ANN - SimHash, a library to find the percentage of similarity between two given strings.

Hi, Guys

I just ported the C# version SimHash (http://simhash.codeplex.com/) to go, it's a library to find the percentage of similarity between two given strings, share it with you guys. 

I'm developing a website needs similar feature like stackoverflow, related topic of questions could instantly popup during entering a new one. And after a little research, I found that simhash is a good algorithm, so I just port a stable implementation from C# to Go. Hope it is useful.

You can get it from https://github.com/AllenDang/simhash

The usage is very simple, there is only one method actually, demo code is listed below.

needle := "Reading bytes into structs using reflection"
hayStack := "Golang - mapping an variable length array to a struct"

likeness := GetLikenessValue(needle, hayStack)
fmt.Println("Likeness:", likeness)

Yes, I know them, but they are not very promising.
