Word clouds work in a simple way: the more a specific word appears in a source of textual data (such as a speech, blog post, or database), the bigger and bolder it appears in the word cloud.
A variety of word and tag cloud generators are freely available on the internet and the process for creating them is straightforward. Evaluators can simply import text (for example, a set of interviews) into a text box and the tool creates a graphical representation of the words. Most word cloud generators have features that allow users to change colors, font, and exclude common or similar words.
