Abstract

Class-tested and coherent, this textbook teaches information retrieval, including web search, text classification, and text clustering from basic concepts. Ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students. Slides and additional exercises are available for lecturers. - This book provides what Salton and Van Rijsbergen both failed to achieve. Even more important, unlike some other books in IR, the authors appear to care about making the theory as accessible as possible to the reader, on occasion including short primers to certain topics or choosing to explain difficult concepts using simplified approaches. Its coverage [is] excellent, the quality of writing high and I was surprised how much I learned from reading it. I think the online resources are impressive.

Abstract

Some web sites "work" and some don't. Good web site consultants know that you can't just jump in and start writing HTML, the same way you can't build a house by just pouring a foundation and putting up some walls. You need to know who will be using the site, and what they'll be using it for. You need some idea of what you'd like to draw their attention to during their visit. Overall, you need a strong, cohesive vision for the site that makes it both distinctive and usable. Information Architecture for the World Wide Web is about applying the principles of architecture and library science to web site design. Each web site is like a public building, available for tourists and regulars alike to breeze through at their leisure. The job of the architect is to set up the framework for the site to make it comfortable and inviting for people to visit, relax in, and perhaps even return to someday. Most books on web development concentrate either on the aesthetics or the mechanics of the site. This book is about the framework that holds the two together. With this book, you learn how to design web sites and intranets that support growth, management, and ease of use. Special attention is given to: * The process behind architecting a large, complex site * Web site hierarchy design and organization Information Architecture for the World Wide Web is for webmasters, designers, and anyone else involved in building a web site. It's for novice web designers who, from the start, want to avoid the traps that result in poorly designed sites. It's for experienced web designers who have already created sites but realize that something "is missing" from their sites and want to improve them. It's for programmers and administrators who are comfortable with HTML, CGI, and Java but want to understand how to organize their web pages into a cohesive site. The authors are two of the principals of Argus Associates, a web consulting firm. At Argus, they have created information architectures for web sites and intranets of some of the largest companies in the United States, including Chrysler Corporation, Barron's, and Dow Chemical.

VÖB 64(2011) H.1, S. 153-155 (K Niedermair): "Vor einigen Wochen war in der Wochenzeitung Die Zeit ein dreiseitiger Beitrag über die gerade 10 Jahre alt gewordene Wikipedia zu lesen, unter dem Titel "Das größte Werk der Menschen": Wie könnte Wikipedia dieses Prädikat verdienen? Wohl schon aufgrund der Quantitäten: Die freie Enzyklopädie Wikipedia ist, seit sie am 15. Jänner 2001 online ging, extrem gewachsen, es gibt Plattformen in den meisten Sprachen, mit sehr viel Content, am meisten natürlich in der englischsprachigen Version, nämlich über drei Millionen Beiträge, auch die deutschsprachige ist beachtlich vertreten mit ca. einer Million. Wikipedia ist zu einer wichtigen Informationsquelle geworden, im Alltag, im Beruf, im Lehr- und Wissenschaftsbetrieb, dies zeigen immer wieder Befragungen von Studierenden und Wissenschaftler/innen. Verdienstvoll ist Wikipedia auch, weil sie nicht auf Gewinn orientiert ist, auf Werbeeinnahmen verzichtet. Wikipedia lebt vom Idealismus unzähliger freiwilliger Mitarbeiter/innen, die nicht um Geld, sondern aus Freude an der Arbeit gemeinsam dem großen Ziel verpflichtet sind, Wissen zu sammeln, zu ordnen und bereitzustellen - und zwar kostenlos für alle zu jeder Zeit und an jedem Ort. Es ist wohltuend, dass dieses Programm einer universalen Enzyklopädia publico in der kommerzialisierten Wirklichkeit des Internet überleben konnte und dass Erfolg und Wachstum im Internet nicht immer mit Geld zu tun haben müssen, wie es Google, Facebook usw. nahelegen, deren Gründer bekanntlich inzwischen Milliardäre sind. Und Wikipedia ist insofern ein starkes Argument gegen die landläufige These, dass Information nur brauchbar ist, wenn sie etwas kostet: Qualitätssicherung von Information hängt nicht zwangsläufig mit ihrer Ökonomisierung zusammen. Tatsächlich ist Wikipedia inzwischen eine massive Konkurrenz für die herkömmlichen, kommerziell orientierten Lexika und Enzyklopädien.
