Abstract

Semantische Technologien werden als die Zukunft menschlichen Wissens gehandelt. Gleichzeitig haftet ihnen immer noch etwas von Geheimwissenschaften an. Dieses Kompendium bietet eine auch für Quereinsteiger verständliche Einführung in das Thema. Es präsentiert verschiedene semantische Techniken, von automatischen Text-Mining-Verfahren bis hin zu komplexen Ontologien, mit einem Schwerpunkt auf semantischen Netzen. Das Kompendium semantische Netze versetzt seine Leser in die Lage zu beurteilen, was semantische Technologien leisten können, indem es die anschauliche Erklärung der Grundprinzipien mit Anwendungsbeispielen aus der Unternehmenspraxis und Kosten-Nutzen-Erwägungen ergänzt. Im praktischen Teil lernt der Leser semantische Netze zu modellieren. Eine Fülle von Beispielen, über 80 Abbildungen sowie zahlreiche Übungen erhöhen den praktischen Nutzen des Werkes.
