Online 스팀 카드 게임 are important in the evaluation of product quality. This paper seeks to assess information quality of online 스팀 카드 게임 using the TripAdvisor data for Korean hotels. We first estimate the review model developed by Dai, Jin, Lee, and Luca (2012) and show that high-quality 스팀 카드 게임 contain most of the information for the quality of hotels. Second, we assess the degree of distortions caused by fake 스팀 카드 게임 through numerical experiments and show that the distortions of fake 스팀 카드 게임 are serious. Third, we compare the simple average and weighted average aggregation methods. Weighted average method is better than simple average in finding the quality of hotels but it is more vulnerable to fake 스팀 카드 게임. Fourth, we suggest excluding low-quality 스팀 카드 게임 to deal with fake 스팀 카드 게임 and show that the benefit of avoiding serious distortions from potentially fake 스팀 카드 게임 is greater than the cost of losing information from low-quality 스팀 카드 게임.
