- Abstract
- Informationstechnik wird im vorliegenden Werk umfassend als diejenige Technik verstanden, die der Speicherung, dem Transport und der Verarbeitung von Information dient. Im Gegensatz zu jeder sonstigen Technik, die ausschließlich vom Erkenntnisfundament der Physik getragen wird, benötigt die Informationstechnik zusätzlich ein nichtphysikalisches Erkenntnisfundament, welches man Informatik nennen kann, falls man diese nicht als die "Wissenschaft des Programmierens", sondern als die "Wissenschaft von den interpretierten Systemen" versteht. Die Machbarkeit informationstechnischer Systeme beruht auf der Formalisierbarkeit der Strukturen, die man bei der Analyse des menschlichen Kommunizierens und logischen Schließens findet. Diese informationellen Strukturen werden in den drei Kapiteln des Buches behandelt. Zuerst wird der Informationsbegriff und sein Umfeld - mit den Schwerpunkten Sprache und Logik - besprochen. Anschließend folgt die Betrachtung des Systembegriffs und seines Umfeldes, wobei die Modellierung im Mittelpunkt steht. Im letzten Kapitel werden die vorgestellten Begriffswelten zur umfassenden Begriffswelt der informationellen Systeme mit den Schwerpunkten Kommunikation und Programmierung integriert. Aus den Besprechungen: "...ein ungewöhnliches Lesevergnühen mit einem Technik-"Erzähler" hohen Ranges. Alle wesentlichen Grundphänomene der Informatik, die unmittelbaren Bezug auf die zugeordnete Elektrotechnik (die Informationstechnik) haben, werden ausführlich erörtert und ... auch für fachliche Laien schön verständlich abgehandelt. ... trotz der Eleganz der Präsentation ein sehr ernsthaftes Lehrbuch. ..."

- Abstract
- Einführung in den Umgang mit dem interaktiven Datennetz sowie dessen Hilfsprogramme (z.B. FTP, Telnet, Usenet). Von der Menge der Internet-Einführungen hebt sich dieser auf deutsche Verhältnisse abgestimmte Text angenehm ab. Er ist kurz, gut gedruckt und übersichtlich strukturiert und erklärt dem Einsteiger auch die Möglichkeiten, kostengünstig ins Internet zu gelangen. Technisches wird nur gestreift, wo es für die Nutzung der vielfältigen Möglichkeiten des Netzes unumgänglich ist. Natürlich werden die Hilfsmittel und -Programme wie FTP, Telnet und Usenet, Archie, Gopher und WWW eingehend beschrieben.

- Abstract
- Engst here provides the cure for the Internet disenfranchised. Packed into nearly 1000 pages is an exhaustive overview of the Internet and its history, tools, and resources. A great deal of the book is devoted to differing connections to the Internet and their advantages and disadvantages, plus important Internet software. Internet aficionados might argue with Engst on some of the details, but this book and its comprehensive collections of facts, rather than factoids, provides a real service to Internet novices. Even if you don't systematically read the text, you'll find the collection of Internet tools on disk invaluable. This is one of the best places to start Internetting.

- Abstract
- As the World Wide Web continues to expand, it becomes increasingly difficult for users to obtain information efficiently. Because most search engines read format languages such as HTML or SGML, search results reflect formatting tags more than actual page content, which is expressed in natural language. Spinning the Semantic Web describes an exciting new type of hierarchy and standardization that will replace the current "Web of links" with a "Web of meaning." Using a flexible set of languages and tools, the Semantic Web will make all available information - display elements, metadata, services, images, and especially content - accessible. The result will be an immense repository of information accessible for a wide range of new applications. This first handbook for the Semantic Web covers, among other topics, software agents that can negotiate and collect information, markup languages that can tag many more types of information in a document, and knowledge systems that enable machines to read Web pages and determine their reliability. The truly interdisciplinary Semantic Web combines aspects of artificial intelligence, markup languages, natural language processing, information retrieval, knowledge representation, intelligent agents, and databases.

- Abstract
- Der Autor geht der Frage nach dem Einfluß der Normung auf die Kommunikationstechnik und ihrer sozialen Akzeptanz nach. Hierzu zeigt er die Strukturen der Normungsprozesse und der Gremien insbesondere in Europa auf. Am Beispiel der Normen zu elektronische Postsystemen führt er auf, wie weit die Normung in diese Systeme hineinreicht und welche kommunikationsrechtlichen Probleme damit verbunden sind

- Abstract
- Das Werk behandelt die aktuellen Entwicklungen zur inhaltlichen Erschließung von Informationsquellen im Internet. Topic Maps, semantische Modelle vernetzter Informationsressourcen unter Verwendung von XML bzw. HyTime, bieten alle notwendigen Modellierungskonstrukte, um Dokumente im Internet zu klassifizieren und ein assoziatives, semantisches Netzwerk über diese zu legen. Neben Einführungen in XML, XLink, XPointer sowie HyTime wird anhand von Einsatzszenarien gezeigt, wie diese neuartige Technologie für Content Management und Information Retrieval im Internet funktioniert. Der Entwurf einer Abfragesprache wird ebenso skizziert wie der Prototyp einer intelligenten Suchmaschine. Das Buch zeigt, wie Topic Maps den Weg zu semantisch gesteuerten Suchprozessen im Internet weisen.

- Abstract
- Suchmaschinen sind die neuen »Gatekeeper« im Internet. Sie kanalisieren unsere Aufmerksamkeit und haben entscheidenden Einfluss darauf, welche Inhalte wie zugänglich sind. Ohne sie sind Informationen im Netz nur schwer auffindbar. Allerdings: Nur wenige Nutzer wissen, wie man Suchmaschinen optimal bedient und wie sie funktionieren. Sie sind anfällig für Manipulationen (»Spamming«) und verschaffen auch ungewollt Zugang zu illegalen und jugendgefährdenden Inhalten. Wie können Suchmaschinen trotzdem ihrer Verantwortung als zentrale Informationssortierer gerecht werden? Eine groß angelegte Untersuchung der Bertelsmann Stiftung stellt diese Beobachtungen auf eine wissenschaftliche Basis. Eine Nutzerbefragung, ein Laborexperiment und ein Leistungsvergleich geben Aufschluss über Image, Bedienerfreundlichkeit und Qualität von Suchmaschinen. Aus dieser Analyse entwickeln die Autoren einen Code of Conduct für Suchmaschinenbetreiber, der einen möglichst objektiven und transparenten Zugang zu Informationen im Netz garantieren soll. Das Buch ist dreigeteilt: Im ersten umfangreichen Teil (bis Seite 490) werden, nach einer Einführung in die Suchmaschinenproblematik und ihr Umfeld, Qualität und Nutzung erforscht: Nach der Marktanalyse der deutschsprachigen Suchdienste werden ausgewählte einem Leistungsvergleich unterzogen. Der Gefährdung von Kindern und Jugendlichen widmet sich das Kapitel Problemanalyse. Wie erfolgreich Spamversuche die Suchergebnisse beeinflussen können, wird anschließend dargestellt. Den Kenntnissen und Einstellungen von Nutzern von Suchdiensten widmet sich ein ausführliches Kapitel. Nutzungshäufigkeit, Suchprozesse und Vorgehensweisen sind detailliert untersucht worden. Die Ergebnisse der Laborexperimente liefern konkrete Einsichten, auf über 100 Seiten verständlich beschrieben. In Kapitel 6 werden die angewandten Methoden ausführlich erläutert. Das angefügte Glossar könnte ausführlicher sein. Der zweite Teil appelliert an die gesellschaftliche Verantwortung der deutschen Suchdienstbetreiber, indem ein Code of Conduct für Suchmaschinen entworfen wird. Im dritten Teil wird auf die Entwicklungen in der Suchmaschinenlandschaft eingegangen, die sich durch Firmenübernahmen und die Monopolstellung von Google ergeben haben.

- Abstract
- In this collection of nearly 50 articles written by librarians, computer specialists, and other information professionals, the reader finds 10 chapters, each devoted to a problem or a side effect that has emerged since the introduction of the Internet: control over selection, survival of the book, training users, adapting to users' expectations, access issues, cost of technology, continuous retraining, legal issues, disappearing data, and how to avoid becoming blind sided. After stating a problem, each chapter offers solutions that are subsequently supported by articles. The editor's comments, which appear throughout the text, are an added bonus, as are the sections concluding the book, among them a listing of useful URLs, a works-cited section, and a comprehensive index. This book has much to recommend it, especially the articles, which are not only informative, thought-provoking, and interesting but highly readable and accessible as well. An indispensable tool for all librarians.

- Rez. in: JASIST 55(2004) no.11, S.1025-1026 (D.E. Agosto): ""Did you ever feel as though the Internet has caused you to lose control of your library?" So begins the introduction to this volume of over 50 articles, essays, library policies, and other documents from a variety of sources, most of which are library journals aimed at practitioners. Volume editor Block has a long history of library service as well as an active career as an online journalist. From 1977 to 1999 she was the Associate Director of Public Services at the St. Ambrose University library in Davenport, Iowa. She was also a Fox News Online weekly columnist from 1998 to 2000. She currently writes for and publishes the weekly ezine Exlibris, which focuses an the use of computers, the Internet, and digital databases to improve library services. Despite the promising premise of this book, the final product is largely a disappointment because of the superficial coverage of its issues. A listing of the most frequently represented sources serves to express the general level and style of the entries: nine articles are reprinted from Computers in Libraries, five from Library Journal, four from Library Journal NetConnect, four from ExLibris, four from American Libraries, three from College & Research Libraries News, two from Online, and two from The Chronicle of Higher Education. Most of the authors included contributed only one item, although Roy Tennant (manager of the California Digital Library) authored three of the pieces, and Janet L. Balas (library information systems specialist at the Monroeville Public Library in Pennsylvania) and Karen G. Schneider (coordinator of lii.org, the Librarians' Index to the Internet) each wrote two. Volume editor Block herself wrote six of the entries, most of which have been reprinted from ExLibris. Reading the volume is muck like reading an issue of one of these journals-a pleasant experience that discusses issues in the field without presenting much research. Net Effects doesn't offer much in the way of theory or research, but then again it doesn't claim to. Instead, it claims to be an "idea book" (p. 5) with practical solutions to Internet-generated library problems. While the idea is a good one, little of the material is revolutionary or surprising (or even very creative), and most of the solutions offered will already be familiar to most of the book's intended audience.
Unlike muck of the professional library literature, Net Effects is not an open-aimed embrace of technology. Block even suggests that it is helpful to have a Luddite or two an each library staff to identify the setbacks associated with technological advances in the library. Each of the book's 10 chapters deals with one Internet-related problem, such as "Chapter 4-The Shifted Librarian: Adapting to the Changing Expectations of Our Wired (and Wireless) Users," or "Chapter 8-Up to Our Ears in Lawyers: Legal Issues Posed by the Net." For each of these 10 problems, multiple solutions are offered. For example, for "Chapter 9-Disappearing Data," four solutions are offered. These include "Link-checking," "Have a technological disaster plan," "Advise legislators an the impact proposed laws will have," and "Standards for preservation of digital information." One article is given to explicate each of these four solutions. A short bibliography of recommended further reading is also included for each chapter. Block provides a short introduction to each chapter, and she comments an many of the entries. Some of these comments seem to be intended to provide a research basis for the proposed solutions, but they tend to be vague generalizations without citations, such as, "We know from research that students would rather ask each other for help than go to adults. We can use that (p. 91 )." The original publication dates of the entries range from 1997 to 2002, with the bulk falling into the 2000-2002 range. At up to 6 years old, some of the articles seem outdated, such as a 2000 news brief announcing the creation of the first "customizable" public library Web site (www.brarydog.net). These critiques are not intended to dismiss the volume entirely. Some of the entries are likely to find receptive audiences, such as a nuts-and-bolts instructive article for making Web sites accessible to people with disabilities. "Providing Equitable Access," by Cheryl H. Kirkpatrick and Catherine Buck Morgan, offers very specific instructions, such as how to renovate OPAL workstations to suit users with "a wide range of functional impairments." It also includes a useful list of 15 things to do to make a Web site readable to most people with disabilities, such as, "You can use empty (alt) tags (alt="') for images that serve a purely decorative function. Screen readers will skip empty (alt) tags" (p. 157). Information at this level of specificity can be helpful to those who are faced with creating a technological solution for which they lack sufficient technical knowledge or training.
Some of the pieces are more captivating than others and less "how-to" in nature, providing contextual discussions as well as pragmatic advice. For example, Darlene Fichter's "Blogging Your Life Away" is an interesting discussion about creating and maintaining blogs. (For those unfamiliar with the term, blogs are frequently updated Web pages that ]ist thematically tied annotated links or lists, such as a blog of "Great Websites of the Week" or of "Fun Things to Do This Month in Patterson, New Jersey.") Fichter's article includes descriptions of sample blogs and a comparison of commercially available blog creation software. Another article of note is Kelly Broughton's detailed account of her library's experiences in initiating Web-based reference in an academic library. "Our Experiment in Online Real-Time Reference" details the decisions and issues that the Jerome Library staff at Bowling Green State University faced in setting up a chat reference service. It might be useful to those finding themselves in the same situation. This volume is at its best when it eschews pragmatic information and delves into the deeper, less ephemeral libraryrelated issues created by the rise of the Internet and of the Web. One of the most thought-provoking topics covered is the issue of "the serials pricing crisis," or the increase in subscription prices to journals that publish scholarly work. The pros and cons of moving toward a more free-access Web-based system for the dissemination of peer-reviewed material and of using university Web sites to house scholars' other works are discussed. However, deeper discussions such as these are few, leaving the volume subject to rapid aging, and leaving it with an audience limited to librarians looking for fast technological fixes."

- Abstract
- Glister's 16 chapters, plus an appendix of Internet providers, takes readers on a dizzying view of Internet. In the first quarter of the book, you pick up a global perspective on Internet, while in the second, you learn how to use Internet for your own personal devices with mail, FTP (file transfer protocol), and telnet. In the second half, you master how to take advantage of Internet resources from electronic journals to WAIS databases. Overall, Gilster commendably organizes Internet facts and experiences well, making them accessible to both beginner and old-timer alike. If there's only one book on Internet that you can afford on your shelf, this is your best choice.

- Abstract
- Why doesn't your home page appear on the first page of search results, even when you query your own name? How do other Web pages always appear at the top? What creates these powerful rankings? And how? The first book ever about the science of Web page rankings, "Google's PageRank and Beyond" supplies the answers to these and other questions and more. The book serves two very different audiences: the curious science reader and the technical computational reader. The chapters build in mathematical sophistication, so that the first five are accessible to the general academic reader. While other chapters are much more mathematical in nature, each one contains something for both audiences. For example, the authors include entertaining asides such as how search engines make money and how the Great Firewall of China influences research. The book includes an extensive background chapter designed to help readers learn more about the mathematics of search engines, and it contains several MATLAB codes and links to sample Web data sets. The philosophy throughout is to encourage readers to experiment with the ideas and algorithms in the text. Any business seriously interested in improving its rankings in the major search engines can benefit from the clear examples, sample code, and list of resources provided. It includes: many illustrative examples and entertaining asides; MATLAB code; accessible and informal style; and complete and self-contained section for mathematics review.

- 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.
