And then, quantitative data were collected by distributing the questionnaires among the selected sample of the tourists. In the second phase, using Rough Sets Theory, the decision rules were extracted from the collected quantitative data. The research was conducted in the city of Tehran in autumn and winter of 2018. The statistical population of the qualitative part of the research consists of university experts and tourism industry activists, and 11 individuals were selected to take part in the present research based on purposeful sampling (considering some prerequisits such as academic knowledge or practical experience and expertise in social media marketing).
