摘　　要：在本体学习过程中,随着本体中概念的增多,必然存在概念及概念间关系的冗余,如果不及时对本体进行优化,本体中的关键信息就会淹没于冗余的概念关系之间。针对这种情况,基于FCA(形式概念分析)理论提出一种本体优化算法。应用FCA中概念格相关知识建立本体原型,通过消除本体原型层次关系中的冗余,达到优化的目的。实验结果表明,本体原型经过优化,消除了层次关系中的冗余,使概念间的关系更加清晰,核心内容更加突出。In the ontology building process,the critical information of ontology is submerged in the redundancy of the concept and the relationship between the concepts with the concepts’ rising,if it is not optimized.This paper presents a dynamic optimization algorithm of ontology based on Formal Concept Analysis（FCA）.With the knowledge of building ontology prototype based on FCA theory,through removing the redundant concepts and the relation of them,it achieves the purpose of optimization,so as to eliminate redundant in ontology,make the relationship between the concepts be more clearly,the critical information key content be more prominent.
