摘　　要：【目的】通过构建买家评论与卖家描述的相符度模型,对淘宝中卖家描述的商品特性与买家评论是否一致进行探讨。【方法】研究卖家的商品描述和买家的评论这两个文本信息,提取产品属性特征词和判断情感词极性,最后选取三家淘宝网店进行模型评估实验。【结果】发现B商家宝贝描述与买家评论相符度较高,A店次之,C店最差。其中,C店的"里衬"和"正品"两个产品属性,卖家描述与买家评论不相符。【局限】卖家描述的内容和买家评论的内容未能全面涉及,没有包括卖家的商品标题信息、卖家的图片说明信息以及买家秀中买家提供的照片信息。【结论】经过模型计算后的结果能够更细节、准确地反映出商品在哪些属性上相符以及多大程度上相符,进而更有效地辅助消费者进行决策。[Objective] This study discusses wheather commodity characteristics described by sellers are consistent with comments or not, by building the conformity model between description of sellers and comments of buyers. [Methods] Study the text of description and comments, extract the key attributes of products and determine polarity of emotional words, then select three Taobao shops to evaluate the model. [Results] The result shows that there are higher consistent degrees in B shop, A shop is the second, C shop is the worst. There are two attributes ＂in line＂ and ＂authentic＂ in C shop, which are not consistent with the comments. [Limitations] All the information from sellers and customers are not contained, such as title and picture information of products, and the photo information from customers.
