    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.

    Rez. in: CD Info. 2003, H.10, S.12: "Der Aufwand bei der Internet-Recherche hat sich mit guten Suchmaschinen wie Google verringert. Trotzdem verbringt der Computeranwender eine Menge Zeit mit dem Öffnen und Schließen von Webseiten, die er nie benötigt hätte. Wer die Arbeitsweise und die Möglichkeiten von Google kennt, kann die Suche besser eingrenzen und gelangt oft direkter zur gewünschten Homepage. Der Google Pocket Guide erläutert die Funktionsweise des am meisten verwendeten Suchtools, gibt Tipps zur optimalen Nutzung und liefert gleich einige konkrete Beispiele für deren Verwendung. Neben den Optionen der Erweiterten Suche widmet sich das kleine Taschenbuch auch der Syntax der Website, sodass die Befehle direkt in die Suchmaske eingegeben werden können. Auch Zusatz-Features wie die Bildersuche, der Webkatalog, die Newsgroup-Datenbank sowie der seit Kurzem auch in deutscher Sprache verfügbare News-Bereich werden behandelt. Der Google Pocket Guide erläutert kurz und bündig die wichtigsten Techniken und hilft Zeit und Aufwand zu sparen. Der brandneue Titel ist derzeit leider nur in Englisch verfügbar."

    Abstract
    Bilal, in this third part of her Yahooligans! study looks at children's performance with self-generated search tasks, as compared to previously assigned search tasks looking for differences in success, cognitive behavior, physical behavior, and task preference. Lotus ScreenCam was used to record interactions and post search interviews to record impressions. The subjects, the same 22 seventh grade children in the previous studies, generated topics of interest that were mediated with the researcher into more specific topics where necessary. Fifteen usable sessions form the basis of the study. Eleven children were successful in finding information, a rate of 73% compared to 69% in assigned research questions, and 50% in assigned fact-finding questions. Eighty-seven percent began using one or two keyword searches. Spelling was a problem. Successful children made fewer keyword searches and the number of search moves averaged 5.5 as compared to 2.4 on the research oriented task and 3.49 on the factual. Backtracking and looping were common. The self-generated task was preferred by 47% of the subjects.
