【摘要】 本体作为一种知识组织、表示和共享的模型,可以很好地应用在领域知识的管理和重用中。传统的本体创建从信息采集到本体的构建都需要大量的人工参与,工作量大且效率低下,所以我们需要研究一种自动化或者半自动化的构建本体的方法来提高本体的构建效率。由于关系数据库是一种普遍使用的数据存储方式,并且与本体直接存在着一定的内部关系,所以文章分析技术转移领域相关的关系数据库的数据模型,建立数据模型和本体的转换规则,利用这些规则将数据库模型转换成本体模型,将数据转换成本体实例,实现本体的自动构建。更多还原

【Abstract】 As a model of knology represention, orgnization and share,ontology can be well appliedin the field of knowledge management and reuse of. In the traditional method of ontology generation, so many people were used to paticipate in the work, which cause more jobs and lower efficiency. So we need an automatic or semiautomatic method to generate ontology to promote the efficency. Now, rational database is a most populate data storage mode,which hide the ralationship between rational database and ontology model. So we can analysis the data model and generate the transfer rules to get the ontology, and then, expend the ontology, so that we can realize the automatic ontology generation.更多还原
