- 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.

- 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.
