在產業協同合作環境下，智慧型文件/知識管理機制將可協助企業體有效管理複雜之產業知識、文件與交易資訊。如欲使知識庫或文件庫成為企業經營的重要資產，文件內容與權限管理為箇中一項要務。本論文以包含主要與次要關鍵字等內容之關鍵字結構表達知識文件的重要意涵，並以一套四階段法則有系統地根據關鍵字結構進行知識文件權限推論；文中並以一案例驗證本方法論之可行性。整體而言，此研究成果可提供知識工程師一套適用於協同合作架構之知識內容與權限管理技術。

　　　　　The intelligent document and knowledge management mechanism is required for efficient management over the sophisticated knowledge, documents and transaction information induced in the business collaboration environment. In order to establish the knowledge or document repository as an enterprise asset, one of the critical issues is the document content and authority management. In this paper, the key contents of a document are represented as the knowledge ontology consisting of major and minor keywords. Since a decision support approach for document authority determination is required to systematically determine knowledge accessibility, this paper proposes a four-phase reasoning approach for document authority management using keyword ontology. Authority of the target knowledge can be automatically determined on the basis of the keyword correlation with the existing documents. A demonstration case is also provided to illustrate feasibility of the approach. Generally, the approach can provide the knowledge engineer or administrator an applicable solution for efficient knowledge/document content and authority management under the collaborative commerce architecture.
