有没有办法生成某种文本的哈希值以进行比较？
我不知道我想要的是否可能，但是是这样的：
假设我有几个短语，我想生成可以代表文本的该短语的某种较少的字符串。我将把它应用到很多文本中。之后，我比较生成的字符串，看看一个文本与另一个文本有多少不同。
我不需要知道差异在哪里或检索原始字符串，我只需要它来比较字符串。
有这样的事吗？我使解决方案变得复杂？
I don't know if what I want is possible, but is this:
Suppose I have a few phrases, I want to generate some kind of fewer string of that phrase that can represent the text. I will apply this for a lot of texts. After that, I compare the resulting strings to see how much different are one text from the other.
I don't need to know where are the differences or retrieve the original string, I only need this to compare strings.
There is something like this? I'm complicating the solution?

有这样的技术，称为模糊散列。看看 ssdeep。您可能还对
使用上下文触发分段散列识别几乎相同的文件一文感兴趣。There is such technique and is called fuzzy hashing. Take a look at ssdeep. You also might be interested in the paper
