| 摘 要： | 为了有效地在Web上进行数据信息的提取,实现Web数据的清理与集成,针对发布批量格式化数据的网页类型,提出了利用XML和JTidy自动从Web页面批量提取数据信息的方法.根据该类网页的特点,基于开发一种通用程序的思想,对页面标签结构进行分析与分类,讨论了识别数据元素和对数据元素进行分组等提取过程中的难点,在此基础上建立了总体扫描与提取的算法.实验结果表明了批量提取信息方法的可行性与有效性.

| Abstract: | To extract data information from web effectively and implement web data purification and integration, the approach that automatically extract interested batch data from web pages is presented using XML and JTidy tools.Targeted on the specific web and a general processing idea, page structure is analyzed and classified.The main difficulties in design that are identifying and labeling data element, are discussed and the algorithms of general scanning and extracting are constructed.Finally, a case study of ext... |
