使用RegEx匹配相似单词

Question

大家好：我需要使用RexEx匹配相似的单词。例如，如果我有一个包含“自主”这样的词的模式，它应该匹配单词“自主”而不匹配“自主”。
示例代码：

void modify(string word) 
{ 
string input = "This island is a colony; however,it is autonomous and " + 
"receives no orders from the mother country, autonomy, N."; 
string pattern = @",\s" + word + @"\s[v|n|adj]\.";//word = "autonomous"; 
Regex reg = new Regex(pattern); 
string output = reg.Replace(input, "."); 
} 

Answer 1

这可能是你在找什么：

string s= "This island is a colony; however,it is autonomous and receives no orders from the mother country, autonomy, N.";; 
string pattern="autonomous"; 
Regex r=new Regex(@"\b(?!"+pattern+")"+pattern.Substring(0,pattern.Length/2)+@".*?\b"); 
r.Replace(s,"."); 

Answer 2

我不知道你将能够轻松地单独用正则表达式实现。

你应该看看模式匹配算法。有a similar question here涵盖此主题。
