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.

Abstract

Knowledge and Inference discusses an important problem for software systems: How do we treat knowledge and ideas on a computer and how do we use inference to solve problems on a computer? The book talks about the problems of knowledge and inference for the purpose of merging artificial intelligence and library science. The book begins by clarifying the concept of ""knowledge"" from many points of view, followed by a chapter on the current state of library science and the place of artificial intelligence in library science. Subsequent chapters cover central topics in the artificial intelligence: search and problem solving, methods of making proofs, and the use of knowledge in looking for a proof. There is also a discussion of how to use the knowledge system. The final chapter describes a popular expert system. It describes tools for building expert systems using an example based on Expert Systems-A Practical Introduction by P. Sell (Macmillian, 1985). This type of software is called an ""expert system shell."" This book was written as a textbook for undergraduate students covering only the basics but explaining as much detail as possible.
