| 摘 要： | 本文提出了基于LDA主题模型和直觉模糊TOPSIS的农产品在线评论情感分析方法。该方法使用情感词典对在线评论进行情感倾向分析，并计算农产品的积极情感值；运用LDA主题模型计算各个属性的权重，结合直觉模糊TOPSIS方法计算农产品的综合评价值；采用SPSS统计分析软件进行有效性检验。结果表明，综合评价值与月销售量、积极情感值呈显著的正相关性，说明该方法具有合理性，为挖掘农产品在线评论中的情感信息提供一种新的思路。

| Abstract: | In this paper, an emotional analysis method based on LDA topic model and intuitionistic fuzzy TOPSIS for agricultural products online reviews was proposed. The method USES the affective dictionary to analyze the emotional tendency of online comments and calculate the positive emotional value of agricultural products. The LDA thematic model is used to calculate the weight of each attribute, and the comprehensive evaluation value of agricultural products is calculated with the intuitive fuzzy TOPSIS method. SPSS statistical analysis software was used to verify the validity. The results show that the comprehensive evaluation value has a significant positive correlation with monthly sales volume and positive emotional value, which indicates that the method is reasonable and provides a new idea for mining emotional information in the online evaluation of agricultural products. |
