    Abstract
    A modern information retrieval system must have the capability to find, organize and present very different manifestations of information - such as text, pictures, videos or database records - any of which may be of relevance to the user. However, the concept of relevance, while seemingly intuitive, is actually hard to define, and it's even harder to model in a formal way. Lavrenko does not attempt to bring forth a new definition of relevance, nor provide arguments as to why any particular definition might be theoretically superior or more complete. Instead, he takes a widely accepted, albeit somewhat conservative definition, makes several assumptions, and from them develops a new probabilistic model that explicitly captures that notion of relevance. With this book, he makes two major contributions to the field of information retrieval: first, a new way to look at topical relevance, complementing the two dominant models, i.e., the classical probabilistic model and the language modeling approach, and which explicitly combines documents, queries, and relevance in a single formalism; second, a new method for modeling exchangeable sequences of discrete random variables which does not make any structural assumptions about the data and which can also handle rare events. Thus his book is of major interest to researchers and graduate students in information retrieval who specialize in relevance modeling, ranking algorithms, and language modeling.

    Footnote
    Neben Anwendungen und Beispielen aus verschiedenen Ländern belegt der Autor anhand beeindruckender Beispiele, wie wenig sinnstiftend Wort-/Wortsstammfilter sind (Seite 84 bis 91). Ein Hauptproblem in der Informations- und Wissensgesellschaft sieht er darin: »Die Bequemlichkeit der Nutzer« führe zu einer selbst auferlegten »Informationsbeschränkung« bei der Nutzung von Suchmaschinen (Seite 18 bis 21). Dementsprechend sieht Strzolka in der »fehlenden Informationskompetenz und Zensur« eine »unheilvolle Allianz« (Seite 24). »Sich auf Suchmaschinen als objektive Instanz zu verlassen«, heißt es später (Seite 56), »ist so naiv, wie die Bibel als einzige Informationsquelle für das Leben in der modernen Welt zu nutzen«. Denn: »Suchmaschinen zensieren nicht - Ihre Betreiber organisieren Zensur.« Internetzensur Auf 25 Seiten (Seite 74 bis 99) dokumentiert Strzolka mit bemerkenswerten Beispielen, wie das in der Praxis geschieht. Nach Strzolka beteiligen sich Bibliothekare auch an der (Internet-)Zensur (Seite 22 f, mit Beispielen auf Seite 34). Hier wäre eine tiefergehende Auseinsandersetzung angebracht gewesen. Beeindruckend dabei, wie Strzolka über »Zensur und Idiotenfallen« (Seite 84 bis 90) berichtet. »Das Internet ist eine ausgesprochen heterogene Datensammlung und >keineswegs die größte Bibliothek der Welt>, wie immer zu hören ist.« (Seite 25) Denn: »Informationsportale verengen den Weg in die Wissensgesellschaft [...], weil sie die Fokussierung auf gewünschte Quellen [fördern]« (Seite 25). Vor diesem Hintergrund müsse deshalb eher von »Informationsbeschränkung« als von »Informationsvielfalt« die Rede sein.

    Abstract
    This book constitutes the refereed proceedings of the 11th European Conference on Research and Advanced Technology for Digital Libraries, ECDL 2007, held in Budapest, Hungary, in September 2007. The 36 revised full papers presented together with the extended abstracts of 36 revised poster, demo papers and 2 panel descriptions were carefully reviewed and selected from a total of 153 submissions. The papers are organized in topical sections on ontologies, digital libraries and the web, models, multimedia and multilingual DLs, grid and peer-to-peer, preservation, user interfaces, document linking, information retrieval, personal information management, new DL applications, and user studies.

    Rez. in: Mitt. VOEB 61(2008) H.2, S.70-72 (M. Katzmayr): "Beate Guba beschäftigt sich im vorliegenden Buch mit Webportalen, wobei insbesondere Universitätsportale behandelt werden. Tatsächlich kann sich das Informationsmanagement an Hochschulen über einen Mangel an Herausforderungen nicht beklagen: wie die Autorin einleitend darstellt, haben diese nämlich sowohl administrative als auch wissenschaftliche Informationen in sehr großer Menge zu verwalten. Dabei sind die für spezifische Informationen benötigten Datenquellen sowohl im administrativen als auch wissenschaftlichen Bereich oft voneinander isoliert und befinden sich in heterogenen Systemen - unerwünschte Redundanzen und Inkonsistenzen sind die Folge. Verbunden mit der verstärkten Nachfrage nach elektronisch vorliegenden Fachinformationen im Wissenschaftsbetrieb ist ein planmäßiges, strukturiertes und effizientes Umgehen mit Informationen notwendig. Ein Portal kann hier wertvolle Dienste leisten - doch was ist darunter eigentlich genau zu verstehen? Nach einer Auseinandersetzung mit der einschlägigen Literatur gelangt Guba zu folgender Arbeitsdefinition: "Ein Portal ist [...] ein virtueller Ort für die Bereitstellung und Distribution von (über verschiedene Anwendungen verteilte) Daten und Informationen und ermöglicht eine durchgängig IT-gestützte Prozessteuerung übertechnische Systemgrenzen hinweg [...] Ein universitäres Informations- und Kommunikationsportal hat also die Funktion, auf der einen Seite den Universitätsbetrieb und auf der anderen Seite die grundlegenden Bestandteile des Wissenschaftsprozesses, nämlich die Gewinnung, Speicherung, Publikation und Vermittlung von Informationen bzw. Wissen sowie die wissenschaftliche Kommunikation, zu unterstützen". Als weiteres wesentliches Merkmal von Portalen kommt noch die Möglichkeit der Personalisierung der Funktionen hinzu.

    Rez. in: Mitt VÖB 62(2009) H.1 (M. Buzinkay): "Normalerweise schreibe ich in einer Buchrezension zunächst über den Inhalt, die Relevanz und erst am Schluss eine persönliche Empfehlung. Nun mache ich es mal umgekehrt: Jeder Informationsspezialist sollte sich dieses Buch besorgen und daraus seine Schlüsse ziehen! Nach dieser ordentlichen Portion "Wachrütteln" komme ich zum vorliegenden Werk. Die mehr als 500 Seiten sind dicht gepackte Information und Wissen pur zu Google und was mar alles aus dieser Suchmaschine herausholen kann. Das sind teilweise Dinge, die man nicht glauben würde: Zutritt zu Firmenwebcams, Passwortdateien, Contentmanagementsystemen und Personendaten. Das Buch ist also keine Einführung in das 1 x 1 von Google, und trotzdem lassen sich mit den Grundfunktionen dieser Suchmaschine die verrücktesten Dinge anstellen und herausfinden. Wenn Sie das nächste Mal jemanden fragen sollten, ob er Google denn kenne und damit umgehen könne, dann können Sie das sicherlich gefallene "Ja" getrost in den digitalen Eimer schmeißen. Das, was Sie in diesem Buch lesen, haben sie zu 90% noch nicht gekannt. Und Sie sind Informationsexperte/in. Einige Auszüge aus dem Inhaltsverzeichnis geben Ihnen eine Ahnung, um was es in diesem Buch geht: Newsgroups durchsuchen, Verzeichnislisten aufspüren, Datenbanken erforschen, Daten von der Quelle abholen, fremde Angriffscodes entdecken, Sicherheitsabfragen formulieren, ... Das Schöne: man bekommt allerhand Beispiele geliefert, die man auch selbst (legal) ausprobieren kann. In Summe: sehr empfehlenswert!"
