摘要:

由于电子商务网站和在线商店的激增,评论有用性的建模和预测变得更加突出。由于产品的功能无法在购买前进行测试,因此人们通常依赖于不同类型的用户评论来决定是否购买产品。然而,高质量的评论可能会被埋在大量评论的深处。因此,根据评论质量向客户推荐评论至关重要。由于没有评论质量的直接指示,大多数评论使用“Y中的X”用户发现评论有助于获得评论质量的信息。然而,这种方法破坏了有用性预测,因为不是所有的评论都有统计上丰富的投票。在本文中,我们提出了一个神经深度学习模型,可以预测评论的有用性得分。该模型基于卷积神经网络(CNN)和上下文感知编码机制,可以直接捕获单词之间的关系,而不管它们在长序列中的距离。我们在人类注释数据集上验证了我们的模型,结果表明我们的模型在有用性预测方面明显优于现有模型。

英文摘要:

Modeling and prediction of review helpfulness has become more predominant due to proliferation of e-commerce websites and online shops. Since the functionality of a product cannot be tested before buying, people often rely on different kinds of user reviews to decide whether or not to buy a product. However, quality reviews might be buried deep in the heap of a large amount of reviews. Therefore, recommending reviews to customers based on the review quality is of the essence. Since there is no direct indication of review quality, most reviews use the information that ''X out of Y'' users found the review helpful for obtaining the review quality. However, this approach undermines helpfulness prediction because not all reviews have statistically abundant votes. In this paper, we propose a neural deep learning model that predicts the helpfulness score of a review. This model is based on convolutional neural network (CNN) and a context-aware encoding mechanism which can directly capture relationships between words irrespective of their distance in a long sequence. We validated our model on human annotated dataset and the result shows that our model significantly outperforms existing models for helpfulness prediction.
