Reviews of products may be analyzed, and statements about the products may be made based on the analysis. Non-professional reviews (e.g., reviews of products written by ordinary consumers of those products) are often difficult to interpret, because different reviewers may apply different standards. When a large number of reviews are available, the reviews can be analyzed statistically to make comparative statements about the products or services reviewed. Sentiments expressed in the reviews may be assigned numerical values. These numerical values for specific products, or classes of products, may be analyzed statistically to determine how the sentiments about a specific product compare with the sentiments about a larger class of products. Using this analysis, a statement can be made, such as, “This television has very good picture quality compared with other televisions of the same price.”
