    Abstract
    Purpose The purpose of this paper is to describe a new method to improve the analysis of search engine results by considering the provider level as well as the domain level. This approach is tested by conducting a study using queries on the topic of insurance comparisons. Design/methodology/approach The authors conducted an empirical study that analyses the results of search queries aimed at comparing insurance companies. The authors used a self-developed software system that automatically queries commercial search engines and automatically extracts the content of the returned result pages for further data analysis. The data analysis was carried out using the KNIME Analytics Platform. Findings Google's top search results are served by only a few providers that frequently appear in these results. The authors show that some providers operate several domains on the same topic and that these domains appear for the same queries in the result lists. Research limitations/implications The authors demonstrate the feasibility of this approach and draw conclusions for further investigations from the empirical study. However, the study is a limited use case based on a limited number of search queries. Originality/value The proposed method allows large-scale analysis of the composition of the top results from commercial search engines. It allows using valid empirical data to determine what users actually see on the search engine result pages.

    Abstract
    This chapter shows that the wider use of Web search engines, reconsidering the theoretical and methodological frameworks to grasp new information practices. Beginning with an overview of the recent challenges implied by the dynamic nature of the Web, this chapter then traces the information behavior related concepts in order to present the different approaches from the user perspective. The authors pay special attention to the concept of "information practice" and other related concepts such as "use", "activity", and "behavior" largely used in the literature but not always strictly defined. The authors provide an overview of user-oriented studies that are meaningful to understand the different contexts of use of electronic information access systems, focusing on five approaches: the system-oriented approaches, the theories of information seeking, the cognitive and psychological approaches, the management science approaches, and the marketing approaches. Future directions of work are then shaped, including social searching and the ethical, cultural, and political dimensions of Web search engines. The authors conclude considering the importance of Critical theory to better understand the role of Web Search engines in our modern society.

    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
    This paper studies how varied damping factors in the PageRank algorithm influence the ranking of authors and proposes weighted PageRank algorithms. We selected the 108 most highly cited authors in the information retrieval (IR) area from the 1970s to 2008 to form the author co-citation network. We calculated the ranks of these 108 authors based on PageRank with the damping factor ranging from 0.05 to 0.95. In order to test the relationship between different measures, we compared PageRank and weighted PageRank results with the citation ranking, h-index, and centrality measures. We found that in our author co-citation network, citation rank is highly correlated with PageRank with different damping factors and also with different weighted PageRank algorithms; citation rank and PageRank are not significantly correlated with centrality measures; and h-index rank does not significantly correlate with centrality measures but does significantly correlate with other measures. The key factors that have impact on the PageRank of authors in the author co-citation network are being co-cited with important authors.

    Abstract
    Social phenomena happen, and the historians follow. So it goes with Google, the latest star shooting through the universe of trend-setting businesses. This company has even entered our popular lexicon: as many note, "Google" has moved beyond noun to verb, becoming an action which most tech-savvy citizens at the turn of the twenty-first century recognize and in fact do, on a daily basis. It's this wide societal impact that fascinated authors David Vise and Mark Malseed, who came to the book with well-established reputations in investigative reporting. Vise authored the bestselling The Bureau and the Mole, and Malseed contributed significantly to two Bob Woodward books, Bush at War and Plan of Attack. The kind of voluminous research and behind-the-scenes insight in which both writers specialize, and on which their earlier books rested, comes through in The Google Story. The strength of the book comes from its command of many small details, and its focus on the human side of the Google story, as opposed to the merely academic one. Some may prefer a dryer, more analytic approach to Google's impact on the Internet, like The Search or books that tilt more heavily towards bits and bytes on the spectrum between technology and business, like The Singularity is Near. Those wanting to understand the motivations and personal growth of founders Larry Page and Sergey Brin and CEO Eric Schmidt, however, will enjoy this book. Vise and Malseed interviewed over 150 people, including numerous Google employees, Wall Street analysts, Stanford professors, venture capitalists, even Larry Page's Cub Scout leader, and their comprehensiveness shows. As the narrative unfolds, readers learn how Google grew out of the intellectually fertile and not particularly directed friendship between Page and Brin; how the founders attempted to peddle early versions of their search technology to different Silicon Valley firms for $1 million; how Larry and Sergey celebrated their first investor's check with breakfast at Burger King; how the pair initially housed their company in a Palo Alto office, then eventually moved to a futuristic campus dubbed the "Googleplex"; how the company found its financial footing through keyword-targeted Web ads; how various products like Google News, Froogle, and others were cooked up by an inventive staff; how Brin and Page proved their mettle as tough businessmen through negotiations with AOL Europe and their controversial IPO process, among other instances; and how the company's vision for itself continues to grow, such as geographic expansion to China and cooperation with Craig Venter on the Human Genome Project. Like the company it profiles, The Google Story is a bit of a wild ride, and fun, too. Its first appendix lists 23 "tips" which readers can use to get more utility out of Google. The second contains the intelligence test which Google Research offers to prospective job applicants, and shows the sometimes zany methods of this most unusual business. Through it all, Vise and Malseed synthesize a variety of fascinating anecdotes and speculation about Google, and readers seeking a first draft of the history of the company will enjoy an easy read.

    "Das gesamte Wissen der Welt, das in honorigen Bibliotheken rund um den Globus gehütet wird, ist nur einen Maus-Klick entfernt. Google, das führende Internet-Suchmaschinen-Unternehmen aus den Vereinigten Staaten, möchte den Traum einer universellen Bibliothek verwirklichen. Aber für Autoren und Verlage stellt sich das Vorhaben eher als Albtraum dar. Sie sehen Urheberrechte und ihre Pfründe in Gefahr. Googles neuer Geschäftszweig "Print" ist unterteilt in ein Verlagsprogramm, bei dem Bücher von Verlagen gezielt beworben werden können, und das umstrittene Bibliotheksprogramm. Das Unternehmen möchte 15 Millionen Bücher aus den Beständen der renommierten Universitätsbibliotheken Harvard, Stanford, Oxford, Michigan und der öffentlichen Bibliothek New Yorks über den Index seiner Suchmaschine teilweise verfügbar machen. Seit Dezember läuft die Testphase von "Google Print". Benutzer können online nach einem bestimmten Buchtitel oder Begriff suchen. Google stellt bei Übereinstimmungen mit dem Suchbegriff eine Verknüpfung zu diesem Buch her. Öffentlich zugängliche Bücher, die nicht mehr urheberrechtlich geschützt sind, können vollständig, alle anderen nur auf maximal drei Seiten eingesehen werden. Google verweist auf bibliografische Daten, auf Bibliotheken, in den das Buch ausgeliehen oder einen Online-Buchhändler, bei dem es gekauft werden kann. Glaubt man dem Unternehmen, dann verfolgt es mit dem Bibliotheksprojekt nur hehre Ziele: Bei der Suche nach Büchern zu helfen, die woanders nicht zu finden sind und langfristig mit Autoren und Verlegern einen umfassenden, virtuellen Katalog aller Bücher aller Sprachen zu erstellen. Autoren, aber auch Verleger haben an dieser, Version erhebliche Zweifel. "Authors Guild", eine Vereinigung amerikanischer Autoren, hat im September beim Bezirksgericht Manhattan Klage eingereicht. Mit der Übernahme eines Buches in eine Bibilothek werde dieses nicht zum Teil eines Allgemeinguts. Die Erstellung von elektronischen Kopien bedeute eine massive und fortgesetzte Urheberrechtsverletzung. Auch der Amerikanische, Verband der Buchverlege, die "Association of American Publishers" hat sich der Klage angeschlossen. ,Google verletze die Urheberrechte der Verlage, um seine eigenen kommerziellen Interessen voranzutreiben. In der Buchbranche wird nämlich vermutet, dass Google langfristig selbst in den Buchhandel einsteigen könnte, wie Daniel Lenz, Redakteur des "buchreports" sagt. Leidtragende der neuen Entwicklung sei der stationäre Buchhandel, dem langfristig die Kunden fehlen würden.
