摘　　要：目前提出的从关系数据库中获取本体的方法主要关注主键之间的相关性,导致抽取的语义信息不全。本文提出一种将关系数据库向Flogic表示的本体转换的方法,该方法通过对主键、数据、属性相关性的综合分析,可以抽取出关系数据库中隐含的语义信息,如继承关系及优化结构。The existing approaches of extracting ontology from relational databases can only extract a small subset of semantics embedded within a relational database. In my opinion, the potential source of these problems lies in that the primary focus has been on analyzing key correlation. As an attempt to resolve the problems, we propose a novel approach, which is based on an analysis of key, data and attribute correlations, as well as their combination. Our approach allows the user to extract more semantics from the relational database, including inheritance and optimization structures.
