Recent studies have assumed that OCRs could be untruthful since sometimes OCRs have made by business related people (e.g., owners and competitors) not real consumers, especially in the early stage when a company entered the market. Therefore, this study collected a total number of 4,450 OCRs of newly opened restaurants(NORs) and long running restaurants(LRRs) from Yelp.com and investigated (1) whether reviews of NORs has time trend and (2) whether there are different characteristics in reviews in accordance with the business stage of restaurants and review ratings. The results revealed that review ratings of NORs have U-shaped distribution, but the extremity of positive reviews follow a falling trend over time, and showed that the textual and source information of extreme rating reviews of NORs show different patterns from that of LRRs.
