Review helpfulness is attracting increasing attention of practitioners and academics. It helps in reducing risks and uncertainty faced by users in online shopping. This study examines uninvestigated variables by looking at not only the review characteristics but also important indicators of reviewers. Several significant review content and two reviewer variables are proposed and an effective review helpfulness prediction model is built using stochastic gradient boosting learning method. This study derived a mechanism to extract novel review content variables from review text. Six popular machine learning models and three real-life Amazon review data sets are used for analysis. Our results are robust to several product categories and along three Amazon review data sets. The results show that review content variables deliver the best performance as compared to the reviewer and state-of-the-art baseline as a standalone model. This study finds that reviewer helpfulness per day and syllables in review text strongly relates to review helpfulness. Moreover, the number of space, aux verb, drives words in review text and productivity score of a reviewer are also effective predictors of review helpfulness. The findings will help customers to write better reviews, help retailers to manage their websites intelligently and aid customers in their product purchasing decisions. 相似文献

The Book Industry Study Group and The Idea Logical Company carried out an online survey to capture publishers’ comments on
how market conditions were changing and what they are doing differently as a result of the economic pressures in the consumer
market. About 250 individuals responded to the online survey. Interviews were carried out of more than a dozen executives
at large and small publishers and their accounts to get further insights. The goal was to identify what are the sales conditions
for trade book publishers today and what publishers are doing to change sales and marketing and even editorial practices to
accommodate changing times. What we have learned from that joint effort is reflected in this article. 相似文献

This article introduces a selection of presentations from the 21st International Rights Directors Meeting held at the 2007
Frankfurt Book Fair It offers an overview of a variety of issues related to negotiating digital rights, in particular, and
the development of digital publishing, in general. Topics covered include current business models, opportunities for licensing,
and methods for negotiating contracts. Publishers are sanguine about the possibilities; though acknowledge that the digital
rights business is still in its formative stages. Agents and author advocates are concerned that digital advances may lead
to devaluation of writer’s works. Downloadable audiobooks have already created a new market, though e-books have yet to gain
traction and are awaiting a device or software application that make them available to a wide audience. 相似文献
