　　活动摘要：The increasing popularity of social media has led to exponential growth in user-generated content (UGC), such as consumer-generated product reviews, that could be highly beneficial for market intelligence. Due to the large volume and unstructured nature of UGC, it creates both a unique opportunity and notable challenges for academics and practitioners. To advance market structure analyses, this study combines marketing theories and advances in computational linguistics to obtain deeper consumer and market insights from free-form product reviews. An innovative text analytics method integrates text mining and sentiment analysis techniques to automate market structure analyses. To demonstrate the validity of this method, the authors conduct an intensive empirical study and implement a prototype system to analyze tablet computer reviews from Amazon.com. The results show that the proposed method provides high validity compared with extant market structure analysis methods and can explain market competition using a multi-attribute approach. The method offers additional insights, such as consumer product usage situations, multilevel attribute hierarchy, and consumer sentiments toward product attributes.
