    在前一篇文章中,分析出了一个实现的具体思路,主要是利用中文分词、Unicode编码来解决无法使用mysql的全文索引进行中文搜索的问题,本篇文章中将详细介绍中文分词的实现方法。

    首先是解决中文分词,中文分词就是将一句中文进行拆分,得到一个个单一的词,如“高薪诚聘注册造价工程师”这句话,经过分词处理后,会得到“高薪 诚聘 注册 造价 工程师”一个个单一的词。网上对中文分词的技术有很多介绍,有很好的开源产品和服务接口。但是结合我们产品用的主流开发语言是PHP,所以还是偏向选择了一个支持PHP模块扩展的开源中文分词系统scws,便于直接整合进项目中进行调用。

    至于如何安装scws和生成php模块,不是本文介绍的重点,请参考官方文档,香港服务器租用,有很详细的介绍。

    安装好scws并生成php的模块后,美国空间,就可以直接调用scws提供的api进行中文分词了,下面是一个用php调用scws进行中文分词的方法,可以用来测试中文分词。

    如果安装成功,运行以下代码,将得到“高薪 诚聘 注册 造价 工程师”的输出。
