Our research on knowledge management is rooted in the community perspective. We believe that knowledge systems should serve primarily to help people create and share new knowledge. But we also acknowledge the role of stable, structured and reliable information, both as a component of our systems and as a component of the organizations within which we work. The contribution of the paper is a fra...

This paper discusses the applications of Fuzzy Boolean Programming (FBP) problems for representing and reasoning with Propositional Knowledge. The use of the models provided by the FBP are proposed to answer imprecise questions in precisely stated KBS. Also, the advantages of using Fuzzy Boolean Programming instead of classical ones are presented in the framework of Propositional Knowledge.

The management of the integrity of intelligent systems relies on techniques to integrate the components and to manage the integrity of the knowledge-based systems components. A unified methodology integrates knowledge-based systems components with database components. Constraints are used to manage the integrity of knowledge. One class of knowledge constraints protect the integrity of knowledge...

This article makes an example of Beijing Future Advertising Corporation and explains its multi-dimension spiral model, which includes knowledge spiral, opportunity spiral and value spiral. The three spirals connect and promote mutually and push the development of the corporations' core competency. Based on the theoretical thinking of Beijing Future Advertising Corporation, the article illustrat...

Knowledge-based view (KBV) theory posits that the acquisition and use of relevant knowledge is key to understanding organizational performance. However, there is relatively little empirical evidence to support or refute several important propositions underlying KBV theory explanations of organizational performance. In particular, the extant literature has focused on individual technical and sci...

In 1991, the DARPA Knowledge Sharing Effort ([88], p. 37) envisioned a new way to build intelligent systems. It proposed the following: Building knowledge-based systems today usually entails constructing new knowledge bases from scratch. It could be instead done by assembling reusable components. System developers would then only need to worry about creating the specialized knowledge and reason...

In many knowledge-based systems the used knowledge is distributed among several knowledge sources. Knowledge maintenance of such systems has several challenges to be met. This paper gives a short overview of a maintenance approach using so-called Case Factories to maintain knowledge sources and considering the dependencies between these sources. Furthermore we present a concept how our maintena...
