算法的选择一定要结合具体case的考虑,假设你的分类总数是固定的,那么就可以对已有的串做聚类,训练成模型,然后在新串来的时候分到最相似的聚类中;假设你的分类总数不固定,数据量也不大,就可以每次对所有串两两计算距离;数据量大的时候两两计算就要考虑性能的开销,选择运算量小一些的距离度量如local sensitive hash等...
有以下几个测试 Case: 正则表达式/.qt/g只可以匹配到bqt 正则表达式/.qt/gs或/(?s).qt/g可以匹配到bqt和\nqt(\n表示一个换行符) 正则表达式/.*qt/g可以匹配到bqt和qt(前面没有换行符) 正则表达式/.*qt/gs或/(?s).*qt/g可以匹配到整个结果(默认启用贪婪匹配导致的) ...
