- Abstract
- Das wachsende Informationsvolumen im WWW führt paradoxerweise zu einer immer schwierigeren Nutzung, das Finden und Verknüpfen von Informationen in einem unstrukturierten Umfeld wird zur Sisyphosarbeit. Hier versprechen Semantic-Web-Ansätze Abhilfe. Die Autoren beschreiben Technologien, wie eine semantische Integration verteilter Daten durch verteilte Ontologien erreicht werden kann. Diese Techniken sind sowohl für Forscher als auch für Professionals interessant, die z.B. die Integration von Produktdaten aus verteilten Datenbanken im WWW oder von lose miteinander verbunden Anwendungen in verteilten Organisationen implementieren sollen.

- Abstract
- Medien bedeuten Macht. Kann das Internet Bertelsmann, Time Warner und Rupert Murdoch gefährlich werden? Großunternehmen versuchen auch die neuen Medien zu kapitalisieren, doch im globalen, dezentralen Kommunikationsnetz gelten andere Spielregeln. Auf der Basis freier Software, die von jedem kostenlos verändert und kopiert werden kann, entstehen völlig neue Medienformen. Millionen von "Weblogs" genannten Online-Postillen ergänzen die klassische Medienlandschaft um unabhängige Stimmen. Erste Experimente mit cleveren Finanzierungsmodellen zeigen, dass auf dieser Basis auch echter Journalismus möglich ist. Gleichzeitig arbeiten Tausende von Freiwilligen an offenen Wissensdatenbanken wie der gigantischen Enzyklopädie Wikipedia. Eine Konvergenz von Wikis und Weblogs zeichnet sich ab. Massive Online-Zusammenarbeit in den Bereichen Nachrichten, Wissen, Kunst und Kultur scheint unausweichlich oder findet bereits statt. Das revolutionäre Potenzial des Internet, das erst übertrieben, dann belächelt wurde, nimmt Konturen an. Dieses Buch erfasst den aktuellen Stand der Entwicklung, wagt einen vorsichtigen Blick in die Zukunft und liefert das notwendige Grundwissen zur direkten Partizipation an der neuen Medienwelt.

Weisel): "Mit dem vorliegenden Handbuch will der Herausgeber, Prof. Dr. Dirk Lewandowksi von der Hochschule für Angewandte Wissenschaften Hamburg, nach eigenen Worten eine Lücke füllen. Er hat renommierte Autoren aus unterschiedlichen Fachcommunities aufgerufen, zu dem Thema "Suchmaschinen im Internet" ihre unterschiedlichen Perspektiven in Form von Übersichtsartikeln zusammenzuführen. So möchte er mit diesem Band den Austausch zwischen den Communities sowie zwischen Wissenschaftlern und Praktikern fördern. . . . Empfehlung Dem Handbuch "Internet-Suchmaschinen" wird eine breite Leserschaft aus Wissenschaft und Praxis des Suchens und Findens im Web gewünscht, es sollte bei allen Einrichtungen für die Ausbildung des Fachnachwuchses zum Repertoire gehören, um diesen kritisch an die Thematik heranzuführen. Das gedruckte Werk wird der Aktualität und dem Wandel in diesem sehr dynamischen Fachgebiet Tribut zollen müssen. Statt einer zeitnahen Zweitausgabe sei dem Herausgeber und dem Verlag hier der Weg der kontinuierlichen Ergänzung empfohlen: um die oben genannten fehlenden Beiträge, aber auch sich neu ententwickelnde Inhalte - in Form eines lebendigen Lehrbuches -auf der geeigneten elektronischen Plattform."

- Abstract
- Das Buch Semantic Web Grundlagen vermittelt als erstes deutschsprachiges Lehrbuch die Grundlagen des Semantic Web in verständlicher Weise. Es ermöglicht einen einfachen und zügigen Einstieg in Methoden und Technologien des Semantic Web und kann z.B. als solide Grundlage für die Vorbereitung und Durchführung von Vorlesungen genutzt werden. Die Autoren trennen dabei sauber zwischen einer intuitiven Hinführung zur Verwendung semantischer Technologien in der Praxis einerseits, und der Erklärung formaler und theoretischer Hintergründe andererseits. Nur für letzteres werden Grundkenntnisse in Logik vorausgesetzt, die sich bei Bedarf jedoch durch zusätzliche Lektüre und mit Hilfe eines entsprechenden Kapitels im Anhang aneignen lassen.Das Lehrbuch richtet sich primär an Studenten mit Grundkenntnissen in Informatik sowie an interessierte Praktiker welche sich im Bereich Semantic Web fortbilden möchten.

- Abstract
- Mit Suchmaschinenoptimierung. Professionelles Website-Marketing für besseres Ranking liefern Stefan Karzauninkat und Tom Alby einen sauberen Überblick über Grundlagen, Gründe, Maßnahmen und Zielsetzungen von suchmaschinenoptierten Websites. Essentielles Internet-Wissen auf dem aktuellen Stand. Karzauninkat und Alby widmen ihr Buch Entscheidern, Konzeptionern, Designern und Webmastern, die ihre Website, ob neu oder alt, im Gesamtzusammenhang des Internet sehen und verstehen wollen. Suchmaschinen sind und waren dabei schon immer ein wesentlicher Faktor, denn sie sind die Instanz, die eine Website und deren Informationen findet, wenn sie gesucht wird. Die Sucharbeit der Maschinen kann man ignorieren, behindern oder unterstützen -- wenn man weiß wie. Karzauninkat und Alby haben ihr Wissen praktisch erworben. Vor allem Karzauninkat kann zahlreiche Internetprojekt vorweisen, zu denen auch die bekannte und viel besuchte Suchmaschinen-Website www.suchfibel.de gehört. Ziel der beiden Autoren ist es, ein allgemeines Verständnis für die Such- und Gefundenwelt des Internet und dauerhafte und anhaltende Maßnahmen für die gefunden-werden-Bilanz sowie die Platzierung innerhalb der Liste der gefundenen Suchergebnisse zu vermitteln. Überzeugen, erklären und zeigen lautet die Devise: Am Anfang steht eine Einführung mit dem Titel "Wozu das Ganze". Argumentationsstoff und Fakten für den folgenden Aufwand. Darauf folgt die Website-Optimierung als Teil der Unternehmenskommunikation und dieses Kapitel zeigt auch einen Fokus der beiden: Verkaufen. Nun gut, welcher Zweck auch immer, die Mittel sind immer die gleichen. Als nächstes stellen sie Suchmaschinen und ihre Funktionsweise vor, bevor sie sich dann dem Kern ihres Buches widmen: die Optimierung zur Positionsverbesserung. Hier entschlüsseln sie die Bedeutung von Inhalt, erklären kurz die technischen Belange und zeigen wo es Probleme und Widerstände geben kann. Auch professionelle Dienstleister für die Website-Optimierung nehmen sie unter die Lupe. Zuletzt dann Suchmaschinenmarketing, laufende Maßnahmen zur Erfolgskontrolle und dann noch sechs kurze Fallbeispiele. Ebenso bieten sie ein Glossar und einen Anhang mit Server-Response-Codes, Agents und Meta-Tags sowie weiterführende Literatur und Weblinks. Übrigens steht den Druck-Käufern das gesamte Buch auch als eBook zur Verfügung! Suchmaschinenoptimierung ist ein guter, locker geschriebener und leicht zu lesender, vor allem aktueller Überblick mit einem Gespür für die Fragen und Bedürfnisse der Zielgruppe von Entscheider bis Webmaster. Wer Suchmaschinen-Verständnis ohne technische Überlastung sucht, liest hier zufrieden.

- 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
- Das Internet mit seinen ständig neuen Usern und seinem extremen Wachstum bringt viele neue Herausforderungen mit sich. Aufgrund dieses Wachstums bedienen sich die meisten Leute der Hilfe von Suchmaschinen um Inhalte innerhalb des Internet zu finden. Suchmaschinen nutzen für die Beantwortung der User-Anfragen Information Retrieval Techniken. Problematisch ist nur, dass traditionelle Information Retrieval (IR) Systeme für eine relativ kleine und zusammenhängende Sammlung von Dokumenten entwickelt wurden. Das Internet hingegen unterliegt einem ständigen Wachstum, schnellen Änderungsraten und es ist über geographisch verteilte Computer verteilt. Aufgrund dieser Tatsachen müssen die alten Techniken erweitert oder sogar neue IRTechniken entwickelt werden. Eine Suchmaschine die diesen Herausforderungen vergleichsweise erfolgreich entgegnet ist Google. Ziel dieser Arbeit ist es aufzuzeigen, wie Suchmaschinen funktionieren. Der Fokus liegt dabei auf der Suchmaschine Google. Kapitel 2 wird sich zuerst mit dem Aufbau von Suchmaschinen im Allgemeinen beschäftigen, wodurch ein grundlegendes Verständnis für die einzelnen Komponenten geschaffen werden soll. Im zweiten Teil des Kapitels wird darauf aufbauend ein Überblick über die Architektur von Google gegeben. Kapitel 3 und 4 dienen dazu, näher auf die beiden Komponenten Crawler und Indexer einzugehen, bei denen es sich um zentrale Elemente im Rahmen von Suchmaschinen handelt.

Schweibenz): "Der Titel des Buches verspricht, dass es möglich sei, Web-Sites nicht nur barrierefrei, sondern auch attraktiv zu gestalten. Dieses Versprechen lösen Angie Radtke und Michael Charlier mit einer DemoWeb-Site für die fiktive Gemeinde BadSeendorf (Internet, URL http://www.badseendorf.de) ein. Dort werden einander zwei Versionen gegenübergestellt, wobei der Ausgangspunkt ein barrierebehaftetes Design ist, das durch eine barrierearme Version ersetzt wird. Diese beiden Beispiele wären für sich genommen bereits sehr hilfreich bei der Auseinandersetzung mit dem Thema Barrierefreiheit. In Kombination mit dem zugehörigen Buch haben Radtke und Charlier eine umfassende Einführung geschaffen, die sowohl für die eigenständige Einarbeitung in die Thematik als auch für die Verwendung in der Lehre sehr geeignet ist. In einem knappen theoretisch ausgerichteten Grundlagenteil werden Fragen behandelt wie beispielsweise was Barrierefreiheit ist und wem sie nützt, warum Zugänglichkeit und ansprechendes Design kein Widerspruch sind und welche gesetzlichen Vorgaben gelten. Im Mittelpunkt des umfangreichen Praxisteils steht die genannte Web-Site der fiktiven Gemeinde Bad-Seendorf. Ausgehend von dem barrierebehafteten Design werden an konkreten Beispielen die Probleme bestimmter Nutzergruppen analysiert, zu denen neben den üblicherweise dargestellten Betroffenen auch die Altersgruppe 50plus zählt, die häufig vernachlässigt wird. Weiterhin wird in einzelnen Kapiteln eine Analyse von Barrieren durchgeführt, sowie Maßnahmen zur gezielten Vermeidung von Zugangsblockaden und Zugangserschwernissen aufgezeigt, wobei auch auf multimediale Inhalte und Sonderfälle wie PDF, Flash, und Videos in Deutscher Gebärdensprache eingegangen wird. Eine kurze Beschreibung des Einsatzes von Content-Management-Systemen für barrierefreie Web-Angebote legt den Schwerpunkt auf die Systeme Joomla! und TYPO3.
