Rez. in: JASIST 56(2005) no.2, S.215-216 (A. Heath): "What is small, thoroughly organized, and easy to understand? Well, it's Heting Chu's latest book an information retrieval. A very welcome release, this small literary addition to the field (only 248 pages) contains a concise and weIl-organized discussion of every major topic in information retrieval. The often-complex field of information retrieval is presented from its origin in the early 1950s to the present day. The organization of this text is top-notch, thus making this an easy read for even the novice. Unlike other titles in this area, Chu's user-friendly style of writing is done an purpose to properly introduce newcomers to the field in a less intimidating way. As stated by the author in the Preface, the purpose of the book is to "present a systematic, thorough yet nontechnical view of the field by using plain language to explain complex subjects." Chu has definitely struck up the right combination of ingredients. In a field so broad and complex, a well-organized presentation of topics that don't trip an themselves is essential. The use of plain language where possible is also a good choice for this topic because it allows one to absorb topics that are, by nature, not as easy to grasp. For instance, Chapters 6 and 7, which cover retrieval approaches and techniques, an often painstaking topic for many students and teachers is deftly handled with the use of tables that can be used to compare and contrast the various models discussed. I particularly loved Chu's use of Koll's 2000 article from the Bulletin of the American Society for Information Science to explain subject searching at the beginning of Chapter 6, which discusses the differences between browsing and searching. The Koll article uses the task of finding a needle in a haystack as an analogy.
Chu's intent with this book is clear throughout the entire text. With this presentation, she writes with the novice in mind or as she puls it in the Preface, "to anyone who is interested in learning about the field, particularly those who are new to it." After reading the text, I found that this book is also an appropriate reference book for those who are somewhat advanced in the field. I found the chapters an information retrieval models and techniques, metadata, and AI very informative in that they contain information that is often rather densely presented in other texts. Although, I must say, the metadata section in Chapter 3 is pretty basic and contains more questions about the area than information. . . . It is an excellent book to have in the classroom, an your bookshelf, etc. It reads very well and is written with the reader in mind. If you are in need of a more advanced or technical text an the subject, this is not the book for you. But, if you are looking for a comprehensive, manual that can be used as a "flip-through," then you are in luck."

Cole ist kurz vor ihrem im letzten Heft der Mitteilungen der VÖB besprochenen zweiten Buch erschienen. Er wendet sich an Informationswissenschaftler, Bibliothekare, Sozialwissenschaftler sowie Informatiker mit Interesse am Themenbereich Mensch-Computer-Interaktion und präsentiert einen Einblick in die aktuelle Forschung zum kognitiv orientierten Information Retrieval. Diese Richtung, die von der Analyse der Informationsprobleme der Benutzer und deren kognitivem Verhalten bei der Benutzung von Informationssystemen ausgeht, steht in einem gewissen Kontrast zum traditionell vorherrschenden IR-Paradigma, das sich auf die Optimierung der IR-Systeme und ihrer Effizienz konzentriert. "Cognitive information retrieval" oder CIR (natürlich geht es auch hier nicht ohne ein weiteres Akronym ab) ist ein interdisziplinärer Forschungsbereich, der Aktivitäten aus Informationswissenschaft, Informatik, Humanwissenschaften, Kognitionswissenschaft, Mensch-Computer-Interaktion und anderen informationsbezogenen Gebieten inkludiert.
