String::AI is excellent in cases when some advanced comparison is needed ;)

In many cases it is sufficient however to use simpler methods. Their 
advantage is that it is easier to understand the code.

I found for instance that String::Similarity works very well for me.

One could try also, depanding on needs, one or more of the following:

String::Approx;
Algorithm::Diff
Text::Levenshtein
Text::WagnerFischer
Text::PhraseDistance
String::Compare
