Ontology-Based Knowledge Management In ODSS

Knowledge management is an important content for organizational decision support system. It provides the functions of knowledge acquisition, knowledge sharing and knowledge reuse for ODSS. Because of the different comprehensions of knowledge between individuals, there are many problems, which need to solve, in ODSS's knowledge management.To avoid the diversity and inconsistent expression of organizational knowledge, Ontology is introduced to define the domain semantic common senses. This research of the model of organization knowledge management is guided and realized by building the multiple ontologies system. The main contents of this dissertation are as follow :1. This paper presents the concept of organizational decision support system, the development situations and the application domains.2. The concepts of knowledge management and the structure and function of knowledge management system are discussed. Also, this paper introduces the definition and the development of Ontology, and then brings forward the steps of building the domain ontology.3. Based on the features of ODSS's structure, the approach of constructing multiple ontologies system is described by using the common and special features of organization decision knowledge. The knowledge management tasks are processed by the guidance of the knowledge management meta-ontology and the task ontology, which are in the main ontology of multiple ontologies system. The way of managing the ontologies is discussed subsequently.4. By integrating the multiple ontologies system and the ODSS's features, which are beyond levels and domains, a framework of knowledge management model, which is based on Ontology, is put forward. The framework reaches the parallelizability and reconstruction and configuration of knowledge management by building different knowledge management models to process knowledge extraction and knowledge retrieval. Based on these,...
