基于情感分析改进的在线评论分类研究
Research on Online Review Classification Based on Improved Sentiment Analysis
摘要: 面对海量的评论文本,单纯依靠人力对其进行分类,任务繁重且效率低下。文章提出一种基于情感分析改进的在线评论分类模型,将灰色关联分析和朴素贝叶斯算法相结合,考虑在线评论中的用户情感倾向,并将灰色关联分析结果作为一项特征属性嵌入朴素贝叶斯文本分类模型中。文章以京东商城Dyson V10 Fluffy Extra手持无线吸尘器为研究对象,对真实的在线评论数据进行挖掘,以检验模型的分类效果。结果显示,改进后的模型的分类性能明显领先于传统朴素贝叶斯分类模型,评价指标F值提升了3.06%,表明该方法在在线评论文本分类应用中具有一定的优势。
Abstract: In the face of a large number of comments, it is cumbersome and inefficient to classify them only by relying on human resources. This paper proposes an improved online comment classification model based on sentiment analysis, which combines grey correlation analysis with Naive Bayes algorithm to consider the user sentiment orientation in online comments, and embed the result of grey correlation analysis as a feature attribute into the Naive Bayes classification model. This paper takes the Dyson V10 Fluffy Extra handheld wireless vacuum cleaner of JD.com as the research object, and mines real online review data to test the classification effect of the model. The results show that the classification performance of the improved model is significantly better than that of the traditional Naive Bayes classification model, and the evaluation index F value increases by 3.06%. This method has certain advantages in the application of online review text classification.
