I. Introduction
With the widespread availability of the Internet, online reviews have emerged as a crucial information source for consumers to make informed purchase decisions [1]. As a result, the tourism industry has undergone rapid digital transformation, leading to the emergence of numerous destination travel platforms. Examples of such platforms include well-known Asian travel platforms such as KKday and Klook. These platforms provide locally curated travel experiences from around the world, and allow travelers to write reviews and provide feedback on their tour services and guides. This feedback can serve as a valuable reference for future travelers. TripAdvisor is the largest travel platform in the world [2], where users can share comments and photos about their travel experiences. The growth in the number of online reviews has led to their increasing significance in related research across various industries, including e-commerce, tourism, and marketing fields [3].
