摘要:

在本文中,我们描述了用于评估在线评论有用性的卷积神经网络(CNN)的实现。据我们所知,这是第一次使用这种架构来解决这个问题。我们探讨了影响CNN性能的两个相关因素的影响:不同的词嵌入初始化和不同的输入审查长度。我们还提出了一种方法,将评级星级信息与评论文本相结合,以进一步提高预测精度。我们证明,这可以提高2%的整体精度。最后,我们在基准数据集上对该方法进行了评估,结果表明,相对于传统方法的已发表结果,仅使用评论文本训练的模型的准确性提高了2.5%,而使用评级星信息和评论文本相结合训练的模型的准确性提高了4.24%。

英文摘要:

In this paper we describe the implementation of a convolutional neural network (CNN) used to assess online review helpfulness. To our knowledge, this is the first use of this architecture to address this problem. We explore the impact of two related factors impacting CNN performance: different word embedding initializations and different input review lengths. We also propose an approach to combining rating star information with review text to further improve prediction accuracy. We demonstrate that this can improve the overall accuracy by 2%. Finally, we evaluate the method on a benchmark dataset and show an improvement in accuracy relative to published results for traditional methods of 2.5% for a model trained using only review text and 4.24% for a model trained on a combination of rating star information and review text.
