(Java algorithm (1) - cosine similarity calculation string similarity rate 1. Functional requirements: recently, we are doing crawler technology to crawl news from major related websites and store it in company data. There is a technical point here, that is, how to ensure that the news you have crawled is not stored in the database if there are similar news or the same news. (Because some websites will quote news from other websites, or,)

java算法（1）---余弦相似度计算字符串相似率
1、功能需求：最近在做通过爬虫技术去爬取各大相关网站的新闻，储存到公司数据中。
这里面就有一个技术点，就是如何保证你已爬取的新闻，再有相似的新闻或者一样的新闻，那就不存储到数据库中。
（因为有网站会去引用其它网站新闻，或者把其它网站新闻拿过来稍微改下内容就发布到自己网站中）。
2、解析方案：最终就是采用余弦相似度算法，来计算两个新闻正文的相似度。现在自己写一篇博客总结下。
