Online review structure, not just sentiment, predicts what readers find helpful

A study of nearly 200,000 Amazon reviews shows that the usefulness of online product reviews depends not only on what is said, but on how the information is structured. The researchers, from the Universities of Cambridge and Queensland, studied Amazon reviews for products ranging from clothing to food to electronics. They found that how the information is organized matters as much as what is said, and that different review structures are more or less helpful, depending on how highly the reviewer has rated the product.
