The word cloud is a fun and entertaining feature. To keep your word clouds clean and well structured, we apply certain rules and transformations to its display.
The transformations we apply
All accents on letters are discarded (except on Internet Explorer, due to a technical limitation);
Punctuations (, ; . ? ! :) are replaced with spaces;
Excessive spaces (more than one) are discarded;
All words are changed into all caps.
Therefore, the words "beyoncé", "Beyoncé", "BEYONCE", "BEYONCÉ", "beyonce" will all be identical in the word cloud and will be displayed as "BEYONCE".
The rules of display
An expression is preserved in its entirety if it consists of less than 30 characters. Otherwise, it is split at its spaces (or punctuations, as mentioned above);
The more recurrent a word, the larger it is displayed;
At most 50 words will be displayed on screen (in order of recurrence);
If the option "likes on answers" is active, every "like" on an answer will display it as if it had been sent once more. Therefore, 10 likes = the answer was sent 10 more times;
A word (or an expression) will not be displayed if it is part of the "stop words" list (see https://github.com/Alir3z4/stop-words/blob/master/french.txt and https://github.com/Alir3z4/stop-words/blob/master/english.txt). This prevents words like "in" to be displayed by themselves. Note that an expression like "tongue in cheek" will be displayed containing the "in" because it won't be split in two;
Aside from the transformations described above (concerning capital letters and accents), two words written in a different way will be displayed individually in the word cloud. Therefore, words like "school" and "schools" will be displayed separately.
Note that it's also possible for your audience to send emojis !
Turn on the "Multiple answers": this will allows participants to send in as many answers as they'd like, which is generally useful for displaying the different concepts as a word cloud;
Turn on the "word cloud" display: in this case, answers will be displayed as a word cloud immediately, prohibiting participants from sending answers on multiple lines (as might be the case for an open question);
Turn on the "Likes on answers": participants will then be able to see each other's answers and click on a little heart to upvote the answer of one of their peers. Functionally speaking, this is identical to sending the same answer. The advantage is that it prevents spelling errors that might occur if the answer is sent in multiple times, thereby causing these answers to be displayed separately.
Add a 30 character limit, which will prevent any answer from being split in two.
Phrase your question in a way that limits the form of a participant's answer. For example, by asking the question as "Today's student is...", you can influence the form the answers will take and prevent different spellings of the same answer.
Encourage participants to send in one word at a time (without any prepositions etc.) to avoid two similar answers from being considered separately (like "schools" and "the schools"), and remind them to "like" answers instead of sending in their own if it has already been mentioned.
Concerning the first two recommendations, we have added a "word cloud" interaction for which the "word cloud" display and the "Multiple answers" have been activated by default.
