| 摘 要： | XPATH在Web信息提取中起重要作用,但是这些XPATH规则通常要人工生成。文中讨论了在XPATH与基于文本上下文规则的信息提取方法结合的系统中如何归纳学习XPATH规则。生成的XPATH规则结构简单,可以为基于文本上下文的信息提取系统提供较为准确的信息定位。

| Abstract: | XPATH plays an important role in Web information extraction,but these XPATH rules usually generated by hand.Discusses about how to inductively learn XPATH rules used in an XPATH and text-context-based rules combined information extraction system.The generated rules have simple structure,and they can support as an accurate locator for text-context-based information extraction system. |
