google停用词列表

无论是英文还是中文，页面内容中都会有一些出现频率很高，却对内容没有任何影响的词，如“的”、“地”、“得”之类的助词，“啊”、“哈”、“呀”之类的感叹词，“从而”、“以”、“却”之类的副词或介词。这些词被称为停止词，因为它们对页面的主要意思没什么影响。英文中的常见停止词有the，a，an，to，of等。为节省存储空间和提高搜索效率，搜索引擎在索引页面或处理搜索请求时会自动忽略某些字或词，这些字或词即被称为Stop Words(停用词)。文档中如果大量使用停用词容易对页面中的有效信息造成噪音干扰，所以搜索引擎在运算之前都要对所索引的信息进行消除噪音的处理。

搜索引擎停用词常见有以下两类：

1、这些词应用十分广泛，在Internet上随处可见，比如“Web”一词几乎在每个网站上均会出现，对这样的词搜索引擎无法保证能够给出真正相关的搜索结果，难以帮助缩小搜索范围，同时还会降低搜索的效率；

2、这类就更多了，包括了语气助词、副词、介词、连接词等，通常自身并无明确的意义，只有将其放入一个完整的句子中才有一定作用，如常见的“的”、“在”之类。

举个例子来说，象“IT技术”，虽然其中的“IT”从我们的本意上是指“Information Technology”，事实上这种缩写也能够为大多数人接受，但对搜索引擎来说，此“IT”不过是“it”，即“它”的意思，这在英文中是一个极其常见同时意思又相当含混的词，在大多数情况下将被忽略。我们在IT技术点评中保留“IT”更多地面向“人”而非搜索引擎，以求用户能明了IT技术点评网站涉及的内容限于信息技术，虽然从SEO的角度这未必是最佳的处理方式。
