Word2vec and k-means clustering were utilized to analyze and discover different online review corpora. To identify the best number of clusters, a series of experiments were conducted to find for the best Silhouette coefficient. For better analysis of k-means clustering, open coding was used to understand the significant qualitative codes. Based on the k-means clustering results, the following qualitative codes were identified: Time, staff, friendly, service, affordable, love, food, price, ambiance, good, great, relax. Analyses of the clusters show that quality service, tasty and affordable food and good atmosphere are the significant aspect that the online reviews are concerned. Based on the word2vec results, the researchers focused on the following words: Waiters, relax, great, ambiance, service and tasty.
