運⽤LDA主題模型探討戰地旅遊遊客評論之懷舊體驗

Using LDA topic modeling to explore nostalgic experiences in tourist reviews of battlefield tourism

本研究聚焦於戰地旅遊作為文化觀光的一種形式，特別探討遊客在金門戰地旅遊中的懷舊情感體驗與心理動機。過往文獻指出，戰地景點不僅承載歷史記憶與教育功能，更激發遊客對戰爭歷史與和平價值的情感共鳴。本研究運用「潛在狄利克雷配置模型」（Latent Dirichlet Allocation，LDA）進行主題分析技術，針對金門戰地旅遊的Google Maps遊客評論進行文本探勘，辨識出遊客關注的核心主題與感受。研究結果透過LDA主題模型歸納「軍事空間」、「軍旅生活」、「探訪親友」、「金門風光」、「特產與小吃」、「資訊媒體與交通」等六個主要主題。透過此一整合性研究模式，不僅豐富了戰地旅遊與懷舊觀光的理論研究，也為理解懷舊觀光中遊客價值轉化歷程提供了嶄新的理論視角與實務貢獻。

This study focuses on battlefield tourism as a form of cultural tourism, with particular attention to tourists’nostalgic emotional experiences and psychological motivations in Kinmen battlefield tourism. Previous studies have indicated that battlefield sites not only carry historical memories and educational functions but also evoke tourists’emotional resonance with war history and the value of peace. This study applies Latent Dirichlet Allocation (LDA) as a topic modeling technique to conduct text mining on Google Maps tourist reviews of Kinmen battlefield tourism, identifying the core themes and perceptions that tourists are concerned with. The results of the LDA topic model reveal six major themes:“Military Space,”“Military Life,”“Visiting Relatives and Friends,”“Kinmen Scenery,”“Local Specialties and Street Food,”and“Information Media and Transportation.”Through this integrated research approach, this study not only enriches the theoretical discussion of battlefield tourism and nostalgic tourism but also provides a new theoretical perspective and practical contribution for understanding the process of tourists’value transformation in nostalgic tourism.
