过程:
1)先把一篇文章,按逗号分隔成一个一个短语
2)然后计算每个短语的字数
3)前两个>10个字的短语,我们拿出来在百度搜索下,计算百度搜索结果中,完整出现该短语的次数。
若一个文章被其他网站大量转载,那么随便提取该文章中一个短语,都能在百度搜索出完全重复的内容:
如果我们连续搜索两个短语,在百度搜索中,完全重复的结果很少,则可以一定程度代表该内容被其他站点大量转载的概率比较小,原创度较高
以上3个步骤,编写一个脚本来执行:
左列是文章ID,右列是两个短语,在百度搜索结果中完整出现的次数。次数越大,重复度越高,具体数值达到多少,自己定义。比如本渣一般将>=30%定位重复度比较高的,即搜索2个短语,20个搜索结果中,完整出现该短语的结果有>=6个
