    Abstract
    In diesem Handbuch steht die Nutzerorientierung im Vordergrund. Namhafte Autoren aus Wissenschaft und Praxis beschäftigen sich in 16 Kapiteln mit Web-Suchmaschinen, die die Vorreiter hinsichtlich des sich verändernden Nutzerverhaltens sind. Das bei Google und Co. erlernte Verhalten wird auf andere Suchsysteme übertragen: die Website-Suche, die Intranet-Suche und die Suche in Spezialsuchmaschinen und Fachdatenbanken. Für alle Anbieter von Informationssystemen wird es zunehmend wichtig, einerseits die Arbeitsweise von Suchmaschinen zu kennen, andererseits mit dem Verhalten Ihrer Nutzer vertraut zu sein. Auf der Seite der Wissenschaftler werden Informatiker, Informationswissenschaftler, Medienwissenschaftler und Bibliothekswissenschaftler angesprochen. Für Entwickler bietet dieses Handbuch einen Überblick über Möglichkeiten für Suchsysteme, gibt Anregungen für Umsetzung und zeigt anhand von bestehenden Lösungen, wie eine Umsetzung aussehen kann. Für Entscheider, Rechercheure und Informationsvermittler bietet das Buch lesbare Überblicksartikel zu relevanten Themenbereichen, auf deren Basis eine Strategie für individuelle Suchlösungen erarbeitet werden kann. Als dritte Praktiker gruppe sind u.a. Berater, Lehrer, Journalisten und Politiker zu nennen, die sich zu den wichtigsten Themen rund um die Suche informieren möchten.

Weisel): "Mit dem vorliegenden Handbuch will der Herausgeber, Prof. Dr. Dirk Lewandowksi von der Hochschule für Angewandte Wissenschaften Hamburg, nach eigenen Worten eine Lücke füllen. Er hat renommierte Autoren aus unterschiedlichen Fachcommunities aufgerufen, zu dem Thema "Suchmaschinen im Internet" ihre unterschiedlichen Perspektiven in Form von Übersichtsartikeln zusammenzuführen. So möchte er mit diesem Band den Austausch zwischen den Communities sowie zwischen Wissenschaftlern und Praktikern fördern. . . . Empfehlung Dem Handbuch "Internet-Suchmaschinen" wird eine breite Leserschaft aus Wissenschaft und Praxis des Suchens und Findens im Web gewünscht, es sollte bei allen Einrichtungen für die Ausbildung des Fachnachwuchses zum Repertoire gehören, um diesen kritisch an die Thematik heranzuführen. Das gedruckte Werk wird der Aktualität und dem Wandel in diesem sehr dynamischen Fachgebiet Tribut zollen müssen. Statt einer zeitnahen Zweitausgabe sei dem Herausgeber und dem Verlag hier der Weg der kontinuierlichen Ergänzung empfohlen: um die oben genannten fehlenden Beiträge, aber auch sich neu ententwickelnde Inhalte - in Form eines lebendigen Lehrbuches -auf der geeigneten elektronischen Plattform."

    "Fünf Jahre nach seiner Gründung ist Google zum Herz des weltweiten Computernetzes geworden. Mit seiner Konzentration aufs Wesentliche hat die Suchmaschine alle anderen Anbieter weit zurück gelassen. Aber Google kann viel mehr, als im Web nach Texten und Bildern zu suchen. Gesammelt und aufbereitet werden auch Beiträge in Diskussionsforen (Newsgroups), aktuelle Nachrichten und andere im Netz verfügbare Informationen. Wer sich beim "Googeln" darauf beschränkt, ein einziges Wort in das Suchformular einzutippen und dann die ersten von oft mehreren hunderttausend Treffern anzuschauen, nutzt nur einen winzigen Bruchteil der Möglichkeiten. Wie man Google bis zum letzten ausreizt, haben Tara Calishain und Rael Dornfest in einem bislang nur auf Englisch veröffentlichten Buch dargestellt (Tara Calishain/Rael Dornfest: Google Hacks", www.oreilly.de, 28 Euro. Die wichtigsten Praxistipps kosten als Google Pocket Guide 12 Euro). - Suchen mit bis zu zehn Wörtern - Ihre "100 Google Hacks" beginnen mit Google-Strategien wie der Kombination mehrerer Suchbegriffe und enden mit der Aufforderung zur eigenen Nutzung der Google API ("Application Programming Interface"). Diese Schnittstelle kann zur Entwicklung von eigenen Programmen eingesetzt werden,,die auf die Google-Datenbank mit ihren mehr als drei Milliarden Einträgen zugreifen. Ein bewussteres Suchen im Internet beginnt mit der Kombination mehrerer Suchbegriffe - bis zu zehn Wörter können in das Formularfeld eingetippt werden, welche Google mit dem lo-gischen Ausdruck "und" verknüpft. Diese Standardvorgabe kann mit einem dazwischen eingefügten "or" zu einer Oder-Verknüpfung geändert werden. Soll ein bestimmter Begriff nicht auftauchen, wird ein Minuszeichen davor gesetzt. Auf diese Weise können bei einer Suche etwa alle Treffer ausgefiltert werden, die vom Online-Buchhändler Amazon kommen. Weiter gehende Syntax-Anweisungen helfen ebenfalls dabei, die Suche gezielt einzugrenzen: Die vorangestellte Anweisung "intitle:" etwa (ohne Anführungszeichen einzugeben) beschränkt die Suche auf all diejenigen Web-Seiten, die den direkt danach folgenden Begriff in ihrem Titel aufführen. Die Computer von Google bewältigen täglich mehr als 200 Millionen Anfragen. Die Antworten kommen aus einer Datenbank, die mehr als drei Milliarden Einträge enthält und regelmäßig aktualisiert wird. Dazu Werden SoftwareRoboter eingesetzt, so genannte "Search-Bots", die sich die Hyperlinks auf Web-Seiten entlang hangeln und für jedes Web-Dokument einen Index zur Volltextsuche anlegen. Die Einnahmen des 1998 von Larry Page und Sergey Brin gegründeten Unternehmens stammen zumeist von Internet-Portalen, welche die GoogleSuchtechnik für ihre eigenen Dienste übernehmen. Eine zwei Einnahmequelle ist die Werbung von Unternehmen, die für eine optisch hervorgehobene Platzierung in den GoogleTrefferlisten zahlen. Das Unternehmen mit Sitz im kalifornischen Mountain View beschäftigt rund 800 Mitarbeiter. Der Name Google leitet sich ab von dem Kunstwort "Googol", mit dem der amerikanische Mathematiker Edward Kasner die unvorstellbar große Zahl 10 hoch 100 (eine 1 mit hundert Nullen) bezeichnet hat. Kommerzielle Internet-Anbieter sind sehr, daran interessiert, auf den vordersten Plätzen einer Google-Trefferliste zu erscheinen.
    Da Google im Unterschied zu Yahoo oder Lycos nie ein auf möglichst viele Besuche angelegtes Internet-Portal werden wollte, ist die Suche in der Datenbank auch außerhalb der Google-Web-Site möglich. Dafür gibt es zunächst die "Google Toolbar" für den Internet Explorer, mit der dieser Browser eine eigene Leiste, für die Google-Suche erhält. Freie Entwickler bieten im Internet eine eigene Umsetzung: dieses Werkzeugs auch für den Netscape/ Mozilla-Browser an. Daneben kann ein GoogleSucheingabefeld aber auch auf die eigene WebSeite platziert werden - dazu sind nur vier Zei-len HTML-Code nötig. Eine Google-Suche zu starten, ist übrigens auch ganz ohne Browser möglich. Dazu hat das Unternehmen im Aprilvergangenen Jahres die API ("Application Programming Interface") frei gegeben, die in eigene Programme' eingebaut wird. So kann man etwa eine Google-Suche mit einer E-Mail starten: Die Suchbegriffe werden in die Betreff Zeile einer ansonsten leeren EMail eingetragen, die an die Adresse google@capeclear.com geschickt wird. Kurz danach trifft eine automatische Antwort-Mail mit den ersten zehn Treffern ein. Die entsprechenden Kenntnisse vorausgesetzt, können Google-Abfragen auch in Web-Services eingebaut werden - das sind Programme, die Daten aus dem Internet verarbeiten. Als Programmiertechniken kommen dafür Perl, PHP, Python oder Java in Frage. Calishain und Dornfest stellen sogar eine Reihe von abgedrehten Sites vor, die solche Programme für abstrakte Gedichte oder andere Kunstwerke einsetzen."

    Abstract
    The project proposes and tests a comprehensive and systematic model of user evaluation of Web search engines. The project contains two parts. Part I describes the background and the model including a set of criteria and measures, and a method for implementation. It includes a literature review for two periods. The early period (1995-1996) portrays the settings for developing the model and the later period (1997-2000) places two applications of the model among contemporary evaluation work. Part II presents one of the applications that investigated the evaluation of four major search engines by 36 undergraduates from three academic disciplines. It reports results from statistical analyses of quantitative data for the entire sample and among disciplines, and content analysis of verbal data containing users' reasons for satisfaction. The proposed model aims to provide systematic feedback to engine developers or service providers for system improvement and to generate useful insight for system design and tool choice. The model can be applied to evaluating other compatible information retrieval systems or information retrieval (IR) techniques. It intends to contribute to developing a theory of relevance that goes beyond topicality to include value and usefulness for designing user-oriented information retrieval systems.

    Abstract
    This is the first part of a two-part article that reviews 25 years of published research findings on end-user searching in online information retrieval (IR) systems. In Part 1 (Markey, 2007), the author seeks to answer the following questions: What characterizes the queries that end users submit to online IR systems? What search features do people use? What features would enable them to improve on the retrievals they have in hand? What features are hardly ever used? What do end users do in response to the system's retrievals? Are end users satisfied with their online searches? Summarizing searches of online IR systems by the search features people use everyday makes information retrieval appear to be a very simplistic one-stop event. In Part 2, the author examines current models of the information retrieval process, demonstrating that information retrieval is much more complex and involves changes in cognition, feelings, and/or events during the information seeking process. She poses a host of new research questions that will further our understanding about end-user searching of online IR systems.

    Abstract
    The explosion of the information available on the Internet has made traditional information retrieval systems, characterized by one size fits all approaches, less effective. Indeed, users are overwhelmed by the information delivered by such systems in response to their queries, particularly when the latter are ambiguous. In order to tackle this problem, the state-of-the-art reveals that there is a growing interest towards contextual information retrieval (CIR) which relies on various sources of evidence issued from the user's search background and environment, in order to improve the retrieval accuracy. This chapter focuses on mobile context, highlights challenges they present for IR, and gives an overview of CIR approaches applied in this environment. Then, the authors present an approach to personalize search results for mobile users by exploiting both cognitive and spatio-temporal contexts. The experimental evaluation undertaken in front of Yahoo search shows that the approach improves the quality of top search result lists and enhances search result precision.

    Abstract
    Evaluates the performance of 8 major Internet search engines in answering 21 real reference questions and 5 made up subject questions. Reports on the retrieval and relevancy ranking abilities of the search engines. Concludes that the search engines did not produce good results for the reference questions unlike for the subject questions. The best engines are identified by type of questions, with Infoseek best for the subject questions, and OpenText best for refrence questions

    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

    Abstract
    This is the second part of a two-part article that examines 25 years of published research findings on end-user searching of online information retrieval (IR) systems. In Part 1, it was learned that people enter a few short search statements into online IR systems. Their searches do not resemble the systematic approach of expert searchers who use the full range of IR-system functionality. Part 2 picks up the discussion of research findings about end-user searching in the context of current information retrieval models. These models demonstrate that information retrieval is a complex event, involving changes in cognition, feelings, and/or events during the information seeking process. The author challenges IR researchers to design new studies of end-user searching, collecting data not only on system-feature use, but on multiple search sessions and controlling for variables such as domain knowledge expertise and expert system knowledge. Because future IR systems designers are likely to improve the functionality of online IR systems in response to answers to the new research questions posed here, the author concludes with advice to these designers about retaining the simplicity of online IR system interfaces.

    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.
