摘要

[目的/意义] 为解决现有网页文本缺乏起源标注的问题,提出一种借助PROV本体发现相似网页文本起源关系的方法。[方法/过程] 通过聚类算法、自动语义标注和关联数据构建等技术的综合应用,结合PROV-POL溯源模型,检测网页文本实体的演变过程,实现文本级和属性级两级溯源方案。[结果/结论] 实验验证了借助语义网技术和数据溯源模型实现网页文本数据溯源的可行性,但实验过程中聚类算法的召回率有待提高。

Abstract

[Purpose/significance] To solve the problem for lacking of provenance metadata in existing web page, we put forward a method of automatic annotation.[Method/process] By clustering algorithm, automatic semantic annotation and linked data technology, combined with the PROV-POL data provenance model, the derivation of the Web page text entities are detected, through implementing the text level and attribute level data provenance structure.[Result/conclusion] Tests show that the semantic web technology and PROV model used to get the data provenance of web page text is feasible. The recall rate of clustering algorithm we applied needs to be improved. This method has a promising practical value for Web provenance.
