After the ex-National Security Agency contractor Edward Snowden1 disclosures of the National Security Agency surveillance of Americans’ online and phone communications, the Pew Research Center2 administrated a panel survey to collect data concerning Americans’ opinions about privacy and security. This survey has mixed types of qualitative questions (closed and open-ended). In this context, to our knowledge, until today, no research has been applied on the open-ended part of these data. In this chapter, first the authors present their findings from applying sentiment analysis and topic extraction methods; second, the authors demonstrate their analysis to sentiments polarities; and finally, the authors interpret the semantic relationships between topics and their associated negativity, positivity, and neutral sentiments.
