I Know What You Felt Last Festival

Festivals are an important leisure activity in the life of human beings. As a matter of fact, the organizers of festivals are interested in offering quality activities that allow them to position themselves in the entertainment market. To achieve this aim, the organizers use surveys to obtain a global opinion of the participants focusing on three key points: motivation, perception, and valuation. This method is tedious to perform and is timeconsuming. In this effort, we present a complete process that enables to automatically obtaining an overall appreciation of a festival from tweets shared by participants. The aim of this contribution is to replace the surveys by the textual analysis of messages posted on social networks. The precision obtained in our experiments highlight the relevance of our proposal. Keywords—Sentiment analysis; machine learning algorithms; festival; survey analysis
