摘要
针对现有本体学习方法中存在的问题进行改进,提出了由关系模式进行本体学习的若干映射规则。首先介绍了本体的形式化定义,然后对现有关系模式向本体转换的各种方法进行了总结,并分析其存在的问题。在此基础上提出了基于关系模式的本体学习映射规则,并通过实例分别进行了说明。最后对算法的语义覆盖度进行了评价。
The relational schema mapping rules to ontology learning was studied aiming the existing problem.Firstly the formalization definition of ontology was introduced.Then the existing relational schema converting to ontology methods were summarized and analyzed its existing problems.Based on this,the ontology mapping rule based on relational schema were introduced,and explained through example.Finally,the semantic coverage of algorithm is evaluated.
