    Abstract
    Suchmaschinen ermöglichen den Zugang zu Informationen im Internet und machen es als grenzenloses Informationsportal nutzbar. Netzinhalte, die nicht durch Suchmaschinen auffindbar sind, existieren für die Internetnutzer gar nicht - ein großes Gefahrenpotenzial für den einzelnen Nutzer und die Gesellschaft. Der vorliegende Band beleuchtet das Phänomen aus kommunikationswissenschaftlicher, rechtlicher, pädagogischer und technischer Perspektive.
    Footnote
    Rez. in: Mitt. VOEB 68(2015) H.1, S.180-183 (O.Oberhauser): "Aus dieser kurzen Skizze geht hervor, dass der vorliegende Band eine Reihe interessanter und mitunter auch brisanter Teilthemen beinhaltet. Wer an der Diskussion um die Rolle der meistgenutzten Suchmaschine in unserer Gesellschaft Interesse hat, findet in diesem Buch reichlich Material und Ideen. Jeder Beitrag wird zudem durch ein Literaturverzeichnis ergänzt, in dem weiterführende Quellen genannt werden. Die Beiträge sind durchweg "lesbar" geschrieben und nur in mässigem Ausmass von soziologischem oder rechtswissenschaftlichem Fachjargon durchsetzt. In stilistischer Hinsicht ist der Text dennoch nicht ohne Probleme, zumal bereits im ersten Absatz der Einleitung ein als Hauptsatz "verkaufter" Nebensatz auffällt ("Denn Suchmaschinenbetreiber wie Google ermöglichen und gestalten den Zugang zu Informationen im Netz.") und die gleiche stilistische Schwäche allein in der 19-seitigen Einleitung in über einem Dutzend weiterer Fälle registriert werden kann, vom nächsten Beitrag gar nicht zu sprechen. Ein funktionierendes Verlagslektorat hätte derlei rigoros bereinigen müssen. Es hätte eventuell auch dafür Sorge tragen können, dass am Ende des Bandes nicht nur ein Verzeichnis der Autorinnen und Autoren aufscheint, sondern auch ein Sachregister - ein solches fehlt nämlich bedauerlicherweise. In optischer Hinsicht ist der Hardcover-Band ansprechend gestaltet und gut gelungen. Der Preis liegt mit rund 80 Euro leider in der Oberklasse; auch die E-Book-Version macht die Anschaffung nicht billiger, da kein Preisunterschied zur gebundenen Ausgabe besteht. Dennoch ist das Buch aufgrund der interessanten Inhalte durchaus zu empfehlen; grössere Bibliotheken sowie kommunikations- und informationswissenschaftliche Spezialsammlungen sollten es nach Möglichkeit erwerben."

    Abstract
    Das Buch betrachtet das Thema Suchmaschinen ausgehend von der täglichen Recherche und führt in die technischen Grundlagen, in Recherchetechniken sowie die gesellschaftlichen und wirtschaftlichen Bedingungen der Recherche im Web ein. Suchmaschinen sind heute die wichtigsten Werkzeuge, um an Informationen zu gelangen. Wir verwenden Suchmaschinen täglich, meist ohne weiter darüber nachzudenken. Doch wie funktionieren diese Suchwerkzeuge eigentlich genau? Neben einer ausführlichen Darstellung der in den bekannten Suchmaschinen verwendeten Rankingverfahren wird auch ausführlich auf das Nutzerverhalten eingegangen, das wiederum die Ergebnisdarstellung prägt. Dazu kommen grundlegende Betrachtungen des Suchmaschinenmarkts, der Bedeutung der Suchmaschinenoptimierung und der Rolle der Suchmaschinen als technische Informationsvermittler. Nicht zuletzt wird auch die Seite der Recherche betrachtet und gezeigt, wie man mit den bekannten Suchmaschinen effizient recherchieren kann. Das Buch verhilft allen, die mit Suchmaschinen recherchieren oder sich beruflich mit der Optimierung, Aufbereitung und Sichtbarmachung von Inhalten beschäftigen, zu einem umfassenden Verständnis der Ansätze, Stärken und Schwächen verschiedener Suchmaschinen und der ihnen zugrunde liegenden Technologien.

    Abstract
    Suchmaschinen sind heute die wichtigsten Werkzeuge, um an Informationen zu gelangen. Wir verwenden Suchmaschinen täglich, meist ohne weiter darüber nachzudenken. Doch wie funktionieren diese Suchwerkzeuge eigentlich genau? Das Buch betrachtet Suchmaschinen aus vier Perspektiven: Technik, Nutzung, Recherche und gesellschaftliche Bedeutung. Es bietet eine klar strukturierte und verständliche Einführung in die Thematik. Zahlreiche Abbildungen erlauben eine schnelle Erfassung des Stoffs. Neben einer ausführlichen Darstellung der in den bekannten Suchmaschinen verwendeten Rankingverfahren wird auch ausführlich auf das Nutzerverhalten eingegangen, das wiederum die Ergebnisdarstellung prägt. Dazu kommen grundlegende Betrachtungen des Suchmaschinenmarktes, der Bedeutung der Suchmaschinenoptimierung und der Rolle der Suchmaschinen als technische Informationsvermittler. Das Buch richtet sich an alle, die mit Suchmaschinen zu tun haben und ein umfassendes Verständnis dieser Suchwerkzeuge erlangen wollen, u.a. Suchmaschinenoptimierer, Entwickler, Informationswissenschaftler, Bibliothekare, Rechercheure in Wissenschaft und Praxis sowie Online-Marketing-Verantwortliche. Für die zweite Auflage wurde der Text vollständig überarbeitet. Neben einem neuen Kapitel zur Suchmaschinenwerbung wurden zahlreiche Abschnitte zu neu aufgekommenen Themen hinzugefügt. Alle Statistiken und Quellen wurden auf den neuesten Stand gebracht.

    Abstract
    Nur wenige Unternehmen waren im Laufe der Geschichte so erfolgreich und gleichzeitig umstritten wie Google. Dem Autor Steven Levy wurde in bisher noch nie dagewesenem Umfang Zugang zum Unternehmen gestattet. In diesem aufschlussreichen Buch nimmt er die Leser mit in die Google-Zentrale, das Googleplex, um zu zeigen, wie Google arbeitet. Wie Levy enthüllt, liegt der Schlüssel zum Google-Erfolg einerseits in der technischen Denkweise sowie in der Ausübung typischer "Internet-Werte" wie Geschwindigkeit, Offenheit, Experimentier- und Risikofreude. Hat Google aber vielleicht seinen innovativen Biss verloren? In China ist es schwer gestolpert und Levy deckt auf, was dort schiefgelaufen ist und wie sich Brin und seine Kollegen bei der China-Strategie nicht einig waren. Und nun jagt Google bei seiner jüngsten Initiative, den sozialen Netzwerken, erstmals einem erfolgreichen Konkurrenten hinterher. Einige Mitarbeiter verlassen mittlerweile das Unternehmen in Richtung kleinerer, wendigerer Startups. Kann Google, das den berühmten Entschluss gefasst hat, nicht böse sein zu wollen, weiter wettbewerbsfähig bleiben? Kein anderes Buch konnte bisher die Google-Interna derart offenlegen.

    Abstract
    Suchmaschinen sind auf der einen Seite technische Werkzeuge, auf der anderen Seite erlangen sie durch die millionenfache tägliche Nutzung eine gesellschaftliche Bedeu-tung. Im dritten Band des Handbuch Internet-Suchmaschinen bieten führende Exper-ten aus Wissenschaft und Praxis einen Einblick in aktuelle Entwicklungen, neue Techno-logien und gesellschaftliche Auswirkungen der populären Suchdienste. Mit mittlerweile drei Bänden liegt das umfassendste deutschsprachige Werk zum The-ma Suchmaschinen vor, das alle wesentlichen Aspekte des Themas behandelt. Das Themenspektrum der bereits erschienenen Bände wird noch einmal wesentlich erwei-tert; wichtige Themen aus den vorangegangenen Bänden werden vertieft dargestellt. Damit ist das Handbuch auch ein unverzichtbares Nachschlagewerk zu allen Fragen rund um Suchmaschinen. Das Buch richtet sich an alle, die sich als Forscher, Entwickler oder Nutzer von Suchma-schinen mit dem Thema Suche beschäftigen.

    Abstract
    Zeigt übersichtlich die Usability anhand des Suchprozesses und der Mensch-Maschine-Interaktion mit den entstehenden Problemen auf. Bewertet die Kritikalität der identifizierten Usability-Probleme und verdeutlicht deren Auswirkungen auf die User Experience der Suche. Die konsequente Optimierung der User Experience und der Usability einer Suchmaschine ist Basis einer erfolgreichen Entwicklung von Websites. Suchmaschinen werden nicht nur als Funktion innerhalb von Websites eingesetzt, sondern kommen auch in unterschiedlichen Ausprägungen innerhalb von Applikationen, Online-Shops oder Intranets von Unternehmen vor. Die Autorin beschreibt, welche Evaluationsmethoden eingesetzt werden, um eine Suchmaschine zu optimieren, wo typische Probleme auftreten und wie sich diese auf die User Experience auswirken. Best-Practice-Beispiele und Tipps helfen sowohl Einsteigern als auch Experten bei der Umsetzung einer übergreifenden User Experience-Strategie und geben Hilfestellung bei der wirtschaftlichen Betrachtung im Rahmen der Produktentwicklung.

    Abstract
    Few companies in history have ever been as successful and as admired as Google, the company that has transformed the Internet and become an indispensable part of our lives. How has Google done it? Veteran technology reporter Steven Levy was granted unprecedented access to the company, and in this revelatory book he takes readers inside Google headquarters-the Googleplex-to show how Google works. While they were still students at Stanford, Google cofounders Larry Page and Sergey Brin revolutionized Internet search. They followed this brilliant innovation with another, as two of Google's earliest employees found a way to do what no one else had: make billions of dollars from Internet advertising. With this cash cow (until Google's IPO nobody other than Google management had any idea how lucrative the company's ad business was), Google was able to expand dramatically and take on other transformative projects: more efficient data centers, open-source cell phones, free Internet video (YouTube), cloud computing, digitizing books, and much more. The key to Google's success in all these businesses, Levy reveals, is its engineering mind-set and adoption of such Internet values as speed, openness, experimentation, and risk taking. After its unapologetically elitist approach to hiring, Google pampers its engineers-free food and dry cleaning, on-site doctors and masseuses-and gives them all the resources they need to succeed. Even today, with a workforce of more than 23,000, Larry Page signs off on every hire. But has Google lost its innovative edge? It stumbled badly in China-Levy discloses what went wrong and how Brin disagreed with his peers on the China strategy-and now with its newest initiative, social networking, Google is chasing a successful competitor for the first time. Some employees are leaving the company for smaller, nimbler start-ups. Can the company that famously decided not to be evil still compete? No other book has ever turned Google inside out as Levy does with In the Plex.

    Abstract
    Information seeking is a fundamental human activity. In the modern world, it is frequently conducted through interactions with search systems. The retrieval and comprehension of information returned by these systems is a key part of decision making and action in a broad range of settings. Advances in data availability coupled with new interaction paradigms, and mobile and cloud computing capabilities, have created a broad range of new opportunities for information access and use. In this comprehensive book for professionals, researchers, and students involved in search system design and evaluation, search expert Ryen White discusses how search systems can capitalize on new capabilities and how next-generation systems must support higher order search activities such as task completion, learning, and decision making. He outlines the implications of these changes for the evolution of search evaluation, as well as challenges that extend beyond search systems in areas such as privacy and societal benefit.

    Abstract
    The doctoral thesis of Tatiana Gossen formulates criteria and guidelines on how to design the user interfaces of search engines for children. In her work, the author identifies the conceptual challenges based on own and previous user studies and addresses the changing characteristics of the users by providing a means of adaptation. Additionally, a novel type of search result visualisation for children with cartoon style characters is developed taking children's preference for visual information into account.

    Abstract
    "Web Search Engine Research", edited by Dirk Lewandowski, provides an understanding of Web search engines from the unique perspective of Library and Information Science. The book explores a range of topics including retrieval effectiveness, user satisfaction, the evaluation of search interfaces, the impact of search on society, reliability of search results, query log analysis, user guidance in the search process, and the influence of search engine optimization (SEO) on results quality. While research in computer science has mainly focused on technical aspects of search engines, LIS research is centred on users' behaviour when using search engines and how this interaction can be evaluated. LIS research provides a unique perspective in intermediating between the technical aspects, user aspects and their impact on their role in knowledge acquisition. This book is directly relevant to researchers and practitioners in library and information science, computer science, including Web researchers.

    Abstract
    The main goal of this book is to transfer new research results from the fields of advanced computer sciences and information science to the design of new search engines. The readers will have a better idea of the new trends in applied research. The achievement of relevant, organized, sorted, and workable answers- to name but a few - from a search is becoming a daily need for enterprises and organizations, and, to a greater extent, for anyone. It does not consist of getting access to structural information as in standard databases; nor does it consist of searching information strictly by way of a combination of key words. It goes far beyond that. Whatever its modality, the information sought should be identified by the topics it contains, that is to say by its textual, audio, video or graphical contents. This is not a new issue. However, recent technological advances have completely changed the techniques being used. New Web technologies, the emergence of Intranet systems and the abundance of information on the Internet have created the need for efficient search and information access tools.
    Recent technological progress in computer science, Web technologies, and constantly evolving information available on the Internet has drastically changed the landscape of search and access to information. Web search has significantly evolved in recent years. In the beginning, web search engines such as Google and Yahoo! were only providing search service over text documents. Aggregated search was one of the first steps to go beyond text search, and was the beginning of a new era for information seeking and retrieval. These days, new web search engines support aggregated search over a number of vertices, and blend different types of documents (e.g., images, videos) in their search results. New search engines employ advanced techniques involving machine learning, computational linguistics and psychology, user interaction and modeling, information visualization, Web engineering, artificial intelligence, distributed systems, social networks, statistical analysis, semantic analysis, and technologies over query sessions. Documents no longer exist on their own; they are connected to other documents, they are associated with users and their position in a social network, and they can be mapped onto a variety of ontologies. Similarly, retrieval tasks have become more interactive and are solidly embedded in a user's geospatial, social, and historical context. It is conjectured that new breakthroughs in information retrieval will not come from smarter algorithms that better exploit existing information sources, but from new retrieval algorithms that can intelligently use and combine new sources of contextual metadata.
    With the rapid growth of web-based applications, such as search engines, Facebook, and Twitter, the development of effective and personalized information retrieval techniques and of user interfaces is essential. The amount of shared information and of social networks has also considerably grown, requiring metadata for new sources of information, like Wikipedia and ODP. These metadata have to provide classification information for a wide range of topics, as well as for social networking sites like Twitter, and Facebook, each of which provides additional preferences, tagging information and social contexts. Due to the explosion of social networks and other metadata sources, it is an opportune time to identify ways to exploit such metadata in IR tasks such as user modeling, query understanding, and personalization, to name a few. Although the use of traditional metadata such as html text, web page titles, and anchor text is fairly well-understood, the use of category information, user behavior data, and geographical information is just beginning to be studied. This book is intended for scientists and decision-makers who wish to gain working knowledge about search engines in order to evaluate available solutions and to dialogue with software and data providers.
