推荐基于.NetCore一款高性能敏感词检测开源库

今天给大家推荐一款高性能敏感词检测开源库。

项目简介

这是一款基于.Net开发的、高性能敏感词工具箱,支持繁简互换、全角半角互换,拼音模糊搜索等功能。功能强大、高性能,秒级检测亿级别的文章。

技术架构

1、跨平台:采用.Net Core3.1开发,支持跨平台。可以部署在Docker, Windows, Linux, Mac。

项目结构

使用方法

敏感词检测

过滤敏感词,可以设置跳字长度,默认全角转半角、忽略大小写、跳词、重复词、黑名单。返回结果包含:关键字、关键字起始位置、结束位置、关键字序号等信息。

string s = "中国|国人|zg人";string test = "我是中国人";StringSearch iwords = new StringSearch();iwords.SetKeywords(s.Split('|'));var b = iwords.ContainsAny(test);Assert.AreEqual(true, b);var f = iwords.FindFirst(test);Assert.AreEqual("中国", f);var all = iwords.FindAll(test);Assert.AreEqual("中国", all[0]);Assert.AreEqual("国人", all[1]);Assert.AreEqual(2, all.Count);var str = iwords.Replace(test, '*');Assert.AreEqual("我是***", str);

敏感词通配符检测

支持正则表达式类型:.?[]|,通过正则表达式可以进行模糊匹配,提升检测精准度。

string s = ".[中美]国|国人|zg人";string test = "我是中国人";WordsMatch wordsSearch = new WordsMatch();wordsSearch.SetKeywords(s.Split('|'));var b = wordsSearch.ContainsAny(test);Assert.AreEqual(true, b);var f = wordsSearch.FindFirst(test);Assert.AreEqual("是中国", f.Keyword);var alls = wordsSearch.FindAll(test);Assert.AreEqual("是中国", alls[0].Keyword);Assert.AreEqual(".[中美]国", alls[0].MatchKeyword);Assert.AreEqual(1, alls[0].Start);Assert.AreEqual(3, alls[0].End);Assert.AreEqual(0, alls[0].Index);//返回索引Index,默认从0开始Assert.AreEqual("国人", alls[1].Keyword);Assert.AreEqual(2, alls.Count);var t = wordsSearch.Replace(test, '*');Assert.AreEqual("我****", t);

拼音转换、繁简转换、数字转大小写操作

此工具箱,集成了繁体简体互转、拼音转换、首字母提取、数字转大小写,使用例子如下:

// 转成简体WordsHelper.ToSimplifiedChinese("我愛中國");WordsHelper.ToSimplifiedChinese("我愛中國",1);// 港澳繁体 转 简体WordsHelper.ToSimplifiedChinese("我愛中國",2);// 台湾正体 转 简体// 转成繁体WordsHelper.ToTraditionalChinese("我爱中国");WordsHelper.ToTraditionalChinese("我爱中国",1);// 简体 转 港澳繁体WordsHelper.ToTraditionalChinese("我爱中国",2);// 简体 转 台湾正体// 转成全角WordsHelper.ToSBC("abcABC123");// 转成半角WordsHelper.ToDBC("abcABC123");// 数字转成中文大写WordsHelper.ToChineseRMB(12345678901.12);// 中文转成数字WordsHelper.ToNumber("壹佰贰拾叁亿肆仟伍佰陆拾柒万捌仟玖佰零壹元壹角贰分");// 获取全拼WordsHelper.GetPinyin("我爱中国");//WoAiZhongGuoWordsHelper.GetPinyin("我爱中国",",");//Wo,Ai,Zhong,GuoWordsHelper.GetPinyin("我爱中国",true);//WǒÀiZhōngGuó// 获取首字母WordsHelper.GetFirstPinyin("我爱中国");//WAZG// 获取全部拼音WordsHelper.GetAllPinyin('传');//Chuan,Zhuan// 获取姓名WordsHelper.GetPinyinForName("单一一")//ShanYiYiWordsHelper.GetPinyinForName("单一一",",")//Shan,Yi,YiWordsHelper.GetPinyinForName("单一一",true)//ShànYīYī

性能对比

下面我们用户1000字字符串,进行10万次性能对比,看看对比结果,测试代码如下:

ReadBadWord();var text = File.ReadAllText("Talk.txt");Console.Write("-------------------- FindFirst OR ContainsAny 100000次 -------------------- ");Run("TrieFilter", () => { tf1.HasBadWord(text); });Run("FastFilter", () => { ff.HasBadWord(text); });Run("StringSearch(ContainsAny)", () => { stringSearch.ContainsAny(text); });Run("StringSearchEx(ContainsAny)--- WordsSearchEx(ContainsAny)代码相同", () => { stringSearchEx.ContainsAny(text); });Run("StringSearchEx2(ContainsAny)--- WordsSearchEx2(ContainsAny)代码相同", () => { stringSearchEx2.ContainsAny(text); });Run("StringSearchEx3(ContainsAny)--- WordsSearchEx3(ContainsAny)代码相同", () => { stringSearchEx3.ContainsAny(text); });Run("IllegalWordsSearch(ContainsAny)", () => { illegalWordsSearch.ContainsAny(text); });Run("StringSearch(FindFirst)", () => { stringSearch.FindFirst(text); });Run("StringSearchEx(FindFirst)", () => { stringSearchEx.FindFirst(text); });Run("StringSearchEx2(FindFirst)", () => { stringSearchEx2.FindFirst(text); });Run("StringSearchEx3(FindFirst)", () => { stringSearchEx3.FindFirst(text); });Run("WordsSearch(FindFirst)", () => { wordsSearch.FindFirst(text); });Run("WordsSearchEx(FindFirst)", () => { wordsSearchEx.FindFirst(text); });Run("WordsSearchEx2(FindFirst)", () => { wordsSearchEx2.FindFirst(text); });Run("WordsSearchEx3(FindFirst)", () => { wordsSearchEx3.FindFirst(text); });Run("IllegalWordsSearch(FindFirst)", () => { illegalWordsSearch.FindFirst(text); });Console.Write("-------------------- Find All 100000次 -------------------- ");Run("TrieFilter(FindAll)", () => { tf1.FindAll(text); });Run("FastFilter(FindAll)", () => { ff.FindAll(text); });Run("StringSearch(FindAll)", () => { stringSearch.FindAll(text); });Run("StringSearchEx(FindAll)", () => { stringSearchEx.FindAll(text); });Run("StringSearchEx2(FindAll)", () => { stringSearchEx2.FindAll(text); });Run("StringSearchEx3(FindAll)", () => { stringSearchEx3.FindAll(text); });Run("WordsSearch(FindAll)", () => { wordsSearch.FindAll(text); });Run("WordsSearchEx(FindAll)", () => { wordsSearchEx.FindAll(text); });Run("WordsSearchEx2(FindAll)", () => { wordsSearchEx2.FindAll(text); });Run("WordsSearchEx3(FindAll)", () => { wordsSearchEx3.FindAll(text); });Run("IllegalWordsSearch(FindAll)", () => { illegalWordsSearch.FindAll(text); });Console.Write("-------------------- Replace 100000次 -------------------- ");Run("TrieFilter(Replace)", () => { tf1.Replace(text); });Run("FastFilter(Replace)", () => { ff.Replace(text); });Run("StringSearch(Replace)", () => { stringSearch.Replace(text); });Run("WordsSearch(Replace)", () => { wordsSearch.Replace(text); });Run("StringSearchEx(Replace)--- WordsSearchEx(Replace)代码相同", () => { stringSearchEx.Replace(text); });Run("StringSearchEx2(Replace)--- WordsSearchEx2(Replace)代码相同", () => { stringSearchEx2.Replace(text); });Run("StringSearchEx3(Replace)--- WordsSearchEx3(Replace)代码相同", () => { stringSearchEx3.Replace(text); });Run("IllegalWordsSearch(Replace)", () => { illegalWordsSearch.Replace(text); });Console.Write("-------------------- Regex 100次 -------------------- ");Run(100, "Regex.IsMatch", () => { re.IsMatch(text); });Run(100, "Regex.Match", () => { re.Match(text); });Run(100, "Regex.Matches", () => { re.Matches(text); });Console.Write("-------------------- Regex used Trie tree 100次 -------------------- ");Run(100, "Regex.IsMatch", () => { re2.IsMatch(text); });Run(100, "Regex.Match", () => { re2.Match(text); });Run(100, "Regex.Matches", () => { re2.Matches(text); });

执行10万次性能对比,结果如下:

从测试结果看,此工具比C#自带的正则效率高8.8倍,如果数量量越大性能优势越明显。
