Analysis of the online public opinion on the web platform TripAdvisor on Spain's industrial mining heritage, by structuring the data for sentiment analysis

It is more difficult to know how visitors receive this experience, whether on social networks or on the Trip Advisor platform, which specialises in this field. This article analyses the sentiment of these visitors using a novel methodology and computer applications.
