区别在于后者没人用。下面给你贴个native speaker的看法以及一个抬杠的：

For native English speakers recognition is the only word that exists. Recognization is a word invented by scientists (probably not native English speakers) who have no proper knowledge of the English language. Recognization can only exist if you accept the existence of the word cognization. In the same way the verb will have to be recognizate.

Just a clarification:
Recognization is a historically valid variation of Recognition (there are quotes from the early 1700s using it). As English speakers got lazy, the longer form became obsolete to the point that some people deny its existence.
It was not "invented" recently, nor was it indicative of "not native English speakers." Claims of that sort are unsubstantiated, and anyone blindly insisting that recognition is the "only" form of the word is a militant reactionary in denial of historical reality.
