向量空间模型由Salton-Wong-Yang在20世纪70年代提出,并被用于文献的查重和检索,由于其基本原理简单而受到广泛应用。本文以国内三个大型电子网络企业为例,将此数学模型应用到实测数据,并用来衡量这些实测数据之间的线性相关程度。研究发现,上述三个企业的营收与我国消费者的消费能力呈现极强的关联,且数据中没有出现表现异常的个例。Salton, Wong, and Yang proposed the vector space model in the 1970s, and have been widely used for literature plagiarism detection and retrieval due to its simple basic principles. This paper takes three large domestic electronic network enterprises as examples, applies this mathematical model to turnovers, and uses it to measure the degree of linear correlation between these turnovers. This study found that the revenue of the three companies mentioned above is strongly correlated with Chinese consumers’ consumption ability, and there are no abnormal cases in the data.
