Peter Norvig（Google 的研究主管）在这里提出了一个简单的方法，实际上效果非常有效：http://norvig .com/spell- Correct.html
它是用Python编写的，但翻译成其他语言相当简单（注意页面底部有一些翻译，但C#版本至少有一些错误）而且效率非常低，因此值得自己翻译成您需要的任何语言 - 这也是理解代码的好方法）。
Peter Norvig (Google's head of research) has a simple one here which actually works pretty effectively: http://norvig.com/spell-correct.html
It's in python but is fairly simple to translate to other languages (note that there are some translations at the bottom of the page, but the C# version at least has a number of bugs in it and is very inefficient, so it would be worth doing the translation to whatever language you need yourself - it's also a good way to understand the code).
