Abstract

Within dynamic organizations, information systems often fail to adapt to changing requirements and structures. The book presents a different view of IS provision, based on end-user information systems construction, as a means of avoiding many of the recognized problems. Adopting a philosophy of constructivism, emphasizing psychological and social factors in information construction, the authors examine different types of systems across natural and social sciences

Abstract

This 5th ed. has been heavily revised and partly rewritten. It comprises 5 parts: (1) Theory of information retrieval systems (covering derived indexing, printed indexes and database access systems as well as sematics and syntax); (2) Precoordinate indexing systems (covering subject headings, notation, alphabetical index, OPACs); (3) Precoordinate indexing languages (covering the DDC, UDC, BC, CC, LCC, LCSH and shorter lists of subject headings); (4) Postcoordinate indexing languages; (5) The future (digital libraries).

Abstract

Das sogenannte "systemische Herangehen" wird häufig als eine Gegenströmung gegen die zunehmende Aufspaltung der Wissenschaft in hochspezialisierte Bereiche dargestellt, was zu einem Zusammenbruch der Kommunikation zwischen Spezialisten führt. Schon das Wort "System" setzt ein Bewußtsein der Wechselwirkung der Teile voraus, wodurch ein "Ganzes" seine eigenen existentiellen Eigenschaften unabhängig von denen der Teile erhält. Befürworter der Allgemeinen Systemtheorie haben es sich zur Aufgabe gemacht, hinreichend allgemeine Prinzipien zu suchen, die sich auf viele verschiedene Zusammenhänge anwenden lassen: physi kalische, biologische, psychologische und soziale. Aus diesem Grunde arbeiten allgemeine Systemtheoretiker in vielen unterschiedlichen Wissenschaftsbereichen ebenso wie unter Philosophen, Ingenieuren und Unternehmenspraktikern. Deshalb gibt es Befürworter einer intellektuellen Integration auf einer anderen Ebene. Wie integriert man aber die Integrationalisten? Dies Buch bemüht sich, die Aufgaben der Allgemeinen Systemtheorie aus verschiedenen Gesichtspunkten zu formulieren. Angefangen von dem Standpunkt eines Mathematikers, der nach formalen mathematischen Analogien zwischen ganz unterschiedlichen Inhalten als der am meisten versprechenden Grundlage einer Integration sucht, bis zum Standnunkt des Philosophen, der den Begriff eines "lebenden Systems" über die auffälligsten Beispiele - individuelle Lebewesen - zu erweitern sucht. Der vorliegende Band gliedert sich um die hauptsächlichen Begriffe der Allgemeinen Systemtheorie. Im zweiten Kapitel dient das abstrakte mathematische Modell als ein Brennpunkt für die Integration von Phänomenen, die inhaltlich verschieden, ihrer Struktur nach einander ähnlich sind. Im dritten Kapitel wird die Grundlage der subjektiven Wahrnehmung von "Systemheit" mit Nachdruck auf die Wahrnehmung und Zuschreibung von Realität von "Ganzheiten" untersucht. Kapitel vier und fünf behandeln jeweils Organisation und Zielgerichtetheit, Eigenschaften, die besonders lebenden Systemen (einschließlich gesellschaftlichen Systemen) zugeschrieben werden. Kapitel sechs ist ein Überblick über die Anwendungen der Vorstellungen der Allgemeinen Systemtheorie mit besonderem Nachdruck auf Erweiterung der elementaren Begriffe von Ursachen und Wirkun gen. Daß eine Ursache mehrere Wirkungen haben und eine Wirkung die Folge vieler Ursachen sein mag, wird von jedem zugegeben. Dennoch wird bei der Erledigung praktischer Aufgaben und bei Versuchen einer Problemlösung diese Binsenwahrheit häufig aus den Augen verloren. Erst die dramatischen Manifestationen (häufig verheerender) Nebenwirkungen von Lösungsversuchen haben die Unzulänglichkeit massiv angewandter "technischer Notlösungen" in den Mittelpunkt öffentlicher Aufmerksamkeit gerückt. Dieses neue Bewußtsein des grundlegenden Zusammenhanges von allem mit allem anderen ist wahrscheinlich das wichtigste "praktische" Ergebnis des systemischen Herangehens gewesen.

Abstract

For courses in Expert Systems, Knowledge-Based Systems, Artificial Intelligence or Decision Support Systems, this book embodies the fact that expert systems now extend beyond the field of computer science into such areas as engineering and business. It offers a comprehensive understanding of expert systems and shows their application to real world problems. The material is presented in such a way that the student needs no previous experience in computers or computer programming. The book addresses all of the topics necessary to understand, build, validate, and implement expert systems - with many examples, exercises, and problems. A working version of EXSYS - a microcomputer-based expert systems software program - is packaged with the text.
