摘要

许多Web站点包含使用公共模板动态生成的大型页面集。通过语义标注从这些页面中提取的结构化数据对信息系统具有重要的价值。我们提出了一个系统,即自动从这些Web页面中提取数据值并对数据模式进行注释。在大量真实的Web页面集合上的实验评估表明,我们的算法正确地提取了数据并标注了数据模式。

Data extraction and annotation for dynamic Web pages
Many Web sites contain large sets of pages generated dynamically using a common template. The structured data extracted from these pages with semantic annotation are valuable for information system. We proposed a system, ADeaD, to automatically extract data values from these Web pages and annotate the data schema. Experimental evaluation on a lot of real Web page collections indicates our algorithm correctly extracted data and annotated the data schema.
