und bei RealNames.com

Diesen Fragen stellten sich insgesamt 22 Bibliothekarinnen und Bibliothekare in Münster und Köln während zweier Fortbildungsveranstaltungen des HBZ im Juni 2003. Ziel der jeweils zweitägigen Workshops, die in Zusammenarbeit mit der Adhoc-Arbeitsgruppe "Informationskompetenz" der AG der Universitätsbibliotheken im VBNW konzipiert wurden, waren Konzepte und erste Schritte zur Umsetzung von elektronischen Angeboten zur Vermittlung von Bibliotheksbzw. Informationskompetenz. Dem voraus ging die konstruktive Bewertung von bereits existierenden Materialien, die zum einen von den Teilnehmern aus ihren Bibliotheken mitgebracht wurden, zum anderen über Bibliotheks-Homepages abrufbar waren. Die Teilnehmer, die in ihren Bibliotheken bereits Benutzerschulungen konzipieren und durchführen, beschäftigten sich dabei in Gruppen u.a. mit den Themen - Virtuelle Rundgänge, - Online-Tutorials - Bibliothekseinführungen für Schüler und Erstsemester - Präsentationen von Online-Katalog und Methoden zur Literatursuche. Im Folgenden werden einige wesentliche und manchmal durchaus kontrovers diskutierte Ergebnisse und Thesen wiedergegeben, die sich aus der Arbeit der Teilnehmer ergeben haben. Sie erheben keinen Anspruch auf Ausgewogenheit oder Vollständigkeit, können aber als Anregungen und Diskussionsgrundlage für zukünftige Projekte dienen.

    Abstract
    This article compares the indexing structure of icons with principles used for traditional indexing. The investigators apply fourteen traditional indexing principles to study and demonstrate whether traditional principles of indexing are applicable for icon analysis. One of the fourteen indexing principles is first chosen for this analysis. A sample of fifteen library homepages is drawn from the total population of the United States library homepages. The investigators examine the structure of the selected homepages and non-icon information on the homepages. They examine icons as a visual form of knowledge representation (the structure and features of the icons) to determine how icons are representative of the information to which they are linked. The investigators assess how the icons on each library homepage satisfy the indexing principle chosen for the study. The article also provides an analysis of meanings of these icons. The investigators use semiotics theory to study the icons. The icons on the homepages of the WWW carry meaning dependent on the syntax of their use. They also carry paradigmatic meanings derived from other systems or domains. Codes and syntax are culturally constructed, which shape the meaning of messages conveyed in the icons. This study demonstrates whether traditional indexing principles are applicable for icons analysis in the WWW environment. It is hoped that the study will help designers of WWW homepages employ icon features that communicate effectively to their users and suggest using icons as a visual form for knowledge representation on the WWW

    Abstract
    Although classification has been an important aspect of astronomy since stellar spectroscopy in the late nineteenth century, to date no comprehensive classification system has existed for all classes of objects in the universe. Here we present such a system, and lay out its foundational definitions and principles. The system consists of the "Three Kingdoms" of planets, stars and galaxies, eighteen families, and eighty-two classes of objects. Gravitation is the defining organizing principle for the families and classes, and the physical nature of the objects is the defining characteristic of the classes. The system should prove useful for both scientific and pedagogical purposes.

    Abstract
    A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

    Abstract
    RLG has used METS for a particular application, that is as a wrapper for structural metadata. When RLG cultural materials was launched, there was no single way to deal with "complex digital objects". METS provides a standard means of encoding metadata regarding the digital objects represented in RCM, and METS has now been fully integrated into the workflow for this service.
