最长公共子串、最长公共子序列的Java实现与NLP应用
前言以前HanLP使用“最短编辑距离”来做推荐器,效果有待提高,主要缺点是根据拼音序列的编辑距离推荐的时候,同音字交错很常见,而编辑距离却不那么大。这时我就在寻求一种补充的评分算法,去评判两个句子在拼音这一维度上的相似程度。区别最长公共子串(Longest Common Substring)指的是两...

2.3.1 LONGEST PREFIX 最长前缀
解题思路: 1.简单动态规划。 2.纠结的边界处理,不建议采用dp[i]表示s前i个字符能否取得这种方法。用这种方法实现字符串储存的时候会比较麻烦。而且如果存储不对边界处理会非常麻烦……(最先我采用的是这种方法,结果WA 4次,多次处理还是有长度为0和长度为1的情况无法分辨,最终放弃)...
