全面准确地标注Deep Web数据是实现Deep Web数据集成系统的关键问题,然而现有的DeepWeb数据语义标注方法还不能很好地解决这一问题.提出一种基于CPN网络的Deep Web数据语义标注方法,通过提取属性值的基本特征,采用CPN网络实现Deep Web数据语义标注.同时,采取了一种有效的方法准确获取Deep Web结果页面中的属性值,为语义标注奠定了良好的基础.与同类成果相比,基于CPN网络的Deep Web数据语义标注方法提高了语义标注的准确率及召回率.
Accurately annotating Deep Web data is a key issue to realize Deep Web data integration system, however, the existing DeepWeb data semantic annotation method can not solve this problem well.This paper proposes a Deep Web data semantic annotation method based on CPN network , By extracting the basic characteristics of attribute values, using CPN network to realize Deep Web data semantic annotation.At the same time, an effective method is used to obtain the attribute value in Deep Web result page accurately, which lays a good foundation for semantic annotation. Compared with the results, Deep Web data semantic annotation based on CPN network improves the accuracy and recall of semantic annotation.
