How Low-rating Restaurants Crack Business

摘要

This work is focusing on "Yelp" businesses. The main idea is to analyze the data from the Yelp web site. These two methods are used for grade prediction and feature selection: multinomial logistic regression and random forest. In conclusion, the results of the two methods are mostly the same with acceptable difference. Although reviews are too sophisticated to generate, some trials are included in the very last section for interest because it is a hot topic these days and it is indeed very effective for rating prediction.
