Abstract:

Based on exploring the measure and text mining approaches of online reviews, most domestic
and foreign scholars have made much and rich empirical research on the relationship between online reviews
and sales in recent ten years. The conclusions of empirical study include positive correlation，negative
correlation and no significant, etc. It suggests that the impact of online reviews on sales depends not only
on the selection and measure of dimensions of online reviews from its own factors, but also on the products
category, different sources, cultural context and other situational factors. As the opinion mining of online
reviews usually dependence on the field knowledge strongly, it takes books as the object of study only, and
summarizes the empirical research on the relationship between online book reviews and sales systematically,
aims to provide new thought for the future empirical research.
