This paper describes how Intel IT determined where an information overload problem existed, identified whom the problem impacted, and defined how it impacted them. We also recommend short- and long-term solutions to alleviate this information overload problem (AU) |

This paper introduces the development of multiple representations as a platform for learning design knowledge in relation to the situations within which it was recognised. The benefits of this approach derive from the fact knowledge is more useful when it is learned in relation to its situations and less useful when it is learned out of context. The situation is the way in which knowledge is located in relation on to its sumoundings. The situatedness of knowledge is constructed through learning which parts of the surroundings are in conjunction with it across different representations of a design composition. In order to learn the situatedness of desing knowledge a medium is needed to present the desing composition from different views, each of which allows for various situations to be encountered. What makes multiple representations useful in the context of situatedness is that they provide the opportunities for different and rich relationships among design knowledge to be constructed. This provides a system within which to learn from a number of representations in which the situatedness of knowledge can be discerned and learned. Architectural design compositions are chosen as a vehicle for the demostration of the concept of situatedness in designing because the discovery of relationships among parts of the desing composition is a fundamental task in designing. The paper shows how multiple representations could provide a platform for situated learning systems in designing. What kind of situated knowlwdge could be learned from some of the possible representations of an architectural desing composition is discussed. The regularities of relationships between desing knowlege and its situations are investigated. (AU) |

Weighted Factors Analysis (WeFA) has been proposed as a new approach for elicitation, representation, and manipulation of knowledge about agiven problem, generally at a high and strategic level. Central to this proposal is that a group of experts in the area of the problem can identify a hierarchy of factors with positive or negative influences on the problem outcome. The tangible output of WeFA is a directed weighted graph called a WeFA graph. This is a set of nodes denoting factorsthat can directly or indirectly influence an overall aim of the graph. The aim is also represented by a node. Each directed arc is a directinfluence of one factor on another. A chain of directed arcs indicates an indirect influence. The influences may be identified as either positive or negative. For example, sales and costs are two factors that influence the aim of profitability in an organization sales has a positive influence on profitability and costs has a negative influence on profitability. In addition, the relative significance of each influence is represented by a weight. In this paper, we develop Binary WeFA which is a variant of WeFA where the factors in the graph are restrictedto being either true or false. Imposing this restriction on a WeFA graph allows us to be more precise about the meaning of the graph and ofreasoning in it. Binary WeFA is a new proposal that provides a formalyet sufficiently simple language for logic-based argumentation for use by business people in decision-support and knowledge management. Whilst Binary WeFA is expressively simpler than other logic-based argumentation formalisms, it does incorporate a novel formalization of the notion of significance. (AU) |

As automation of business processes becomes more complex and encompasses less-structured domains, it becomes even more essential that the knowledge used by these processes is verified and accurate. Most application development is facilitated with software tools, but most business rules and expert systems are developed in environments that provide inadequate verification testing. This paper describes an emerging class of applications we refer to as Knowledge Base Management Systems (KBMS). The KMBS provides a full life-cycle environment for the development and verification of business rule and expert systems. We will present an overview of knowledge base verification, the KBMS life-cycle, and the architecture for a KBMS. We then describe building a small expert system in the KBMS, with emphasis on the verification testing at each stage. We conclude with a summary of the benefits of a KBMS. (AU) |
