Machine Learning Idea – Word Cloud Labels?

Since for every answer there is a text sentence. I wonder. Is there some advantage to be made here? What if you don’t always want to use number labels. I mean. Different words together form sentences and augment each other as a meaning.

So my idea is to see if its possible use word clouds in machine learning. Here you don’t burden the algorithm to come up with proper english. Then the meaning of the word cloud is interpreted by the human. A word cloud is just a bunch of words with different sizes or number value attached to it.
