Ranking Online Consumer Reviews

Sunil Saumya, Jyoti Prakash Singh, Abdullah Mohammed Baabdullah, Nripendra P. Rana, Yogesh k. Dwivedi

摘要:

产品评论被张贴在网上数百甚至在一些受欢迎的产品数千.处理如此大量的连续生成的在线内容对于买家、卖家甚至研究人员来说都是一项具有挑战性的任务。这项研究的目的是排名的绝大多数评论使用他们的预测有用的分数。使用随机森林分类器和梯度提升回归器,使用从产品的评论文本数据、产品描述数据和客户问答数据中提取的特征来预测有用性分数。该系统通过随机森林分类器将评论分为低质量和高质量。高质量评论的有用性评分仅使用梯度提升回归量来预测。低质量评论的有用性分数不会被计算出来,因为它们永远不会进入前k个评论。它们只是被添加到评论列表的末尾。拟议的系统提供了公平的审查位置上的审查清单页,使所有高质量的审查可见的客户在顶部。来自两个流行的印度电子商务网站的数据的实验结果验证了我们的说法,因为3-4个新的高质量评论和5-6个基于评论有用性的旧评论被放置在前十名评论中。我们的研究结果表明,包括从产品描述数据和客户问答数据的功能,提高了预测准确性的有用性分数。

英文摘要:

The product reviews are posted online in the hundreds and even in the thousands for some popular products. Handling such a large volume of continuously generated online content is a challenging task for buyers, sellers, and even researchers. The purpose of this study is to rank the overwhelming number of reviews using their predicted helpfulness score. The helpfulness score is predicted using features extracted from review text data, product description data and customer question-answer data of a product using random-forest classifier and gradient boosting regressor. The system is made to classify the reviews into low or high quality by random-forest classifier. The helpfulness score of the high-quality reviews is only predicted using gradient boosting regressor. The helpfulness score of the low-quality reviews is not calculated because they are never going to be in the top k reviews. They are just added at the end of the review list to the review-listing website. The proposed system provides fair review placement on review listing pages and making all high-quality reviews visible to customers on the top. The experimental results on data from two popular Indian e-commerce websites validate our claim, as 3-4 new high-quality reviews are placed in the top ten reviews along with 5-6 old reviews based on review helpfulness. Our findings indicate that inclusion of features from product description data and customer question-answer data improves the prediction accuracy of the helpfulness score.
