As online reviews are becoming increasingly important for newly opened restaurants, such reviews are frequently manipulated at the startup stage of these businesses, which negatively impacts their credibility. To establish the attributes of online reviews that might be manipulated, we conducted exploratory research with a total number of 4,450 data from Yelp.com. The findings indicate that online reviews of newly opened restaurants show a time trend in which there are less negative sentiments and fewer words reflecting extreme reviews than long-running restaurants. Our findings provide five major core propositions and five sub propositions we use to advance our hypotheses. We postulate theoretical implications and practical insights in the discussion of this study.

随着在线评论对于新开业的餐厅变得越来越重要，此类评论在这些业务的启动阶段经常被操纵，从而对其信誉产生负面影响。为了确定可能被操纵的在线评论的属性，我们使用Yelp.com上的4,450个数据进行了探索性研究。调查结果表明，新开业餐厅的在线评论显示出一种时间趋势，与长期经营的餐厅相比，负面情绪和反映极端评论的词语更少。我们的研究结果提供了五个主要的核心命题和五个子命题，可用于推进我们的假设。在本研究的讨论中，我们假设理论意义和实践见解。
