doublearraytrie's Introduction

DoubleArrayTrie

双数组字典树的实现,可用于敏感词过滤,关键字提取等。

词语查询的时间复杂度为 O(n)

本双数组实现字符串查找的基本算法是

next_sub = base[cur_sub] + next_var_seq

check[cur_sub] = pre_sub

主要是字符之间的状态传递实现

使用方法\ KeyWordResult result = KeyWordMatch.matchKeyWord("代理办证前途无量");\

if (result.isContain) {

for (String keyword : result.getKeywords()) {


	System.out.println(keyword);
	
	
}

}

首字数量383 ------------ 初始加载时

总字数1278 ------------ 初始加载时

8192 ------------ 初始加载时

8192 ------------ 初始加载时

敏感词:办证 ------------ 文本敏感词

未完成功能:

1 词级别控制

新增: 1 新增替换文本接口,如关键字是 关键字 , 文本为 某某关键字的应用 ,通过[]符号替换后为 某某[关键字]的应用
