    Abstract
    Aufgabe des Wissensmanagements ist es, den Mitarbeitern im Unternehmen entscheidungs- und handlungsrelevante Informationen bereitzustellen und die Mitarbeiter bei der intelligenten Verarbeitung dieser Informationen zu unterstützen. Ein hierzu genutztes Werkzeug von wachsender Bedeutung sind Unternehmensportale. Wir beschreiben kurz die Entwicklung von Portalen im World Wide Web (WWW), um dann Web-Portale von verschiedenen Arten von Unternehmensportalen abzugrenzen. Wir zeigen erwartete Funktionalitäten auf und stellen ein 5-Schichten Modell einer Gesamtarchitektur für Portale dar, welche die wesentlichen Komponenten umfasst. Im Anschluss werden die Besonderheiten der organisatorischen Realisierung und im Ausblick der Übergang von Portalen zum ,ubiquitous personalized information supply", der überall verfügbaren und individuellen Informationsversorgung behandelt

    Abstract
    This book provides practical strategies which enable the advanced web user to locate information effectively and to form a precise evaluation of the accuracy of that information. Although the book provides a brief but thorough review of the technologies which are currently available for these purposes, most of the book concerns practical `future-proof' techniques which are independent of changes in the tools available. For example, the book covers: how to retrieve salient information quickly; how to remove or compensate for bias; and tuition of novice Internet users.
    Content
    Key Features - Importantly, the book enables readers to develop strategies which will continue to be useful despite the rapidly-evolving state of the Internet and Internet technologies - it is not about technological `tricks'. - Enables readers to be aware of and compensate for bias and errors which are ubiquitous an the Internet. - Provides contemporary information an the deficiencies in web skills of novice users as well as practical techniques for teaching such users. The Authors Dr Alison Stacey works at the Learning Resource Centre, Cambridge Regional College. Dr Adrian Stacey, formerly based at Cambridge University, is a software programmer. Readership The book is aimed at a wide range of librarians and other information professionals who need to retrieve information from the Internet efficiently, to evaluate their confidence in the information they retrieve and/or to train others to use the Internet. It is primarily aimed at intermediate to advanced users of the Internet. Contents Fundamentals of information retrieval from the Internet - why learn web searching technique; types of information requests; patterns for information retrieval; leveraging the technology: Search term choice: pinpointing information an the web - why choose queries carefully; making search terms work together; how to pick search terms; finding the 'unfindable': Blas an the Internet - importance of bias; sources of bias; usergenerated bias: selecting information with which you already agree; assessing and compensating for bias; case studies: Query reformulation and longer term strategies - how to interact with your search engine; foraging for information; long term information retrieval: using the Internet to find trends; automating searches: how to make your machine do your work: Assessing the quality of results- how to assess and ensure quality: The novice user and teaching internet skills - novice users and their problems with the web; case study: research in a college library; interpreting 'second hand' web information.

    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.

    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
    The work we are presenting is devoted to the information collected on the WWW. By the term collected we mean the whole process of retrieving, extracting and presenting results to the user. This research is part of the RAP (Research, Analyze, Propose) project in which we propose to combine two methods: (i) query reformulation using linguistic markers according to a given point of view; and (ii) text semantic analysis by means of contextual exploration results (Descles, 1991). The general project architecture describing the interactions between the users, the RAP system and the WWW search engines is presented in Nait-Baha et al. (1998). We will focus this paper on showing how we use linguistic markers to reformulate the queries according to a given point of view

    Abstract
    Purpose - This article is an edited version of a report commissioned by the British Library and JISC to identify how the specialist researchers of the future (those born after 1993) are likely to access and interact with digital resources in five to ten years' time. The purpose is to investigate the impact of digital transition on the information behaviour of the Google Generation and to guide library and information services to anticipate and react to any new or emerging behaviours in the most effective way. Design/methodology/approach - The study was virtually longitudinal and is based on a number of extensive reviews of related literature, survey data mining and a deep log analysis of a British Library and a JISC web site intended for younger people. Findings - The study shows that much of the impact of ICTs on the young has been overestimated. The study claims that although young people demonstrate an apparent ease and familiarity with computers, they rely heavily on search engines, view rather than read and do not possess the critical and analytical skills to assess the information that they find on the web. Originality/value - The paper reports on a study that overturns the common assumption that the "Google generation" is the most web-literate.

    Abstract
    Because of the increasing presence of scientific publications an the Web, combined with the existing difficulties in easily verifying and retrieving these publications, research an techniques and methods for retrieval of scientific Web publications is called for. In this article, we report an the initial steps taken toward the construction of a test collection of scientific Web publications within the subject domain of plant biology. The steps reported are those of data gathering and data analysis aiming at identifying characteristics of scientific Web publications. The data used in this article were generated based an specifically selected domain topics that are searched for in three publicly accessible search engines (Google, AlITheWeb, and AItaVista). A sample of the retrieved hits was analyzed with regard to how various publication attributes correlated with the scientific quality of the content and whether this information could be employed to harvest, filter, and rank Web publications. The attributes analyzed were inlinks, outlinks, bibliographic references, file format, language, search engine overlap, structural position (according to site structure), and the occurrence of various types of metadata. As could be expected, the ranked output differs between the three search engines. Apparently, this is caused by differences in ranking algorithms rather than the databases themselves. In fact, because scientific Web content in this subject domain receives few inlinks, both AItaVista and AlITheWeb retrieved a higher degree of accessible scientific content than Google. Because of the search engine cutoffs of accessible URLs, the feasibility of using search engine output for Web content analysis is also discussed.

    Abstract
    Designing systematic access to Internet resources is a major item an the agenda of researchers and practitioners in the field of information science, and is the focus of this study. A critical analysis of classification schemes used in major portals and Web classified directories exposes inconsistencies in the way they classify Internet resources. The inconsistencies indicate that the developers fall to differentiate the various classificatory models, and are unaware of their different rationales. The study establishes eight classificatory models for resources available to Internet users. Internet resources can be classified by subjects, objects, applications, users, locations, reference sources, media, and languages. The first five models are contentrelated; namely they characterize the content of the resource. The other three models are formst-related; namely they characterize the format of the resource or its technological infrastructure. The study identifies and formulates the eight classificatory models, analyzes their rationales, and discusses alternative ways to combine them in a faceted integrated classification scheme.

    Rez. in BuB 56(2004) H.4, S.84-86 (D. Lewandowski): "Eines vorab: Sowohl der Titel als auch der Klappentext dieses Bandes sind irreführend. Man würde annehmen, dass es sich um einen weiteren Ratgeber zur Internetre-cherche handelt; dies ist jedoch nicht der Fall. Vielmehr untersucht der Autor das Rechercheverhalten so genannter Internetexperten, wobei ein »Experte« hier durch seine (mehrjährige) Erfahrung mit dem Internet definiert wird. Eine formale Ausbildung spielt keine Rolle: »Bezüglich ihrer Web-Kenntnisse sind die Teilnehmer [der Untersuchungen] als Autodidakten zu beschreiben, die sich ihr Wissen über die Jahre eigenständig, zum Teil als Hobby, insbesondere aber im Rahmen eines training-onthe job selbst angeeignet haben« (Seite 102). - Zwei Vergleichsstudien - Nach einführenden Kapiteln über die Expertiseforschung in der Psychologie, ihrer Anwendung auf Fragen des Information Retrieval und Betrachtungen über das Konzept des Hypertexts sowie einem Uberblick über Nutzerstudien im Bereich der Websuche kommt der Autor zum Kernpunkt seines Werks. Er besteht aus zwei Untersuchungen, die der Verfasser im Rahmen seines Dissertationsprojekts, dessen Ergebnisse das vorliegende Buch darstellt, durchgeführt hat. Für die erste Studie machte der Autor Interviews mit den Versuchspersonen, um ihre grundsätzlichen Recherchestra tegien kennen zu lernen und anhand der Ergebnisse ein Ablaufdiagramm typischer Internetrecherchen zu erstellen. In einem zweiten Schritt mussten die Versuchspersonen einige Suchaufgaben lösen. Dabei wurde beobachtet, inwieweit sich das Suchverhalten der Experten von demjenigen des durchschnittlichen Nutzers unterscheidet. Der Vergleich erfolgte auf Basis eines Rechercheprotokolls (Query Log) der Suchmaschine Fireball. Ergebnis war unter anderem, dass die Experten häufiger Operatoren und die Möglichkeit der Phrasensuche nutzten und dass ihre Anfragen aus durchschnittlich mehr Suchbegriffen bestanden. In der zweiten Studie wurde eine Expertengruppe direkt mit Internetanfängern verglichen. Die Aufgabenstellungen kamen aus dem Bereich der Volkswirtschaft (Euro-Umstellung). Die Versuchsteilnehmer wurden in vier Gruppen aufgeteilt: jeweils Anfänger und Experten mit beziehungsweise ohne volkswirtschaftliche Vorkenntnisse. Das Ergebnis war, dass die Gruppe der »Doppelexperten« deutlich bessere Resultate erzielte als Teilnehmer der anderen Gruppen. Erfahrungen nur im volkswirtschaftlichen Bereich oder aber in Bezug auf die Internetrecherche reichten nicht aus, um die Aufgaben besser zu lösen als die so genannten Doppellaien. Allerdings stellt der Autor selbst fest, dass der Schwierigkeitsgrad der gestellten Aufgaben für die Versuchspersonen zu hoch war. Besonders gravierend war dies bei der letzten Aufgabe. Diese konnten von den 47 Teilnehmern nur zwei erfolgreich bearbeiten; interessanterweise ein Doppelexperte und ein Doppellaie. Unter anderem diese Feststellung stellt die Kriterien für einen »Web-Experten« infrage. Interessant wäre es gewesen, wenn anstatt der Abgrenzung durch das Kriterium Web-Erfahrung »wirkliche« Experten wie Bibliothekare und Informationsvermittler die untersuchte Expertengruppe gebildet hätten. Zwar hätten sich bei dem aufgezeichneten exemplarischen Ablauf einer Recherche wohl keine gravierenden Unterschiede ergeben, wahrscheinlich aber bei der Lösung der Suchaufgaben. Die im Anhang abgedruckten Aufgaben erscheinen auch für den nicht volkswirtschaftlich gebildeten Profi als nicht übermäßig schwierig. Die Aussage, dass nur Doppelexperten Suchaufgaben besser lösen können als Anfänger in beiden Bereichen, ist also durchaus fragwürdig. Der Autor kommt zu dem Schluss, dass »inhaltliches Wissen - zumindest für sehr spezifische, inhaltlich anspruchsvolle Aufgaben - als Hilfsmittel der Recherche nur schwer zu kompensieren [ist] « (Seite 185). Dem ist bei hoch spezialisierten Fragestellungen sicherlich zuzustimmen; dabei sollte allerdings eine klare Grenze gesetzt werden, was denn nun sehr spezifische Aufgaben sind.

    Abstract
    Adapting the consumer behavior selectivity model to the Web environment, this paper's key contribution is the introduction of a self-concept orientation model of Web information seeking. This model, which addresses gender, effort, and information content factors, questions the commonly assumed equivalence of sex and gender by specifying the measurement of gender-related selfconcept traits known as self- and other-orientation. Regression analyses identified associations between self-orientation, other-orientation, and self-reported search frequencies for content with identical subject domain (e.g., medical information, government information) and differing relevance (i.e., important to the individual personally versus important to someone close to him or her). Self- and other-orientation interacted such that when individuals were highly self-oriented, their frequency of search for both self- and other-relevant information depended on their level of other-orientation. Specifically, high-self/high-other individuals, with a comprehensive processing strategy, searched most often, whereas high-self/low-other respondents, with an effort minimization strategy, reported the lowest search frequencies. This interaction pattern was even more pronounced for other-relevant information seeking. We found no sex differences in search frequency for either self-relevant or other-relevant information.

    Abstract
    Enormous expanses of the Internet are unreachable with standard Web search engines. This book provides the key to finding these hidden resources by identifying how to uncover and use invisible Web resources. Mapping the invisible Web, when and how to use it, assessing the validity of the information, and the future of Web searching are topics covered in detail. Only 16 percent of Net-based information can be located using a general search engine. The other 84 percent is what is referred to as the invisible Web-made up of information stored in databases. Unlike pages on the visible Web, information in databases is generally inaccessible to the software spiders and crawlers that compile search engine indexes. As Web technology improves, more and more information is being stored in databases that feed into dynamically generated Web pages. The tips provided in this resource will ensure that those databases are exposed and Net-based research will be conducted in the most thorough and effective manner. Discusses the use of online information resources and problems caused by dynamically generated Web pages, paying special attention to information mapping, assessing the validity of information, and the future of Web searching.
