| Summary: | 碩士 === 國立清華大學 === 工業工程與工程管理學系 === 91 === Owing to the wide applications of e-business solutions and cost ineffectiveness of the paper-based document management mechanism, electronic and systematic approaches for enterprise document management are required. To improve the efficiency and effectiveness of security management over the growing electronic documents, this research proposes a set of security reasoning models for e-knowledge management over the Internet. In these models, the document keyword extraction and document categorization algorithms are provided to extract the key attributes of the enterprise documents. According to the attributes, the reasoning models can be utilized to provide the document providers (or the system administrator of the document management system) with an initial security determination solution via the historical data related to user identity and document contents. Therefore the security management principles are constructed by incorporating the role and content models and working with the centralized knowledge management mechanism to ensure the consistency and security of enterprise documents. In addition, on the basis of the intelligent reasoning models, a web-based prototype system is implemented and a demonstration case is also provided to validate the effectiveness of the proposed technology. It is the attempt of this research that users from various organizations may share knowledge and documents efficiently with each other under the E-knowledge management platform.
