Abstract

The World Wide Web is rapidly filling with more text than anyone could have imagined even a short time ago, but the task of isolating relevant parts of this vast information has become just that much more daunting. Richard Belew brings a cognitive perspective to the study of information retrieval as a discipline within computer science. He introduces the idea of Finding Out About (FDA) as the process of actively seeking out information relevant to a topic of interest and describes its many facets - ranging from creating a good characterization of what the user seeks, to what documents actually mean, to methods of inferring semantic clues about each document, to the problem of evaluating whether our search engines are performing as we have intended. Finding Out About explains how to build the tools that are useful for searching collections of text and other media. In the process it takes a close look at the properties of textual documents that do not become clear until very large collections of them are brought together and shows that the construction of effective search engines requires knowledge of the statistical and mathematical properties of linguistic phenomena, as well as an appreciation for the cognitive foundation we bring to the task as language users. The unique approach of this book is its even handling of the phenomena of both numbers and words, making it accessible to a wide audience. The textbook is usable in both undergraduate and graduate classes on information retrieval, library science, and computational linguistics. The text is accompanied by a CD-ROM that contains a hypertext version of the book, including additional topics and notes not present in the printed edition. In addition, the CD contains the full text of C.J. "Keith" van Rijsbergen's famous textbook, Information Retrieval (now out of print). Many active links from Belew's to van Rijsbergen's hypertexts help to unite the material. Several test corpora and indexing tools are provided, to support the design of your own search engine. Additional exercises using these corpora and code are available to instructors. Also supporting this book is a Web site that will include recent additions to the book, as well as links to sites of new topics and methods.

Abstract

This book discusses many of the key design issues for building search engines and emphazises the important role that applied mathematics can play in improving information retrieval. The authors discuss not only important data structures, algorithms, and software but also user-centered issues such as interfaces, manual indexing, and document preparation. They also present some of the current problems in information retrieval that many not be familiar to applied mathematicians and computer scientists and some of the driving computational methods (SVD, SDD) for automated conceptual indexing

Weitere Rez. in: ZfBB 53(2006) H.3/4, S.215-217 (M. Hollender): "Die Aversion des Präsidenten der Französischen Nationalbibliothek, Jean-Noël Jeanneney, gegen die Pläne von Google zur Massendigitalisierung kann nach der breiten Erörterung in der Tagespresse als zumindest in Grundzügen bekannt vorausgesetzt werden. Nunmehr liegt seine im März 2005 entstandene »Kampfschrift« (S.7) aktualisiert und mit einem Nachwort von Klaus-Dieter Lehmann versehen, auch in einer deutschen Übersetzung vor. So viel vorab: selten erhält man für 9,90 Euro so wenig und zugleich so viel: so viel Polemik, Selbstpreisgabe und Emphase und so wenig konkrete strategisch weiterführende Ideen. Dem Leser fällt vor allem der plumpe Antiamerikanismus, der dem gesamten Büchlein zugrunde liegt, über kurz oder lang unangenehm auf. Jeanneney moniert die »unvermeidliche amerikanische Ichbezogenheit« (S. 9). Wer aber mag es Google verdenken, sein Projekt zunächst mit angloamerikanischen Bibliotheken zu starten? Die Bereitschaft der britischen Boolean Library, ihre exzellenten Bestände vor 1900 von Google ebenfalls digitalisieren zu lassen, wird von Jeanneney im Stile einer Verschwörungstheorie kommentiert: »Wieder einmal wurde uns die altbekannte angloamerikanische Solidarität vorgeführt.« (S.19) Mit derselben Emphase könnte man sich darüber freuen, dass Google sich der Bestände hochbedeutender Forschungsbibliotheken versichert - nicht aber Jeanneney. Fazit: die »US-Dominanz, die mit einer mehr oder weniger bewussten Arroganz einhergeht«, bewirke, dass »alles, was der amerikanischen Weltsicht widerspricht, aussortiert« werde (S. 23). Wer derart voreingenommen wie Jeanneney an die Google-Pläne herangeht, verbaut sich selber die Chancen auf eine konstruktive und kooperative Lösung des Google-Problems. ...
