Data was collected through a survey launched in 11 countries, in three continents. The survey was translated into local languages, and small adjustments were made to questions where necessary, to reflect and adapt to the different contexts (e.g. specific containment measures).
The analysis and visualization of results depend on the type of question they refer to. For multiple-choice questions, results are represented quantitatively through graphs and charts reporting either the absolute or the relative (percentage) numbers.
We analyzed answers to open-ended questions through NLP (Natural Language Processing) tools, in order to extrapolate relevant key concepts. For each open-ended question, we selected the 100 most relevant key concepts using the Keyphrase Digger (KD) tool. The key concepts have been manually grouped into topics, and they have been visualized according to their frequency. The areas of the circles represent the frequency of the selected topics and key concepts.
