This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).This article has been retracted at the request of the authors; serious errors had been introduced within the data set presented and, as such, the authors have decided to retract the paper.Error summary is outlined below:1. The dataset was divided into training set, validation set and testing set. The training set and validation set were used to tune the parameter. According to the authors this is an overfitting and can mislead the readers.2. The compared baselines are not strong enough for fair comparison. The code was not requested from the original authors, but algorithms have been implemented.3. The bag of words model is not trained suitably. The model was trained with the used dataset and the performance has been evaluated on this dataset. Authors think this is an overfitting and makes the comparison untrustworthy.

本文已被撤回：请参阅Elsevier关于文章撤回的政策（https://www.elsevier.com/about/our-business/policies/article-withdrawal）。在给出的数据集中引入了严重的错误，因此，作者决定撤回该论文。错误概述如下：1。数据集分为训练集，验证集和测试集。训练集和验证集用于调整参数。根据作者的说法，这太过合适了，可能会误导读者。2。比较的基线不足以进行公平比较。原始作者未要求提供此代码，但已实现算法。3。语言袋模型训练不当。使用所使用的数据集对模型进行了训练，并且已经对该数据集进行了性能评估。作者认为这是一个过拟合，因此无法进行比较。
