A state-of-the-art review of smart tourism research

Using a mixed-method approach combining qualitative and quantitative review techniques, this study analyzed 86 articles to identify state-of-the-art thematic research trends and articulate knowledge domains in the smart tourism research. In particular, the thematic analysis identified 11 themes from the current smart tourism research. Results of the co-citation analysis identified and visualized four knowledge domains as the theoretical underpinning of existing smart tourism literature, thereby supplementing, and complementing the findings of the thematic analysis. The constituents of each theme and knowledge domain were discussed to reveal critical gaps and suggest future research directions.
