摘 要:[目的 /意义]针对传统方法的不足,提出一种以用户评论为数据源的企业产品级竞争对手识别方法。[方法/过程]首先,根据企业分析维度确定候选竞争产品,进行相关评论文本采集;其次,利用信息抽取技术从本企业产品评论中抽取用户较为关注的产品特征;然后,基于情感分析技术设计特征情感权重算法;利用该算法对本企业产品特征进行优劣势分析,获取优势与劣势特征集,完成待分析产品向量空间表示与相似度计算;分析计算结果,挖掘出与本企业产品优势相似及劣势互补的候选竞争产品,并选择优势相似且劣势互补的产品为主要竞争对手,其他优势相似的产品为次要竞争对手。在实证部分,选择"红米Note"手机为分析对象,以"淘宝""京东""中关村在线"多源评论为数据源,利用基于情感分析的竞争对手识别方法挖掘该产品的主要和次要竞争对手。[结果/结论]本文的基于情感分析的竞争对手识别方法能够实现企业产品级竞争对手的识别与分析。[Purpose/significance] For the lack of traditional methods, this paper presents an identification method for enterprise competitor based on user reviews.[Method/process] First of all, it chooses candidate competing products according to the analysis dimensions of enterprise, and grabs the relative reviews texts.Secondly, it extracts the product characteristics which users pay more attention from enterprise product reviews by information extracts technology, and designs a weight calculation algorithms of emotion features based on sentiment analysis technology.Thirdly, it analyzes the advantages and disadvantages of enterprise product characteristics by this algorithms, and then obtains the feature sets of advantages and disadvantages, to finish products vector space representation and similarity calculation.Finally, it digs up candidate competing products with similar advantage and complementary disadvantages to enterprise products according to the calculation results, and then chooses products with similar advantage and complementary disadvantages as the main competitors, and the other similar advantages products as the minor competitors.In the empirical part, it chooses "Red rice Note" phone as the analytic target, and uses the method which identifies competitor basecl on sentiment analysis to mine products of major and minor competitors based on the data from Taobao, Jingdong and ZOL.[Result/conclusion] This method can realize the identification and analysis of enterprise product level competitor.
