For each hotel in our dataset, we collected two types of information,
comprising (i) a detailed hotel description from Ctrip.com and
(ii) any review information, including review text, author, publishing
date, and customer rating. We collected all reviews for the hotels
from the time they joined Ctrip.com until the day of our data
collection, which gave a total of 40,424 user reviews. Table 2 provides
a summary of the data.
