Frequently asked questions

In case of word cloud with stemming, words with the same stem are considered to be identical to each other or the purposes of the analysis. For example, computer, computational and computation have the same stem “comput”.  They will be considered to represent the same thing. If a word cloud is created without stemming these three words will be considered to be different from each other.

The polarity and emotion of each word are determined from well-known dictionaries used for this purpose.
