摘　　要： 分析描述逻辑本体构建的重要性和研究现状.针对描述逻辑本体构建中本体的完备性问题,研究属性探索算法在描述逻辑本体构建中的应用,分析目前运用属性探索算法构建本体时假设专家必须具备全部领域知识的不足,研究在领域专家不具备全部领域知识情况下的完备描述逻辑本体构建.在描述背景下给出描述逻辑本体完备性的定义,设置描述背景下的不完备背景,构造一种在不完备背景下领域专家不能判断属性集合间的蕴含关系的描述逻辑本体构建算法.该算法可与领域专家交互获取蕴含知识从而构建本体知识库,并且证明利用该方法构建的本体是完备本体. The importance and current research progress of the description logics ontologies are analyzed, especially the application of attribute exploration in the construction of description logics ontologies according to the completeness of the description logics ontologies. The insufficiency in the knowledge that domain experts are supposed to have in using attribute exploration to construct the description logics ontologies is discussed. The construction of complete description logics ontologies under which circumstances domain experts do not have all the knowledge required in the domain is discussed as well. Moreover, a definition for the completeness of description logics ontologies under the description contexts is provided, and the incomplete contexts under the description contexts are set. An algorithm of constructing the description logics ontologies is constructed under the condition that domain experts are unable to define the attribute implications between those attribute sets. The proposed algorithm is used to acquire an embodying knowledge and then construct the knowledge base. And it can be proved that the description logics ontologies constructed by the proposed method is a complete one.
