We proposed a new rule-based text analysis method to effectively summarize and transform unstructured user-generated content (online customer reviews) into an analysable form for tourism and hospitality research. To differentiate this method, we developed the Disintegrating, Summarizing, Straining, Bagging, Upcycling, and Scoring–DiSSBUS–algorithm which can address the following problems in previous approaches: (1) false identification of irrelevant aspect terms, (2) improper handling of multiple aspects and sentiments within a text unit, and (3) data sparsity. The algorithm’s distinctive advantage is to decompose a single review into a set of bi-terms related to the aspects that are pre-specified based on domain knowledge. Therefore, this algorithm can identify customer opinions on specific aspects, which allows to extract variables of interest from online reviews. To evaluate the performance of our confirmatory aspect-level opinion-mining algorithm, we applied it to customer reviews on restaurants in Hawaii. The findings from the empirical test validated its effectiveness.
