Due to the lack of syntax structure of the information in web pages, especially in the semi-structure pages, the traditional natural language processing technology is not applicable to the web information extraction well. And web pages is recognized, explained and shown by browers and viewed by users, in which there is a lot of vison characters. So if the vision information in web pages can be used for information extraction, complex linguistic knowledge would be avoided.

由于Web页面的内容缺乏严格规范的语法结构，尤其是半结构化页面，所以传统的自然语言处理技术并不能很好地适用于Web信息抽取，另外Web页面被浏览器识别、解释和显示并供用户查看和理解，其中包含了大量的视觉特征，如果把Web页面的这种视觉信息应用于信息抽取，就可以避免使用复杂的语言学知识。
