algorithm for determine the similarity between two string

Somebody know an algorithm for determine the similarity between two string

for example:

string 1: "Hello what is your name?, where are you from?"
string 2: "Hello man, where are you from?"

In this case I think that this two string has 75% of similarity.

However, if you know an algorithm that do that I'll appreciate very very
much
