- Abstract
- Interested in how an efficient search engine works? Want to know what algorithms are used to rank resulting documents in response to user requests? The authors answer these and other key information on retrieval design and implementation questions is provided. This book is not yet another high level text. Instead, algorithms are thoroughly described, making this book ideally suited for both computer science students and practitioners who work on search-related applications. As stated in the foreword, this book provides a current, broad, and detailed overview of the field and is the only one that does so. Examples are used throughout to illustrate the algorithms. The authors explain how a query is ranked against a document collection using either a single or a combination of retrieval strategies, and how an assortment of utilities are integrated into the query processing scheme to improve these rankings. Methods for building and compressing text indexes, querying and retrieving documents in multiple languages, and using parallel or distributed processing to expedite the search are likewise described. This edition is a major expansion of the one published in 1998. Neuaufl. 2005: Besides updating the entire book with current techniques, it includes new sections on language models, cross-language information retrieval, peer-to-peer processing, XML search, mediators, and duplicate document detection.

Wiesenmüller): "In erster Linie für am Thema Sacherschließung Interessierte ist dieses neue Lehrbuch, das der Düsseldorfer Informationswissenschaftler Wolfgang G. Stock gemeinsam mit Mechtild Stock verfasst hat. Als primäre Zielgruppe werden Studierende der »Informationswissenschaft, Informatik und Wirtschaftsinformatik, Wirtschaftswissenschaften, Informationswirtschaft, Information und Dokumentation, Bibliothekswesen, Computerlinguistik« (Seite XVI) genannt; daneben sind auch Praktiker aus diesen Bereichen angesprochen. In Abgrenzung zu anderen, stärker praktisch ausgerichteten Lehrbüchern wie etwa Jutta Bertrams »Einführung in die inhaltliche Erschließung«' haben die Autoren den Anspruch, einen »ausgewogenen Ausgleich [...] zwischen Theorie und Praxis« und »zwischen den beteiligten Wissenschaftsdisziplinen, vor allem Informationswissenschaft, Informatik und Bibliothekswissenschaft« (Seite XIII) zu bieten. Die Aufmachung des Bandes als eigenständige Monografie führt etwas in die Irre, denn faktisch handelt es sich um den zweiten Teil der »Einführung in die Informationswissenschaft«. Diese wird im Vorwort als Reihe bezeichnet, scheint aber von der Sache her eher ein mehrbändiges Werk zu sein. Tatsächlich wird im Text häufig auf den ersten Teil »Information Retrieval« verwiesen und empfohlen, beide Bände nebeneinander zu verwenden (Seite XVI). . . .
Weitere Rez. in: Mitt. VOEB 61(1008) H.3, S. 137-138 (E. Pipp): "Wissensrepräsentation befasst sich mit Verfahrensweisen, das in Dokumenten vorgefundene Wissen so zu repräsentieren, zu organisieren oder zu ordnen, dass es in Bibliothekskatalogen, Datenbanken, im World Wide Web oder in unternehmensinternen Informationsdiensten optimal aufgefunden werden kann. Wissensrepräsentation befasst sich mit Werkzeugen zur Indexierung, mit dem täglichen Brot und der täglichen Mühsal unserer Berufsgruppe, und somit sollte ein Fachbuch zu diesem Thema auf unserer Leseliste ganz weit oben stehen. . . . Alles in allem: ein Buch, das Lehrgangsteilnehmer und -teilnehmerinnen umfassend in dasThema einführt, das aber auch Bibliothekaren und Bibliothekarinnen mit Berufserfahrung die Konzepte (wieder) bewusst macht, die hinter ihren täglich verwendeten Arbeitswerkzeugen stehen und ihnen manches Neue bieten kann."
Weitere Rez. in: ZfBB 56(2009) H.2, S.131-133 (J. Bertram): "Alles in allem gelingt es den Autoren aber, ein facettenreiches, umfassendes und detailliertes Bild der Wissensorganisation und -repräsentation zu zeichnen, das durch eine Fülle von Literatur fundiert und zugleich praxisorientiert ist. Die behandelten Inhalte gehen über Grundlagen erheblich hinaus. Dies ist einerseits eine Schwäche des Buchs, zugleich aber auch seine Stärke. Als Novize mag man mit ihm zu kämpfen haben, als Experte wird man viele wertvolle Anregungen finden und noch die eine oder andere Wissenslücke schließen können. Entlastendes bieten die Autoren zudem all denjenigen, die von der Wichtigkeit der von einigen bereits als Anachronismus abgeschriebenen Hierarchierelation überzeugt sind, geben sie dieser doch den ihr gebührenden Raum."

- Abstract
- Documents usually have a content and a structure. The content refers to the text of the document, whereas the structure refers to how a document is logically organized. An increasingly common way to encode the structure is through the use of a mark-up language. Nowadays, the most widely used mark-up language for representing structure is the eXtensible Mark-up Language (XML). XML can be used to provide a focused access to documents, i.e. returning XML elements, such as sections and paragraphs, instead of whole documents in response to a query. Such focused strategies are of particular benefit for information repositories containing long documents, or documents covering a wide variety of topics, where users are directed to the most relevant content within a document. The increased adoption of XML to represent a document structure requires the development of tools to effectively access documents marked-up in XML. This book provides a detailed description of query languages, indexing strategies, ranking algorithms, presentation scenarios developed to access XML documents. Major advances in XML retrieval were seen from 2002 as a result of INEX, the Initiative for Evaluation of XML Retrieval. INEX, also described in this book, provided test sets for evaluating XML retrieval effectiveness. Many of the developments and results described in this book were investigated within INEX.

- Abstract
- As information becomes more ubiquitous and the demands that searchers have on search systems grow, there is a need to support search behaviors beyond simple lookup. Information seeking is the process or activity of attempting to obtain information in both human and technological contexts. Exploratory search describes an information-seeking problem context that is open-ended, persistent, and multifaceted, and information-seeking processes that are opportunistic, iterative, and multitactical. Exploratory searchers aim to solve complex problems and develop enhanced mental capacities. Exploratory search systems support this through symbiotic human-machine relationships that provide guidance in exploring unfamiliar information landscapes. Exploratory search has gained prominence in recent years. There is an increased interest from the information retrieval, information science, and human-computer interaction communities in moving beyond the traditional turn-taking interaction model supported by major Web search engines, and toward support for human intelligence amplification and information use. In this lecture, we introduce exploratory search, relate it to relevant extant research, outline the features of exploratory search systems, discuss the evaluation of these systems, and suggest some future directions for supporting exploratory search. Exploratory search is a new frontier in the search domain and is becoming increasingly important in shaping our future world.

- Abstract
- We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a "memex" that Vannevar Bush proposed in his seminal article, "As We May Think." Faceted search plays a key role in this program. Faceted search addresses weaknesses of conventional search approaches and has emerged as a foundation for interactive information retrieval. User studies demonstrate that faceted search provides more effective information-seeking support to users than best-first search. Indeed, faceted search has become increasingly prevalent in online information access systems, particularly for e-commerce and site search. In this lecture, we explore the history, theory, and practice of faceted search. Although we cannot hope to be exhaustive, our aim is to provide sufficient depth and breadth to offer a useful resource to both researchers and practitioners. Because faceted search is an area of interest to computer scientists, information scientists, interface designers, and usability researchers, we do not assume that the reader is a specialist in any of these fields. Rather, we offer a self-contained treatment of the topic, with an extensive bibliography for those who would like to pursue particular aspects in more depth.
