Research On Some Key Technologies Of Knowledge Management Integrating Context

With the support from the item of National Nature Science Foundation of China (No.79970036): The Research on the Organization Mechanism, Model and Tool of the Knowledge Integration and the item of State 863 High-Tech R&D Program of China (No.2002AA414310): The Technologies of Knowledge Engineering and Knowledge Management for Enterprise Knowledge Innovation, the concept of context is explicitly introduced into Knowledge Management (KM) and the research on basic theories, methods, key technologies and system of Knowledge Management Integrating Context (KMIC) is conducted comprehensively and deeply in this dissertation to solve the problems and difficulties faced in the process of KM implementation in manufacturing enterprises. And the research achievements are put into practice combined with the digital project of a garment group and the information project of an auto parts group.In the 1st chapter, the research background of this dissertation is described. KM technologies and tools, context and its application in KM are reviewed and analyzed, and the main content and structure of this dissertation are given.In chapter 2, the basic theories and framework of KMIC are discussed. On the basis of the definition of knowledge, KM and context, the relation of context to knowledge and KM, and the benefits of introducing context into KM are analyzed systematically. The definition and goal of KMIC are clarified, and the framework of KMIC is builtIn chapter 3, after analyzing the requirements of the context integrated knowledge modeling, the Knowledge Integrating Context (KIC) model based on knowledge carriers, knowledge content and knowledge context is proposed. The modeling of knowledge carriers, knowledge content and knowledge context is studied comprehensively. The principles for context modeling and a multi-dimension context modeling method are proposed. To meet the needs of computer supported KIC model processing, the storage implementation of KIC model based on ontology is discussed.In the 4th chapter, the context identifying and acquiring technologies are studied systematically. A multi-granularity design for context is presented, and a method for identifying and acquiring context is put forward as well, which combines direct context identifying acquirement and indirect context associating and reasoning acquirement. The technical architecture of context identifying and acquiring is...
