“…Qualitative methods are as follows: free heuristics method, which uses text connotations to obtain subjective knowledge of products [19]; content analysis method, which uses graphic information to examine destination images [20]; and multimodal discourse method, which uses construction to research the tourist image [21]. Conversely, the quantitative methods are as follows: cognitive mapping methods, which can better reflect the direction of the destination in the human brain, the surrounding environment, and the spatial correlation [22]; correspondence analysis method, which describes the correlation between two or more categorical variables at each level through principal component analysis [23]; intermediary test method, which verifies the antecedents in tourism image [24]; and mathematical models, such as regression analysis, importance-performance analysis (IPA), tri-component model [25][26][27], structural equation modeling (SEM) [28], and SEM in tourism [29,30]. Other studies have combined relevant theories for research, such as tourism discourse theory, grounded theory, and cultural memory theory [31][32][33].…”
