An Information Model for Intelligent Information Systems

This paper deals with some fundamental problems of intellectualized computer information systems. The general properties of information expressions in information systems are induced from a number of example sentences. The concepts of information element and information structure have been introduced and a dualistic model for information expression has been worked out with several propositions suggested. To improve the adaptability of information systems for different user requirements, both the principle of knowledge searching in AI and the mechanism of model management in DSS are introduced into the design of information enquiry instead of using the conventional way by pure data management. An information processing model is formulated as a tetrad (Model name, Information set, Information conversion functions, Procedure), in which the techniques of knowledge reasoning, model calculating and data processing are utilized. Five essential information conversion functions are described and a practical dynamic algorithm for modelling the information processing procedure is given.
