Abstract

The scale of web site design has grown so that what was once comparable to decorating a room is now comparable to designing buildings or even cities. Designing sites so that people can find their way around is an ever-growing challenge as sites contain more and more information. In the past, Information Architecture for the World Wide Web has helped developers and designers establish consistent and usable structures for their sites and their information. This edition of the classic primer on web site design and navigation is updated with recent examples, new scenarios, and new information on best practices. Readers will learn how to present large volumes of information to visitors who need to find what they're looking for quickly. With topics that range from aesthetics to mechanics, this valuable book explains how to create interfaces that users can understand easily.

Abstract

Für Webseiten ist, wie für alle interaktiven Anwendungen vom einfachen Automaten bis zur komplexen Software, die Benutzerfreundlichkeit von zentraler Bedeutung. Allerdings wird eine sinnvolle Benutzung von Informationsangeboten im World Wide Web häufig durch "cooles Design" unnötig erschwert, weil zentrale Punkte der Benutzerfreundlichkeit (Usability) vernachlässigt werden. Durch Usability Evaluation kann die Benutzerfreundlichkeit von Webseiten und damit auch die Akzeptanz bei den Benutzern verbessert werden. Ziel ist die Gestaltung von ansprechenden benutzerfreundlichen Webangeboten, die den Benutzern einen effektiven und effizienten Dialog ermöglichen. Das Buch bietet eine praxisorientierte Einführung in die Web Usability Evaluation und beschreibt die Anwendung ihrer verschiedenen Methoden.

Abstract

Indexing consists of both novel and more traditional techniques. Cutting-edge indexing techniques, such as automatic indexing, ontologies, and topic maps, were developed independently of older techniques such as thesauri, but it is now recognized that these older methods also hold expertise. Indexing describes various traditional and novel indexing techniques, giving information professionals and students of library and information sciences a broad and comprehensible introduction to indexing. This title consists of twelve chapters: an Introduction to subject readings and theasauri; Automatic indexing versus manual indexing; Techniques applied in automatic indexing of text material; Automatic indexing of images; The black art of indexing moving images; Automatic indexing of music; Taxonomies and ontologies; Metadata formats and indexing; Tagging; Topic maps; Indexing the web; and The Semantic Web.

Abstract

"The Semantic Web is an extension of the current Web in which information is given well defined meaning, better enabling computers and people to work in cooperation." - Tim Berners Lee, "Scientific American", May 2001. This authoritative guide shows how the "Semantic Web" works technically and how businesses can utilize it to gain a competitive advantage. It explains what taxonomies and ontologies are as well as their importance in constructing the Semantic Web. The companion web site includes further updates as the framework develops and links to related sites.

Rez. Amazon: "Die Autoren bezeichnen das Buch im Vorwort als strategischen Führer für Führungskräfte und Entwickler die sich einen Überblick über das Semantic Web und die dahinter stehende Vision machen wollen. Genau diesem Anspruch wird das Buch auch absolut gerecht. Die ersten beiden Kapitel beschreiben die Vision sowie die Möglichkeiten, die sich durch den Einsatz der in den nachfolgenden Kapiteln beschriebenen Techniken bieten. Die Autoren schaffen es anhand vieler praktischer Szenarien (die zwar teilweise meiner Einschätzung nach schon noch in einiger Zukunft liegen, aber die große Vision des ganzen schön vergegenwärtigen) sehr schnell den Leser für die Technik zu begeistern und mehr darüber wissen zu wollen. Die nachfolgenden Kapitel beschreiben die Techniken auf den verschiedenen semantischen Ebenen von XML als Basis für alles weitere, über Web Services, RDF, Taxonomies und Ontologies. Den Autoren gelingt es die beschriebenen Techniken so kurz und prägnant zu erklären, dass sich der Leser danach zumindest ein Bild über die Techniken an sich, sowie über deren komplexes Zusammenspiel machen kann. Auch für Entwickler würde ich das Buch empfehlen, da es einen sehr guten Einstieg in viele doch sehr neue Techniken bietet mit vielen Verweisen auf weitere Literatur. Alles in allem ein sehr gelungenes Buch, das es trotz relativ geringem Umfangs schafft, einen guten Überblick über dieses komplexe Thema zu vermitteln."

Abstract

The author systematically introduces the notion of ontologies to the non-expert reader and demonstrates in detail how to apply this conceptual framework for improved intranet retrieval of corporate information and knowledge and for enhanced Internetbased electronic commerce. He also describes ontology languages (XML, RDF, and OWL) and ontology tools, and the application of ontologies. In addition to structural improvements, the second edition covers recent developments relating to the Semantic Web, and emerging web-based standard languages.

Rez. in: Online-Mitteilungen 2006, Nr.87, S.21-22 (M. Buzinkay):"Web 2.0 ist in aller Munde, Social Software und interaktive Web-Anwendungen boomen. Welche Technologie steckt dahinter, und wie lässt sich diese für individuelle Zwecke einsetzen? Diese Frage beantwortet Johannes Gamperl in "AJAX. Web 2.0 in der Praxis", weiches im Galileo Verlag erschienen ist. Das Zauberwort hinter Web 2.0 heißt AJAX. AJAX heißt "asynchron javascript and xml" und deutet an, woraus diese neue Programmier-Technik besteht: aus bereits vorhandenen und gut eingeführten Sprachen wie JavaScript und XML. Die Grundlagen sind nicht neu, doch die kreative Art ihrer Verwendung macht sie zur Zukunftstechnologie im Web schlechthin. Mit AJAX lassen sich Daten im Hintergrund und ohne ein neuerliches Laden einer Webseite übertragen. Das hat wesentliche Vorteile, denn so können Webseiten fortlaufend und interaktiv aktualisiert werden. Die Hauptbestandteile von AJAX sind neben XML und Javascript noch Cascading Style Sheets, das Document Object Model und XHTML. Das Buch vermittelt auf rund 400 Seiten Einblicke in die fortgeschrittene JavaScript Programmierung im Hinblick auf AJAX und das Web. Schritt für Schritt werden Beispiele aufgebaut, Techniken erläutert und eigene Kreationen gefördert. Allerdings ist das Buch kein Einsteigerbuch. Es wendet sich dezidiert an Programmierer, die über entsprechende Erfahrung mit JavaScript und XML verfügen. Die Kernthemen des Buches beinhalten - die Grundlagen des Document Object Model - die dynamische Bearbeitung von StyleSheet Angaben - den Zugriff auf XML-Daten über JavaScript - die Einführung in die Client/Server-Kommunikation - diverse JavaScript Bibliotheken Ergänzt werden diese Themen durch eine Reihe von Anwendungsbeispielen, die übersichtlich entwickelt und beschrieben werden. Eine CD mit dem Code liegt dem Buch bei. Weitere Unterstützung bieten diverse WebQuellen des Verlags und des Autors. Bekannte Beispiele für in AJAX programmierte Anwendungen sind Google Maps und Yahoo! Maps. Diese interaktiven Landkarten ermöglichen ein Heranzoomen, ein Sich-Bewegen auf Landkarten über Geo-Positioning; Satellitenbilder können eingeblendet werden. Über eine Schnittstelle (API) können externe Entwickler weitere Anwendungen auf Basis dieser Karten entwickeln, so z.B. ein Tankstellen-Netz mit den aktuellen Spritpreisen oder nutzergenerierten Reiserouten inklusive Entfernungsmessung."

Abstract

With the proliferation of huge amounts of (heterogeneous) data on the Web, the importance of information retrieval (IR) has grown considerably over the last few years. Big players in the computer industry, such as Google, Microsoft and Yahoo!, are the primary contributors of technology for fast access to Web-based information; and searching capabilities are now integrated into most information systems, ranging from business management software and customer relationship systems to social networks and mobile phone applications. Ceri and his co-authors aim at taking their readers from the foundations of modern information retrieval to the most advanced challenges of Web IR. To this end, their book is divided into three parts. The first part addresses the principles of IR and provides a systematic and compact description of basic information retrieval techniques (including binary, vector space and probabilistic models as well as natural language search processing) before focusing on its application to the Web. Part two addresses the foundational aspects of Web IR by discussing the general architecture of search engines (with a focus on the crawling and indexing processes), describing link analysis methods (specifically Page Rank and HITS), addressing recommendation and diversification, and finally presenting advertising in search (the main source of revenues for search engines). The third and final part describes advanced aspects of Web search, each chapter providing a self-contained, up-to-date survey on current Web research directions. Topics in this part include meta-search and multi-domain search, semantic search, search in the context of multimedia data, and crowd search. The book is ideally suited to courses on information retrieval, as it covers all Web-independent foundational aspects. Its presentation is self-contained and does not require prior background knowledge. It can also be used in the context of classic courses on data management, allowing the instructor to cover both structured and unstructured data in various formats. Its classroom use is facilitated by a set of slides, which can be downloaded from www.search-computing.org.

Rez. in: JASIST 57(2006) no.14, S.1979-1980 (J.G. Williams): "The Introduction and Part I of this book presents the world of computing with a historical and philosophical overview of computers, computer applications, networks, the World Wide Web, and eBusiness based on the notion that the real world places constraints on the application of these technologies and without a formalized approach, the benefits of these technologies cannot be realized. The concepts of real world constraints and the need for formalization are used as the cornerstones for a building-block approach for helping the reader understand computing, networking, the World Wide Web, and the applications that use these technologies as well as all the possibilities that these technologies hold for the future. The author's building block approach to understanding computing, networking and application building makes the book useful for science, business, and engineering students taking an introductory computing course and for social science students who want to understand more about the social impact of computers, the Internet, and Web technology. It is useful as well for managers and designers of Web and ebusiness applications, and for the general public who are interested in understanding how these technologies may impact their lives, their jobs, and the social context in which they live and work. The book does assume some experience and terminology in using PCs and the Internet but is not intended for computer science students, although they could benefit from the philosophical basis and the diverse viewpoints presented. The author uses numerous analogies from domains outside the area of computing to illustrate concepts and points of view that make the content understandable as well as interesting to individuals without any in-depth knowledge of computing, networking, software engineering, system design, ebusiness, and Web design. These analogies include interesting real-world events ranging from the beginning of railroads, to Henry Ford's mass produced automobile, to the European Space Agency's loss of the 7 billion dollar Adriane rocket, to travel agency booking, to medical systems, to banking, to expanding democracy. The book gives the pros and cons of the possibilities offered by the Internet and the Web by presenting numerous examples and an analysis of the pros and cons of these technologies for the examples provided. The author shows, in an interesting manner, how the new economy based on the Internet and the Web affects society and business life on a worldwide basis now and how it will affect the future, and how society can take advantage of the opportunities that the Internet and the Web offer.
The book is organized into six sections or parts with several chapters within each part. Part 1, does a good job of building an understanding some of the historical aspects of computing and why formalization is important for building computer-based applications. A distinction is made between formalized and unformalized data, processes, and procedures, which the author cleverly uses to show how the level of formalization of data, processes, and procedures determines the functionality of computer applications. Part I also discusses the types of data that can be represented in symbolic form, which is crucial to using computer and networking technology in a virtual environment. This part also discusses the technical and cultural constraints upon computing, networking, and web technologies with many interesting examples. The cultural constraints discussed range from copyright to privacy issues. Part 1 is critical to understanding the author's point of view and discussions in other sections of the book. The discussion on machine intelligence and natural language processing is particularly well done. Part 2 discusses the fundamental concepts and standards of the Internet and Web. Part 3 introduces the need for formalization to construct ebusiness applications in the business-to-consumer category (B2C). There are many good and interesting examples of these B2C applications and the associated analyses of them using the concepts introduced in Parts I and 2 of the book. Part 4 examines the formalization of business-to-business (B2B) applications and discusses the standards that are needed to transmit data with a high level of formalization. Part 5 is a rather fascinating discussion of future possibilities and Part 6 presents a concise summary and conclusion. The book covers a wide array of subjects in the computing, networking, and Web areas and although all of them are presented in an interesting style, some subjects may be more relevant and useful to individuals depending on their background or academic discipline. Part 1 is relevant to all potential readers no matter what their background or academic discipline but Part 2 is a little more technical; although most people with an information technology or computer science background will not find much new here with the exception of the chapters on "Dynamic Web Pages" and "Embedded Scripts." Other readers will find this section informative and useful for understanding other parts of the book. Part 3 does not offer individuals with a background in computing, networking, or information science much in addition to what they should already know, but the chapters on "Searching" and "Web Presence" may be useful because they present some interesting notions about using the Web. Part 3 gives an overview of B2C applications and is where the author provides examples of the difference between services that are completely symbolic and services that have both a symbolic portion and a physical portion. Part 4 of the book discusses B2B technology once again with many good examples. The chapter on "XML" in Part 4 is not appropriate for readers without a technical background. Part 5 is a teacher's dream because it offers a number of situations that can be used for classroom discussions or case studies independent of background or academic discipline.
Each chapter provides suggestions for exercises and discussions, which makes the book useful as a textbook. The suggestions in the exercise and discussion section at the end of each chapter are simply delightful to read and provide a basis for some lively discussion and fun exercises by students. These exercises appear to be well thought out and are intended to highlight the content of the chapter. The notes at the end of chapters provide valuable data that help the reader to understand a topic or a reference to an entity that the reader may not know. Chapter 1 on "formalism," chapter 2 on "symbolic data," chapter 3 on "constraints on technology," and chapter 4 on "cultural constraints" are extremely well presented and every reader needs to read these chapters because they lay the foundation for most of the chapters that follow. The analogies, examples, and points of view presented make for some really interesting reading and lively debate and discussion. These chapters comprise Part 1 of the book and not only provide a foundation for the rest of the book but could be used alone as the basis of a social science course on computing, networking, and the Web. Chapters 5 and 6 on Internet protocols and the development of Web protocols may be more detailed and filled with more acronyms than the average person wants to deal with but content is presented with analogies and examples that make it easier to digest. Chapter 7 will capture most readers attention because it discusses how e-mail works and many of the issues with e-mail, which a majority of people in developed countries have dealt with. Chapter 8 is also one that most people will be interested in reading because it shows how Internet browsers work and the many issues such as security associated with these software entities. Chapter 9 discusses the what, why, and how of the World Wide Web, which is a lead-in to chapter 10 on "Searching the Web" and chapter 11 on "Organizing the Web-Portals," which are two chapters that even technically oriented people should read since it provides information that most people outside of information and library science are not likely to know.
Chapter 12 on "Web Presence" is a useful discussion of what it means to have a Web site that is indexed by a spider from a major Web search engine. Chapter 13 on "Mobile Computing" is very well done and gives the reader a solid basis of what is involved with mobile computing without overwhelming them with technical details. Chapter 14 discusses the difference between pull technologies and push technologies using the Web that is understandable to almost anyone who has ever used the Web. Chapters 15, 16, and 17 are for the technically stout at heart; they cover "Dynamic Web Pages," " Embedded Scripts," and "Peer-to-Peer Computing." These three chapters will tend to dampen the spirits of anyone who does not come from a technical background. Chapter 18 on "Symbolic Services-Information Providers" and chapter 19 on "OnLine Symbolic Services-Case Studies" are ideal for class discussion and students assignments as is chapter 20, "Online Retail Shopping-Physical Items." Chapter 21 presents a number of case studies on the "Technical Constraints" discussed in chapter 3 and chapter 22 presents case studies on the "Cultural Constraints" discussed in chapter 4. These case studies are not only presented in an interesting manner they focus on situations that most Web users have encountered but never really given much thought to. Chapter 24 "A Better Model?" discusses a combined "formalized/unformalized" model that might make Web applications such as banking and booking travel work better than the current models. This chapter will cause readers to think about the role of formalization and the unformalized processes that are involved in any application. Chapters 24, 25, 26, and 27 which discuss the role of "Data Exchange," "Formalized Data Exchange," "Electronic Data Interchange-EDI," and "XML" in business-to-business applications on the Web may stress the limits of the nontechnically oriented reader even though it is presented in a very understandable manner. Chapters 28, 29, 30, and 31 discuss Web services, the automated value chain, electronic market places, and outsourcing, which are of high interest to business students, businessmen, and designers of Web applications and can be skimmed by others who want to understand ebusiness but are not interested in the details. In Part 5, the chapters 32, 33, and 34 on "Interfacing with the Web of the Future," "A Disruptive Technology," "Virtual Businesses," and "Semantic Web," were, for me, who teaches courses in IT and develops ebusiness applications the most interesting chapters in the book because they provided some useful insights about what is likely to happen in the future. The summary in part 6 of the book is quite well done and I wish I had read it before I started reading the other parts of the book.
The book is quite large with over 400 pages and covers a myriad of topics, which is probably more than any one course could cover but an instructor could pick and choose those chapters most appropriate to the course content. The book could be used for multiple courses by selecting the relevant topics. I enjoyed the first person, rather down to earth, writing style and the number of examples and analogies that the author presented. I believe most people could relate to the examples and situations presented by the author. As a teacher in Information Technology, the discussion questions at the end of the chapters and the case studies are a valuable resource as are the end of chapter notes. I highly recommend this book for an introductory course that combines computing, networking, the Web, and ebusiness for Business and Social Science students as well as an introductory course for students in Information Science, Library Science, and Computer Science. Likewise, I believe IT managers and Web page designers could benefit from selected chapters in the book."

Rez. in: JASIST 58(2007) no.3, S.457-458 (A.M.A. Ahmad): "The concept of the semantic web has emerged because search engines and text-based searching are no longer adequate, as these approaches involve an extensive information retrieval process. The deployed searching and retrieving descriptors arc naturally subjective and their deployment is often restricted to the specific application domain for which the descriptors were configured. The new era of information technology imposes different kinds of requirements and challenges. Automatic extracted audiovisual features are required, as these features are more objective, domain-independent, and more native to audiovisual content. This book is a useful guide for researchers, experts, students, and practitioners; it is a very valuable reference and can lead them through their exploration and research in multimedia content and the semantic web. The book is well organized, and introduces the concept of the semantic web and multimedia content analysis to the reader through a logical sequence from standards and hypotheses through system examples, presenting relevant tools and methods. But in some chapters readers will need a good technical background to understand some of the details. Readers may attain sufficient knowledge here to start projects or research related to the book's theme; recent results and articles related to the active research area of integrating multimedia with semantic web technologies are included. This book includes full descriptions of approaches to specific problem domains such as content search, indexing, and retrieval. This book will be very useful to researchers in the multimedia content analysis field who wish to explore the benefits of emerging semantic web technologies in applying multimedia content approaches. The first part of the book covers the definition of the two basic terms multimedia content and semantic web. The Moving Picture Experts Group standards MPEG7 and MPEG21 are quoted extensively. In addition, the means of multimedia content description are elaborated upon and schematically drawn. This extensive description is introduced by authors who are actively involved in those standards and have been participating in the work of the International Organization for Standardization (ISO)/MPEG for many years. On the other hand, this results in bias against the ad hoc or nonstandard tools for multimedia description in favor of the standard approaches. This is a general book for multimedia content; more emphasis on the general multimedia description and extraction could be provided.
Semantic web technologies are explained, and ontology representation is emphasized. There is an excellent summary of the fundamental theory behind applying a knowledge-engineering approach to vision problems. This summary represents the concept of the semantic web and multimedia content analysis. A definition of the fuzzy knowledge representation that can be used for realization in multimedia content applications has been provided, with a comprehensive analysis. The second part of the book introduces the multimedia content analysis approaches and applications. In addition, some examples of methods applicable to multimedia content analysis are presented. Multimedia content analysis is a very diverse field and concerns many other research fields at the same time; this creates strong diversity issues, as everything from low-level features (e.g., colors, DCT coefficients, motion vectors, etc.) up to the very high and semantic level (e.g., Object, Events, Tracks, etc.) are involved. The second part includes topics on structure identification (e.g., shot detection for video sequences), and object-based video indexing. These conventional analysis methods are supplemented by results on semantic multimedia analysis, including three detailed chapters on the development and use of knowledge models for automatic multimedia analysis. Starting from object-based indexing and continuing with machine learning, these three chapters are very logically organized. Because of the diversity of this research field, including several chapters of recent research results is not sufficient to cover the state of the art of multimedia. The editors of the book should write an introductory chapter about multimedia content analysis approaches, basic problems, and technical issues and challenges, and try to survey the state of the art of the field and thus introduce the field to the reader.
The final part of the book discusses research in multimedia content management systems and the semantic web, and presents examples and applications for semantic multimedia analysis in search and retrieval systems. These chapters describe example systems in which current projects have been implemented, and include extensive results and real demonstrations. For example, real case scenarios such as ECommerce medical applications and Web services have been introduced. Topics in natural language, speech and image processing techniques and their application for multimedia indexing, and content-based retrieval have been elaborated upon with extensive examples and deployment methods. The editors of the book themselves provide the readers with a chapter about their latest research results on knowledge-based multimedia content indexing and retrieval. Some interesting applications for multimedia content and the semantic web are introduced. Applications that have taken advantage of the metadata provided by MPEG7 in order to realize advance-access services for multimedia content have been provided. The applications discussed in the third part of the book provide useful guidance to researchers and practitioners properly planning to implement semantic multimedia analysis techniques in new research and development projects in both academia and industry. A fourth part should be added to this book: performance measurements for integrated approaches of multimedia analysis and the semantic web. Performance of the semantic approach is a very sophisticated issue and requires extensive elaboration and effort. Measuring the semantic search is an ongoing research area; several chapters concerning performance measurement and analysis would be required to adequately cover this area and introduce it to readers."

Abstract

Das Internet und besonders das Web 2.0 sind ein Segen für die Meinungsfreiheit, so heißt es: Endlich können alle bestimmen, worüber diskutiert wird - nicht nur wenige Experten, Top-Journalisten und wortgewaltige Autoren, die das Meinungsmonopol für sich beanspruchen. Doch was haben wir uns da eingehandelt? Forumsbeiträge, die vor Dummheit und falschen Fakten strotzen, und an Idiotie kaum zu überbietende Videoclips bei YouTube. Es kommt noch schlimmer: - Politische Splitterparteien und verschrobene Wirrköpfe maskieren sich immer häufiger als harmlose Blogger, um demokratiefeindliche Hetzkampagnen zu verbreiten. Betroffene können sich kaum dagegen wehren. - Unternehmen betreiben auf subtile Weise "virales Marketing", um ihre Produkte von vermeintlich begeisterten Kunden empfehlen zu lassen. - Clevere Lobbyisten mischen sich unter falscher Identität in Diskussionen ein, um ihre fragwürdigen Interessen durchzusetzen. Wir befinden uns auf einem gefährlichen Irrweg, sagt Andrew Keen: Wo Halbwissen und blanke Lügen herrschen statt verlässlicher Information, da fehlt auch die Basis für vernünftige und tragfähige politische Entscheidungen, da ist unsere Kultur in ihren Grundfesten erschüttert. Ein scharf formuliertes Plädoyer gegen die absurden Auswüchse der großen Verdummungsmaschine, die sich Internet nennt.

Rez. in: FR, Nr.289 vom 10.12.2008, S.36: "Das Internet: Unser Fluch? - Schon Internet-Pionier Nicholas Negroponte erklärte das World Wide Web zu einem riesigen Müllhaufen, und dieser Befund dürfte durch die Entwicklung des Netzes eher bestätigt worden sein. Aber wie das so ist mit dem Müll: Für die einen ist es Abfall, andere suchen und finden meistens etwas, das sich zur Wiederverwer- tung eignet. Das muss Andrew Keen entgangen sein, obwohl der IT-Unternehmer (audiocafe.com), sich in der Materie auskennt. Aber das hindert ihn nicht, sich mit geradezu pietistischem Eifer wider den neu-bösen Feind zu wenden: den Blogger. Keen sieht im durch soziale Netzwerke und demokratische Teilhabe geprägten Web 2.0 nicht nur den "Kult des Amateurs" (so der Originaltitel, korrekt übersetzt), sondern sogar die "Vernichtung unserer Kultur". So richtig der eine oder andere Befund sein mag - etwa die Selbstbezüglichkeit vieler Slogger - er wird nicht richtiger durch penetrante Wiederholung. Falsch aber ist eine Behauptung wie die, dass Einträge bei Wikipedia (noch ein Lieblingsfeind Keens) nicht redigiert würden. Da hat sich einer in sein Bedürfnis nach werbewirksamer Polemik verrannt".
