==Approach:==

To generate the point word-clouds, the texts are analyzed using the natural language processing technique ''word2vec''. The resutling vector space is of very high dimensionality, thus cannot be easily visualized. To reduce the high dimensional space to three.dimensions the method ''t-distributed stochastic neighbor embedding'' is used, which keeps words close together that were close in the high dimensional space.

The resulting data is than imported into unity using a ''csv''-file and for every data-point a billboard-text of the word is generated. This process is repeated for every text.
