Abstract

Ontologies have been developed and investigated for quite a while now in artificial intelligente and natural language processing to facilitate knowledge sharing and reuse. More recently, the notion of ontologies has attracied attention from fields such as intelligent information integration, cooperative information systems, information retrieval, electronic commerce, and knowledge management. The author systematicaliy 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 Internet-based electronic commerce. In the second part of the book, the author presents a more technical view an emerging Web standards, like XML, RDF, XSL-T, or XQL, allowing for structural and semantic modeling and description of data and information.

Footnote

Sämtliche Beiträge sind von hohem Niveau und bieten anspruchsvolle Lektüre. Verallgemeinert formuliert, fragen sie nach der Verknüpfung zwischen dem breiteren Kontext des Warum und Wie der menschlichen Informationssuche und den technischen bzw. sonstigen Randbedingungen, die die Interaktion zwischen Benutzern und Systemen bestimmen. Natürlich liegt hier kein Hand- oder Lehrbuch vor, sodass man - fairerweise - nicht von einer systematischen Behandlung dieses Themenbereichs oder einem didaktischen Aufbau ausgehen bzw. derlei erwarten darf. Das Buch bietet jedenfalls einen guten und vielfältigen Einstieg und Einblick in dieses interessante Forschungsgebiet. Fachlich einschlägige und größere allgemeine Bibliotheken sollten es daher jedenfalls in ihren Bestand aufnehmen. Schon die Rezension des oben zitierten zweiten Buches des Herausgeber-Duos Spink-Cole enthielt einen kritischen Hinweis auf das dortige Sachregister. Der vorliegende Band erfordert noch stärkere Nerven, denn der hier als "Index" bezeichnete Seitenfüller spottet geradezu jeder Beschreibung, umso mehr, als wir uns in einem informationswissenschaftlichen Kontext befi nden. Was soll man denn tatsächlich mit Einträgen wie "information" anfangen, noch dazu, wenn dazu über 150 verschiedene Seitenzahlen angegeben werden? Ähnlich verhält es sich mit anderen allgemeinen Begriffen wie z.B. "knowledge", "model", "tasks", "use", "users" - allesamt mit einer gewaltigen Menge von Seitenzahlen versehen und damit ohne Wert! Dieses der Leserschaft wenig dienliche Register ist wohl dem Verlag anzulasten, auch wenn die Herausgeber selbst seine Urheber gewesen sein sollten. Davon abgesehen wurde wieder einmal ein solide gefertigter Band vorgelegt, der allerdings wegen seines hohen Preis eher nur institutionelle Käufer ansprechen wird."
