基于用户日志的本体进化

Ontology evolution based on userlog

本体作为语义网的基石,发挥着越来越重要的作用。本体进化的目的在于动态调整本体以适应环境的变化。从基于领域本体的用户日志出发,使用Aporior算法挖掘用户操作的频繁项集和频繁路径。通过对频繁项集和频繁路径的分析,得到了本体进化的辅助建议,并在实验中对该方法进行了实现和测试,实验结果证明该方法能有效地实现本体进化。

Ontology is the cornerstone of the semantic Web.It plays the more and more important role in the semantic Web.The purpose of ontology evolution is dynamically to adjust itself in the changing environment.The thesis start from the users log on domain ontology,used Aporior mining algorithms to get frequent and frequent users of the operating path.Through the analysis of frequent path,and get the advice of the ontology evolution and realize the method in experiments.The experiments prove the method is effective.
