摘　　要：由于手工构建本体的失误或本体学习方法的缺陷，本体构建过程易造成本体关系集合中存在冗余，导致本体应用时的不一致和效率低下。本文分析了冗余的本体关系，得出偏序关系易出现冗余现象。基于哈斯图的形成过程，研究了一种消除偏序关系冗余的方法。该方法适用于消除由偏序关系的自反性和传递性所导致的冗余关系。为验证本文方法的有效性，处理了wine本体。实验结果表明，该方法在约柬的范围内有效。Due to the errors coming from the manual ontology building process or the defects of ontology learning methods, redundant ontology relations emerge and lead to inconsistencies and low efficiency. This paper analyzes characteristics of redundant relations and figures out that redundancies may occur frequently in partial order relations. Based on the formation of Hasse diagrams, the paper proposes an approach of eliminating redundant ontology relations, which are caused by the reflexivity and transitivity of partial orders. An OWL ontology, the wine ontology, is processed to illustrate the proposed approach. Experiments show that the approach is effective in a constraint range.
