摘　　要：本体日益受到人们的关注。随着知识的增加,领域本体会变得异常庞大。对于特定用户,其知识水平和工作需要仅涉及该本体的一小部分。因此,对于该用户,根据他所拥有的知识来理解整个领域本体是不现实的,并会对本体的应用带来障碍。文章提出了一种针对特定用户的本体提取和简化算法,根据用户给定的概念集和相应的导出关系集,形成一个既包含用户关注的概念集,又符合原本体知识体系和结构特征的个性化视图。Since an ontology is a formal, explicit specification of a shared conceptualization, it will get incredibly huge in size and complex in structure as the work evolves. Meanwhile, for specific agents or groups, their job requirement may only deal with a small part of the ontology. This mismatch between overall requirement and specific desirability will hinder the application of ontology. There have been some researches on the extraction of sub-ontology from a global one. But most of them require not only human interference but also an ontology engineer that should have sufficient background knowledge. This paper proposes an algorithm focusing on the ontology extraction and simplification for specific agents.
