    Abstract
    Dieser Aufsatz beschäftigt sich mit den Grundsätzen der Informationsarchitektur im World Wide Web. Es werden die Faktoren dargestellt, die bei der Planung der Informationsarchitektur einer Website bedacht werden sollten. Sie erleichtern es dem Nutzer, Information zu finden und aufzunehmen. Eine Voraussetzung ist, die Struktur in der Konzeptionsphase zu optimieren, um eine nutzerfreundliche, erfolgreiche Website zu gestalten. Darüber hinaus werden Kriterien für die Navigation und das Labelsystem beschrieben, auf die Problematik der Suchfunktion eingegangen und das komplexe Thema der Metadaten und kontrollierten Vokabulare angerissen.

    Content
    "Wissenschaftler brauchen fundierte Informationen aus Quellen, auf die man sich verlassen kann. Die Suche nach solchen Quellen, wissenschaftlichen Aufsätzen, Dissertationen, Büchern, Datenbanken und Linklisten gestaltete sich bislang schwierig: Bibliotheken oder Verlage von Fachzeitschriften mussten einzeln angesteuert werden, einen zentralen, einheitlichen und einfachen Zugang gab es bislang, nicht. Das soll sich jetzt ändern: Das vom Bundesministerium für Bildung und Forschung (BMBF) und von der Deutschen; Forschungsgemeinsehaft (DFG) geförderte Internetportal "vascoda", das nach dem Willen seiner Initiatoren auch Grundbaustein für die "Digitale Bibliothek Deutschland" sein soll, will Forschern Zugang zu wissenschaftlicher Information unterschiedlichster Fachrichtungen und unterschiedlichster Formate bieten. Das ist bundesweit in dieser Form ebenso einzigartig wie die Tatsache, dass die an vascoda angeschlossenen Datenbanken ausschließlich ;,geprüfte" Informationen liefern sollen: "Fachbibliothekare und Fachwissenschaftler der Anbieter, die sich unter dem vascoda-Dach zusammengeschlossen haben, prüfen, welche Texte vdrfügbar gemacht werden", sagt Christine Burblies von der vascoda-Geschäftsstelle in Hannover. "So können wir gewährleisten, dass die Informationen wissenschaftlichen Ansprüchen genügen." Das macht dann auch den wesentlichen Unterschied zu anderen Suchmaschinen aus: Die Suchmaske des Wissenschaftsportals ist zwar ähnlich einfach zu handhaben wie die Internet-Suchmaschine Google - vascoda verirrt sich aber nicht im World Wide Web. Und während andere Internet-Suchmaschinen nicht den Zugriff auf das so genannte "invisible web" bieten, also beispielsweise auf Bibliothekskataloge, ermöglicht vascoda auch den Zugriff auf dieses unsichtbare Netz. Das Wissenschaftsportal ist unentgeltlich nutzbar, und auch ein Großteil der Informationen ist kostenlos zu beziehen. Es sind aber auch kostenpflichtige Informationen verfügbar - zum Beispiel aus Verlagsangeboten und kommerziellen Datenbanken. Wer Informationen etwa zu soziologischen Fragen sucht, landet sicher auch auf den Internetseiten des Instituts für Soziologie in Darmstadt (www.ifs.tu-darmstadt.de/forsch.htm), das ebenso zu den vascoda-Anbietern gehört wie das Deutsche Institut für Internationale Pädagogik (DIPF) in Frankfurt (www.dipfde/index_1024.htm). In vascoda eingebunden sind zur Zeit 23 virtuelle Fachbibliotheken (ViFas), die vier großen Informationsverbünde EconDoc (Wirtschaft), GetInfo (Naturwissenschaften und Technik), infoconnex (Pädagogik, Sozialwissenschaften, Psychologie) und Medizin sowie die Elektronische Zeitschriftenbibliothek (EZB), ein kooperativer Service von 209 Bibliotheken zur Bereitstellung von elektronischen Zeitschriften, -die im Internet publiziert werden. "Wir planen überdies die Erweiterung um das Fach Germanistik, und wenn es soweit ist, wird die Stadt- und Universitätsbibliothek Frankfurt diesen Service bereitstellen", sagt Burblies."

    Abstract
    This article provides an overview of recent developments relating to the application of thesauri in information organisation and retrieval on the World Wide Web. It describes some recent thesaurus projects undertaken to facilitate resource description and discovery and access to wide-ranging information resources on the Internet. Types of thesauri available on the Web, thesauri integrated in databases and information retrieval systems, and multiple-thesaurus systems for cross-database searching are also discussed. Collective efforts and events in addressing the standardisation and novel applications of thesauri are briefly reviewed.

    Abstract
    A study of the "real world" Web information searching behavior of 206 college students over a 10-month period showed that, contrary to expectations, the users adopted a more passive or browsing approach to Web information searching and became more eclectic in their selection of Web hosts as they gained experience. The study used a longitudinal transaction log analysis of the URLs accessed during 5,431 user days of Web information searching to detect changes in information searching behavior associated with increased experience of using the Web. The findings have implications for the design of future Web information retrieval tools

    Abstract
    The ever growing popularity of the Internet as a source of information, coupled with the accompanying growth in the number of documents made available through the World Wide Web, is leading to an increasing demand for more efficient and accurate information retrieval tools. Numerous techniques have been proposed and tried for improving the effectiveness of searching the World Wide Web for documents relevant to a given topic of interest. The specification of appropriate keywords and phrases by the user is crucial for the successful execution of a query as measured by the relevance of documents retrieved. Lack of users' knowledge an the search topic and their changing information needs often make it difficult for them to find suitable keywords or phrases for a query. This results in searches that fail to cover all likely aspects of the topic of interest. We describe a scheme that attempts to remedy this situation by automatically expanding the user query through the analysis of initially retrieved documents. Experimental results to demonstrate the effectiveness of the query expansion scheure are presented.

    Abstract
    The introduction and growth of the World Wide Web (WWW, or Web) have resulted in a profound change in the way individuals and organizations access information. In terms of volume, nature, and accessibility, the characteristics of electronic information are significantly different from those of even five or six years ago. Control of, and access to, this flood of information rely heavily an automated techniques for indexing and retrieval. According to Gudivada, Raghavan, Grosky, and Kasanagottu (1997, p. 58), "The ability to search and retrieve information from the Web efficiently and effectively is an enabling technology for realizing its full potential." Almost 93 percent of those surveyed consider the Web an "indispensable" Internet technology, second only to e-mail (Graphie, Visualization & Usability Center, 1998). Although there are other ways of locating information an the Web (browsing or following directory structures), 85 percent of users identify Web pages by means of a search engine (Graphie, Visualization & Usability Center, 1998). A more recent study conducted by the Stanford Institute for the Quantitative Study of Society confirms the finding that searching for information is second only to e-mail as an Internet activity (Nie & Ebring, 2000, online). In fact, Nie and Ebring conclude, "... the Internet today is a giant public library with a decidedly commercial tilt. The most widespread use of the Internet today is as an information search utility for products, travel, hobbies, and general information. Virtually all users interviewed responded that they engaged in one or more of these information gathering activities."
    Techniques for automated indexing and information retrieval (IR) have been developed, tested, and refined over the past 40 years, and are well documented (see, for example, Agosti & Smeaton, 1996; BaezaYates & Ribeiro-Neto, 1999a; Frakes & Baeza-Yates, 1992; Korfhage, 1997; Salton, 1989; Witten, Moffat, & Bell, 1999). With the introduction of the Web, and the capability to index and retrieve via search engines, these techniques have been extended to a new environment. They have been adopted, altered, and in some Gases extended to include new methods. "In short, search engines are indispensable for searching the Web, they employ a variety of relatively advanced IR techniques, and there are some peculiar aspects of search engines that make searching the Web different than more conventional information retrieval" (Gordon & Pathak, 1999, p. 145). The environment for information retrieval an the World Wide Web differs from that of "conventional" information retrieval in a number of fundamental ways. The collection is very large and changes continuously, with pages being added, deleted, and altered. Wide variability between the size, structure, focus, quality, and usefulness of documents makes Web documents much more heterogeneous than a typical electronic document collection. The wide variety of document types includes images, video, audio, and scripts, as well as many different document languages. Duplication of documents and sites is common. Documents are interconnected through networks of hyperlinks. Because of the size and dynamic nature of the Web, preprocessing all documents requires considerable resources and is often not feasible, certainly not an the frequent basis required to ensure currency. Query length is usually much shorter than in other environments-only a few words-and user behavior differs from that in other environments. These differences make the Web a novel environment for information retrieval (Baeza-Yates & Ribeiro-Neto, 1999b; Bharat & Henzinger, 1998; Huang, 2000).

    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.

    "Web searching is different from searching commercial IR systems. We can learn from search strategies recommended for searching IR systems, but most won't be effective for Web searching. Web searchers need strate gies that let search engines do the job they were designed to do. This article presents six new Web searching strategies that do just that."

    Abstract
    How do we find information an the Web? Although information on the Web is distributed and decentralized, the Web can be viewed as a single, virtual document collection. In that regard, the fundamental questions and approaches of traditional information retrieval (IR) research (e.g., term weighting, query expansion) are likely to be relevant in Web document retrieval. Findings from traditional IR research, however, may not always be applicable in a Web setting. The Web document collection - massive in size and diverse in content, format, purpose, and quality - challenges the validity of previous research findings that are based an relatively small and homogeneous test collections. Moreover, some traditional IR approaches, although applicable in theory, may be impossible or impractical to implement in a Web setting. For instance, the size, distribution, and dynamic nature of Web information make it extremely difficult to construct a complete and up-to-date data representation of the kind required for a model IR system. To further complicate matters, information seeking on the Web is diverse in character and unpredictable in nature. Web searchers come from all walks of life and are motivated by many kinds of information needs. The wide range of experience, knowledge, motivation, and purpose means that searchers can express diverse types of information needs in a wide variety of ways with differing criteria for satisfying those needs. Conventional evaluation measures, such as precision and recall, may no longer be appropriate for Web IR, where a representative test collection is all but impossible to construct. Finding information on the Web creates many new challenges for, and exacerbates some old problems in, IR research. At the same time, the Web is rich in new types of information not present in most IR test collections. Hyperlinks, usage statistics, document markup tags, and collections of topic hierarchies such as Yahoo! (http://www.yahoo.com) present an opportunity to leverage Web-specific document characteristics in novel ways that go beyond the term-based retrieval framework of traditional IR. Consequently, researchers in Web IR have reexamined the findings from traditional IR research.

    Content
    "Das World Wide, Web hat, wen wundert es, eine Vorgeschichte. Und zwar, und da staunt der Laie denn doch, im Internet. World Wide Web, Internet - ist denn das nicht dasselbe? Nein. Ist es nicht. Das WWW ist eine Funktion des Internet. Eine von vielen. So wie Email und Chat. Die Geschichte ist die. In den 40er Jahren des 20. Jahrhunderts wurden die ersten EDV-Anlagen gebaut. In den 60er und 70er Jahren gehörten riesige Computer mit Lochkarten, Magnetbändern und Endlos-Ausdrucken zu den Prestige-Objekten von Unis, , Banken und Firmen, ehrfürchtig "Elektronengehir ne" oder ironisch "Blechtrottel" genannt. 1957 hatte das US-Verteidigungsministerium unter dem Eindruck des Sputnik-Schocks die Forschungsinstitution ARPA gegründet. Zwölf jahre später entstand das ARPAnet - ein Projekt zur Entwicklung eines Forschungsnetzes, das Universitäten und zivile wie militärische US-Einrichtungen verband. Dass die treibende Kraft das Bedürfnis gewesen sein soll, das Netz vor Bomben zu schützen, ist wohl ein Gerücht. Nach Larry Roberts, einem der "Väter" des Internet, kam dieses Argument erst später auf. Es erwies sich als nützlich für das Aquirieren von Forschungsgeldern... Die globale elektronische Kommunikation blieb nicht auf die Welt der Akademiker beschränkt. Das Big Business begann die Lunte zu riechen. Fast überall, wanderten die Handelsmärkte vom Parkett und den Wandtafeln auf die Computerbildschirme: Das Internet war mittlerweile zu einem brauchbaren Datenübermittlungsmedium geworden, hatte aber noch einen Nachteil: Man konnte Informationen nur finden, wenn man wusste, wo man suchen muss. In den Folgejahren kam es zu einer Explosion in der Entwicklung neuer Navigationsprotokolle, es entstand als bedeutendste Entwicklung das WWW -übrigens im "alten Europa", am europäischen Forschungszentrum für Teilchenphysik (CERN) in Genf. Erfunden hat es Tim Berners-Lee. Seine Erfindung war eine doppelte. Zunächst die Anwendung des schon lange bekannten Hypertextprinzipes (Ted Nelson, 1972) auf elektronische Dokumente - in der Hypertext Markup Language (HTML). Und dann eine einfache von Herrn und Frau Jedermann bedienbare grafische Oberfläche, die diese Dokumente, austauscht und zur Anzeige bringt (über das Hypertext Transport Protokoll - HTTP). Die allererste Software hieß "Mosaic" und wird heute Browser genannt. Im April 1993 gab das CERN die World-Wide-Web-Software für. die Öffentlichkeit frei, zur unbeschränkten und kostenlosen Nutzung. Heute umfasst das WWW über 32 Millionen registrierte Domain-Namen, davon 5 Millionen .deDomains, und der weltweite Zugang zum Internet erreichte Ende 2002 über 620 Millionen Nutzer."

    Abstract
    Die sich rasant verändernde Informationslandschaft erfordert ein Umdenken in den verschiedenen Informations- und Dokumentationsstellen; es gibt kaum noch einen Arbeitsbereich, der nicht stetigen Umwälzungen unterworfen ist. Besonders in der Auskunftstätigkeit sehen wir uns mit neuen Herausforderungen konfrontiert, um der zunehmenden Disintermediation zu begegnen. Unseren Kunden stehen übers Internet vielfältige Wege zur Verfügung, um sich die Informationen selbst zu beschaffen, was jedoch meist dazu führt, dass sie sich in den Weiten des World Wide Web verlieren. Die Kompetenz und sachkundige Navigationshilfe der Informations- und Dokumentationsspezialisten wird demnach je länger, umso mehr gefordert sein; es verändert sich lediglich die Art und Weise des Auskunftgebens: ,Librarians need to more formally incorporate this awesome information power into a new model of service provision so that they may position themselves to meet the needs of reference services in the next century". Vor diesem Hintergrund drängt sich nicht nur ein anderes Vorgehen beim Kundeninterview auf, sondern es stellt sich ebenfalls die Frage, wie man die Informations- und Kommunikationstechnologien (l+K-Technologien) sinnvoll einsetzen kann, sowohl für den konventionellen als auch für den virtuellen Auskunftsdienst. Das zunehmende Aufkommen virtueller Universitäten verlangt nach neuen innovativen Ideen, um den potenziellen Studenten angemessene Dienstleistungen zu bieten, die es ihnen erlauben, das ganze Spektrum der l+K-Technologien voll auszuschöpfen. Virtuelle Auskunftsdienste bzw. "virtual reference desks" sind immer häufiger beliebte Themen in der Fachpresse und werden in Zukunft als entscheidender Wettbewerbsfaktor gelten. Wie kann man die vorhandenen Informationen so bündeln und kanalisieren, dass unsere Kunden so rasch und so effizient als möglich zu den von ihnen nachgefragten Inhalten kommen? Ein kurzer Überblick über den heutigen Entwicklungsstand der "virtual reference desks" zeigt auf, dass vor allem die "Internet Public Library" (IPL) auf diesem Gebiet Pionierarbeit geleistet hat, dass ihre Angebote jedoch nicht über E-Mail-Auskunft hinausgehen. Anhand eines dreistufigen Auskunftsmodells werden fortschrittliche Möglichkeiten aufgezeigt, wie man Fernauskunft unter Einbezug aller Internetdienste (E-Mail, Newsgroups, Chat, WWW) abwickeln und gestalten könnte, wobei vor allem technische Ansätze berücksichtigt werden, das ganze Umfeld einer virtuellen Universität jedoch nicht außer Acht gelassen wird.

    Abstract
    The World Wide Web (simplified here to "Web") is well-known for its "point and click" graphical user interface (GUI) and hyperlink search and navigate capabilities. When OPACs are placed in this operational context, users can easily hyperlink from a bibliographic display to related search terms, class marks, or bibliographic records. This hyperlinking capability is not available in most conventional text-based OPACs. As more and more users undertake their searches on Web-based information retrieval systems such as OPACs, it is natural to ask, "Are Web-based OPACs more effective retrieval systems than their conventional predecessors?" This paper presents the findings of an experimental study which compared users' search performance, assessments of ease of use, and satisfaction with search results after use of a Web OPAC or its conventional counterpart. The primary questions addressed by this research center on the influence of two experimental factors, OPAC search interface style and search task level of difficulty, on the dependent variables: actual search performance, perceptions of ease of use, and user assessments of satisfaction with search results. It was hypothesized that Web OPACs would be assessed as easier to use and that they would outperform conventional OPACs when measured by actual search results and users' levels of satisfaction with search results. Web OPAC searchers outperformed Text OPAC searchers, but search task level of difficulty is a major determinant of search success. The study also found little association between searchers' level of satisfaction with results and actual search performance

    Abstract
    The Internet can be a valuable tool allowing distance learners to access information not available locally. Search engines are the most common means of locating relevant information an the Internet, but to use them efficiently students should be taught the basics of searching and how to evaluate the results. This article briefly reviews how Search engines work, studies comparing Search engines, and criteria useful in evaluating the quality of returned Web pages. Research indicates there are statistical differences in the precision of Search engines, with AltaVista ranking high in several studies. When evaluating the quality of Web pages, standard criteria used in evaluating print resources is appropriate, as well as additional criteria which relate to the Web site itself. Giving distance learners training in how to use Search engines and how to evaluate the results will allow them to access relevant information efficiently while ensuring that it is of adequate quality.

    Abstract
    Education is a culturally and politically branded domain of knowledge and practice, and education specialists have traditionally remained somewhat isolated, communicating mainly on the general level of "basic educational principles." The expansion of the World Wide Web could change this situation; there exist on the Web a substantial number of education-related resources which have become accessible to international audiences. In this paper, the authors look at how these resources are organized with a view to answering two questions: (1) In a context of global exchanges, are education-related resources available on the Web organized in such a way as to maximize efficiency of identification and retrieval? (2) In virtual libraries with specialized collections on education, do categorization schemes and terminology reflect anything other than local perspectives and systems?

    Abstract
    This study investigated Simon's behavioral decisionmaking theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web, and considered the role of personal preferences in Web-based decisions. It employed a qualitative research methodology involving group interviews with 22 adolescent females. Data analysis took the form of iterative pattern coding using QSR NUD*IST Vivo qualitative data analysis software. Data analysis revealed that the study participants did operate within the limits of bounded rationality. These limits took the form of time constraints, information overload, and physical constraints. Data analysis also uncovered two major satisficing behaviors-reduction and termination. Personal preference was found to play a major role in Web site evaluation in the areas of graphic/multimedia and subject content preferences. This study has related implications for Web site designers and for adult intermediaries who work with young people and the Web

    Abstract
    Ein eigener Web-Auftritt ist heute für die meisten Bibliotheken selbstverständlich. Er bietet vielfältige Möglichkeiten, Serviceleistungen der Bibliothek einer breiten Öffentlichkeit rund um die Uhr anzubieten und das herkömmliche Leistungsspektrum um elektronische Dienste zu erweitern. Eine gelungene Website fördert die Zufriedenheit der Benutzer und bietet die Chance, ein neues auch räumlich entferntes Klientel als potenzielle Nutzer anzusprechen. Um diese Potenziale tatsächlich auch ausschöpfen zu können, müssen die Websites von Bibliotheken für ihre Besucher interessant und attraktiv sein. Dies stellt eine große Herausforderung dar. Weiche Aspekte dabei zu berücksichtigen sind, worin Defizite bestehen und welcher Handlungsbedarf daraus resultiert, wurde auf dem von der Kommission für Benutzung und Information des EDBI im November 2001 durchgeführten Round-Table "Bibliothekarische Websites" diskutiert (siehe dazu den Beitrag von Benno Homann in diesem Heft). Einig waren sich die dort zusammen gekommenen Experten darüber, dass die Websites von Bibliotheken stärker als bisher nutzerorientiert ausgerichtet sein sollten. Dies gilt auch und im Besonderen für deren Inhalte. Es lohnt sich daher, genauer darüber nachzudenken, was im Web angeboten werden soll und wie die Inhalte nutzerorientiert präsentiert werden können. Die folgenden Ausführungen liefern keine umfassenden Antworten auf diese Fragen, sondern sind eher als Anregungen zu verstehen, dem Ziel einer informativen nutzerorientierten Website näher zu kommen. Dieses Ziel wird wohl nie endgültig zu erreichen sein, aber es regt immer wieder dazu an, neue Wege der Annäherung zu suchen.
