摘要/Abstract

摘要： 电商平台信息对消费者的商品购买决策有显著影响。基于大体量的店铺与商品信息、在线评论文本进行信息融合并得出在线商品排序辅助消费者进行购买决策,具有重要的研究价值。针对上述问题,提出了一种融合多层次情感和主题信息的TS-AC-EWM在线商品排序方法,充分利用了评分信息与评论内容信息。首先,从计量与内容两个维度设计在线商品排序评价体系,体系包含4个计量指标与3个内容指标;其次,爬取各候选商品的计量指标与在线评论内容;然后,用融合主题与情感信息的TS方法以及基于追加评论的AC方法计算3个内容指标;最后,用熵权法确定指标权重,得出商品评分及排序。以京东微波炉数据集为例进行实验,证明了所提方法的可行性与有效性,因此该排序方法具有一定的现实意义。

Abstract: The information of e-commerce platforms has a significant impact on consumers' purchase decisions.It is of great research value to integrate the information of large-scale stores,commodity information and online review information and get online commodity ranking to assist consumers in purchasing decisions.To solve the problems,this paper proposes an online product ranking method TS-AC-EWM,which integrates multi-level emotion and topic information,and makes full use of scoring information and review content information.Firstly,the online commodity ranking evaluation system is designed from two dimensions of measurement and content,including four measurement indexes and three content indexes.Secondly,we crawl the measurement indexes and online review content of each candidate commodity.Thirdly,three content indexes are calculated by TS method,which combines topic and affective information,and AC method,which is based on appending comments.Finally,using the entropy weight method to calculate the index weight,commodity grading and sorting.Experiments on Jingdong microwave oven dataset prove the feasibility and effectiveness of the proposed method,so the ranking method has a practical significance.
