    "Fachleute sagten im Juli 1999 voraus, heute werde es mehr als 100 Millionen Domainnamen geben. Die Schätzung ging daneben: Derzeit gibt es nur halb so viele Internet-Adressen. Die befürchteten Probleme dagegen sind schon da: Eingängige Bezeichnungen in populären Namensräumen wie.com oder. net sind knapp und bisweilen teuer: So wurde wallstreet com für gut eine Million Euro verkauft. Neue Adressen, die die Netzverwaltung Icann seit zwei Jahren schrittweise einführt, sollten Abhilfe schaffen. Doch nach den bisherigen Erfahrungen sieht es nicht so aus, als seien.info oder.bix eine Lösung. Sieben neue Namensräume hat Icann genehmigt. Der letzte -.pro für Ärzte, Anwälte und Steuerberater - startet in den nächsten Wochen. Die erfolgreichste neue Top-Level-Domains (TLD) ist info mit mehr als einer Million registrierter Adressen. Doch nur 18 Prozent werden tatsächlich für Inhalte genutzt, sagt Tim Schumacher, Geschäftsführer der Plattform für Domainhandel Sedo: "Ein Großteil ist ungenutzt in den Händen von Spekulanten." 8000 Euro kostet etwa fonds.info. Über Zahlen kann man streiten. Der Verwalter der.info-Domeins Afilias spricht von weit mehr aktiven Seiten. Dennoch ist klar: Der allgemein zugängliche .info-Na-mensraum ist wohl deshalb so erfolgreich, weil Markeninhaber und Spekulanten sich auf die Adressen stürzten. Die einen vorbeugend, die anderen in der Hoffnung auf das große Geschäft. Exemplarisch ist der Streit zwischen Bundespresseamt und einer Duisburger Internet Agentur um bundesregierung.info. Grund für die Probleme: Es mangelt an Systematik im Namensraum. In den Vereinigten Staaten wissen die meisten Nutzer, dass unter whitehouse.net nicht Regierungsmitglieder gebrauchte Spionageflugzeuge verscherbeln, sondern Scherzbolde. Der echte Staatschef findet man unter der Endung.gov für Government (Regierung). International fehlt Vergleichbares; daher die Nöte des Bundespresseamts. Mehr als die Hälfte der weltweit registrierten Adressen liegt in globalen, allgemein offenen Namensräumen wie .com, .org oder.net. Der große Rest fällt in die Länder-Domeins wie de. Die neuen, nur für kleine Zielgruppen registrierbaren Nischenangebote sind bislang kein Erfolg. Was allerdings auch an der Auswahl liegen kann. So ist.coop Arbeitsgemeinschaften vorbehalten. Die Registrierzentrale freut sich über 7000 Anmeldungen-unter anderem von einer landwirtschaftlichen Kooperative aus der Mongolei. Eine Top Level Domain wie mobile für Mobilfunkunternehmen wäre erfolgreicher gewesen. Auch für den Namensbereich name malte sich die "Global Name Registry" mehr Interesse aus. Von etwa einer Million Kunden in 18 Monaten war die Rede. Derzeit sind es etwa 150000. Die Firma bleibt jedoch optimistisch: "Es gibt weltweit vielleicht 25 Millionen Unternehmen mit Interesse an Domainnamen, aber potenziell 600 Millionen Individuen", sagt Mitgründer Hakon Haugnes. Ein Beispiel für sinnvolle Lösungen ist der .aero-Namensraum. Dort gelten Benennungsstandards. Viele weltweit etablierte Codes für Fluggesellschaften führen zum Ziel; Ba.aero kann zum Beispiel nur British Airways registrieren. Derzeit diskutiert die Vergabezentrale eine Ausweitung der Regelung auf die standardisierten Flughafen-Codes und Flugnummern. Das Problem: Solche Vorgaben existieren nur selten a priori. Meist müssten sie mit dem Namensbereich geschaffen werden. Hier kritisiert der US-Rechtsprofessor Milton Mueller scharf die Organisation zur Verwaltung des Namensystems Icann: "Sie haben weder für die Einteilung, noch für die Aufteilung der Ressource Namensraum verbindliche Methoden definiert. Sie arbeiten als ein zentrales Planungsbüro im Sowjetstil und entscheiden nach absolut beliebigen Herangehensweisen auf Ad-hoc-Basis, welche Top Level Domains es gibt, wie sie verteilt werden, wer sie verwaltet." Icann wehrt sich mit der Begründung, sie dürfe als Selbstregulierungs-Organisation keine Politik betreiben.

    Abstract
    Reports results of a study of 4 WWW search engines: AltaVista; Lycos; Excite and WebCrawler to collect data on Web objects on polymer chemistry. 1.037 Web objects were examined for data in 4 categories: document information; use of meta fields; use of images and use of chemical names. Issues raised included: whether to provide metadata elements for parts of entities or whole entities only, the use of metasyntax, problems in representation of special types of objects, and whether links should be considered when encoding metadata. Use of metafields was not widespread in the sample and knowledge of metafields in HTML varied greatly among Web object creators. The study formed part of a metadata project funded by the OCLC Library and Information Science Research Grant Program

    Abstract
    Traditional cataloguing practices have been geared to printed materials or other materials that have fixed forms. The advent of electronic library materials poses new challenges for cataloguing as electronic objects may exist in multiple and changing versions. Discusses current attempts to organize electronic information objects in a world that is messy, volatile and uncontrolled and traces library cataloguing from manual to electronic organization. Electronic text may be available as a standalone ASCII, PostScript or another file. The file can reside on a floppy disk or on a minicomputer or mainframe computer as a file with a URL address and directory path. Briefly reviews some Internet indexing projects and prototypes, presents a vision of what cataloguing could evolve into the electronic world and discusses what needs to be done to realise this vision

    Abstract
    Indexing remains one of the most popular tools provided by digital libraries to help users identify and understand the characteristics of the information they need. Despite extensive studies of the problem of automatic index construction for text-based digital libraries, the construction of multimedia digital libraries continues to represent a challenge, because multimedia objects usually lack sufficient text information to ensure reliable index learning. This research attempts to tackle the problem of automatic index construction for multimedia objects by employing Web usage logs and limited keywords pertaining to multimedia objects. The tests of two proposed algorithms use two different data sets with different amounts of textual information. Web usage logs offer precious information for building indexes of multimedia digital libraries with limited textual information. The proposed methods generally yield better indexes, especially for the artwork data set.

    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
    Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

    Abstract
    The paper examines the way in which classification schemes can be applied to the organization of digital resources. The case is argued for the particular suitability of schemes based an faceted principles for the organization of complex digital objects. Details are given of a co-operative project between the School of Library Archive & Information Studies, University College London, and the United Kingdom Higher Education gateways Arts and Humanities Data Service and Humbul, in which a faceted knowledge structure is being developed for the indexing and display of digital materials within a new combined humanities portal.

    Abstract
    We present CopeOpi, an opinion-analysis system, which extracts from the Web opinions about specific targets, summarizes the polarity and strength of these opinions, and tracks opinion variations over time. Objects that yield similar opinion tendencies over a certain time period may be correlated due to the latent causal events. CopeOpi discovers relationships among objects based on their opinion-tracking plots and collocations. Event bursts are detected from the tracking plots, and the strength of opinion relationships is determined by the coverage of these plots. To evaluate opinion mining, we use the NTCIR corpus annotated with opinion information at sentence and document levels. CopeOpi achieves sentence- and document-level f-measures of 62% and 74%. For relationship discovery, we collected 1.3M economics-related documents from 93 Web sources over 22 months, and analyzed collocation-based, opinion-based, and hybrid models. We consider as correlated company pairs that demonstrate similar stock-price variations, and selected these as the gold standard for evaluation. Results show that opinion-based and collocation-based models complement each other, and that integrated models perform the best. The top 25, 50, and 100 pairs discovered achieve precision rates of 1, 0.92, and 0.79, respectively.

    Abstract
    Webcasting systems were developed to provide remote access in real-time to live events. Today, these systems have an additional requirement: to accommodate the "second life" of webcasts as archival information objects. Research to date has focused on facilitating the production and storage of webcasts as well as the development of more interactive and collaborative multimedia tools to support the event, but research has not examined how people interact with a webcasting system to access and use the contents of those archived events. Using an experimental design, this study examined how 16 typical users interact with a webcasting system to respond to a set of information tasks: selecting a webcast, searching for specific information, and making a gist of a webcast. Using several data sources that included user actions, user perceptions, and user explanations of their actions and decisions, the study also examined the strategies employed to complete the tasks. The results revealed distinctive system-use patterns for each task and provided insights into the types of tools needed to make webcasting systems better suited for also using the webcasts as information objects.

    Abstract
    1. Die Ausgangssituation Die Württembergische Landesbibliothek (WLB), größte Bibliothek Baden-Württembergs, war in der Vergangenheit durch die Zettelkataloge auf der Hauptebene stark geprägt. Nach erfolgreicher Digitalisierung des alten Alphabetischen Kataloges wurde auch über die Zukunft des Systematischen Zettelkataloges nachgedacht. Wenngleich dessen Benutzung rückläufig war und sein Standort dafür zu prominent, wurde er in einer Benutzerbefragung als unverzichtbares Rechercheinstrument bestätigt. Steigende Ausleihzahlen erforderten ein neues Raumkonzept: In Verlängerung der Ausleihe sollte ein Selbstabholerbereich entstehen und zwei Auskunftsplätze zu einem großzügigen Informationszentrum zusammengefasst werden. Forciert wurde das gesamte Vorhaben durch eine bereits terminierte Bausanierung, in deren Zusammenhang der Systematische Zettelkatalog ohnehin kurzfristig hätte umziehen oder ausgelagert werden müssen. 2. Kataloginhalt Der Inhalt des Kataloges (1996 abgebrochen zugunsten kooperativer Sacherschließung nach RSWK im Südwestdeutschen Bibliotheksverbund) sprach für Digitalisierung. In den Jahren 1930 bis 1995 für sämtliche Wissenschaftsfächer geführt, enthält er rückwärtig nahezu den gesamten magazinierten Bestand in den für die Sammeltradition und das Erwerbungsprofil wichtigen Fächern (Geschichte, Theologie, Recht, Musik, Kunst, Medizin, Württembergica einschließlich der Sondersammlungen). Ferner ist der Katalog über Jahrzehnte hinweg mit großem Personaleinsatz gepflegt worden und präsentiert die historisch ausgerichteten Fächer überwiegend in einer ständig fortentwickelten Systematik. Den schnellen Sucheinstieg bietet das Generalschlagwortregister, das unter orientierender Nutzung der Schlagwortnormdatei aktuell gehalten wurde.

    Abstract
    The availability of powerful indexing and database products with easy Web connections means that libraries able to gather and edit their own data are emancipated from the large vendors. The Oregon State Library staff used the Data Magician translation utility as part of a complex, but speedy, database converison project. The Oregon Index database of approximately 300.000 records was converted from a BRS database host over to the Inmagic WebPublisher system. Describes the planning and action stepts used in producing the Web accessible index database of considerable size. Participants have high ratings to effectiveness of both the translation utility and the database engine

    Abstract
    The days of the traditional abstracting and indexing services are waning, as abstracts and bibliographic data become commodities. However, there are tremedous opportunities for those organizations willing to look beyond the status quo to the new possibilities enabled by the latest wave of advanced technologies. Those who own content need to focus on the delivery mechanisms and new markets that technology can provide. Features like automatic extraction of key concepts or names, collaborative filtering to help with trend analysis, and visualization techniques can take information past the retrieval stage and into the management area
