随着Metaweb加入Google的消息放出，我们可以意识到Google更加重视关键字的相关性研究。根据Metaweb官方的自我介绍和FAQ，我们可以大概了解Metaweb拥有非语义上的关键字相关性筛选技术，简单的说就是不同人物，地点和事物背后所隐藏的一些共性，例如：我们搜索“斯瓦辛格”，这个对搜索引擎来说很好理解，但是如果我们搜索“加利福尼亚州州长，终结者，宇宙先生”，搜索引擎未必能很准确的判断我们的意图。

可以说，如果这种非语义的相关性搜索技术一旦成熟，这无疑又是搜索引擎的一大进步。另外，根据美国专利商标局的记录，Metaweb还拥有多项和搜索有关的专利技术，也许对我们猜测Google的新的发展方向有所帮助。（消息来源：SEO by the sea，中文翻译纯属个人理解，小心误导）
